Answer:
increasing growth and decreasing rate of growth
Explanation:
Global population growth slowing due to greater longevity and lower fertility rates. The world's population is getting older and growing at a slower pace but is still expected to increase from 7.7 billion currently to 9.7 billion in 2050

Answer:
A. will not change from generation to generation.
Explanation:
For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:
-The population is large enough.
-Individuals of the population exhibit random mating
.
-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.
Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
Sexual reproduction produces genetically different offsprings which do possess variations, hence better chance to survive in the environment.
Option C
<h3><u>Explanation:</u></h3>
Sexual reproduction is the process of reproduction where there's a fusion of gametes from a male and female of the same species, resulting in a zygote and eventually an offspring. Sexual reproduction is very advanced type of reproduction which is very expensive for an organism. Much of the energy of the organism is spent to produce gametes and other necessary processes for reproduction.
Gametes of the sexual reproduction is produced mainly by means of meiotic cell division. This involves crossing over and chaismata formation which helps in genetic variations in the offspring. These variations help the species to survive unknown changes in environment, and helps to adapt quickly lessening the chances of extinction. So sexual reproduction has modified various times in different groups of species.
Answer:
The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes. ... A chromatid, then, is a single chromosomal DNA molecule.
