II. Sequencing Directions: Arrange the procedure/steps to fold a banana table napkin by writing 1 to 8 on the blank before the number.
Repeat the last step with the left side, folding the left tip up to the far corner, creating a diamond shape with a seam running down the center.
Fold the right end up to meet the far corner, ensuring the edge of this new fold lays on the centerline as shown.
Stand it up and tug at it where needed to even it up and out. If your napkins are too limp, then think of starch as a napkin and make them good and stiff round it.
Lay the napkin face down in front of you. Curl the left and right sides of the napkin up so they meet in the middle and tuck one into the other.
Fold the bottom of the napkin up about 2/4's of the way and press this fold down well. Fold the napkin in half diagonally. Orient the napkin so the open ends point away from you.
Fold the smaller triangle down so the point rests on the near edge of the napkin. Press.
Can you please answer it for me
Please if someone know
Explanation:
Lay a square napkin down on a clean work surface so that it's open all the way. Iron if needed.
STEP 2: FOLD IN DIAGONAL HALF
Grab a hold of the right hand corner nearest you and fold it over to meet the opposite upper left corner. Straighten out the edges so that they all meet up.
STEP 3: TURN IT
Turn the triangle so that the longest side is parallel to you and the table's edge.
STEP 4: FOLD IN
Fold the left corner in so that it sits JUST past the midway point of the long side of the triangle, like pictured.
STEP 5: FOLD IN AGAIN
Now repeat for the right hand corner.
STEP 6: FOLD OVER
Take the lower left corner and bring it in to the bottom midpoint of the now 'house' shaped napkin. Press the new left side fold down.
STEP 7: FOLD OVER AGAIN
Repeat on the right side.
STEP 8: FOLD UP
Take both bottom corners and bring them up to rest just below the top right corners. Press down the new folds.
STEP 9: CLOSE THE ENVELOPE
Take the top point of the envelope 'flap' and bring it down (or close it) to complete the envelope.
STEP 10: ADD A PERSONALIZED CARD
Use your envelope napkins to include a personalized 'letter' or card to each guest's plate. Some ideas for what this could be are:
holiday greeting card
menu
place card
family photos from past celebrations
holiday story or poem
coloring cards with pencil crayons for kids
game cards: trivia, scavenger hunt, etc

which piece of DNA would have the highest tm one with a cytosine plus guanine comment at t 30% or a cystonie plus guane content of 50% if both are heated under the same conditions
Answer:
50% G+C will have a higher Tm
Explanation:
The Temperature of Melting (Tm) refers to the temperature at which 50% of double-stranded DNA (dsDNA) is changed to single-standard DNA (ssDNA). In the double helix of DNA, Adenine bases always pair with Thymine bases through two hydrogen bonds, whereas Guanine bases always pair with Cytosine bases through three hydrogen bonds. In consequence, a DNA molecule containing a higher GC content is more stable than another DNA molecule containing a lower GC content. The Tm can be calculated as follows = 2 °C(A + T) + 4 °C(G + C) = °C Tm (this equation is useful for oligonucleotides of 14 to 20 base-length).
In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,250 pine trees in 1990 and 1,500 pines in 1995.
What was the average change of the size of the population from 1985 to 1995?
What was the density of pine trees each year that they were counted?
What was the average change of density from 1985 to 1995?
Answer:
Suppose that we have a given function f(x)
The average rate of change of the function between two values x₁ and x₂ is given by:
[tex]r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}[/tex]
a) We want to find the average (rate) of change on the size of population from 1985 to 1995.
We have that:
f(1985) = 750
f(1995) = 1500
Then we have:
[tex]r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75[/tex]
This means that the population of trees increases, in average, at a rate of 75 trees per year.
b) What is the density of trees each year that they were counted?
This will be equal to the quotient between the number of trees and the area.
1985: number of trees = 750 pines
area = 250 ha
Then the density is:
D(1985) = (750 pines)/(250 ha) = 3 pines/ha
So 1985, there were 3 pines per hectare.
1990: number of trees = 1250 pines
area = 250 ha
Then the density is:
D(1990) = (1250 pines)/(250 ha) = 5 pines/ha
1995: number of trees = 1500 pines
area = 250 ha
The density is:
D(1995) = (1500 pines)/(250 ha) = 6 pines/ha
3) now we want to get the average change between 1985 and 1995 in the density, this will be:
[tex]r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha[/tex]
So, on average, each year the number of pines per hectare increases by 0.3
The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow you to determine that this animal is haploid, n=2, and not diploid, 2n=2?
a. If these two mite chromosomes have different genes at different loci.
b. If the somatic cells in these mites undergo mitosis.
c. If these two chromosomes in the mite form tetrads during prophase I.
d. If this mite produces gametes containing only one chromosome each.
Answer:
The correct answer is - a. If these two mite chromosomes have different genes at different loci.
Explanation:
If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.

