Answer;
Adrenal glands
Explanation;
-When confronted with a stressor, the adrenal glands respond by producing stress hormones, including catecholamines, cortisol, and epinephrine.
-In response to acute stress, the body's sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline.
-These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.
A.Cladograms, because those are diagrams, all the rest contribute to natural selection.
The 3 domains accepted by most scientists are archaea, bacteria, and eukaryote domains.
Answer:
1. the F' plasmid.
2. the bacterial chromosome
3. the bacterial chromosome
4. the F' plasmid.
Explanation:
The F' plasmid is an extrachromosomal DNA molecule composed of genes that act during the transference of genetic material. This plasmid can also be defined as an episome capable of transferring itself into another bacterial chromosome. The bacteria that contain F factor are named F+, while bacteria without this factor are called F-. During conjugation, the F+ factor interacts with F- cells to enable DNA transference among bacteria.
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
