The correct option is B.
A positive feed back refers to the amplification of a particular effect by its own influence on the process that gives rise to it. In positive feed back, the specific response that is obtained as a result of a process continue to increase as the process continues or increase, that is both the process and the effect generated increase.
#1. Typical United States weather patterns show the continental polar air mass moving south toward the Gulf of Mexico. Why does this air mass movement happen?
C) The polar air mass moves south to replace the rising maritime tropical air mass.
#2. Running a mineral across a porcelain plate to see the color it leaves behind on the plate may be described as testing for D) streak.
#3. D. Carbonization preserves soft tissues of plants or animals as a thin carbon film, usually in fine-grained shale sediments.
#4. We can divide natural resources into two basic categories: renewable and nonrenewable. Consider the bar graph of resource usage. If we wanted to reduce the use of nonrenewable natural resources, it would be least important to A) reduce deforestation.
#5. Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory?
C) It lacked sufficient evidence and explanation.
Hope I helped!!
Answer:
Say the dominant gene is G, for free earlobes. Say the recessive gene is g.
We only need one G for free earloves to show. The possible genotypes are,
Gg and GG.

a geological barrier (like a continent splitting apart) separates a
population of primates, then each population will evolve separately to
fit the different conditions of their environments.
As a hypothetical example, if one part of Pangea went north, the
primates on that part would adapt to cold temperatures. If the other
part went toward the equator, those primates would adapt to heat and
direct sunlight. Eventually they would evolve into different species
over many generations.</span>
Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
