Answer: Coal is a nonrenewable resource.
Answer:
The correct answer is option A. "directional selection".
Explanation:
Directional selection is a type of natural selection at which traits with extreme characteristics are selected over traits with medium characteristics. In this case, a long-term climatic change resulted in all seeds that are the fountain of food for finch becoming hard. This will result in a directional selection on bill size in the finch population, where large-billed birds will be selected over small and medium-billed birds.
Answer:
it is also transfer in chemical energy
First, we will elaborate the terms that are being used.
Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.
Homozygous:
The organism has two copies of the same allele
Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.
Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.
A: Heterozygous
B: homozygous recessive
C: Homozygous dominant
D: Homozygous recessive
E: Homozygous dominant
<span>The random changes a mutation causes to an organisms genetic code causes either
1. A different protein to be produced or
2. none at all
Mutations can either have a positive, negative or neutral (the vast majority) effect on the organism. (many times whether they are harmful or helpful depends on the environment.)
When a mutation makes an organism better able to survive that organism is more likely to survive and pass the mutated gene onto the next generation.</span>
