The correct sentences are the following:

 A) Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics.

 C) Crossing-over causes a shuffling of allele combinations during meiosis as the alleles from each parent form new combinations on homologous chromosomes.

 E) When two bacteria are linked during conjugation, the donor cell passes DNA to the recipient cell which causes genetic recombination.

Explanation:

These three options are associated with the generation and preservation of genetic diversity

Describe the phases of the cell cycle. be sure to include the name of each phase and what is occurring within the cell during ea
julsineya [31]

Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.

 

<span><span>G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>

The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.

<span>Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.</span>

Lizette and her husband had her ova fertilized with his sperm in a laboratory and then implanted in her uterus. what form of ass
RideAnS [48]

In virto fertilization form of assisted reproductive technology.

<h3>IVF: Is the process painful?</h3>

It is comparable to a pap smear or even a vaginal ultrasound appointment. During this technique, an embryo transfer catheter and ultrasound guidance are used to transfer one or more embryos to the uterus. The entire operation will be visible to you on an ultrasound screen. This procedure is painless.

<h3>What distinguishes IVF from in vitro fertilization?</h3>

An IVF procedure involves surgically removing a woman's eggs from her ovaries and fertilizing them in a lab with sperm from a male partner or a sperm donor to produce embryos. (The term "in vitro" refers to the act of fertilizing an egg in a laboratory dish and is derived from the Latin meaning "in glass").