g 33. Humans are bipedal omnivores (we eat both meat and plants, and we walk upright.) What features of the skull reflect this
Answer:
Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.
Explanation:
Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.
The teeth on a skull are the most important indicators of what an animal eats, and it even shows if an animal is a predator or prey. Humans have different sets and shapes of teeth for different purposes making them an example of heterodont dentition.
The pelvis, knee, and foot bones should be the best to tell us about how an animal moves, however, the foramen magnum which opens for the spinal cord to pass to the brain, could also show whether how the animal moved.
Further studies of the genes in the region around the MHC locus identified C4 as a likely causative gene. A particular allele of C4 was significantly associated with schizophrenia. In addition, it was found that individuals with high expression of this allele of C4 had elevated risk of developing schizophrenia. Which of the following variants would be most likely to increase risk of schizophrenia from this allele?
a. a variant that decreases binding of an activating transcription factor to the C4 promoter
b. a 5’ UTR variant that destabilizes the C4 mRNA
c. a duplication of the C4 gene
d. a nonsense coding variant
Answer:
c. a duplication of the C4 gene
Explanation:
Schizophrenia is a disease that affects the brain, which is characterized by an imbalance of neurotransmitters and the presence of damaged brain tissues. In humans, the Complement component 4 (C4) protein is found at the neurons (i.e., cell bodies, dendrites and axons), which are the most common brain cells, and neuronal synapses. Moreover, gene duplication can increase gene expression when repressive mechanisms (e.g., DNA methylation at promoter sites) capable of silencing the expression of the duplicated gene are lacking. Recently, it has been discovered that a chromosome rearrangement associated with a tandem duplication of a genomic region that contains a C4 gene may contribute to schizophrenia risk by increasing the expression of this gene. In this example, a, b and d options are associated with a decrease in expression of the C4 gene, either by decreasing its transcription (options a and d) or by posttranscriptional mechanisms (option c).
Congestive heart failure (CHF) is an inability of the heart to pump sufficient blood to the body. One sign of CHF is excess fluid in the tissue spaces, known as edema. Describe the location of the edema if the left side of the heart fails, compared to the location of edema if the right side of the heart fails.
Answer:
Explanation:
When the left side of the heart (left ventricle) starts to fail, fluid collects in the lungs (edema). This extra fluid in the lungs (pulmonary congestion) makes it more difficult for the airways to expand as a person inhales. Breathing becomes more difficult and the person may feel short of breath, particularly with activity or when lying down.
When the right side of the heart (right ventricle) starts to fail, fluid begins to collect in the feet and lower legs. Puffy leg swelling (edema) is a sign of right heart failure, especially if the edema is pitting edema. With pitting edema, a finger pressed on the swollen leg leaves an imprint. Non-pitting edema is not caused by heart failure.
What transmission pattern would indicate that a trait may be transmitted through X-linked inheritance
Answer:
The transfer pattern of an X-linked inheritance can be either X-linked dominant or X-linked recessive.
Explanation:
X-linked inheritance is the term that refers to a gene capable of causing a specific characteristic or disorder and is located on the X chromosome. During the transmission of genetic material for the formation of another living being, this gene can be transmitted through the transmission standards known as X-linked dominant or X-linked recessive.
X-linked dominance inheritance occurs when the dominant gene is transmitted on the X chromosome, while X-linked recessive inheritance occurs when the recessive gene is carried on the X chromosome.
Different cell types and tissues express different sets of genes; for example, some genes are expressed primarily in the heart, others primarily in the brain, and still others primarily in the liver. This is possible because all of these cell types have ____________.
a. different sequence variants that control gene expression
b. different ordering of genes on chromosomes
c. different histone and DNA modifications
d. different sets of genes
Answer:
d.Different sets of genes.
Explanation:
A cell normally only expresses a percentage of its genes and various cell types are created by the expression of distinct gene sets. In addition, in response to changes in their environment, cells can alter the pattern of genes they express, such as signaling from neighboring cells.

