Answer:
The first bar increases in length as compared to the second bar.
Explanation:
The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.

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.

Identify the structure you are consuming when you eat each of the following vegetables. Match the words in the left column to the appropriate blanks in the sentences on the right. a. stem b. taprootc. lateral buds d. modified steme. leaf (petiole and blade)f. petiole 1. Asparagus 2. Brussels sprouts 3. Celery 4. Spinach 5. Carrot 6. Potato
Answer:
a. stem 1: Asparagus
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.

assertion: empty milk pouches are biodegradable Reason: they cannot be used in biogas formation
Answer:
The pollutants like heavy metals, organic solvents present in pesticides exist in small amounts in the atmosphere. During the process of the food chain, the concentration of these pollutants progressively keeps on increasing through different trophic levels. For example, fish eats a lot of planktonic growth may retain the pollutants in their tissues, birds or people that eat the fish might concentrate the pollutants still more. This process of accumulation of pollutants at different trophic levels is called as biomagnification. So, the correct answer is 'Assertion is correct but Reason is incorrect'.
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.

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.

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.
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
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.

________________ best summarizes how Durkheim's approach to religion differed from that taken by Wallace.
Answer:
Durkheim underscored the common, public, and all-encompassing nature of religion. It also speaks to the definitions that it embodies and how it causes people to emote.
Explanation:
Durkheim is a sociologist of french origins who believed that society was more powerful than the individual.
This according to him, was so because society is held together by ideas that resonate across more than one individual. These ideas show up like norms, beliefs, and values which are subscribed to by many thus creating a collective consciousness. This collective consciousness makes it easy to predict how people generally are likely to behave either as a people or an individual.

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.
