Answer:

Amount of air inhaled or exhaled per breathing stroke is called as tidal volume. Tidal volume is 400 ml for women while for men it is 500 ml.

Explanation:

In respiration, tidal volume is defined as the volume of air that a person inhales or exhales in one stroke of normal breathing.

The tidal volume varies in adult men and women. In resting condition, tidal volume is 400 ml for women while for men it is 500 ml.

This tidal volume varies with the requirement of the body. During intense physical exercise the amount of gas intake increases in order to full fill the requirement of body and hence the tidal volume increases.

C. Read the hypotheses below, and identify the

tiny-mole [99]

Answer:

Independent variable: Salinity/Salt concentration

Dependent variable: hatching rate

Explanation:

As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.

In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.

Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;

Independent variable: SALINITY/SALT CONCENTRATION

Dependent variable: HATCHING RATE

An acute non-contagious respiratory tract infection that produces severe pneumonia-like symptoms caused by bacteria that thrive

Darina [25.2K]

Streptococcus infection carries all the symptoms mentioned.

<h3><u>Explanation</u>:</h3>

<em>Streptococcus pneumoniae</em> and <em>Diplococcus pneumoniae</em> are the organisms that gram positive bacteria. These bacteria enters the respiratory system from droplet method propagation which is through aerosol or water droplet inhalation which are infected with these bacteria. These bacteria leads to the severe antigen antibody reaction inside lungs which leads to high rate of mucous secretion. This leads to formation of pneumonia.

These bacteria are mainly seen in tropical countries with warm climate and humid environment. These bacteria doesn't spread through contagious methods like touching. But the protection must be taken as these patients cough can contain lakhs of these bacteria which are enough to infect a healthy individual.
