5. What is pretexting? How is this used?

Describe the function of each organelle.

Elis [28]

Answer:

Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles

Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.

Ribosome: A small particle in the cell that can make proteins.

Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.

Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.

Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.

Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)

Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).

Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.

Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.

Two reasons why interdisciplinary science is important to society

Troyanec [42]

The reason why interdisciplinary science is important to society is because of the following reasons; It has incorporate sources of knowledge and it is a way of increasing our knowledge. This science has made people realize and learn more things than they actually know and it made people understand things around them without having to actually think an explanation behind it.

Bacteria and other microbes can be used to "clean up" an oil spill by breaking down oil into carbon dioxide and water. Two sampl

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%
