Answer:
OH LOL I DID THIS IN 7TH GRADE
Explanation:
so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived
MY SENTENCE
It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.
Hope this helped mate :>
Answer:
B) 0.25
Explanation:
In the given individual, the genotype is aaBbCc. This indicates that the individual has two pairs of contrasting alleles. Thus it will produce four different types of gametes, abc, aBC, aBc and abC will be formed. Out of 4 types of gametes only one gamete namely, aBC is with two beneficial alleles. Thus, the proportion of two or more beneficial alleles is 0.25 (1 out of 4).
They should be carbohydrates, fats (lipids) and protein. they are labelled as primary food substances and they're essential to life. they can provide energy and raw material for life processing. although mineral ions and vitamin are important too, but they only need a small amount.
Answer:
Wild type
Explanation:
It refers to the phenotype that is found in nature. Naturally the form that is commonly seen in nature and is used for experiment is this type only.
This concept is useful in many experiment as it can be used as a model organism. Example: Drosophila melanogaster.
Manipulation of genes produces different type of phenotype other than wild type which is not generally seen in the nature.
