When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)

mitochondrion

cell membrane

cytoplasm

cell wall

Answers

Answer:

- cell wall -

Explanation:

The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.

So tell yourself does, an animal that already has a skeleton, need the cell wall?!

NO! It dan't! That's why animals don't have the cell walls and plants do.

!!! Hoped that helped !!!

When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.

What is cell wall?

A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.

It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.

The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.

It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.

The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.

Thus, the correct option is D.

The dependant variable is an abbrasive species of fish becoming overpopulated and killing all the fish that help the coral grow causing the coral to die.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?​

Answers

Answer:

Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins

Answer:

(A) Birds are endothermic and have four-chambered hearts, while reptiles are ectothermic and have three-chambered hearts.

Explanation:

got it right on the test

Birds and reptiles both belong to the animal kingdom. Reptiles are ectothermic and have three-chambered hearts, whereas birds are endothermic and have four-chambered hearts. Thus, option A is correct.

What are the characteristics of birds and reptiles?

Birds and reptiles both belong to the kingdom Animalia and are chordates. They both have vertebral columns and the presence of the backbone. They share many similarities and differences in their physical appearances.

The birds are endothermic and can maintain constant body tempearture regardless of the external environment. While reptiles are ectothermic (cold-blooded) and regulate their temperature based on the external environment.

The birds have four-chambered hearts like mammals that separate the oxygenated from the de-oxygenated blood, whereas the reptiles have three-chambered hearts with one ventricle and two atria.

Therefore, the birds are endothermic, and reptiles are ectothermic.

Which table shows two steps of DNA replication?

Explanation: because that’s how it is reached by my teacher I don’t really know how to explain it

DNA replication is a process where the polymerase enzyme adds complementary nucleotide bases in the parent DNA strand, hence option h polymerase matches adenine to thymine is correct.

What is DNA replication?

The process by which a double-stranded DNA molecule is duplicated to form two identical DNA molecules is known as DNA replication.

Replication is necessary because when a cell splits, the two new daughter cells must have the same genetic information, or DNA, as the parent cell. In vitro DNA replication (DNA amplification) is also possible (artificially, outside a cell).

To begin DNA synthesis at known sequences in a template DNA molecule, DNA polymerases isolated from cells and artificial DNA primers can be utilized.

Therefore complementary base pairing of nucleotide base pairing, hence option h is correct.
