What cell parts are common to all of these cells? Use complete sentences.

Natalka [10]

Answer:

between an animal cell and a plant cell there are some parts that are similar and carry out the same function like:

both have a cell membrane which selects what goes in the cell.

both have cytoplasm which holds the protoplasm(the living part of the cell)

both have a nucleus which carries out all cell activities and holds threads of DNA called chromosomes

both have a mitochondria which is the power house of the cell

both have golgi bodies which modify and carry proteins from sites of synthesis to sites of reaction

Which three steps describe how an animal obtains and uses energy for growth?

harina [27]

Answer:

Option C. First, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.

Explanation:

When one animal eats another animal, the body of organisms is made of higher molecules such as carbohydrate, protein and lipids. These large molecules are broken down into simpler substances in the stomach such as glucose, amino acid and faty acid. These substances are absorbed by the body and release energy from them.

Simora [160]

Most lipids are nonpolar. This property causes lipids to be water-insoluble in the bloodstream. Lipoproteins form water-soluble complexes for transport through the bloodstream by surrounding nonpolar lipids with polar phospholipids and proteins .

A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.

These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.

Why do you think scientists track the genes of other organisms such as rats or mice in the database? Do you think rat genes are

DENIUS [597]

Explanation:

Understanding through into genetic risk factors for various illnesses in the human population come from mouse research. Manipulation of the mouse genome is quite simple, for example, adding or deleting genes to better understand their function in the body.

The majority of mice and rats used throughout medical studies are inbred, which means they are genetically virtually similar, making the outcomes of medical trials more consistent.
