Which process allows a mammal to continue togrow in size?
(1) mitosis of sex cells
(2) mitosis of body cells
(3) meiosis of sex cells
(4) meiosis of body cells

Answers

Answer: The correct answer is-

(2) mitosis of body cells.

Mitosis is a type of cell division in which a parent cell produces two daughter cells having same number of chromosomes as that of their parent cell.

It occurs through a series of 5 stages that are- Prophase, metaphase, anaphase, telophase, and cytokinesis.

It is responsible for the growth of organisms and the repair of damaged tissues (in case of multicellular organisms) as new, identical cells (that are identical to each other) are produced from the parent cell.

Thus, option 2) is the right answer.

Answer:

2) mitosis of body cells

Homework due tonight, please help!List the four types pf stem cell, give an example of each type, and explain how much each type can differentiate.

Answers

Answer:

Totipotent - Able to differentiate into any type of cell of the human body or of the placenta. For example, fertilized egg cells and the cells from the egg’s first few divisions.

Pluripotent - From totipotent cells, able to differentiate into almost any type of cell of the human body. For example, blastocyst cells

Multi potent - Can develop into more than one type of cell, but more limited than pluripotent cells. For example adult stem cells and cord blood stem cells

Unipotent - Can only differentiate in a single lineage. Skin cells are the most abundant type of these.
Embryonic stem cell- are harvested from the inner cell mass of the blastocyst seven to ten days after fertilization. 

Fetal stem cell- are taken from the germline tissue that will make up the gonads of aborted fetuses.

Umbilical cord stem cell- umbilical cord blood cells contain stem cells similar to those found in bone marrow. 

placenta derived stem cells- up to ten times as many stem cells can be harvested from a placenta as from cord blood

Adult stem cell- many adult tissue contain stem cells that can be isolated

What is the advantage of genetic recombination as a mode of reproduction in bacteria? less time finding other bacteria

higher rates of reproduction

more susceptibility to antibiotics

greater genetic variation

Answers

Bacterial genetic recombination is characterized by DNA transfer from one organism called donor to another organism as the recipient and the result is the production of genetic recombinants, individuals. Those recombinant bacteria have a greater genetic variation because they carry, not only the genes they inherited from their parent cells but also the genes introduced to their genomes. There are three types of mechanisms that create genetic variations in bacteria (through recombination):

1. Transformation-that occurs when bacterium takes up a piece of DNA floating in its environment,

2. Transduction-occurs when DNA is accidentally moved from one bacterium to another by a virus (bacteriophage) and

3. Conjugation- when DNA is transferred from one bacteria to another through a tube between cells.

 

Those mechanisms of genetic recombination together with short generation time and random mutations allow bacteria to evolve very quickly and for example, create resistance to antibiotics.
The correct answer for the question that is being presented above is this one: "greater genetic variation."  The advantage of genetic recombination as a mode of reproduction in bacteria is that it has greater genetic variation. The greater its genetic variation, the greater advantage of genetic recombination.
