<u>Answer:</u>
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
<u>Explanation:</u>
Background Knowledge:
DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.
Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.
The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.
Structural region is the region present between the promoter and terminator.
Answer of the question is:
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
Answer:
The 2 ways abiotic factors affect biotic factors are as follows:
- An alligator submerges itself under water to stay cool in the summer.
- A naked mole rat creates burrows underground.
Explanation:
Abiotic Factors:
All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.
Biotic Factors:
All living factors in an ecosystem i.e. the plants and animals.
Lets analyze all the options:
- A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
- Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.
Answer: radiation i think
I believe it would be chemical
