Answer:
I believe "B"
Explanation:
In the Sun, the flows of hot plasma in the convection zone create the solar magnetic field. This is sustained by nuclear fusion in the Sun. ... The number of sunspots on the sun increase and decrease over time in a regular, approximately 11-year cycle, which is, in fact the solar magnetic activity cycle.

The correct answer is D. species.
The definition of a species is termed as a group of interbreeding individuals cannot be easily applied to organisms that they reproduce only or mainly by asexual methods.
Species is termed as the basic unit of classification and taxonomic rank and also unit of biodiversity. It is the largest group of organisms whereby two individuals produce fertile offspring.
They are typically by sexual reproduction. Boundary which is between closely related species they becomes unclear.
Answer: Sudden loss of habitat
Explanation:
Endangered species are animal or plant species that are in danger of going extinct.
This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?
a) Incomplete dominance
b) Genetic recombination
c) Chimerism
d) Codominance
Answer:
d) codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
