This suggestion BEST illustrates: an evolutionary perspective.
Explanation:
It has been observed that older men tend to marry younger women and women prefer to marry older and taller men. This could be thought of as a evolutionary perspective because by selecting such mates they make them socially more fit. Because when men marry younger women they tend to stick to the single relationship as per their psychological nature. Again when women marry older men they ensure their safety.
Ans. False.
Coral reefs can be defined as underwater ecosystems, characterized by coral (marine invertebrates) skeletons. Coral reefs can survive only in clean and clear water. Pollutants and sediments smother the coral reefs, reduce water quality, and enhance the growth of damaging algae.
Pollution also makes coral reefs to become susceptible for disease, which impede growth and reproduction of corals, and cause damage to coral reefs.
Thus, the given statement is false as coral reefs are affected by pollution.
Answer:
This is because Protons are moving down a concentration gradient.
Answer:
Cell 3
Explanation:
Cell 1:
4 x 3.14 = 12.56 - Surface area
4/3 x 3.14 = 4.18 - area
Cell 2:
16 x 3.14 = 50.24 - Surface area
32/3 x 3.14 = 33.47 - area
Cell 3:
36 x 3.14 = 113.04 - Surface area
108/3 x 3.14 = 113.04 - area
Ratios:
Cell 1:
12.56:4.18 = 1:1/3
Cell 2:
50.24:33.47 = 1:5/6
Cell 3:
113.04:113.04 = 1:1
It is evident from the pedigree that this disease only affects the males. This leads us to the conclusion that this trait must be a case of the Y-linked inheritance.
The trait we are examining is located on the Y chromosomes that is present only in males and inherited from fathers to sons.
