In what way does crossing over influence the genetic variation of offspring?
A. Genes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.
B. Chromosomes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.
C. Genes from both parents are kept separate, which reduces the number of possible combinations that the offspring can receive.
D. Chromosomes from both parents are kept separate, which reduces the number of possible combinations that the offspring can receive.
Answer:
A and B are both correct.
Explanation:
Chromosomes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.
Why would a plant cell not burst while an animal cell would undergo cytolysis in a hypotonic solution?
The plant cell has a large central vacuole and creates a stronger exterior.
The plant cell has a rigid cell wall and the pressure from the central vacuoles causes the stiffness of the plant and animal cells do not have a cell wall therefore the boundary of the cell is weaker.
The plant cell is stronger because it has the chloroplast and causes a strong boundary that support the cell due to the glucose that is made from the process of photosynthesis.

What do scientists do when experiments are not possible
Answer:
Well, to be honest I think that they might just figure out another way to do that experiment.
Explanation: My reasoning is, that if an experiment isn't possible due to complications like maybe it could be to dangours or it could have reaction that they don't know about. So if they aren't able to do an experiment then they might find a safer one to do or they might just skip it and research more about it and see how it would react to certan things.

Name and describe 3 ways objects can travel across a membrane. Include what types of objects (H2O, sugar, ect) are moving across the membrane for each way.
Answer:
Osmosis - water
Ions - diffusion
Large proteins - endocytosis
Explanation:
Ions and small molecules can cross the cell membrane by simple diffusion, where they move from a high concentration to a low concentration, down a concentration gradient.
Osmosis is the process whereby water travels across a semi-permeable membrane from a high concentration to a low concentration.
Larger cargo can cross the membrane through a process called endocytosis, where the membrane engulfs the particles and brings them inside the cell, encased in a vesicle.
Which property of water allows water to be conducted up to the leaves?
Answer:
Cohesive nature of water
Explanation:
Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves.

Complete the following table comparing and contrasting diploid and haploid cells.
Diploid
Haploid
Description
Homologous chromosome pairs
Designated N
Designated 2N
Has one member of each
homologous chromosome pair
Includes gametes
Includes somatic cells
Heart and liver cells
Sperm and Egg cells
Answer:
Please find the description and it's pair below:
Homologous chromosome pairs - DIPLOID
Designated N - HAPLOID
Designated 2N - DIPLOID
Has one member of each
homologous chromosome pair - HAPLOID
Includes gametes - HAPLOID
Includes somatic cells - DIPLOID
Heart and liver cells - DIPLOID
Sperm and Egg cells - HAPLOID
Explanation:
1. Diploid organism is an organism with two sets of chromosomes, with each set contributed by each male and female parent. Chromosomes from the male parent is found side by side with chromosomes from the female parent to form HOMOLOGOUS CHROMOSOME PAIR in a diploid organism. Diploidy is denoted by 2N, where N represents number of one set of chromosomes. Diploid cells include somatic or body cells such as heart and liver cells.
2. Haploid organisms are organisms that contain one set of chromosome, formed as a result of meiotic division of diploid cells. Hence, a haploid cell contains one member of each homologous chromosome pair. Haploidy is denoted by N, meaning number of one set of chromosome. Haploid cells include gametes or sex cells such as sperm and egg cells.

are animals phalanges fused
together?
The phalanges /fəˈlændʒiːz/ (singular: phalanx /ˈfælæŋks/) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.

A species is a group of organisms capable of mating and producing offspring, and speciation is the process of forming a new species.
One way a new species may form is by geographic isolation. This occurs when members of a population are physically separated, for example, by a river, or a desert.
After the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will...

how does water potential affect molarity or how is molarity and water potential related
Answer:
If the solute concentration of a solution increases, the potential for the water in that solution to undergo osmosis decreases. Therefore, the more solute that is added to a solution, the more negative its osmotic (solute) potential gets.
Where can earthquakes occur?
Question 12 options:
at a convergent plate boundary
at ALL kinds of plate boundaries
at a divergent plate boundary
at a transform plate boundary
Answer:
at a transform plate boundary
Explanation:
Transform faults are found where plates slide past one another. An example of a transform-fault plate boundary is the San Andreas fault, along the coast of California and northwestern Mexico. Earthquakes at transform faults tend to occur at shallow depths and form fairly straight linear patterns.

What is genetic variation?The difference in DNA between individuals or between populations is referred to as genetic variation.
Mutation and genetic recombination are two of the many sources of genetic variation. Although mutations are the ultimate source of genetic variation, other mechanisms such as genetic drift also contribute to it.
Heredity, also known as inheritance or biological inheritance, is the transmission of traits from one generation to the next.
Each of your parents has two copies of each of their genes, and each parent passes on only one copy to you.
Many of your characteristics, such as hair and skin color, are determined by genes that are passed down to you.
Thus, the correct option is B.
