Mitosis produces an exact copy of the original containing the same 46 chromosomes as the original cell
Meiosis produces 4 individual sex cells ( gametes) with only 23 chromosomes in each. This is so when a sperm cell and and egg cell meet the combine to make 46 total chromosomes with genes from each parent
Listening to Earth is an article about the study of the plate boundaries using hydrophones which make noises and different sounds.
<u>Explanation:</u>
Listening to Earth is an article which was written about the studying of the plate boundaries by Dziak and his team. Since it is tough to send people to the bottom surface of the ocean, they made use of hydrophones making them listen to various sounds.
These sounds are made by the movement and the motions of the plate boundaries from their original position which many a times lead to the earthquakes.
The biome that exist closest to the Earth's poles are descibed as polar
I think it depends on what it is about.. Did your teacher give you a punnett square or anything like that?
Answer:
1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.
Explanation:
Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:
Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes
Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.
Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.
Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.
Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.
Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.
