If you know how meiosis and mitosis work, this answer is actually quite simple. Here's a little recap on how meiosis and mitosis work before I dive into your question.
Mitosis:
Basically what mitosis is doing is replicating your cells. Mitosis uses somatic cells, otherwise known as skin/body cells. These are just your everyday cells in your body basically, except for sex cells. It's actually what dust is made of. In mitosis, you begin with 1 cell, that has 46 chromosomes. This cell then duplicates, and then divides, leaving you with 2 cells with 46 chromosomes each. Now as a repeat, these cells that have duplicated are IDENTICAL.
Now onto meiosis.
Meiosis:
Meiosis uses gametic cells, instead of somatic like mitosis uses. Gametic cells are sex cells (sperm and egg). In meiosis, you start out with a cell that has 23 chromosomes from mom, and 23 chromosomes from dad. This cell then duplicates and divides like in mitosis, and then divides a second time. What you are left with is 4 haploid daughter cells. These cells are NOT identical, because a whole lot of other stuff is also going on during this process in which I did not explain since this is the short version. Basically, the sperm and egg combine, and then produce genetically different sets of chromosomes from each parent.
I hope this helped clarify and answer your question. If you are still confused, I have included some of my biology notes on the topic which also includes some pictures if that helps you understand a little better. There are also a whole bunch of Youtube videos on meiosis and mitosis you can watch which can also help if you are still confused on these processes and why they are different and what is even going on during them.
Also, if you are wondering what my color coding means in my notes, pink/red is for vocab words/definitions and blue is just topics. I also used the blue and pink to differentiate between the chromosomes from your mom and from your dad.
Answer:
The Hypothalamus
Explanation:
The Hypothalamus is the part of the brain that controls and regulates body temperature, sexual arousal, hunger, and thirst.
Replacing the aluminum core of an electromagnet with an iron core would make it to become a stronger electromagnet.
<h3>What is an electromagnet?</h3>
An electromagnet refers to a magnet that is produced by electromagnetic induction. The core of an electromagnetic determines the overall strength of the electromagnet.
Since aluminum is a weaker magnet than iron, replacing the aluminum core of an electromagnet with an iron core would make it to become a stronger electromagnet.

Endotherms are animals whose body
temperature is regulated mainly by internal bodily processes. Endotherms are
warm blooded animals such as birds and mammals that maintain a constant body
temperature independent of the environment. Endotherms require high quantities
of fuel to produce heat for their survival under low external temperatures.
