Answer: a) true
Explanation:
The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.
The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.
During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.
Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
Are phylogenetic trees also known as <u>cladograms.</u>
<h3>What is cladogram?</h3>
The cladogram is an important graphic tool used in phylogenetic studies, and represents the evolutionary relationships between different groups of organisms, such as
- fish
- mammals
- reptiles
- and birds.
With this information, we can conclude that are phylogenetic trees also known as <u>cladograms.</u>

Answer:
hope this helps some
Explanation:
The theory that explains how this could have happened is called endosymbiotic theory. An endosymbiont is one organism that lives inside of another one. All eukaryotic cells, like your own, are creatures that are made up of the parts of other creatures. Mitochondria, the important energy generators of our cells, evolved from free-living cells.
A genome is an organisms complete set of DNA. DNA is what makes you, you. It provides the "blueprints" for what proteins need to be created in order to make each organism. Thus, the human genome is like the blueprints of a house as they are both the starting point for each new creation.
