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.
Think of another common object around your house or school that you could use to model a cell. Describe the object. Based on its characteristics, does the object best model an animal cell, a plant cell, or a bacteria cell? Why?
Answer:
Out of all the objects I found I think a car represents a cell the best.
Explanation:
The structure a cars body provides makes it comparable to a cell wall and the car's metal body is also represents a cell wall because it maintains its shape even when it travels at high speeds. The windshield and windows can be compared to plasma membranes, since they protect the inside of the car from invaders (like insects). The gas tank represents the vacuole because it holds the energy source for the car, and the engine represents the mitochondria because it is the power house of the car

Which cell type undergoes terminal differentiation?
Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.
What is terminal differentiation?As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.
During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

Diabetes is a disease where the body is unable to produce enough insulin in the pancreas to help lower the levels of blood glucose. The ribosomes manufacturer the insulin in healthy cells, but those who are diabetic do not have healthy cells to do this. In which organ would you find the ribosomes producing insulin in a non diabetic individual?
A.) liver
B.) pancreas
C.) stomach
D.) thyroid
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.
What do you mean by Diabetes?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.

After the amino acid chain leaves the ribosome, which organelle then folds, modifies, and transports the protein?
O Lysosome
O Cytoplasm
O Endoplasmic Reticulum
O Ribosome
Answer:
The endoplasmic reticulum
Explanation:
It is not the lysosome because their processes are degrading and recycling cellular waste, and involved in energy metabolism
It is not the cytoplasm because the cytoplasm doesn't do anything itself, it just provides an environment for the rest of the organelles to do their job
It is not the ribosome because the amino acid chain left the ribosome in the question
For secretory, plasma membrane, and organelle proteins, the endoplasmic reticulum (ER) is a significant protein folding compartment. Thus, option C is correct.
What is the role of Endoplasmic Reticulum in folding?A polypeptide chain cannot acquire its right structure and function without protein folding.
Chaperones are HSP that aid in protein folding. Chaperonins are multimeric complexes that fold proteins by forming hollow structures.
Numerous general activities of the endoplasmic reticulum include transporting produced proteins in vesicles to the Golgi apparatus and folding protein molecules into sacs termed cisternae.
Therefore, Endoplasmic Reticulum folds, modifies, and transports the protein.
