Populations can have variety, despite being made up of
the same species. If a population has different expressed
traits, this can be due to different inherited alleles. The
frogs below are the same species, but they have different
shades of green based on their inherited alleles. In a
particular environment, lighter green frogs are easier to see
by predators. Explain how natural selection could lead to a
change in allele frequency.
Answer:
The lighter frogs will be eaten and will not be able to reproduce offspring with the light green trait. Darker green frogs will be able to reproduce more dark green frogs. Eventually most/all frogs will be a darker green because they carry a trait that improves chances of survival.
Which statement is true regarding meiosis in cells?
O In anaphase I, sister chromatids are pulled apart at the centromere.
O In prophase II, homologous chromosomes are paired up in a tetrad.
O The daughter cells do not undergo cytokinesis at the end of meiosis
The products of telophase I are two haploid daughter cells..
answer : the last one is true, yeah !!
d :: the products of telophase 1 are two haploid daughter cells ..
Chromosomes finish migrating to opposing ends of the cell in telophase I. Cytokinesis then creates two daughter cells. Therefore,option (D) is correct.
What happens is telophase I?The parent cell has two poles at Telophase I of the meiotic cycle, each with a full complement of haploid chromosomes (which still have their sister chromatids). Now, a cleavage furrow forms, separating the cytoplasm of the cell in two (a proccess ultimately called cytokinesis).
The homologous chromosomes divide into distinct nuclei during telophase I. The cell restores its nuclear membrane, deconstructs the microtubules and spindle fibers, and then initiates cytokinesis. After then, the cell enters a phase of rest known as interkinesis.

How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.

Hope I've helped
The control of the mosquito population helps in managing the outbreaks of malaria. Infantile paralysis is another name for polio. Travelers to the Central and South America can get vaccinations for rabies. Thus, the correct options for 1, 2, and 3 are A, A, and B, respectively.
What is Malaria?Malaria is a serious diseases which could be a fatal disease sometimes and it is caused by a parasite that commonly infects a certain type of mosquito species which feeds on the human blood. People who get the malaria infection are typically very sick with high fevers, shaking chills, and flu-like illness and other symptoms.
Infantile paralysis is another name used for polio. Polio is a condition which is caused by a virus that mainly affects the neurons in the spinal cord or the brain stem. In its most severe form, polio infection can lead to a person being unable to move certain limbs or joints, also called paralysis.
Therefore, the correct options for 1, 2, and 3 are A, A, and B.

How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.
