Answer:
A B and C
Explanation:
Crossing over breaks, exchanges and rejoins chromosomes at corresponding points so introduces genetic variation. Because of crossing over offspring has characters of both parents.
Also independent assortment means that during separation of the chromosomes in anaphase, any chromosome can pair up with another. So for example if we have one parent plant with yellow and wrinkled seeds and other one with green and round seeds, then the gene responsible for round seed can pair up with either of the genes responsible for yellow seeds or green seeds. Hence the characters of offspring differ from the parents, it can have yellow round seeds or yellow wrinkled seeds and so on.
Mitosis will only produce 2 daughter cells which are exactly like their parent cells and are also identical to each other. Binary fission is a form of Asexual reproduction so it does not involve shuffling of genes from 2 parents.
Because of fertilization of egg with a sperm the maternal genes and paternal genes mix together. So it also produces genetic variations.

The presence of a cholesterol in the plasma membrane of some animals
Answer:
The amount of cholesterol in animal plasma membranes regulates the fluidity of the membrane and changes based on the temperature of the cell's environment. In other words, cholesterol acts as antifreeze in the cell membrane and is more abundant in animals that live in cold climates.

How is a proton gradient formed across the inner mitochondrial membrane?
Answer:
Energy is released in these “downhill” electron transfers, and several of the protein complexes use the released energy to pump protons from the mitochondrial matrix to the intermembrane space, forming a proton gradient.

Answer:
Keystone Species: Kangaroo Rat Keystone species are species whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system. Hawk (predator)/lizard (prey). scorpion (predator)/insect (prey). if their is no relationship between these two then the scorpions will die off and the insects will thrive.

why cellular respiration and photosynthesis are a
cycle.
Cellular respiration and photosynthesis are referred to as a cycle because the end product of one process serves as the starting material for the next reaction. During cellular respiration, sugar and water are the starting materials, and carbon dioxide and water are the byproducts. Water and carbon dioxide are the starting material for photosynthesis.
ExplanationA cycle is a series of steps that are repeated, which defines this! :)

why is cooking faster with a pressure cooker
As the pot is heated, the temperature inside increases until the water starts to boil. ... At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.
In urban areas the food insecure families are those whose working members are generally employed in low paid occupations and casual labour market.

Which of the vitamins would be potentially the most dangerous to
consume in high does (greater than 10 X RDA) as single micronutrient?
O vitamin A
O vitamin B-12
O vitamin
O riboflavin
????
Answer:
Vitamin A
Explanation:
Most people with vitamin A toxicity have a headache and rash. Consuming too much vitamin A over a long period of time can cause coarse hair, partial loss of hair (including the eyebrows), cracked lips, and dry, rough skin. Chronic consumption of large doses of vitamin A can cause liver damage.
Consuming too much vitamin A over a long period of time can cause coarse hair, partial loss of hair (including the eyebrows), cracked lips, and dry, rough skin. Chronic consumption of large doses of vitamin A can cause liver damage. It can also cause birth defects in a fetus. Later symptoms include severe headaches and general weakness. Bone and joint pain are common, especially among children. Fractures may occur easily, especially in older people. Children may lose their appetite and not grow and develop normally. Their skin may itch. The liver and spleen may enlarge.

There are 100 ants in an ant farm that is 10 inches by 5 inches. What is the population 1 density? (Show your work)
The population density would be 2 ants/square inch
Population density is defined as the population size of a species of organism per unit area of the habitat occupied.
In this case, the population size of ants in the ant farm is 100 while the dimension of the ant farm is 10 inches by 5 inches.
Area of the ant farm = Length x breadth
= 10 x 5
= 50 square inch
Population density of ant = population size/area
= 100/50
= 2 ants/square inch
More on population density can be found here: https://brainly.com/question/16894337?referrer=searchResults

Is phrenology an example of science or
pseudoscience? Explain your answer.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience. It is the belief that studying the conformation of the skull reveals the character traits and mental faculties of an individual, a conclusion not at all rooted in fact but nevertheless studied and pursued as such thereby giving a false sense of being based in scientific methods.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience because Gall held beliefs and ignored any information that didn't align with his beliefs. This is a direct example of Gall using pseudoscience and testing his hypothesis with bias through his belief.

If you place yeast, sugar and water in a sealed bag and in the sun , what two things will be produced
Answer:
Explanation:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

The period of revolution of the earth is called a ?
Orbit
Day
Year
Month
Answer:
Explanation:
A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
Answer:
a year
Explanation:
The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year.

A disputed paternity case! Hermione’s new baby has a blood type of O. Her blood type is B and Ron Weasley is A. Harry Potter (blood type AB) insists he is the child’s father. CAN THIS BE TRUE???!
Answer:
No becuase one of the parents needs to have type O
Explanation:
No, this cant be true because in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]".
What type of alleles are blood types?An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele.
Codominant alleles in humans are responsible for determining blood types. There are three distinct alleles, and they are denoted by the letters IA, IB, and i. The IA and IB alleles both have co-dominant inheritance, but the i allele has a recessive inheritance pattern. Type A, type B, type AB, and type O are the four different human phenotypes that are possible for the blood group.
Therefore, in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]"
