Answer:
Aquaporins
Explanation:
Aquaporins are the channel proteins that is present in the membrane of the cell which allow water to cross the membrane very quickly. This aquaporins play an important roles in plant cells, red blood cells, and certain parts of the kidney where this protein minimize the amount of water lost as urine. Without this protein, the diffusion of water across the cell membrane is not possible very quickly.

Which statement best describes how a tree and a mouse get the glucose they need as a source of energy?
O Both a tree and a mouse get glucose indirectly from other living things
A tree makes glucose using the sun's energy, and a mouse gets glucose by eating other living things
Both a tree and a mouse use the sun's energy directly to produce glucose.
Both a tree and a mouse convert ATP into glucose.
Answer:
The correct answer is
A tree makes glucose using the sun's energy, and a mouse gets glucose by eating other living things.
Explanation:
A tree uses photosynthesis to create energy in the form of glucose. On the other hand, a mouse cannot use the sun's energy to produce glucose through photosynthesis. Therefore the mouse must obtain the glucose by consuming other organisms, such as plants and insects.

Write two sentences or clues, one for each word, that will help you remember the difference between actin and myosin. (Example: Actin is actively pulled)?
Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.

Which factor plays a central role in determining which of the brain's synapses will be eliminated and which will be maintained?
Answer:
The answer is "frequency with which they are activated".
Explanation:
Frequency refers to the number of consecutive repetitive events per unit time. It is measured in hertz (Hz), equivalent to a single event per second. The time is the number of one cycle in a recurrent event, and so the duration is the same for the frequency, hence the frequency at which they are triggered is a key determinant of the brain's connections to be eliminated and maintained.
A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Answer: Living Planet Index
Explanation:
The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.
With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.
The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.

1) what are the roles of plants, animals and decomposers in an ecosystem ??
Explanation:
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
Which of the organism doesn't have backbone

Eukaryotic chromosomes contain two general domains that relate to the degree of chromatin condensation. These two regions are _
Answer:
This question lacks options, options are: A) Heterochromatin and euchromatin
B) Uniform in the genetic information they contain
C) Separated by large sketches of repetitive DNA
D) Each void of typical protein-coding sequences of DNA
E) Void of introns.
The correct answer is A.
Explanation:
The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.
Which of the following proteins could be used to carry proteins across the
cell membrane?
Answer:
The answer is B :)
Explanation:
Proteins pass through the membrane through passive transport. So the protein used to carry protein through integrated channel membrane. so the correct option is C.
What are proteins?A protein is a naturally occurring complex substance which consists of amino acid residues joined by peptide bonds.
Passive transport is defined as movement of a solute from a region of high electrochemical potential to a region of lower electrochemical potential on the opposite side in cell membrane. The figure representing the protein transportation through protein carrier channel.

What do stabilizeing selection and disruptive selection have in common
Explanation:
Stabilizing selection is the opposite of disruptive selection. Instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. Stabilizing selection tends to remove the more severe phenotypes, resulting in the reproductive success of the norm or average phenotypes.
