garik1379 [7]3 years ago
8 0

Answer:

false

Explanation:

Fire extinguishers, emergency showers and eye wash stations are basic safety elements that must be present in all laboratories, regardless of their classification. This is because these are essential elements for common accidents in laboratories and can be easily solved with their presence.

the Effects of Branchial Chloride Cell Proliferation on Respiratory Function in the Rainbow Trout Oncorhynchus Mykiss
gavmur [86]

Thickening of gill epithelia in rainbow trout, caused by chloride cell proliferation, could lead to an impairment of oxygen uptake under moderate to severe hypoxia (Thomas et al 1988; Bindon et al., 1994; Greco et al., 1995).

<h3>What results in an increase in AMS in interstitial lung disease?</h3>

The number of alveolar macrophages (AMs) can rise in interstitial lung disease. Precursor cells from the peripheral circulation may have been drawn in, and/or there may have been local lung growth, to create this.

<h3>What connection does sarcoidosis have between lymphocytes and proliferating cells?</h3>

Additionally, a strong association between the quantities of lymphocytes and proliferative cells in sarcoidosis and fibrosis was discovered in bronchoalveolar lavage (BAL). Eosinophil counts and proliferating cell counts were positively associated in fibrosis.

<h3>How do AMS patients and healthy controls differ in terms of propagating AMS?</h3>

With a substantial association between these two indices, there was a considerable increase in proliferating AMs in all patient groups when compared to healthy controls (4.2 versus 1.4% Feulgen, and 2.1 against 0.5% Ki67).

6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______
Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>

A strand of DNA has the bases AGTAAC. Using letters, show the matching DNA strand.
kkurt [141]
The matching DNA strand would be A - T, G - C, A -T, A - T, C - G, or in other words TCTTG (because you had the strand AGTAAC). 

Always remember that A pairs with T, G pairs with C, T obviously pairs with A, and C obviously with G.

What conclusion can be made if the cell margins of a biopsy are clear when observed under a microscope
Juli2301 [7.4K]

The cancer has not invaded other tissues is the conclusion which can be made if the cell margins of a biopsy are clear when observed under a microscope in this scenario.

<h3>What is Biopsy?</h3>

This medical procedure involves taking sample of cells or tissues from parts of the body and observing it under a microscope.

The microscope function is to enlarge the objects which are positioned on the objective lens thereby making it possible for them to be seen more clearly and accurately.

If the cell margins of a biopsy are clear when observed under a microscope, it means the cancer hasn't invaded other parts while in a scenario where the cell margins are crowded then it depicts the presence of cancerous cells thereby making it the most appropriate choice.

Breathing rate is most likely to increase if the blood level of
trapecia [35]

Answer:

Breathing rate is most likely to increase if the blood level of carbon dioxide increase.

Explanation:

Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.
