Which of the following would cause an error in DNA replication? A. DNA polymerase pairing A with G B. Helicase making a replication fork C. DNA polymerase checking the DNA D. DNA ligase connecting chunks of DNA

Answers

Answer 1
Answer: The correct option is A. DNA replication is the process by which two identical copies of DNA are produce from one original, parent DNA. The process occurs in all living organisms and it is the mean through which traits are passed from parents to offspring. A number of mechanisms has been put in place to ensure that base pairs are accurately copied during the process of DNA replication. For instance, pairing adenosine base with guanosine during the replication process will result in an error, which can have very severe consequences, if it is not corrected.

How do products of meiosis I differ from those of meiosis ll?

Answers

Meiosis I is dedicated to forming two Haploid(half chromosome) cells bby separating each pair of chromosomes (one of each type in each cell) and the recombination, or shuffling of genes on each chromosome with its pair by crossing over, While Meiosis II is meant to split the individual chromatids in the haploid cells to create a total or 4 daughter cells

How does nuclear energy use differ from geothermal and solar energy use?a.
Geothermal and solar energy both have a mining step, while nuclear energy does not.
b.
Geothermal and solar energy both require water, while nuclear energy does not.
c.
Geothermal and solar energy are both renewable, while nuclear energy is not.
d.
Geothermal and solar energy both generate a significant amount of waste, while nuclear energy does not.

Answers

in short the answer is c.
Geothermal energy is produced in geothermal power plants that use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. Because its source is the almost unlimited amount of heat generated by the Earth's core geothermal energy is a renewable source of energy. Solar energy is the energy of the sun that is converted into electricity and it is also a renewable source. On the other hand, the nuclear energy is produced as a result of nuclear reactions and is not renewable. So, nucelar energy differ from geothermal and solar beacuse geothermal and solar are renewable, and nuclear is not.

Which of the following is not a defense mechanism? a) Identifying the emotions you feel. b) Denying that a feeling or situation exists. c) Making excuses for bad behavior. d) Thinking about something other than the negative feeling.

Answers

Answer:

A

Explanation:

For B denying that a feeling exists is trying to avoid a problem, therefore it is a defense mechanism against emotions

For C this is also a defense mechanism because you are making excuses instead of facing your bad behavior up from

And for D you are not accepting the negative feelings and trying to overpower them

Therefore, the correct answer is A

The process of ____________ increases genetic variability as it produces gametes for sexual reproduction.

Answers

The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the  offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

Final answer:

Meiosis increases genetic variability as it produces gametes for sexual reproduction.

Explanation:

The process of meiosis increases genetic variability as it produces gametes for sexual reproduction. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell. During meiosis, genetic recombination and crossing over occur, leading to the production of genetically diverse gametes.
