Nucleus is the correct choice, bacteria cells lack a Nucleus
Answer:
The leaf population will decrease
Explanation:
if there are more caterpilliers they need to eat more so they would eat more leaves.
Answer:
heredity
Explanation:
Heredity is the passage of information that specifies an organism's traits encoded in genes from one generation to the next. Variations refers to the differences between individuals. The study of these variations and how they are inherited from parents to offspring is called genetics.
Answer:
9. Bees play a very important role in relation to agricultural production. Indeed beekeeping is a vital part of our agricultural system. Apart from crop plants which are highly dependant on bees, the presence of honey bees also improves the quality and quantity of crops in general.
10. Use insect repellent. Permethrin-impregnated clothing and insect repellent have not been proved to be particularly effective against tsetse flies, but they will prevent other insect bites that can cause illness. The World Health Organization has targeted West African trypanosomiasis for elimination as a public health problem by 2020.

Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.
