Answer:
A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.
Explanation:
Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.
Spinalis thoracis extends the spinal column
Answer: The genotype of the generation resulting from the given P ( parental generation) is Aa that is all offsprings in the first generation will be heterozygous dominant.
The genotype of the parents is AA and aa and the gametes produced by these parents are A and a respectively.
When these gametes fuse, they result in the offsprings with genotype Aa. This represents a dominant phenotype due to the presence of dominant gene ( a gene that masks the expression of recessive gene and expresses itself), which is A in this case.
The human digestion starts in the small intestine gets the
most of the nutrients in your food, and your circulatory system passes them on
to other parts of your body to store or use.
When food enters the small intestine, villi along the intestine wall
along with enzymes help break down the food, and takes a long journey. The
stomach is right above the small intestine, and the small intestine is all
wrapped around, and isn't that thick. Nutrients from the food are released to
the whole body as energy. The small intestine brings the food to the large
intestine, which is five feet long and is near your pelvis, or hips. The large
intestine connects to the rectum, and then to the anus. In the large intestine,
all the water is absorbed as well as salt.
The correct answer to this question is letter B.its ability to form endospores in harsh conditions
The bacterium Bacillus anthracis, which causes anthrax, has been developed as a biological warfare agent. The ability that could have led to this is that its ability to form endospores in harsh conditions
Anthrax usually form endospores in non-bacteria friendly environments, meaning they could get into places that would otherwise be hygienic and infect individuals.
