Answer:

True

Explanation:

There are many substances that are toxic to our body and that can cause serious damage to our body, including death. These substances can be ingested, inhaled or enter the body by contact with the skin and cause damage even in small amounts.

When a person dies from unknown causes, it is necessary for a forensic science professional to do a substance test, to find out which substance reacted in the victim's glass and caused his death.

What is the annual effective absorbed dose equivalent limit for the general public (frequent exposure)
QveST [7]

The annual effective absorbed dose equivalent limit for the general public is 0.1 rem (1 mSv).

Which natural phenomena will over the next 13,000 years gradually cause the northern hemisphere to experience summer during toda
ANTONII [103]

Answer:

Earth's tilt towards the sun will gradually cause the northern hemisphere to experience summer during today's current winter.

Explanation:

It is expected that over the next 13,000 years, the polar region, particularly the north pole will be tilted gradually towards the sun. At that time, the earth will be in the closest position towards the sun. The tilt would be along the axis and also orbital. Henceforth this both forms of earth's tilt towards the sun, will expose the northern hemisphere to maximum solar radiation, this will cause the region to experience summer during winter's time.

Explain how the epithelium in each of the following regions of the respiratory tract is adapted so its structure follows its fun
vovangra [49]

Explanation:

a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>

b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>

c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>
