I need help asap with this question as well Organisms evolve, through the process of natural selection, in ways that enable them to live successfully in their environments. Choose three biomes or aquatic ecosystems and describe how abiotic factors have influenced the organisms that live there

Answers

Answer 1
Answer:

Soil, Temperature, and water would be practically the 3 biomes or the aquatic ecosystems. They are both natural and enables you to live successfully. So as for the organism that live there, like plants, the sun supports the plants, also water, and also the soil from the ground. Therefore, those would be the 3.

Darwin observed how farmers and breeders produced many kinds of farm animals and plants. These plants and animals had traits that were desired by the farmers and breeders. He also noticed how the study of similar body structures and vestigial organs could add to the evidence of evolution. After performing several breeding experiments, he came to certain conclusions and formulated some theories. His theory of evolution and natural selection is the most accepted one. What is the reason behind the acceptance of Darwin's theory?

Answers

Natural selection was actually accepted by a lot of people who knew what Darwin was talking about (e.g. Scientists and biologists..and other scientist relative to science were called).
 Darwin  was the first to realize the mechanisms that fundamentally drive this change: variation and natural selection. His theory caused controversy among his contemporaries but were  gradually accepted. Darwin's theory earned general scientific acceptance after he published his "On the Origin of Species" in 1859.

 What is the DNA backbone made of?- a nitrogenous base and a sugar molecule    
  - nitrogenous bases, sugar, and phosphates   
  -  sugar and phosphates
  - a polymer of nitrogenous bases

Answers

DNA or deoxyribose nucleic acid is a genetic material, which transmits information from the parent cell to the offspring. It is present in the nucleus or found in the nucleoid.

The correct option is:

Option C. sugar and phosphates

DNA is made up of:

  • Nitrogenous bases such as adenine, cytosine, thymine, and guanine are involved in the specific pairing that provides the helical structure of DNA.

  • The DNA consists of a pentosesugar, known as deoxyribose.

  • The backbone of the DNA is made up of the phosphate group attached with sugar, which provides DNA with a negative charge.

Thus, the DNA backbone is made up of phosphate and pentose sugar.

Therefore, Option C is correct.

. All BUT ONE statement describes an advantage of meiosis.. A). Variation is aided by crossing-over which occurs during meiosis.. B). Meiosis ensures daughter cells receive one of each kind of gene and half the chromosome number.. C). Independent assortment provides a huge number of possible genetic combinations in daughter cells.. D). Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms.

Answers

Answer:

All statements except "D). Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms" describe the advantages of meiosis.

In multicellular organisms, growth and repair of the tissues are achieved by mitosis.

Mitosis is the process in which parent cell divides into two daughter cells each with the same and an equal number of chromosomes as present in the parent cell.

It helps in producing new cells and replacing the old or damaged cells.

It generally takes place in all the cells of the body (somatic cells) except germ cells.
