Well it couldnt be an animal cell becuase animal cells dont have cell walls. And plant cells have a cell membrane not a plasma membrane so it should be a prokaryotic cell.

Answer: Prokaryotic cell

Explanation:

An organism that has plasma membrane, cell wall and ribosomes states that it is a prokaryotic cell.

All the prokaryotes have thick and rigid cell wall that provides the cell its shape and structural support.

Ribosomes are found in prokaryotes as well as eukaryotes. Cell wall of prokaryotes is made of peptidoglycan layer which surrounds the cytoplasm of the cell.

As it has similar characteristics to a prokaryotic cell it is a prokaryotic cell.

3. What is the difference between the environmental impacts of particles, such as dust and
Minchanka [31]

Answer:

Environmental impacts of particles, such as dust and  smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem

Environmental impacts of greenhouse gases released from livestock  production - increase in atmospheric temperature

Explanation:

Environmental impacts of particles, such as dust and  smoke, released from livestock production -

Release of particles such as  dust and  smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.

These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.

Environmental impacts of greenhouse gases released from livestock  production -

Green house gases will lead to increase in atmospheric temperature

The antiparallel arrangement within DNA molecules refers to Select one:
mylen [45]

Answer:

c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.

Explanation:

A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>

I annexed an image of the DNA structure.

I hope you find this information useful and interesting! Good luck!

Identify the stages of mitosis .
Alexxandr [17]

Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase. Each stage of mitosis is necessary for cell replication and division.

What shared characteristic can be written at point X? Use complete sentences to explain your answer.
solong [7]

Answer:

Multicellular

Eukaryotic

Heterotrophs

Explanation:

Both cells of fungi and animals are eukaryotic meaning they have  nucleus and organelles. They are multicellular organisms (meaning they are composed of many cells). Their cells are also heterotrophic meaning they depend on organic molecules for energy as opposed to plants that can make their food from abiotic factors. Fungi, however, digest their molecules extracellularly while animals do it intracellularly.
