Solutions having osmotic pressures less than those of body fluids are called Group of answer choices hyposmotic. hyperosmotic. magnosmotic. neosmotic. isosmotic. PreviousNext
Answers
Answer:
hyposmotic
Explanation:
Body fluids are in contact with cells. Cells are surrounded by a semi-permeable membrane, through which can pass certain solutes. If the concentration inside the cells is different from the body fluids, the water molecules will move from the more concentrated compartment to the less concentrated one. This process is called osmosis.
If the body fluids are more concentrated than cells, the solution is called hypertonic (body fluids are hyperosmic). If the body fluids are less concentrated than the cells, the solution is called hypotonic (body fluids are hyposmotic).

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
Answers
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).

Explanation:
As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.
The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.
Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

c. cerebral aqueduct
d. medulla oblongata
e. choroid plexus
f. pons; medulla oblongata; midbrain
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.

in order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many ___ bonds
Answers
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

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
Answers
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).
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.
Answers
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.

100% in the test ;)
Humus is made of Earthworms, nutrients and bacteria. So, the correct options are A, B and C.
What is Humus?Humus is the soil's black organic material that results from the breakdown of plant and animal debris. It is a type of organic material for soil. It has a lot of nutrients and keeps the soil moist. The Latin word for "earth" or "ground" is humus.
Humus is described as a dark organic substance that develops in soil as a result of plant and animal debris decomposing. It is organic and dark in colour because carbon has accumulated there. It contains elements that are crucial to maintaining healthy soil. Earthworms, nutrients, and microbes make up humus.
Because humus is a feature of loamy soils, the high concentration of nutrients in the soil is caused by humus. Humus reduces a substance's porosity by obstructing the pores that permit the passage of water and air.
Therefore, the correct options are A, B and C.

Describe how table salt dissolves in water in 300 words.
Answers
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.

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.
