Answer:
The cell has to undergo a process called Osmosis
Cell performs diffusion and osmosis to move substances from an area of low concentration to an area with high concentration through the semi-permeable membrane.
What is Cell transport?
Cellular transport is the mechanism through which substances move from a region of low concentration to a region of high concentration. Cellular transport takes place through osmosis and diffusion.
In osmosis and diffusion, the particles such as water and ions move due to concentration gradient from a region of high concentration to the region of low concentration of particles through the cell membrane. The membrane allows the movement of non-polar substances through membrane however some particles are unable to cross the membrane and thus requires transport proteins which facilitates their movement.

Convergent plate boundaries can form which of the following?
Rift Valleys
Deep Ocean Trenches
Mountains
Volcanic Island Arcs
New Ocean Floor
Answer:
Deep Ocean Trenches, Volcanic Island Arcs and mountains
Explanation:
At a convergent plate boundary two plates collides with one another. Based on the type of plate, different features can form at such a margin.
In a continental - continental crust collision, both plates have the same density so, they build up on collision to form a mountain. In an oceanic - continental crust convergence; the oceanic plate is denser and it subducts. This leads to the formation of trenches. Also, here, the subducted plate will melt and a crack within the crust can allow for the melt to reach the surface and solidify to form volcanic Island arcs. Oceanic - oceanic crust convergence is also known.1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older
Answer:
Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.

Summarize the 3 types of cell division: Binary fission, mitosis, and meiosis
Answer:
Binary Fission is the reproduction of prokaryotic cells (bacteria and bacteria-like Archaea) is accomplished through binary fission. Binary fission is essentially cloning. Barring mutations that may have occurred when the genetic material was copied (a process called replication), the two resulting daughter cells are identical to the parent cell.
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

Explanation:
In your own words describe how genetic diversity is increased through the processes of crossing over, independent assortment, and random sexual reproduction.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

Which of the following best explains how insulin injections affect signal transduction in an individual with type 1 diabetes
A. They serve as second messengers to regulate glucose uptake to cells
B. They allow alternate signaling transduction pathways to control glucose levels
C. They open channels to allow signaling molecules to enter pancreatic cells
D. They provide a signaling molecule to begin the signal transduction pathway
Answer:
The correct answer is - option A. They serve as second messengers to regulate glucose uptake to cells.
Explanation:
Type one diabetes is a condition that is characterized as the inability to produce enough quantity or at all of the insulin by the beta cells of the pancreas. Therefore, a patient with this condition completely depends on exogenous insulin to maintain the sugar level in the blood.
Insulin is the hormone that removes the excess amount of glucose from the blood by the adipose tissue, liver cells, and skeletal muscle that uptake an extra amount of sugar. there are receptors present on the surface of the plasma membrane which binds with the insulin and acts as a secondary to regulate a cascade reaction to glucose uptake to cells.

Answer:

Explanation:
A lake in Minnesota was thriving with black bass and bluegill. These particular fish build nests on the sandy bottom of the lake. Now, ecologists are finding that over time a layer of humus has slowly been covering the pond. The ecologists are noting that the populations of black bass and bluegill are declining, and the fish that are able to make nests in humus are rising in numbers.
The ecologists can probably conclude that this event is an example of:
commensalism
parasitism
primary succession
succession
Answer:
Explanation:
https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession
The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.
Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.
In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.
The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.
The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.
Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.
