explain the genetic events that enable so many different cell types to arise from one unspecialized cell

Answers

Answer 1
Answer: All cells in the body have the same genetic material, e.g. they have same DNA. However, not all genes are active at the same time and in all cells. Thus, different genes are transcribed in different specialised cells. There are transcription factors that control which genes will be transcribed and which will be suppressed. Also, specialised cells in an embryo release signalling proteins that help in cell differentiation.

An act of fertilization in which genetic information is transferred between cells is called _____.xternal fertilization
internal fertilization
conjugation
pollination

Answers

Solution:

An act of fertilization in which genetic information is transferred between cells is called conjugation.

Image result for What is conjugation in science?en.wikipedia.org

Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient.

This is the required answer.

An act of fertilization in which genetic information is transferred between cells is called conjugation.

Conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.[1] This takes place through pilus

The cell transport process that is opposite of the three pictured is calleda. endocytosis.
b. osmosis.
c. exocytosis.
d. phagocytosis.

Answers

The correct answer for the question that is being presented above is this one: "c. exocytosis." The cell transport process that is opposite of the three pictured is called exocytosis. It is a process in which an intracellular vesicle moves to the plasma membrane and subsequent fusion of the vesicular membrane and plasma membrane ensues.

Which sequence represents a cross section of the bilayer

Answers

hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head



Answer:

The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.

A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.

The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.  

Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.
