When does facilitated diffusion occur?
Answers
Answer:
The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.
Explanation:
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins.
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Water lilies grow in freshwater ecosystems. When a water lily plant is kept in seawater, it wilts. Which statement best describes what happens to the water lily plants in seawater?
a.Water moves out of the cells of the lily by osmosis
b.Water moves into the cells of lily by osmosis
c.The cells of water lily plants get less oxygen from the seawater
d.The cells of water lily plants lose all important nutrients to the seawater
IN A TEST RN!!!!
Answers
explanation: osmosis is a process where water moves from a less concentrated solution to a more concentrated one. seawater has more salt than the water inside the lily plant, so this causes the water from inside the plant to move out. without much water inside, the plant begins to wilt.

Which of the following occurs just before the cell enters the G2 stage of
the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides
Answers
Answer:
DNA replicates
Explanation:
S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration

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.

Which statement below best describes the purpose of meiosis in creating gametes?
Answers
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.
What is meiosis?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.
In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

B) Glycolysis
C) fermentation
D)krebs cycle
Answers

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.
