Identify a structure other than a cell wall or a vacuole that might be found in a plant cell but not in an animal cell. explain
enot [183]
One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.

Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.

Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.

Which cell components are responsible for giving the cell its shape and support?
IgorLugansk [536]

Answer: Cytoskeleton and cytoplasm

The cytoskeleton is a network of microfilaments that provide structure and support for the cell. You can think of them as the pillars/columns that hold up a house.

The cytoplasm is the aqueous fluid that fills the inside of the cell. This fluid is very important for giving a cell is shape/support. If the cytoplasm was drained out of a cell its shape would collapse like a water balloon losing its water.

Access Control Points

They are restrictions points that enforce regulations and guidelines on decontamination when exiting the sites and ensuring adherence safety standards when entering the site. The regulation are usually, as standard practice, conspicuously posted at the Access Control Points.
Access Control Points are usually set up at the periphery of the Exclusion Zones, and ideally, there should be a separate entrance and exit Control Access Point.

Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these obs
Drupady [299]

Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.

One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.

The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.

Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.
