Answer:
1. Individuals in a species vary in characteristics because of differences in their genes.
Individuals will be born with various characteristics due to their genes for instance some people are short and other are tall.
2. Individuals have to compete when resources (such as food) are limited.
Resources are generally limited so individuals would have to compete t get those resources and survive.
3. Individuals with variations that help them get more of the resources are more likely to survive.
Some of the characteristics that these individuals have which are different will give them an edge and enable them to get more resources and thus survive.
4. Individuals that survive can pass their genetic variations on to their offspring.
The individuals that survive will now have offspring and will pass on their genes to their offspring which give give them the same edge their parents had.
5. Over time, there are more individuals with the variations that are well adapted to the environment.
Eventually there will be more of those offspring that can adapt as opposed to those who couldn't and keep dying out.

Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.

Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answers
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.

You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answers
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

this blood vessel?

3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answers
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Which type of reproduction is responsible for genetic variation?
Answers
Answer:
sexual reproduction
Explanation:
Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Other reproductions like asexual, budding or fragmentation don't produce genetic variation.
The type of reproduction is responsible for genetic variation is - sexual reproduction.
Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.
Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answers
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).
