Answer: All of the given options.

Explanation:

The body generates immune response to every antigen that it encounters. Some of the responses are general response and some of the response are specific response.

The first line of defense is skin and mucous membrane which is a general response of the body in which the skin and mucous membrane helps in preventing the body from entry of organisms.

The second line of defense includes interferon and group of some cells like basophills, neutrophills ( types of leukocytes). They travel in blood and kills the pathogen present in blood.

The third line of defense includes B-cells and T-cells( type of leukocytes) which is specific to antibodies which means they will attack specific antigens and kill them.

Hence, all the options are correct.

7. Slime molds are fungus like protists, but they are not fungi. Why?
MrMuchimi

Answer:

Because they can move

Explanation:

Fungi cannot make food themselves so they depend heavily on hosts. Also fungi lack the proper cilia to move, so they use spores instead to "move".

In the case of slime mold, they are like an animal fungus per se. They are like Protozoa in their amoeboid plasmodial stage and similar to true fungi in spore formation.

Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.

lions [1.4K]

The type of lipid formed from rings of carbon atoms which regulate sexual function, blood glucose levels and are an important component in <u>cell membranes</u> are known as Steroids.

Steroids- A steroid is an organic molecule having four rings organized in a certain chemical configuration that is physiologically active. The two main biological roles of steroids are as signaling molecules and as critical elements of cell membranes that affect membrane fluidity.

Cell Membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The movement of materials into and out of the cell is controlled by the cell membrane.

Hyperventilation (rapid inhalation and exhalation) can result in respiratory alkalosis (increased blood pH). Why
Sonbull [250]

Answer:

Because lack of carbon dioxide causes the lack of acidic HCO₃⁻ which help to the regulation of the blood's pH.

Explanation:

Hello.

In this case, since the presence of carbon dioxide in blood regulates the pH of blood by maintaining it at about 7.35 to 7.45 (slightly basic) due to the equilibrium shown on the attached picture by which the yielded HCO₃⁻ ions low down the pH because the lack of CO₂ cause a condition known as respiratory alkalosis in which the pH of the blood significantly increases.

Thus, that condition causes symptoms such as confusion, hand tremor, lightheadedness., muscle twitching, nausea, vomiting and others.

Regards.

Explanation

The Neurologist is a doctor who has specialized in the study of diseases and disorders that affect the nervous system. When a person in the United States wishes to practice as a neurologist, they must follow some steps. You must first prepare to enter medical school by studying an area related to medicine such as chemistry, physics, biology, among others, which conceptually prepares you for the next step. In the second step, you must apply to medical school, where you will be put to the test with the Medical College Admission Test (MCAT) to measure your knowledge on this subject. Once you enter medical school, there you will learn for two years everything related to the necessary concepts and theory about medicine and later you will have to serve as a medical apprentice in university hospitals where you will apply what you learned.

Third, once the doctor has obtained his title that accredits him as a doctor, he must obtain one of the medical licenses that USMLE (United States Medical Licensing Examination) or COMLEX (Comprehensive Osteopathic Medical Licensing Examination of the United States ) doctors must have in the United States. Finally, the doctor must serve for three years as a resident in a hospital focused on an area related to Neurology and one more year of internship. According to the above, the correct answer is B. Licensing.
