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.

Which of the following occurs when a cell repairs a double-strand DNA break by the process of nonhomologous end joining? 1.The D
victus00 [196]

Answer:

option 3

Explanation:

In non-homologous end joining, the break ends are directly ligated together without the need for a homologous template unlike the homologous repair. this form of repair uses short homologous sequences of DNA termed microhomologies to direct repair and these microhomologies are seen as single-stranded overhangs found on the ends of double-strand breaks. When the overhangs are perfectly compatible, NHEJ ligates and repair the break. When these overhangs are not compatible, imprecise repair leading to deletion of nucleotides can also occur which is much more common .

Compare the potiential energy stored in lipids proteins and carbohydrates​
yarga [219]

Answer:

The amount of lipids stored as an energy reserve far exceeds the energy stored as glycogen since the human body is simply not capable of storing as much glycogen compared to lipids. Lipids yield 9 kcal of energy per gram while carbohydrates and proteins yield only 4 kcal of energy per gram.

vaieri [72.5K]
<span>Chlorofluorocarbons (CFCs) chemicals contain carbon, chlorine and fluorine and is t so expensive at the same time it’s not flammable, the reason why it is mainly used in business such as refrigerators and plastics. However, these chemicals destroys our stratosphere, the second layer of the Earth’s atmosphere and protects us by blocking the ultraviolet radiation (UV Light). This type of radiation can seep through organisms skins and can leave destructive effects on DNA molecules which will also cause skin cancer.</span>

Describe the difference in Iguana population size before and after El Niño?
tresset_1 [31]

the population goes down

Explanation:

Large algal beds die, depriving marine iguanas, turtles and many fish of their staple diet. Once weakened, strong swells and sea urchins break apart complex coral habitats that sustain diverse species changing the environment.
