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.
A potentially fatal condition with sudden onset, characterized by uremia, that can be caused by the kidneys not receiving enough blood to filter is called Renal artery stenosis or Acute kidney failure.
- The narrowing of one or more arteries that supply blood to your kidneys is known as renal artery stenosis (renal arteries).
- Your kidneys can't get enough oxygen-rich blood because of artery narrowing.
- To assist in filtering waste materials and eliminating extra fluids, your kidneys require a sufficient blood flow.
- Your kidneys' decreased blood flow could harm renal tissue and raise your body's blood pressure.
- Clogging of the renal arteries. Your renal artery walls are susceptible to plaque buildup from fats, cholesterol, and other chemicals (atherosclerosis).
- Larger deposits have the potential to harden, decrease blood flow, result in kidney scarring, and ultimately restrict the artery.

Answer:
SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level
Explanation:
Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.
It actually could, but no one has the living time to do that. It also could be done with speices names
