Gonadotropin-releasing hormone, luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short).
EXPLANATION
When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When this hormone reaches the pituitary gland, it releases two more hormones into the bloodstream: the LH and FSH. Although boys and girls do have these hormones, it depends on their sexual orientation the way these hormones work.
Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.
<h3>What is
muscle contraction?</h3>
The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.
Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.

Answer: Pigeon and duck.
Explanation:
From that side of the tree, you can see that the pigeon and the duck are closest together in the tree than the other organisms in the other options.
Answer:
without the graph presenting the data you can't really answer this but I assume since o Neil pass has a green environment the mice would be brown to match the ground
4.Metaphase
All of the chromosomes are aligned midway between the
spindle poles. A spindle is a dynamic network of microtubules that
attaches to and moves chromosomes during nuclear division. Microtubules
attach each chromatid to one of the spindle poles, and its sister to the
opposite pole.
