VikaD [51]

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.

Explain why an organism cannot choose to have a mutation that would enable it to live more successfully in its environment.
vaieri [72.5K]

Answer:

Explanation:

An organism can't chose to have a mutation because it depends on the way they are born. If they are missing some type of mineral, (Protein, Vitamin, etc.) they will have a mutation because they're missing that. Well, something similar to a mutation is natural selection and genes. For example, there are some short and tall giraffes. The tall ones can reach the tree and the short ones can't so they die and the tall ones can reproduce and their offspring will inherit that trait

A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025

True or False. The complement system consists of several proteins that circulate in the blood and have the ability to enhance bo
nirvana33 [79]

Answer: False

Explanation: The COMPLEMENT SYSTEM consists of proteins synthesized in the liver. They are activated by inespecific harmful substance (antigen) and begins a cascade of proteins that finally forms an attack complex against bacteria.

The COMPLEMENT is part of the INNATE IMMUNITY, because it is an inherent response, something all humans born with, and it is part of the first defense barrier against any antigen. Part of the innate immunity are too: natural killer cells, neutrophils, monocytes, dendritic cells and macrophages.

On the other hand, the ADAPTATIVE IMMUNITY, is the response that the body develops after being exposed to an antigen before. It is like something that the body recognizes, and then "learns" how to act against it. Part of the adaptative immunity are: lymphocyte T and B, and the antibodies (substances called Immunoglobulins). The immunoglobulins (Ig) are glycoproteins present in the blood.
