The model demonstrating the importance of solar energy for life on Earth in which the student should make is a model of a local food web
All food chains begin by receiving the energy of the sun. This energy is captured by plants which are the producer link in the chain. Plants are able to utilize the light energy from the sun to produce food such as sugar from carbon dioxide and water.

In Guinea pigs, short hair is dominant and long hair is recessive. A
larisa86 [58]

Answer:

a. S represents allele for short hair while s represents allele for long hair.

b. Ss (male) × ss (female)

c. 50% Ss, 50% ss

d. 3 long hair (ss), 3 short hair (Ss)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The allele for short hair (S) is dominant over the allele for long hair (s).

a. Letter "S" will represent the allele for short hair while letter "s" will represent the allele for long hair.

b. According to this question, a heterozygous male is crossed with a long-haired female. The genotype of the male guinea pig is "Ss" while that of the female is "ss". (see attachment for the punnet square)

c. The possible genotypes of the offsprings in this cross are: Ss and ss, each carrying 50% each as they are produced in a ½ Ss: ½ ss.

d. Since 50% of the offsprings will be both short haired and long haired, If they have six babies, 3 of them will be short-haired while 3 of them will also be long-haired.

Refer to the paragraph about the formation of the isthmus of panama. the sister populations on opposite sides of the isthmus are
Dimas [21]
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.

r-ruslan [8.4K]

I like the word bats. It is cool. I also like the world "c o v i d 19" and "coronaviruses". I live getting colds cuz my mother treats me like her queen and puts a crown on my head. I am suffering from respiratory malfunction so please donate to my gofundme. Sars CoV 2 sucks. I spill over my shirt- NOOO! I go to the zoo for "zoo nosis" and then I sleep.
