Cells are the basic building blocks of life, which can join together to form tissues, while different groups of tissues join together to form organs. These organs are then connected together to form organ systems, such as the digestive system, which includes the stomach, esophagus, intestines and other organs.

Cells starting mitosis and meiosis begin with what set of chromosomes. True or False
Arisa [49]

Answer:

with haploid or diploid set of chromosomes. True

Explanation:

There are two types of cells in the body, haploid cells and diploid cells. The biggest difference is related to the number of chromosomes that each cell contains, while diploid cells contain two chromosomes (2n), haploid cells contain a chromosome (1n).

Features:

1. A haploid cell has only one set of chromosomes (n), while diploid cells have two sets of chromosomes (2n).

2. In humans, somatic cells are diploid, while gametes are haploid.

3. Diploid cells develop as a result of mitotic cell division, while haploid cells develop as a result of meiotic cell division.

4. Mitosis produces 2 identical daughter cells, where both stem and daughter cells are diploid. In meiosis, a diploid cell divides twice to produce 4 haploid daughter cells.

5. Humans and most animals are considered diploid organisms, while algae and fungi are examples of organisms that are haploid in most of their lives. Male bees, wasps and ants are also haploid.

Which observation would be the best evidence for a recent founder event or population bottleneck?
Bingel [31]
The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.
