Which is the most likely explanation for the change? the beetle population moved to a greener habitat. a natural disaster almost caused the extinction of the population. the beetle population’s food sources decreased dramatically. a mutation resulted in a new color of insect.
The correct answer is D ie. a mutation resulted in a new color of insect.
A mutation is a change in a gene's structure, which is how inheritance works. Deoxyribonucleic acid (DNA), a lengthy molecule made up of units referred to as nucleotides, is the substance that makes up genes. Each nucleotide is constructed around one of four distinct bases.Due to population genetic variability, the population of lady beetles has changed over the generations (also called genetic diversity).The color gene of insect carapaces is the gene that has undergone diversification in this instance. In this example, there are two alleles (one for the green color and the other for the yellow color).Hence , the answer to this question is option D

Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.
Example: Blastocyst cells.
Multipotent Stem Cells - They can only differentiate into closely related cells.
Example: Blood stem cell
Unipotent Stem Cells - They can only produce their type of cell.

Regulating hormones from the hypothalamus ________
Regulating hormones from the hypothalamus first enter into the hypophyseal portal system.
Are hormones regulated by the hypothalamus?The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.
It is the hypothalamus that produces the antidiuretic hormone and oxytocin, which will be secreted by the neurohypophysis.

You are a molecule of phosphorus. Choose a starting point in the phosphorus cycle and describe the process you would go through to move through the entire cycle.
Living creatures and the soil exchange phosphorus. Phosphates are taken up by plants from the soil and assimilated into organic molecules. Plants are consumed by animals, which then moves phosphorous up the food chain from one animal to the next. When an animal perishes and decomposes, phosphorus is released back into the soil.
The major pathway of communication between the right and left hemispheres is the.
Answer:
corpus callosum.
..............
Answer:
Corpus callosum
Explanation:
Actually, the left and right brain hemispheres may communicate with one another because to a thick bundle of nerves called the corpus callosum (Latin for "difficult body"). The corpus callosum, which is divided into several sub regions, connects various sections of the hemispheres. The corpus callosum is subdivided into the rostrum, genu, body, and splenium from anterior (front) to posterior (back). The brain's left and right frontal lobes are linked by the rostrum and genu. The hemispheres of the temporal and occipital lobes are connected by the body and spleen.
With over 200 million axons, the corpus callosum is the brain's biggest fiber bundle. It is made up of tracts of white matter fibers called commissural fibers. It has a role in several bodily processes, including the communication between the:
Cerebral hemispheres.Motion of the eye and vision.keeping the right balance of arousal and focus.The localization of touch.The different parts of our visual field, which independently process pictures in each hemisphere, are combined by the corpus callosum, which plays a crucial role in vision. By connecting the language centers of the brain with the visual cortex, it also enables us to recognize the objects we view. In order for humans to find touch, the corpus callosum also transmits tactile information—which is processed in the parietal lobes—between the two hemispheres of the brain.

10. Write the 2 Hardy-Weinberg equations. Use the equation to calculate the percentage of carriers of cystic fibrosis (a recessive disease, you must have two recessive alleles to have the disease) in a population if the frequency of cystic fibrosis births in that population is 9 in 1000.
Using the Hardy-Weinberg equations, the percentage of carriers of cystic fibrosis is 8.19%.
What are the Hardy-Weinberg equations?The Hardy-Weinberg equations describe the relationship between alleles in a population that is fairly constant.
The Hardy-Weinberg equations are given below as;
[tex]p^{2} + 2pq + q^{2} = 1 \\p + q = 1[/tex]
[tex]q^{2} = 0.009\\q = 0.09\\p = 1 - 0.09\\p = 0.91[/tex] Hardy-Weinberg equations
