Answer:
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.
What is the function of Aquaporin?The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.
Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.
If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.
Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

-Calculate the fluid pressure at Piston A.
-Calculate the force exerted on Piston B.
-Which principle is being applied? What does the principle state?
Show all your work!
Answer:
80N
Explanation:
in both sides, pressure is the alwyays the same whatever the area is..
First we calculate the pressure at piston A:
P= F÷a
given that,
#F= 20N
#a=1m^2
P= 20÷1
P= 20 Pa.
At piston B:
pressure is the same = 20Pa
Area= 4m^2
P=F/a
F= P×a
F= 20 × 4
F= 80N
It takes place when magma introduces
great amount of heat into an existing rock
resulting in the recrystallization and mineral
reaction in the rock.
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.

A sequence of nucleotides in a DNA or RNA molecular is What?
Answer:
nucleic acid sequence
Explanation:
Which statement best describes the function of nucleic acids?
A. Stores genetic information and helps to make proteins
B. Increases the rate of chemical reactions
C. Stimulates metabolism in all body cells
D
Activates secretion of the body's hormones
Answer:
A. stores genetic info and helps make proteins.
Explanation:
Nucleic acids are DNA and RNA.
The statement that best describes the function of nucleic acid is stored genetic information and helps to make proteins. The correct option is A.
What is nucleic acid?Nucleic acid is a macromolecule. Nucleic acid is made up of nucleotides. The composition of nucleotides is a 5-carbon sugar, a phosphate group, and a nitrogenous base.
Nucleic acid is the main component of the genetic material of the living organism. They are DNA and RNA. DNA is the main genetic material of animals and plants, and RNA is found in some bacteria and some plants.
DNA and RNA store the genetic information of the organism. As this, nucleic acid also contains genetic material. This genetic information is used in synthesizing proteins.
Thus, the correct option is A. Stores genetic information and helps to make proteins.

What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

Is better for an ecosystem to have high or low species abundance?
Answer:
There should equilibrium state in the ecosystem in case of number of species, if there will be high species abundance there would be higher rate of competition in between the species also the predation can be easily seen in such ecosystem. On the other hand if the species abundance is low then the competition between the species and predation can not be seen.which statement correctly describes the relation skip between genes, proteins, and traits?

Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid. Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below. Which organism is the least plentiful in the pond water studied? A. amoeba B. volvox C. euglena D. paramecium
Answer:
Euglena
Explanation:
the least plentiful organism in the pond water studied. Each student found fewer euglena than any other organism.
Why is the intensity of a pulse different at different sites?
Answer:
Because pulse wave velocity decreases as arterial diameter decreases, a slight difference in local vasculature can cause inter-site differences not only in pulse transit time but also in its variations.

how are algae cells different from other cells
Answer:
In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.
Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.
Some characteristics of algae cells are:
• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.
By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.
• The cell wall is made up mainly of cellulose and glycoproteins.
• In the algae cells we can find different reserve substances produced by metabolism.
The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.
These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.
• They have structures of locomotion called flagella.
In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.
Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.
