Answer:
I think the answer is false
Answer: False
Explanation:
Hope so
A concentration gradient is the difference between
two concentrations
Active transport allows cells to transport molecules
against a concentration gradient
Diffusion results in a net overall movement from a low
concentration to a high concentration
In diffusion particles are moving around randomly in
all directions
Osmosis requires energy from respiration to be carried
out
Partially permeable membranes allow any molecules
to pass through them
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.

I took the quiz and got the answer correct
:)
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.

Please help meeeeee
Answer:
Try "all living things are made of cells". I'm really just guessing,but good luck!!!!!!
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:
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.
