There are many factors. One can be the amount of predators that it has in the biome. Another can be human influence through things such as hunting or pollution or anything similar that might cause it to go extinct. One can be a change in climate or a decrease in food. Things that might decrease it are laws that prohibit or protect them. Conservation centers where they are bred can also help and decrease the probability.

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant
mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

victus00 [196]

Answer to Question 1:

True

Explanation

As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.

Question 2:

Many experiments require student-supplied items, such as _____.

1. Chicken

2. Fresh flowers

3. Distilled water

4. All of the Above.

Answer to Question 2:

The correct answer is 3.

Explanation

Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.

Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.

Cheers
