Identify all of the true statements:

A concentration gradient is the difference between
two concentrations

Active transport allows cells to transport molecules

Diffusion results in a net overall movement from a low
concentration to a high concentration

In diffusion particles are moving around randomly in

Partially permeable membranes allow any molecules
to pass through them
​

Answers

Explanation:

a) True. The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.

b) True. Active transport requires cellular energy to achieve this.

c) False. Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.

d) True. For diffusion to work, the particles must be able to move around.

e) True. Osmosis requires energy from respiration to be carried

out.

f) False. Partially permeable membranes allow  only water but not other dissolved substances to pass through.

Which best describes the negative impact of human water use? A. Food can be produced in dry areas. B. Increased runoff carries fertilizers. C. Food can be produced through drought years. D. Water can improve the livelihood of farmers.

Answers

Answer is B. Increased runoff carries fertilizers.

Runoff is movement of water over land as surface water instead of being absorbed into groundwater or evaporating. Runoff is that part of the precipitation, irrigation water that appears in uncontrolled surface streams, rivers, drains, or sewers. When runoff flows along the ground, it carries soil contaminants such as fertilizers, pesticides to other parts of land that become discharge or overland flow.

Why is it important forscientists to be able to remove DNA from an organism? List two reasons.

Answers

A scientist has the ability to remove DNA from an organism, they can manipulate, classify, and observe the DNA.
 By studying DNA, a scientist can identify genetic diseases or disorders. By experimenting with or manipulating with DNA, the scientist can possibly find cures for the causes.
DNA is a thread-like chain of nucleotides which carries genetic instructions and is used in the growth functioning, reproduction, and development of all many viruses and known living organisms. RNA and DNA are termed as nucleic acids alongside lipids, proteins, and carbohydrates.
RNA and DNA are major types of macromolecules that are essential for well-known forms of life.
  • It is important for scientists to be able to remove DNA because it enhances biotechnological studies.
  • The removal of DNA by scientists fundamentally helps in determining the unique features and characteristics i.e. size, function, etc of a particular DNA.
  • Additionally, it is also important for scientists to remove DNA because it aids in the determination of the paternity of an organism.
  • Another importance is, for the scientists to be able to study genetic origin and causes of different kind of diseases of an organism.  The removal of DNA helps scientists to be able to sequence genomes, detect viruses and bacteria in the environment.

Further Explanation:

DNA means deoxyribonucleic acid. It can be referred to as the hereditary particle that can be found in every individual and all other organisms in the environment. DNA is usually located in the cell nucleus, and a very few amount are located in the mitochondria of living organisms.  

It is important to note that series of information are stored in the DNA and the information is formed in four chemical bases:

  • Adenine
  • Guanine
  • Cytosine
  • Thymine

More than 2 million bases can be found in the human DNA and more than 99% of those bases always the same in every individual.

The information gotten from an organism makes research easier for scientists in getting a rapid and efficient result.  And due to the removal of DNA scientists are able to sequence genomes, detect viruses and bacteria in the environment.
