For this structural characteristic, decide if it is a characteristic of DNA, a characteristic of RNA, a characteristic of both or a characteristic of neither? It contains thymine as a base

Answers

Answer:it is a characteristic of DNA

Explanation:

Deoxyribonucleic acid(DNA) is made 5 carbon deoxyribose sugar, phosphate group,Nitrogenous base which include purine and pyrimidine. Purine base compose of Adenine and guanine while pyrimidine base compose of Cytosine and thymine.

In Ribonucleic acid (RNA) we have 5 carbon ribose sugar, phosphate group and nitrogenous bases which are purine and pyrimidine. Purine consist of Adenine and guanine while pyrimidine compose of Cytosine and Uracil where thymine in DNA is replaced by Uracil in RNA. This makes Thymine a components of DNA not RNA.

Explanation:

The term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype is?
A. Recessive
B. Nucleus
C. Dominant
D. Eukaryotic

Answers

Answer:

A. Recessive

Explanation:

Only answers A and C can be used to describe an allele, so B and D can't be it. If the allele was dominant, only one copy would be necessary for the phenotype to be expressed (ex. heterzygous green peas are still green, even though they carry a yellow allele). Therefore, since 2 copies are present for this phenotype, it must be recessive.

Which answer best identifies the difference between the two types of cellular transport? (B.4B) Question 3 options: Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.

Answers

Answer:

Active transport uses ATP to move molecules against the concentration gradient.Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient

Explanation:

Transmembrane proteins, among others, are the channel proteins and the carrier proteins, and they are in charge of substances transport into or out of the cell.

Channel proteins are involved in passive transport, and facilitated diffusion is a kind of passive transport. Facilitated diffusion transport hydrophilic molecules that can not freely move through the membrane. Channel proteins carry them from one side to the other of the membrane, following the electrochemical gradient, so they do not need energy to carry in or out substances. Uncharged molecules´ movement depends on concentration gradients, while ions´ movement depends on an electrochemical gradient.Carrier proteins are involved in active transport. Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side to a high concentration side. The used energy comes from ATP (Na-K bomb) or the membrane´s electric potential.

How does random fertilization add to the genetic variation?

Answers

Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. Any of the genetically unique sperm generated by a male may fertilize the genetically unique egg produced by a female.

Which of the following statements is correct?
A. Landfills solved pollution problems caused by waste disposal.
B. Wastewater from cities no longer carries toxic chemicals into waterways.
C. Laws regulating waste disposal have put an end to pollution problems caused by waste.
D. Much of the pollution in our environment is a byproduct of inadequate waste disposal.

Answers

Answer:

D

Explanation:

all the others are false

Much of the pollution in our environment is a byproduct of inadequate waste disposal, hence option D is correct.  

What are the problems of waste disposal?

There are some problems caused by solid waste disposal include: finding suitable landfill locations, groundwater pollution, and soil pollution.

Landfills have not solved pollution problems caused by waste disposal, because it creates soil pollution in the area where waste is disposed of, which decreases the fertility of the soil.

Wastewater from cities carries toxic chemicals into waterways, which is the major cause of water pollution in that area. There are some laws that regulate pollution, but not all the person follows them.

Therefore, waste disposal is the major factor of pollution.
