Answer:D. convergent evolution

Explanation:

Cacti or cactuses are member of the plant family and are often referred to as spiny plants that are usually found in the desserts.

Evolution - In biology, is described the ascent or descent in the characteristics of a species over a series of generations

and natural selection favors its modification.

When two species populations evolve to become more similar to each other we say say they have a convergence evolution.

Hint: Evolution of analogous structures is always an example of convergent evolution.

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.

A principal problem with inserting an unmodified mammalian gene into a plasmid and then getting that gene expressed in bacteria
vfiekz [6]

Answer:

introns will remain inside the bacteria

Explanation:

Introns  are the remains of an RNA transcript that do not involve in coding and hence they are trimmed off once the protein is translated from the RNA molecule.

Introns are found more commonly in eukaryotic genomes as compared to bacterial and archaeal genes

Group I introns have an ability to invade tRNA, rRNA and protein  through its intervening sequences however their insertion into genes is phenotypically neutral.
