Question

A student claims that viruses are alive because they have genetic material and can reproduce. Is this student’s claim correct?(1 point)
Responses

No, viruses are not alive because they rely on a host organism to be able to reproduce.

Chloroplasts play an important role in energy production in plant cells. However, some parts of a plant, like the roots, lack chloroplasts. In one to two sentences, explain the most likely pathway for root cells to obtain energy, and identify the organelles involved

Root cells obtain energy through the process of cellular respiration, which takes place in the mitochondria. They break down glucose molecules to release energy.

In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.

Animal cells do not require a cell wall because they obtain their shape and support exclusively from their cytoskeleton. Additionally, animal cells do not experience the turgor pressure fluctuations that plants do, so it is not necessary for them to have a cell wall to maintain their shape and protect against damage due to swelling and collapsing. Centrally located vacuoles in eukaryotic cells are not essential for animal cells as they don't contain as much water as plant cells do and therefore animal cells do not require them to regulate their internal fluid balance.

I apologize, I assumed you were asking me to respond to a question. Could you please provide me with a question or a prompt so I may assist you better?

In three sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.

Animal cells generally maintain their shape through the cytoskeleton and rely on intercellular junctions to form tissues. Furthermore, animal cells do not have large central vacuoles owing to which they do not require them to store nutrients, regulate inner cellular pressure or protect against predators. Lastly, animal cells do not have cell walls as it would prevent their ability to engulf food and thus would hinder their feeding ability.

In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .

Amoebas and mice digest their food through different mechanisms. Single-celled amoebas rely on phagocytosis, where food is engulfed into the cell, broken down by enzymes and absorbed into the cytoplasm. In contrast, in multicellular organisms such as mice, food is mechanically broken down by teeth and chemically digested in the stomach by enzymes. Absorbed nutrients are transported to the liver for processing and delivery to other cells through circulation.

In three sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .

In amoebas, food digestion is facilitated by the process of phagocytosis where food is engulfed and digested intracellularly. In mice, food digestion is accomplished by mechanical and chemical digestion starting from the mouth, stomach and intestine with different types of enzymes. Absorbed products are then processed and transported by blood circulation.
