How does monitoring environmental parameters affect policies regarding resource use?

Answers

There are many reasons why it is important to monitor the environmental parameters. The activities of the humans had a great impact on the environment. Through monitoring, we will be able to understand and learn the factors that affect the environment and how to minimize it. 

A star at the end of its life-cycle, composed of mostly carbon, is a A. nova.
B. giant.
C. red dwarf.
D. white dwarf.

Answers

A star at the end of it's life cycle is called a white dwarf (answer D). The order of life in the answer choices given is giant, red dwarf, white dwarf and nova. The nova, while the final stage is actually the explosive death of a star. The white dwarf state is a small, hot star that is that is dense in composition and composed of mostly carbon and oxygen. 

Answer: D. White Dwarf

DNA replication occurs at an unbelievably fast rate. Once replication is complete, we can expect to find a _____ number of mistakes. DNA replication occurs at an unbelievably fast rate. Once replication is complete, we can expect to find a _____ number of mistakes. small average larg

Answers

Answer:

small

Explanation:

The overall error rate of DNA polymerase during replication is 10-8 errors per base pair. Repair enzymes fix 99% of these lesions for an overall error rate of 10-10 per bp. That means one change occurs in every 10 billion base pairs that are replicated.

Final answer:

DNA replication is a highly accurate process, occurring rapidly and with a small number of mistakes, due to the efficiency of the DNA polymerase enzyme and the cell's repair mechanisms. However, any uncorrected mistakes can cause significant consequences, like mutations or even diseases like cancer. This process has been closely studied in prokaryotes such as E. coli.

Explanation:

DNA replication, a critical biological process, typically occurs with a remarkably small number of mistakes, thanks to the accuracy of the DNA polymerase enzyme and other repair mechanisms. This process has been particularly well-studied in prokayotes, like E.

coli, which can replicate its 4.6 million base pairs in about 42 minutes, adding around 1000 nucleotides per second.

However, when mistakes do occur and are not corrected, they can lead to mutations which might have serious consequences, such as cancer, particularly if the repair enzymes themselves are mutated or defective.

Which is the main reason cells are replaced in the body?

Answers

The cell are replace in the body because the cells are damaged.
because if the cells wouldnt be replaced then after a cell dies (which happens very rapidly) we wouldnt exist for very long. the body replaces tons of cells on a daily basis, and if the body stopped making new ones to replace the old, we wouldnt have anymore living cells left in our body.

The moon outside is very large, but you cannot see all of it. The calendar shows that the moon was invisible just less than two weeks ago. What phase is the moon in now?

The time when you can't see any of the moon at all is called  "New Moon".

14.77 days later, the phase is "Full Moon".

At which location in Earth’s interior does the top density continue to increase as thickness decreases? inner core outer core lower mantle upper mantle

Answers

Answer: At the inner core of the earth interior, top density continue to increase as thickness decrease.

Explanation:

The Earth is the third plant from the sun and the fifth largest plant. It is the only planet that can harbor life, that have oxygen in the arthmosphere and oceans on the surface. The Earth have three main layer which are the core(the outer and inner core), the mantle and the crust. All the three layers support life existence. The earth inner core is the innermost geologic layer and it is hot and denser. It is a solid ball of 1,220 kilometers. The earth inner core has the highest density (12)than all other layers and it is less thicker than mantle and the crust. Density increase with depth because the pressure increases also.

Answer:

inner core
