The answer is D, because carbon footprint is defined by the amount of carbon dioxide released into the air by human activities.
Answer:
Pigmented snails: A_B_; albino snails: A_bb, aaB_, aabb
This is an example of recessive epistasis. In recessive epistasis, two recessive alleles mask expression of an allele at a different locus. The 9:7 ratio observed in this question is a special case of epistasis called duplicative recessive epistasis, which means the presence of either aa or bb was sufficient to mask expression of the other gene. In this case, if snails had two copies of either allele a or allele b, pigment production was suppressed, resulting in albino individuals.
I think it is that the cytoplam divides
Answer:
1. cerebellum
2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the<em> medulla oblongata</em>). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the <em>corpus callosum</em>.
