Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human
B. putting more red blood cells into circulation when atmospheric oxygen levels decline.
<h3>What are stomata?</h3>
The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.

Answer:
Explanation:
National Park Service has been keeping the native ponies on Ocracoke Island since the 1960s. It is believed that these ponies arrived and left by the ships. These ships required to lower their load thus they left the ponies on the Island. These ponies are known as Ocracoke ponies and also called as Banker ponies. These ponies share a link to old Spanish horses genetically. The unique characteristics of the ponies include one fewer lumbar vertebrae, greater bone density, short necks, wide foreheads, and one fewer rib.
<span>Grazers are basically animals that eat plants from the ground so an adaptation to prolong their life would be bitter taste, meaning the answer is D. bitter taste. That is because if animals eat them they see that they are bitter and they don't like it and they don't want to eat them so plants in savannas keep existing this way.</span>
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.
Hope this helped!
