An example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.
What is Gene Flow?Gene flow, which can also be referred to as gene migration, is the transfer of genes or genetic material from one population of a species to another.
Migration of humans from one region to another leads to people of one race intermarrying with people of another entire race.
For example, A European migrating to North America, and getting married to a North American thereby giving birth to offspring exhibiting traits of booth a European and a North American. A gene flow has occurred.Therefore, an example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.

On average, Hepatitis A has an incubation period (the length of time before a person shows illness symptoms) of:
Hepatitis A affects the liver. The incubation period of hepatitis A is around 28 days.
What is an incubation period?An incubation time is a period between the infection and the actual appearance of the symptom. It can be said that the time taken for the hepatitis A virus to show its symptoms like nausea, fever, and abdominal pain after infection is incubation time.
Hepatitis A virus spreads through contaminated food and water and is preventable by vaccines. It takes approximately 28 days for the virus to cause the symptoms of the disease from the time of its infection period.
Therefore, the incubation time of the virus is 28 days.

differentiate between the chromosome theory of inheritance and the gene chromosome Theory
Answer:
The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.

Why did we look at seeds in the soil as well as the seeds found in the elephant poop
Explanation:
It is Because the poop of elephant are a lot of nutrients
Elephant is a herbivore and all he eats is plants and plants based food. The poop of elephant is going to be full of seeds as per the diet of the elephant.
What are herbivores animals ?The animals which rely on plants and plants based food for survival are called herbivores. Example are : deer, elephant, cow, buffalo etc.
This is a source of pollination as well and the name is called zoophily where the male reproductive unit of plants reached female unit via animals as carriers.

Explanation:
The three standard sex symbols are the male symbol ♂ and the female symbol ♀, and the hybrid symbol ×. They were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by Carl Linnaeus in 1751.

explain why animals exhibit differences in their essential food requirements?
Explanation:
Environment affects animal behavior by changing the availability of survival resources like food & shelter, as well as situational things like proximity to human activity. Sometimes the same species of animal will behave completely differently in a forest environment compared to an urban environment.

What is natural selection? Is it similar to survival of the fittest? How are the 2 alike? How are they different?
Answer:
Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
Explanation:
Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:
1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.
2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).
3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.

Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.
If white wool (W) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? Explain your answer.
Answer:
No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.
