Completed part of the questionErrors in copying can result in changes in the DNA sequence that could be inherited by future generation.

Answer:

DNA stores genetic information in the sequence of its bases

DNA can be replicated by making complementary copies of each strand

Errors in copying can result in changes in the DNA sequence that could be inherited by future generation.

Explanation:

the fact that DNA is located in the Nucleus is not related to double strands.

the DNA csn change is not relevant ,

 therefore the above 3 options are the correct answers.

Why do paleontologist study fossils ?

Stells [14]

Answer:

Paleontologists study fossils so that we can understand the evolution's from past species to the current ones. It also opens a window to discovering exactly how long earth has been around by finding out the age of the fossil itself. Though paleontology has been in the decline recently, and i'm sure we haven't found out all we need to know from these fossils.

If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures

Brilliant_brown [7]

Though there's no question in the statement above I would assume that you are asking about the pH of the water that is acidic. The correct statement would be:

Any liquid that has a pH less than 7 is called acidic, a pH above 7 is basic or alkaline.

The water in the swimming pool has a high acid concentration due to the chlorine which causes the effect of redness in the eyes.

strojnjashka [21]

Answer:

The correct answer will be option-D

Explanation:

Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.

The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.

Thus, option-D is the correct answer.
