Answer:
Carrier proteins move materials from one side of the cell membrane to the other. This is useful for both active transport, meaning you have to transport against the concentration gradient, and facilitated diffusion, a form of passive transport.

In a dihybrid cross, if the genotypes of one the parents is BbTT, what genes would you put on the outside of the Punnett square?
Answers:
BT, Bt, BT, Bt
BT, BT, BT, BT
BB, bb, TT, tt
BT, BT, bT, bT
Answer:
BT, BT, bT, bT
Explanation:
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of one another i.e. one allele of a gene does not hinder the separation of another. The separation occurs via meiosis in such a way that only one allele of a gene is present in each GAMETE.
These gametes are what forms the crossing basis in a punnet square. According to this question involving a dihybrid cross, the genotype of one of the parents is BbTT. The allelic combination of the gametes will be: BT, BT, bT, bT. These gametes will be put on the outside of the Punnett square.
Answer:
BT,BT,bT,bT
Explanation:
It's 50/50.
Which of these is not an example of how substances move within cells?
Answer:
Diffusion
Explanation:
Diffusion is the process of transporting substances through the cell membrane. The cell membrane is semi permeable, which means it only allows certain substances to exit and enter the cell. Substances move from a high concentration to a lower concentration without the use of energy.
Cell cycle is not an example of how substances move within cells. Thus, option D is correct.
What is cell cycle?A cell cycle is a series of events that takes place in a cell as it grows and divides. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
Cell cycle is responsible for growth of cell not for the any substance movement within cell. Thus, option D is correct.

1. Who is widely considered to be the
father of genetics?
A. Gregory Mendel
B. G. H. Hardy
C. William Bateson
D. Reginald Punnett
Answer:
a. Gregory Mendel
Explanation:
Gregory Mendel is the father of genetics
Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.
Therefore, Option A is correct

When living cells break down food molecules, energy is A. Stored as a phosphate group added to ADP. C. Released as heat. B. Stored as ATP. D. All of the above
Answer:
Option B. is correct
Explanation:
ATP stands for Adenosine triphosphate.
ATP is an end product of the following processes:
1. Photophosphorylation
2. Cellular respiration
3. Fermentation.
When living cells break down food molecules, energy is stored as ATP.
Adenosine triphosphate is the main source of energy of the cell
So, option B. is correct.

Armadillos have 32 pairs of chromosomes
18. What is the diploid number (2n) for the somatic cells of armadillos?
19. How many chromosomes are present at the beginning of mitosis in an armadillo cell?
20. How many chromosomes are present in each daughter cell at the end of mitosis?
If Armadillos have 32 pairs of chromosomes;
The diploid number (2n) for the somatic cells of armadillos is 64There will be 64 chromosomes at the beginning of mitosis in an armadillo cell. There will be 64 chromosomes in each daughter cell at the end of mitosis.MITOSIS:
Mitosis is the process by which a single cell produces two daughter cells that are genetically identical to one another. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell.This means that if Armadillos have 32 pairs of chromosomes i.e 64 chromosomes. The following applies:

Answer:
Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.

1.Where is there more atmospheric pressure, in New Orleans, at sea level, or Mt. Everest? Why? a. New Orleans, because pressure increases as you get deeper in the atmosphere and closer to the center of Earth b. c. d. Mt. Everest, because pressure increases as altitude increases New Orleans, because there is less air near Earth's surface Mt. Everest, because pressure decreases as altitude increases
Answer:
a. New Orleans, because pressure increases as you get deeper in the atmosphere and closer to the center of Earth
Explanation:
Low altitudes: There is more atmospheric pressure in comparison with higher altitudes. When closer to the Earth core, the more pressure and temperature there is. High Altitudes: As high increases, atmospheric pressure, and temperature, decreases, leading to a lower oxygen partial pressure in the environment.At sea level, the atmosphere pressures the earth's surface with approximately 1-kilogram per square centimeter strength. This means that at sea level, there is one ton of air making pressure over us. But this air pressure decreases with altitude.
At high level there is less air making pressure from above, and there is less gravity acting. Molecules are more separate from each other, and the density decreases.

C. Bears benefit from eating fish, and the fish are harmed.
D. Bees benefit from drinking nectar from flowers, and the flowers are pollinated.
Answer:
D. Bees benefit from drinking nectar from flowers, and the flowers are pollinated.
Explanation:
Mutualism is when two different living things benefit from each other. When bees drink nectar from flowers, they are benefitting from that because they get nectar. The flowers are also benefitting from this because they are being pollinated.
A. is incorrect because the grass does not benefit
B. is incorrect because the dead animals are dead so they don't benefit from this
C. is incorrect because the fish are harmed and do not benefit from this
Therefore, the only correct answer is D.

The florida panther prefers to prey on wild hogs and deer. As agriculture and housing spread throughout the state, florida panthers began to prey on livestock. What most likely explains why the florida panther began to eat domesticated animals?
Answer:
Wild hogs and deer's food sources were probably disrupted as agriculture and housing spread throughout the state, so they moved to different areas. Since the panther is a carnivore, and livestock was being moved into its habitat, it wouldn't have needed to move since the livestock could replace the hogs and deer.
