Answer:
D. Food webs contain many different linked food chains
Explanation:
Answer: False
Explanation:
The activation energy is the energy required which is required to initiate a chemical reaction.
In case of enzyme- catalyzed reaction the amount of energy required to initiate a reaction. More energy is used in product formation.
It is different from the uncatalyzed reaction in a way that the activation energy is more as compared to catalyzed reaction.
Hence, the given statement is not true.
For the answer to the question above, <span>If animals are related they share genes in common. The more genes they share on their DNA, the more alike they may be, like the rodents.
However, the behavior is caused not only by genes but by the environment plays an important part as well.</span>
Answer:
a) All males will have dark wings, all females will have light wings. See attachment
b) Males - 50:50 dark:light, females, 100% dark wings
Explanation:
The ZW sex determination system is different from the XY sex determination system. Females are ZW, whereas males are ZZ (in contrast to XY system where females have two of the same chromosome [XX] and males have two different ones [XY]).
a) The potential genotypes of the F1 are shown in attachment. This shows that all males will have dark wings (Ll) (all heterozygous) and all females will have light wings (l) (all will inherit l allele from father)
b) The potential genotypes of the F2 are shown in attachment. This shows that 50% of the males will have light wings (Ll), and 50% will have dark wings (ll). All of the females will have dark wings (L).
Small populations
In small population sizes, inbreeding, or mating between individuals with similar genetic makeup, is more likely to occur, thus perpetuating more common alleles to the point of fixation, thus decreasing genetic diversity.
