Explanation:
Explain what factors can lead to genetic
variation within a population.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Explanation:
We know that the momentum of a body is defined as the product of mass and velocity of the body.
Let us now obtain the momentum for each item on the list;
Football player = 100 * 10 = 1000 Kgms-1
Skier = 60 * 20 = 1200 Kgms-1
Frog = 0.9 * 12 =10.8 Kgms-1
Meteorite = 0.1 * 1000 = 100Kgms-1
Base ball = 0.14 * 30 = 4.2 Kgms-1
Satellite = 3000 * 8000 = 24000000 Kgms-1
Steel ball = 2.0 * 2.8 = 5.6 Kgms-1

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.
B. Megakaryocyte: Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.
C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies. Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.
D. Basophil: Granulosites. Immune System cells. in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.
E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.
F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections. Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.
G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.
H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments
I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.

Explanation:
If the DNA integrates properly into the germ cells, the adult fly will contain _________________ that contain _____________________________. After mating, these flies can then produce progeny that will contain ______________________.
Answer:
Five pairs of autosomal and one pair of heterochromatic sex chromosomes.
Explanation:
The adult fly will contain 12 number of chromosomes that contain five pairs of autosomal and one pair of heterochromatic sex chromosomes. After mating, these flies can then produce progeny that will contain diploid i. e. double number of chromosome. One set of half chromosomes from the male fly while the other half chromosomes comes from female fly so the offspring will receive double number of chromosomes.

Why would looking for the persons responsible for sneaking endangered species (rare birds, for example) into the United States be considered a job for a forensic scientist
Answer:
Forensic scientists are able to find the answer.
Explanation:
The persons responsible for sneaking endangered species into the United States be considered a job for a forensic scientist because forensic scientist is able to find out the persons. Forensic scientist are the investigators who collect evidences from the crime scene and leads to the person who commit crime. So the forensic scientist is the only person who find out the persons responsible for sneaking endangered species.

Margo notices that waves start passing her more often. What can she conclude about the frequency and wavelength of the waves?
Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.
What is Wavelength?Wavelength may be characterized as the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
The frequency or the energy of the wave is inversely related to the wavelength of any wave. This is because when frequency increases, wavelength (λ) decreases, and vice-versa. While the energy of the wave and frequency is directly related to one another.
Therefore, Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.

What is actually cycled in a web of organisms?
Answer:
Carbondioxide gas.
Explanation:
Carbondioxide gas is actually cycled in a web of organisms, The plants takes carbondioxide gas for the process of photosynthesis, this plant is eaten by herbivores for energy and carbondioxide is released in the process of respiration. After that, carnivores feed on these herbivores and oxygen is used in the breakdown of food for releasing energy and carbondioxide gas is also released from the body through breathing so the cycle of carbondioxide gas is continue.
