A typical prokaryotic cell has about 3,000 genes in its DNA, while a human cell has about 20,500 genes. About 1,000 of these genes are present in both types of cells. Explain how such different organisms could have this same subset of genes ?

Answers

Answer 1

Answer:

Answer:

same DNA bases and HGT

Explanation:

Even though we are different species, so much as different kingdoms, the DNA is always going to be the molecule that contains our genetic information and constitute our genes. This molecule is made up by the same structure: a sugar, a phosphate and a base like adenine, guanine, cytosine, thymine. Regardless if its a human, bacteria, fungi or a plant cell we all share this in common.

It is well known that we acquire our whole set of genes from our ancestors but some studies have shown that we also acquire genes from other organisms and its called horizontal gene transfer (HGT). HGT involves the movement of genetic material between different species. Since we've been sharing the world with a lot of prokaryotic organisms we might have experienced the HGT at some point of the evolution, and since our genetic material is made up of the same molecules, we can have the same subsets of genes working in both organisms.

Answer 2

Answer:

Answer:

The subset of genes shared by humans and prokaryotes originates from a common ancestor and has been retained over billions of years of evolution.

What constitutes the majority of the debris found in the “garbage patch” located in the North Pacific Ocean?

Answers

Answer: plastic is the main constituent in the garbage patch found in North Pacific Ocean. It was estimated to be approximately 80 thousand tonnes or about 1.8 trillion pieces of plastic in the patch. A total of 1.8 trillion plastic pieces were estimated to be floating in the patch.

Plastic is most of the debris.

Free-floating fishing nets make up another 10 percent of all marine litter, or about 705,000 tons, according to U.N. estimates.

Adipose tissues belong to ___________a. nervous tissues
b. muscle tissues
c. connective tissues
d. epithelial tissues

Answers

Answer:

c. connective tissues

Explanation:

Adipose tissue is a connective tissue which is composed of cells called adipocytes. Since it a loose connective tissue located beneath the skin and around internal organs.

The main function of this tissue is to store fat, although it also cushions and insulates the body. It provides protective covering around internal organs. Since it stores fat it also functions as a reserve of nutrients.

Adipose tissue also acts as an endocrine organ. It has the ability to make a number of biologically active compounds that regulate metabolic homeostasis.
