The answer would be B. Cats.
Cats are the most advanced organisms between the options thus have the greatest amount of cell specialization.
Through my research I found matching questions with similar answers:
A) macrophages
B) antigens
C) antibodies
D) lymph
The best answer to fill in the blank would be the third option C) Antibodies which in the name anti means against, so since the word anti is the same as against, its a battle between antibodies and invaders, so that's why its C).
It is most likely due to the fact that the attenuation is the evolutionary relic, which by accident has remained does not support the actual reason of the dual control to regulate the operon.
Answer: Option E
<u>Explanation:</u>
In bacteria transcription and translation carries out at the same time so or the termination of transcription in premature phase in bacteria uses a special mechanism which is called as attenuation T.
he attenuation in bacteria is a regulatory mechanism. Trp operon is the group of codes of the components. These operons are the actual functioning group of the DNA.
I think the answer is -
when the body experiences a drop in temperature it forces the water molecules to move faster in order to break the hydrogen bonds and release energy as heat.
hope this helps you.
Answer is A. Desirable traits can be selected for and bred in offspring.
Charles Darwin found that there are variations among the individuals of the same species depending on the specific location. These variations may occurred may be due to environmental factors such as availability of food resources, climate differences, and predator-prey relationships.
The experiment with breeding pigeons was aimed to duplicate natural selection through artificial selection. As a result new trait was developed over a period of time. Therefore, desirable traits can be selected and bred in offspring.
