Answer:
RNA interference
Explanation:
The RNA interference (RNAi) pathway is a naturally occurring mechanism in which regulatory non-coding RNAs (ncRNAs) suppress gene expression by targeting messenger RNAs (mRNAs). The RNAi technique is used in molecular biology laboratories and biotechnology applications to reduce the expression of target genes by delivering small interfering RNA (siRNA) molecules targeting a gene of interest. These siRNAs are artificially synthesized to bind by complementarity to the target mRNAs, thereby they can be used for transient gene silencing. This technique does not require genetic modification of the cells, since RNAi can be achieved by direct exogenous delivery of siRNAs.

Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Group of answer choices
It converts a polymer to its monomer subunits.
It moves substances across the plasma membrane.
It accelerates the production of a second messenger.
It transfers phosphate groups from to protein substrates.
Answer:
It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.

Second and third class levers both have __________.
A.
the fulcrum between the effort and load
B.
effort applied in the same place
C.
two loads and fulcrums
D.
the fulcrum at one end of the lever
Levers of the second and third classes both have their fulcrums at one end. Therefore, option (D) is correct.
A third class lever places the effort between the fulcrum and the load, while a second class lever places the load between the fulcrum and the effort. The benefit of having the load closer to the fulcrum, which results in an enhanced mechanical advantage, is what distinguishes second class levers.
This enables more force to be applied to the load with less effort. Third class levers, on the other hand, present a mechanical disadvantage in terms of force but have the advantage of a longer effort arm, permitting higher speed and range of motion.

CAN YOU PLEASE HELP! This boulder is found in Wales in an area that was once covered by a glacier. When the glacier retreated it left the boulder behind. which process directly resulted in this boarder being left behind? A. Mass wasting. B. Erosion. C. Weathering. D. Deposition
Answer:
C
Explanation:
The process that directly resulted in this boulder being left behind is deposition. Therefore, the correct statement is option D.
What is deposition?Deposition is the process of laying down sediment carried by wind, water, or ice. Deposition is the geological process where sediments, soil, and rocks are added to a landmass due to erosion and cause sediments they were carrying to be deposited in a new location. Glaciers are large masses of ice that move slowly over the land, carrying rocks and sediments with them.
Glaciers melt and deposit the sediments they were carrying when they retreat. The glacier are carrying the boulder along with it while moving, and when it melted, the glacier left the boulder behind.
Mass wasting, erosion, and weathering lead to the breakdown of rocks and sediments, but these processes do not cause deposition of rocks or sediments in a particular area.
Therefore, the process that directly resulted in this boulder being left behind is deposition.

A rabbits niche is as an important grazers, maintaining some important grassland habitats, if a catastrophe were to reduce rabbit population numbers, what would happen???
A- important grassland butterflies would be lost
B- There would be more grass for the surviving rabbits
C- The grassland would be invaded by trees and shrubs
D- all of the above
Can anyone help me with this question!!
If your correct i will give you the extra points!!
Answer:
The correct answer is - option B. There would be more grass for the surviving rabbits
Explanation:
As we know and given that the rabbits are the important grazers that help in maintaining the grassland habitats. If there would be no catastrophe to lower the population of the rabbit population then there will be overgrazing and there would be no grass for the rabbits.
But as it is given that there is a catastrophe that was to reduce the rabbit population then there will be a limited number of rabbits so there will be no overgrazing and there will be enough grass for the surviving rabbits.
The option that will occur if a catastrophe were to reduce rabbit population numbers will be D. All of the above.
A niche simply means the role that's played by an organism in the community.
It should be noted that in a situation where there's a reduction in the rabbit population, there would be more grass for the surviving rabbits
Also, since there are lesser rabbits, the grassland would be invaded by trees and shrubs.
In conclusion, the correct option is All of the above.

Solar energy is used to produce energy-rich compounds in which structure?
A.A
B.B
C.C
D.D
Answer: A or which ever is the chloroplast
Explanation:
Chloroplast is the site for photosynthesis in plants. Thus, option A is correct.
What are chloroplasts?Chloroplasts are the cell organelles present in the plants. Chloroplasts are one such type of plastids.
Chloroplasts are green in colour. They contain a green coloured pigment called chlorophyll which traps the solar energy.
The solar energy is converted into chemical energy by a process called photosynthesis. The organic molecules so produced are the energy rich compounds.
Chloroplasts are chiefly found in the mesophyll region of the leaves.
Chloroplast consists of grana and stroma regions. The grana contain disc shaped coin like structures called thylakoids. The matrix of chloroplasts constitutes stroma region.
Various enzymes, DNA, ribosomes etc are found within the chloroplasts. Hence, they are also referred as 'cell within the cell'.
Chloroplasts have unique feature of self-replication. Chloroplasts are similar in function to mitochondria in animal cells.
Therefore, chloroplasts are important plant structures for photosynthesis.

Q1.22. A higher population density, faster transmission rate, and
longer infectious period each cause a disease like influenza to
spread to more people. Which of the following statements
correctly explain why?
Check all that apply:
At high densities, infected individuals encounter more individuals
who are also infected.
At high transmission rates, an infected-susceptible encounter is
more likely to result in an infection.
With long recovery, an infected individual is contagious longer and
can infect more susceptibles.
A) When the densities are high as a result of overcrowding,lack of sanitation exists and this will further lead to breeding ground for organisms that are responsible for causing disease that is causative agents for transmission that is environmentally mediated,as a result, infected individuals encounter more infected individuals.
B) Individuals that are infected and that are also susceptible have immune system that is weak than others hence when transmission is high,they tend not to get infected.
C) Yes,I will infer that provided that the individual that is infected us cured completely, however,the pathogen still exists within the system and can as such infect more susceptible individuals.
Rigor mortis occurs after a person dies because muscle cells are no longer supplied with ATP. This causes the muscles to become rigid and stuck in position. Based on your knowledge of muscle contraction, why would muscles become rigid, rather than limp, after death
Answer:
When they stop receiving energy in the form of ATP, the muscle fibers and sarcomeros stagnate in one position and hypertrophy, that is why sometimes post-mortem facial expressions are very noticeable since the facial muscle was not relaxed. .
On the other hand, it is not only the energy source that stops being supplied due to systemic failure but also due to the accumulation of gaseous collection by decomposition that makes movements impossible and stagnates the joints and muscular structures.
Explanation:
Rigor mortis is an irreversible systematic tetanization that occurs in all the dead, there are no exceptions.
