ELEN [110]3 years ago
7 0
The reason as for why the atmosphere exerts a force or pressure, force over a given area, is because of the particles of Gases within the air, oxygen, carbon dioxide, nitrogen etc, all constitutes air, and the weight of air is ultimately what exerts pressure.

The solution is A. Because of the weight of air.

Which choice best describes the antimicrobial activities in the mouth?
kykrilka [37]

The antimicrobial activities in the mouth are hydrochloric acid denatures proteins and killing many microbes.

The capability of an hydrochloric acid activating pathogen-killing compounds is not a part of insect immunity,There has recently been an increase in interest in trehalose metabolism for therapeutic applications due to trehalose's relevance in numerous pathogenic species.The most significant biosynthetic process is the enzyme TPP (trehalose-6-phosphate phosphatase) (OtsAB).

Here, five important nematode and bacterial pathogens' recombinant TPPs, including three new members of this protein family, are compared for their enzyme characteristics.

The kinetics of the hydrolysis of trehalose-6-phosphate show that all five enzymes display burst-like kinetic behaviour, which is characterised by a decrease in enzymatic rate beyond the pre-steady state.

The observed super-stoichiometric burst amplitudes can be explained by many global conformational changes that occur in members of this enzyme family during substrate processing.

The drop in carbon dioxide in your blood that occurs when you hyperventilate is called hypocapnia. It signals a breakdown in the
daser333 [38]

Answer:

Blood cells

Explanation:

Hypocapnia refers to a situation whereby carbon dioxide is at a reduced level in the blood. This phenomenon is usually caused by deep/rapid breathing known as hyperventilation.

It signals a breakdown in the exchange of gases inside your blood cells where the stuff your body doesn’t want is swapped out for the stuff it desperately needs.

If all living things are related then where did all their differences come from?
stiks02 [169]

Answer:

<em>Hox </em>Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.

Hope that answered your question!

Rudiy27
<span>When you are pregnant, you do not ovulate because you have already fertilized an egg and it is embedded into the uterus where it is growing into a baby. The body knows this, so it does not shed the uterine lining. The shedding of this lining is triggered by hormones which change when the body is pregnant. During pregnancy, a large amount of progesterone is initially produced which helps to prevent the lining from shedding. If you are not pregnant, your progesterone level will begin to decline at the end of your cycle, triggering the shedding of the lining and the period. Birth control pills alter your hormones to mimic a pregnant state. This will prevent the body from releasing an egg and then shedding the uterine lining.</span>
