A type of lymphocyte called  NK cell detects cells with abnormal surface proteins and kills them.

<h3>What are lymphocytes?</h3>

One variety of white blood cell is the lymphocyte. They are crucial to the functioning of your immune system, which aids in the body's defense against sickness and infection. An extensive network of immune cells, lymph nodes, lymph tissue, and lymphatic organs makes up your immune system. Immune cells include lymphocytes. The two primary categories of lymphocytes are:

T lymphocytes (T cells): T cells direct your body's immune response and actively hunt down and destroy cancerous and infected cells.

B cells, or B lymphocytes: The B cell produces antibodies. Proteins called antibodies hunt down viruses, bacteria, and other foreign invaders.

Your body's immune system uses lymphocytes to combat cancer and invading viruses and germs (antigens). Your immune system benefits from lymphocytes' assistance in retaining every antigen it encounters. Some lymphocytes develop into memory cells after an encounter. Memory cells detect an antigen and reactbwhen they come into contact with it again. You don't contract illnesses like measles or chickenpox repeatedly because of this. Additionally, it explains why some diseases can be avoided through vaccination.

Sav [38]

The Retroviruses contain reverse transcriptase enzymes that make a dsDNA molecule from their ssRNA genome.

<h3>What is a Retroviruses?</h3>

A Retroviruses is a type of virus that has RNA instead of DNA molecule.

It contains reverse transcriptase enzymes that make a dsDNA molecule from their ssRNA genome.

These viruses are capable of causing the following diseases :

  • Acquired immuno deficiency disease (AIDs), and

  • Leukemia.

They are usually transmitted during close contacts.

Therefore, the Retroviruses contain reverse transcriptase enzymes that make a dsDNA molecule from their ssRNA genome.

Which scenario would cause a covalent bond to form?
nekit [7.7K]

Answer: A) Two atoms share electrons so they can fill their outer shells

Explanation: A covalent bond is a type of bond formed by sharing equal number of electrons between two non-metal atoms so that both of them can attain a stable octet or duplet structure of noble gases.

In covalent bonding, there is no loss or gain of electrons between atoms. For example, the formation of chlorine molecule, chlorine atom has seven electrons in its outermost shell, remaining one electron to attain an octet structure of noble gases. Two chlorine atoms share one pair of electron, each chlorine atom donating one electron to form a pair so that each atom in the chlorine molecule attains an octet structure..

den301095 [7]

Correct answer: C). Plant cells develop a cell plate while animal cells develop a cleavage furrow

Mitosis takes place in both plant cell and animal cell, the main difference in the cell division of plant cell and animal cell is observed in the formation of the daughter cell. During this stage animal cell form, a cleavage or cell furrow and plant cell form a cell plate, it does not form a furrow because they have a rigid cell wall. These cell plate in the center of the dividing cell and separate the two components.
