HELP WORTHA FREE BRAINLY IF RIGHT
zalisa [80]

Answer: The answers seem correct.

1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.

2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.

3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.
kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4)  tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

Explain how the structure of epithelium and the structure of connective tissue, specifically bone, relate to the function of the
Aneli [31]
<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.
