Hypothalamus works with the endocrine system and the nervous system. Thus, the correct option is A.
<h3>
What is endocrine system?</h3>
Endocrine system is the hormone-producing glands and organs release hormones directly into the bloodstream, allowing them to travel to tissues and organs throughout the body.
In the brain's, lower center region, The hypothalamus is present. It is a link between the endocrine and neurological systems. Chemicals produced by nerve cells in the hypothalamus regulate the release of hormones generated by the pituitary gland.
The hypothalamus collects data from the brain (such as ambient temperature, light exposure, and feelings) and delivers it to the pituitary gland. This information has an impact on the hormones produced and released by the pituitary gland.

Answer:
Statement that correctly states the evolutionary progression of hominids is that hominids first developed tools, then language and the brain increased in size.
Explanation:
The evolution of hominids occurred over a long period of time and included several steps in order for evolution to reach the Homo sapiens which is now known.
- <em>The first step in the evolution of hominids was standing -walking in an upright position on the lower limbs- which led to the release of the upper limbs.
</em>
- <em>The release of the upper limbs resulted in the use of the hands, which in turn led to the development of the first tools.
</em>
- <em>The development of language initially emerged with rudimentary sound-based communication, until it became a structured language.
</em>
- <em>During this process, the size of the brain -as well as the cranial capacity- increased as the hominid acquired new skills.
</em>
For this reason, the statement which best describes the evolution of hominids is that hominids first developed tools, then language and the brain increased in size.
Half life is the amount of time for one half of an isotope decay. Strontium-90 under goes a beta decay, which means that it will lose an electron forcing a neutron to turn into a proton. This decay process on Strontium-90 makes it have a half life of 28.8 days.
Answer:
It greatly affected the action of separase.
Explanation:
If there is a mutant form of the protein securin that cannot be cut or degraded, it greatly affected the action of separase because securin is responsible for the separation of two sister chromatids and this separation is only possible if the protein securin degraded. If the securin did not degraded, the separase is unable to separate the two sister chromatids which is necessary for the formation of daughter cells and then mitosis will not be completed.
