Answer:The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.

Explanation:

Antibiotics are released by B cells to destroy the pathogen. The correct option is A.

Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical.

Antibodies, which are made by your immune system, bind to these foreign chemicals and drive them out of your body. Immunoglobulin is another name for an antibody.

Proteins called antibodies are created by the immune system in response to infection.

They play a crucial role in the body's defense mechanism because they work to eliminate pathogenic organisms and prevent them from invading human cells.

In response to antigens, the immune system either produces cells that go after the pathogen directly or produces specialized proteins known as antibodies.

Antibodies draw cells that will engulf and eliminate the infection by binding to an antigen. B cells and T cells, two types of lymphocytes, are the immune system's primary cells.

Thus, the correct option is A.

Answer:

Energy Supply for Muscle Contraction. Energy for the release and movement of the myosin head along the actin filament comes from adenosine triphosphate (ATP). Recall from the sliding filament theory that the actin and myosin chains slide past one another. The binding of ATP allows the myosin heads to detach from actin

Answer:

The stages of replication are Attachment, Penetration and Replication. The following information should be considered:

Explanation:

A bacteriophage means the virus that attacks bacterial cells. The lytic and lysogenic cycles comrpise of two methods of viral replication. In the lytic cycle, the virions generated are released from the host cell while on the other hand in the lysogenic cycle, viral nucleic material are existed into host nucleic material and also they are copied to daughter cells at the time when the host cell reproduces. The common steps in both cycles are given below:Attachment – in this step, the bacteriophage attaches itself to the host surface cell to insert its DNA into the host cell. Penetration – the virus inserts its DNA into the host cell via penetrating the cell membrane of the host cell.Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Answer:

1. connected by direct genetic relationship rather than by adoption or marriage

2. of or relating to biology or life and living processes

3. used in or produced by applied biology

Explanation:

Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.

Answer:

of or relating to biology or to life and living processes

Answer:

It is the primary mechanism for evolution.

In a dipstick urinalysis, red blood cells, glucose, and proteins all indicate abnormality but urea does not.

The components of normal urines include urea, chlorine, creatinine, and nutrients such as potassium, sodium, and other dissolved ions.

Proteins can also be present at a very minute level. However, the presence of red blood cells, glucose, and too much proteins is usually an indication of abnormality with an underlining health problem.

Hypothesis.

Explanation:

A hypothesis is a testable explanation for an event. For example, if you see a certain type of bird at your bird feeder, but never your neighbor's, you could come up with the hypothesis that that specific species of bird likes something that is present in your own birdseed, but not your neighbor's. This is easily testable by switching out different birdseeds and seeing which ones attract the birds, and serves to explain why the birds only appear at your bird feeder.

Explanation:

An actin gene in humans is 92 identical to the homologous actin gene in mice. An actin gene in human is 80% identical to the homologous gene.

Orthologous sequences provide useful data in taxonomic classification and phylogenetic analyses of organisms.

The sequence of genetic difference can be used to draft the relatedness of organisms. Two organisms that are very near related are likely to show very similar DNA sequences between two orthologs.

Thus,  An actin gene in human is 80% identical to the homologous gene.

Based on the video, Mosa picked Frog 3 because it's a father frog which has all the traits that the children possess but the mother frog didn't have.

Genetic variation can be defined as a terminology which is used to describe the difference in the deoxyribonucleic acid (DNA) sequence in each of the genomes of a living organism.

Just like every other living organisms that reproduce through se-xual reproduction, frogs get a single allele from each parent. Based on the video, it should be noted that Mosa picked Frog 3 because it's a father frog with all the traits that the children possess but the mother frog didn't have.

Answer:

If mitosis skipped any of the stages, it would result in a mutated cell. If the cell skipped Metaphase, it could make daughter cells that are different than the parent cells. If the cell skipped Telophase, the cell would not divide, and the parent cell would attempt interphase with another nucleus.

Explanation:

The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made.
