3 0

Complete Question: Which sentence supports the statement that complex, multicellular organisms are made up of specialized cells that each perform different functions for the body?

A. Human liver cells make proteins that promote homeostasis that neurons do not.

B. Different species of bacteria have different shapes and structures to their cells.

C. The DNA in the cell nucleus of chimpanzees and humans are 98% identical.

D. Prokaryotes do not have nuclei, but they can still carry out the basic functions of life.

Answer:

A. Human liver cells make proteins that promote homeostasis that neurons do not.

Complex multicellular organisms are made up of different cells which are combined to form the non-identical organs and tissues e.g (heart, liver etc.) .These organs carry out totally different function for the sustenance of organism.

Explain the relationship among

Iteru [2.4K]

Answer:

There is an important relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.

Explanation:

There is a great relationship among homeostasis, defective mitochondria and the symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.

juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025

Describe the steps in making packaging and exporting a protein from a cell

irina [24]

Answer:

The steps in making packaging and exporting a protein from a cell are listed below in the following points:

Protein is made from the Ribosomes.

These proteins are gathered in the endoplasmic reticulum.

From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.

The Golgi bodies modify the protein to suitable forms that can be absorbed.

Finally it is transported to all part of cells in our body.

Which of the following statements gives the most fundamental reason why ornithine is unlikely to be found in proteins synthesize

BlackZzzverrR [31]

Answer:

option A

Explanation:

ornithine is a non-protein and non-essential amino acid it is formed in plant by L-glutamate and in animals it is formed during the urea cycle by the catalyzation of arginine which is an enzyme. In vivo ornithine is not found in protein synthesis because it do not have any codon so it can not endoded by DNA but can be synthesized.

Ornithine is a precursor of glutamic acid, proline amino acid and citrulline amino acid
