Answer:
B. WW or Ww
Explanation:
If the w allele is recessive, that means that the presence of any W alleles will mask the expression of the w allele. So the possible genotypes for no spots and hence solid coat, keeping in mind that there must be two alleles, one from each parent, are WW or Ww.
WW or Ww would both produce phenotypically solid coats. ww would produce a spotted coat.
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
C.
Biotic mean alive, so we can cut off the first 2 easily. Aquatic birds eat frogs, so that one is safe for now. A decrease in something parasitic usually helps the population, so D is out too. The only one left is C.
The best answer is starch.
Starch is a type of carbohydrate.
Carbohydrates are made of simple sugars, namely glucose. A simple sugar is a single molecule of a sugar. A single sugar molecule is called a monomer.
Starch is made of many monomers or units of glucose linked together and is thus called a polysaccharide. When it is broken down, the result is its many glucose units are separated from each other by breaking the chemical bonds that hold them together, and are thus released as simple sugars.
Interspecific competition may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species.
