Answer:

Option D, REM

Explanation:

In the rapid eye movement stage of sleep, a brain is quite active just like an awake person. Rapid eye movement occurs when a person visualizes a dream in a way that it seems to him/her as real. Therefore, the eyes dart in this stage. As a person darts his/her eye, a neurons in the medial temporal lobe of the brain will show some activity, showing that brain is consciously active.

Therefore, Mohammed is probably experiencing REM

Option D is correct

Why are antibiotics effective in curing diseases against some pathogens but not others?
Leya [2.2K]

Answer:

The correct answer is "I, II, and III".

Explanation:

The missing options of this question are:

I only

II only

III only

I, II, and III

The correct answer is "I, II, and III".

Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:

I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.

II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.

III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.

The city of Los Angeles wants to know if there is a connection between physical fitness and air pollution. Fifty volunteers from
zheka24 [161]

Answer:

Control group: volunteer stationary bike riders in a pollution-free chamber

Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles

Independent variable: exposure to air pollution

Dependent variable: The heart rates (physical fitness) of the volunteer riders.

Explanation:

In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.

N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).

In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).

The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.

MAXImum [283]

Answer:

chitin and murein

Explanation:

The chemical compounds that distinguish bacteria cell from yeast cell are  

chitin and murein

Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose

While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.
