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 do not have genetic material nor can they reproduce. No, viruses are not alive because they do not have genetic material nor can they reproduce. No, viruses are not alive because they rely on a host organism to be able to reproduce.

The correct response is: No, viruses are not alive because they rely on a host organism to be able to reproduce.

While it is true that viruses contain genetic material and can reproduce, they cannot do so independently. They need to infect a host cell and hijack that cell's machinery to replicate themselves, which is a key reason why they are typically not considered to be alive by most definitions of life.

Of the five characteristics of living things, which one is required for the species to survive but does not have to apply to an individual?(1 point) Responses reproduction reproduction response to the environment response to the environment use of energy to function use of energy to function growth and change over a life cycle

The correct response is: reproduction.

Reproduction is a characteristic required for a species' survival because it enables the continuation of the species over generations, but an individual organism does not need to reproduce in its lifetime for the species to survive.

Plant cells can use energy from the sun to make food. Animal cells cannot. Which organelle is responsible for this difference between plant and animal cells?(1 point) Responses plasma membrane plasma membrane cell wall cell wall chloroplast chloroplast central vacuole

The correct response is: chloroplast.

Chloroplasts are the organelles in plant cells that allow them to capture energy from sunlight and use it to produce food through the process of photosynthesis. Animal cells do not have chloroplasts, which is why they cannot make their own food using sunlight.

Which statement about plasma membranes is correct?(1 point) Responses Animal cells have cell membranes instead of plasma membranes, Animal cells have cell membranes instead of plasma membranes, Both plant cells and animal cells have flexible plasma membranes. Both plant cells and animal cells have flexible plasma membranes. Plant cells have rigid plasma membranes. Plant cells have rigid plasma membranes. Plant cells have cell walls instead of plasma membranes.

The correct response is: Both plant cells and animal cells have flexible plasma membranes.

Both plant and animal cells have plasma membranes (also known as cell membranes) that are flexible. While plant cells also have a rigid cell wall outside the plasma membrane, this does not make the plasma membrane itself rigid.

Which organelle processes sugar?(1 point) Responses central vacuole central vacuole endoplasmic reticulum endoplasmic reticulum mitochondrion mitochondrion nucleus

The correct response is: mitochondrion.

Mitochondria are the organelles responsible for processing sugar (and other nutrients) to produce energy in the form of ATP through cellular respiration. While the endoplasmic reticulum is involved in the synthesis and processing of proteins and lipids, the mitochondrion specifically processes sugars for energy conversion.

What is the function of the plasma membrane? (1 point) Responses It helps filter waste inside the cell. It helps filter waste inside the cell. It helps plants maintain their shape. It helps plants maintain their shape. It contains hereditary material. It contains hereditary material. It helps recognize other cells. It helps recognize other cells.

The correct response is: It helps recognize other cells.

While the plasma membrane has several functions, including acting as a barrier and facilitating communication between cells, its role in recognizing other cells is one of the key functions, particularly through the use of proteins and carbohydrates on its surface that serve as signals for cell recognition and interaction.
