What does the biodiversity on Earth indicate about its organisms?
mixas84 [53]

A high biodiversity tally may indicate that some of its organisms may be able to survive drastic environmental changes. If there weren't at least a few organisms that contribute to biodiversity, most of the biotic Earth would be gone by now.

For example, woolly mammoths were unable to adapt to the up-and-coming warmth of the poles. Because they lacked biodiversity among their species, all of them died out and weren't able to adapt to the heat.

I hope I helped!

No stripe on the head (H) is dominant, a black stripe on the head is recessive. If dad's genotype is Hh, what are the odds that
olga55 [171]

The chance of the offsprings with stripe on head is 50%.

Option A.

<h3><u>Explanation:</u></h3>

Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.

So the genotype of the father which is given as Hh. He is heterozygous.

The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.

So the gametes from father is H and h. Whereas the gametes from mother is only h.

So the genotype of the offsprings are Hh and hh as 50% each.

So the probability of the offspring being striped head is 50%.

What are researchers doing to great whites in hopes of being able to learn more about their behavior patterns?
solong [7]

Answer:

tagging the sharks

Explanation:

To learn their behavioral patterns researchers are tagging the sharks. Doing so allows the researchers to track their movements individually and gather data as to how they move, where they migrate to, how many migrate together, etc. All this information is extremely valuable and when pieced together can shed light on why they have certain behavioral patterns or traits.
