They both carry a recessive allele for blue eyes because answer A doesnt state anything about the allele dominance, answer B wouldnt be right because if blue eyes was dominant then the mother would have blue eyes as the dominant gene always shows, but she has brown
Temporary teeth
I -
3/3 C - 1/1 P - 4/4 M - 0/0 = 16 x 2 =
32
Permanent teeth
I -
3/3 C - 1/1 P - 4/4 M - 3/3 = 22 x 2 =
44
where I = incisors, C = canines, P =
premolars and M = molars
Dental formula can be defined as the number of teeth on one
side of the upper jaw over the number the same type of the number of teeth at the
lower jaw. Thus, the formula is for one side of the mouth and the total number
of teeth is the total in the formula multiply by 2.
Answer:
A predominance of pine trees
Explanation:
Usually pine trees become a target of fire and can overcome the soil that has been a exposed to fire. Hence, in a woodland that has been frequented by fire, there is growth of pine trees rather than other trees/plants.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
