Answer:
D. trait formation due to behaviors
Explanation:
It is obvious to see that the three animals, cat, whale, and bat, have the same basic structure of their forelimbs, but also that they have developed differently and have taken a new shape. The reason for this is a trait formation due to behavior. The cats ancestors were terrestrial, and the cats have remained terrestrial, walking on their four legs, and having the same shape and function as their ancestors. The whales had similar forelimbs, but their ancestors started to move more and more in water. As they did, they needed more muscle power, but also greater width of the forelimb so that they can move more easily and more efficiently in the water. This behavior has gradually resulted in a flat, strong, peddle like forelimb. The bat too had similar forelimbs to that of the cat, but its ancestors started to try to fly. The process was gradual, and it started with jumping, then longer jumps, development of skin between the fingers, elongation of the fingers, thus provide more area for development of wider skin area. This has resulted in developing a light, wide, skin dominated forelimb with elongated fingers, providing flight for the bat.
Answer:
I think its genotypes.
Explanation:
I learned about this in 7th grade and genotypes are what make up genes.
After 10 min it is 60 kilometers from its destination
Its bc plants can only take in so much nitrogen like compounds (nitrates, ammonium etc) to keep a stable ph level so ammonium is positively charged and nitrates are negatively charged they release hydrogen to equal the ph levels but since it’s already getting ammonium in the cycle it can’t receive more and the ratio must be compatible with the plants therefore not different.
Also, plants can’t take it in bc it needs the bacteria to break the ammonium down into a usable compound. Like nitrates.
I’m sorry if that was contradicting. I’m trying my best. :)
Answer:
A punnet square can be described as a diagram which depicts the outcomes of the genotype and phenotype of offsprings from a cross between parents. A cross in which a single trait is being considered is a monohybrid cross. A cross in which two traits are being studied is considered as a dihybrid cross.
The punnet square for such a cross can be made as follows:
RY RY rY rY
RY RRYY RRYY RrYY RrYy
RY RRYY RRYY RrYY RrYY
Ry RRYy RRYy RrYy RrYy
Ry RRYy RRYy RrYy RrYy
