(negative 3 + 8) divided by 2

c
(negative 3 + 8) divided by (negative 2)

d
Negative (3 + 8) divided by 2

Answers

Answer:

B

Explanation:

The negative goes by the 3 because it is 3 degrees below zero. To find averages, you add the numbers and divide by how many numbers there are. in this case, it would be (-3+8)/2

B. to limit the size that cell can reach
C. To organize the cell's internal contents
D. to protect the cell from harmful substances in the environment

Answers

Answer:

D. to protect the cell from harmful substances in the environment

Explanation:

Cell membrane is also known as plasma membrane is a biological membrane that differentiate the internal organelles of the cells from the outside environment. Cell membrane is made up of phospholipid bilayer with embedded proteins.

The main or primary function of cell membrane is to protect cell from harmful substances in the environment as it is the outer convering of the cell. cell membrane regulates movement of substances in and out of cells which restricts entry of harmful substances and hence called as selectively permeable membrane.

Hence, the correct option is D.

B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.

Answers

Answer:

A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.

Explanation:

Some inherited genetic mutations can be good for the offspring.

What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.

Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.

"The cricket population would increase"

Explanation:

Without mice as a natural predator, there would be no regulation as to how many crickets live in an area, thus there would be an excessive amount of breeding which can lead to mutations and more sick crickets than healthy ones. The mice pick off the sick/ slower ones so the naturally stronger crickets can pass on their genes to future generations.

Answer:

The cricket population would increase.

Explanation:

If there were no more mice to eat the crickets, the crickets would have a larger population.

Select the living organisms that will decrease as a result of the loss of coral in the food web.

Answers

Answer:

Butterfly fish, Triggerfish, parrotfish, and sharks

Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.