g. hypothalamus
h. cerebrum
i. epithalamus
j. cerebrum
k. cerebellum
Explanation:
The brainstem is the posterior part of the brain that connects the cerebrum with the spinal cord. The brainstem can be divided into three parts: midbrain (i.e., mesencephalon), the pons (i.e., metencephalon), and the medulla oblongata (i.e., myelencephalon). The mesencephalon is a region of the brain composed of the tectum and tegmentum, which play fundamental roles in motor movement, auditory and visual processing. The corpora quadrigemina is found at the tectum region of the midbrain. The diencephalon is a small part of the brain located above the brainstem (between cerebral hemispheres); which contains the thalamus, hypothalamus, subthalamus, and epithalamus. In turn, the epithalamus is composed of the habenular nuclei, pineal gland, and the stria medullaris thalami. The cerebral aqueduct is a narrow channel (approx. 15 mm) in which the cerebrospinal fluid flows between the third ventricle and the fourth ventricle. The medulla oblongata is a long stem-like structure located in the brainstem of the brain, just in the place where the brainstem connects the brain to the spinal cord. The choroid plexus is a complex network of capillaries located at the cerebral ventricles of the brain, which serve to produce cerebrospinal fluid through ependymal cells that line the ventricles of the brain. The cerebellum is a major structure of the hindbrain and consists of the cerebellar cortex and a core of white matter having the cerebellar nuclei.

Describe how table salt dissolves in water in 300 words.
Answer:
salt disloves in 300 words
Answer:
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
Explanation:
When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation.
Discuss the internal and external structure of the testise
Answer:
External- The testes are covered by a tough membranous shell called the tunica albuginea. Within the testes are very fine coiled tubes called seminiferous tubules. The tubules are lined with a layer of cells (germ cells) that develop from puberty through old age into sperm cells (also known as spermatozoa or male gametes).
Internal -Each testicle is covered by tough, fibrous layers of tissue called the tunica. The outer layer is called the tunica vaginalis and the inner layer is called the tunica albuginea. ... There are about 800 seminiferous tubules tightly coiled within each testicle.

b. taproot: 5. Carrot
c. lateral buds: 2. Brussels sprouts
d. modified stem: 6. Potato
e. leaf (petiole and blade): 4. Spinach
f. petiole: 3. Celery
Explanation:
A plant stem is one of the structural axes of vascular plants that holds structures such as leaves, flowers, and fruits. The stem also transports water and dissolved (organic and inorganic) nutrients between the roots and the shoots. In some plants, the stem is modified in order to carry out other functions (e.g., storage, vegetative propagation, protection, etc). Potatoes are modified stems (i.e., stem tubers) that are connected by small stem sections known as stolons, and serve as food storage organs. A taproot is a central, and dominant root from which other roots sprout, which can be used by the plant to store water and food (e.g., in carrots and turnips). Lateral buds or axillary buds are meristematic regions growing from the axils of the leaves at the intersection of the leaf and stem, below the terminal bud. Leaves are composed of the 1-blade, also known as the lamina, which is the largest part of the leaf, and 2-the petiole, which is a stalk that supports the blade and connects it to the plant stem. Celery petioles play the same functions as a plant stem by acting as transport and storage organs.
