Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.

Biotic factors - The living components or the living things that are present in the ecosystem that shapes the environment are known as biotic factors. Examples are plants, bacteria, algae, birds, fishes etc.

A ecosystem runs through the interaction of biotic and abiotic component.  Biotic supplements acts as a fuel that supports the bacterial growth.

Periwinkle snails graze on the top of the cordgrasses to escape from their predators blue crab. They graze on the fungi and algae that is inhabitant on top of the grass, they do not feed directly on the cordgrass

While grazing they actually damage the cordgrass by spreading the fungal infection.

Hence, option B is Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails is correct.

The correct question is :

One of the most common plants in Atlantic salt marshes is cordgrass. Periwinkle snails cling to the top of tall cordgrasses during high tide. The tall cordgrasses provide protection from the snails’ predators, such as the blue crab. While the snails do not feed directly on the cordgrass, the snails can damage the cordgrass when they graze on algae and fungi that grow on the grasses. If the snail population grows too large, it can decrease cordgrass growth.

Question

Based on the passage, which of the following describes the ecological role that cordgrass serves for the snails?

Responses

A. Cordgrass is a biotic factor for the snails because it is the snails’ main food source.

B. Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails.

C. Cordgrass is an abiotic factor for the snails because it provides habitat for the snails and crabs.

D. Cordgrass is an abiotic factor for the snails because it produces algae and fungi for the snails.

Explanation:

LOTS of animals eat beavers like A LOT and i would think that something would eat it before the wolf

Answer:

Beaver is out of place in the food chain

because-

Beaver is an animal and is a heterotroph and cannot use sunlight to make it's food but while plants can.

correct order would be-

sunlight - cattails - beaver - wolf

Active transport occurs against the electrochemical gradient. It needs energy to move molecules from the lower concentration side to the higher concentration side. The mode of transport is active transport.

-------------------------------------------------

There are three main different types of transport across the membrane

Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen.

Molecules move from the lower concentration side to the higher concentration side of the membrane.

Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential.

In the exposed example, a scientist wants to determine how substance L enters a cells in a culture.

Table 1. Rate of entry of substance L into mammalian cells in culture

External concentration of substance(mM)      Rate of entry of substance L

                     10                                                                     5%

                     20                                                                    25%

                     30                                                                    45%

                     40                                                                    65%

                     50                                                                     80%

                     60                                                                     90%

                     70                                                                      95%

                      80                                                                    100%

                      90                                                                    100%

                      100                                                                   100%

Now, we need to identify the most likely mode of transport across the membrane for substance L, and explain how information provided helps determine the most likely mode of transport.

We know that the intracellular concentration is 120mM.

As we can see, this concentration exceeds all of the culture media concentrations. Yet, the substance keep moving into the cell.

As the concentration inside the cell is always higher than the concentration outside, we can assume that this is not passive transport because the molecule transport is going against its concentration gradient.

Hence, the remaining option is active transport. And as said before, we can see it because the substance keeps crossing the membrane toward the cell interior despite its concentration being higher in the interior of the cell than in the exterior.

Explanation:food, water, habitat, and mate.

Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.

The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.

• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.

• Biotic factors are all the living components in the ecosystem.

Biotic and abiotic factors influence the survival and reproduction of living beings.

Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.

These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.

Limiting factors might be a result of the population density or might be dense-independent.

When talking about dense-independent limiting factors we are referring to

When talking about dense-dependent limiting factors we are referring to biotic factors and the interactions established between species that control other species' growth.

These are, for instance,

Each species carries out a different role in these interactions.

These relationships and the results are what determine the destiny of the populations and their size.

Now, since I do not have the text, I will suggest a few examples of limiting factors. Take a look at them and then look for some other examples in your reading.

Limiting abiotic factors:

Following this framework, you should look in your reading which limiting factors are described.

insulin is produced in the pancreas

The pancreas is the organ in which ribosomes produce insulin in a non-diabetic individual. So, the correct option is B.

Diabetes may be defined as a disease that increases the blood glucose level as compared to normal. This is due to the body being unable to produce enough insulin in the pancreas to help lower the levels of blood glucose.

Insulin is produced in the pancreas with the help of ribosomes in non-diabetic individuals.

Therefore, the organ in which ribosomes produce insulin in a non-diabetic individual is the pancreas.

Answer:

the most durable and tough substance in your body is actually a tissue. Encasing your teeth and helping you chew, bite, and tear your food is your tooth enamel. That's the hardest substance in the human body.

Explanation:

The most durable part of the human body is Tooth Enamel.

Tooth enamel is defined as the thin outer covering of the tooth that covers the crown of the tooth. This is the part that we can see outside the gums. This is the outer layer, the enamel is transparent. Dentin is the hard tissue that lies beneath the enamel, and is what gives teeth their color.

Once tooth enamel is damaged, it cannot be restored. Enamel can be restored to some extent by improving its mineral content. Enamel is the durable part of the human body.

While toothpaste and mouthwash can never "rebuild" teeth, they can contribute to this remineralization process.

Thus, the most durable part of the human body is Tooth Enamel.
