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.​

Answers

Answer 1

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.

how does water potential affect molarity or how is molarity and water potential related

Answers

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.

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.

C. It gains an electron
D. It gains a neutron,
SUSAN

Answers

The answer is A it loses and election
Ionization or ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion. Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules and ions, or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected. So it is A

Answer:

D) Krebs' cycle

Explanation:

The stage of respiration shown is pyruvate oxidation. This is the intermediate stage between the first and second stages of aerobic respiration.

The first stage is glycolysis, which is the breakdown of glucose into two molecules of pyruvate. After pyruvate oxidation, the next stage is the Krebs cycle. The Krebs cycle is a series of reactions that release energy through  oxidation of acetyl-CoA.

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.

Includes somatic cells
Heart and liver cells
Sperm and Egg cells

Answers

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.
