Answer:
5. c. active transport of molecules across a membrane
6. b. osmosis
7. d. water entered the cells of the lettuce by osmosis
Explanation:
5. The diffusion of water does not involve the budding of the cell membrane. The production of proteins amino acids and asexual reproduction are unrelated to the movement of molecules across the cell membrane. Therefore, this is active transport of molecules across a membrane.
6. The diffusion of water from a high concentration to a low concentration of water across a selectively permeable membrane is called osmosis. Transpiration is the process by which water leaves plant cells. Active transport requires energy. Capillary action is when water moves as a result of adhesion/cohesion.
7. When water enters the cells by osmosis, the cells become more turgid, making the lettuce crisp.

B) Glycolysis
C) fermentation
D)krebs cycle
Answers
Image Attached
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.

*
Embedded in the plasma membrane
Dissolved in the cytosol
Suspended in the stroma of the chloroplast
Bound to free ribosomes
Based on the diagram, what is the site of modification and packaging of
proteins and lipids prior to export from the cell?
Answers
Answer:
1. Embedded in the plasma membrane
2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.
Explanation:
1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.
2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.
The most likely location of cholesterol in an animal cell is A. Embedded in the plasma membrane.
Based on the diagram, the site of modification and packaging of proteins and lipids prior to export from the cell is the Golgi apparatus.
Cholesterol simply means a fat molecule that is formed in the smooth endoplasmic reticulum of animal cells.
It should be noted that the cholesterol is then sent It is then to the plasma membrane,
The Golgi apparatus is an organelle that can be found in eukaryotic cells. The function of the Golgi apparatus is the modification and the packaging of the lipid molecules and the protein molecules that are produced.

Which of the following cell transport processes would be relatively unaffected if a cell no longer had access to glucose? Choose 1 answer: Choose 1 answer: (Choice A) A The transport of calcium into a muscle cell via facilitated diffusion. (Choice B) B The transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient. (Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.
Answers
The process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.
What is Cellular respiration?Cellular respiration may be defined as the chemical process through which the breaking down of food occurs with the liberation of energy. This process takes place in the excess of oxygen and constructs energy from carbohydrates (sugars).
The excess glucose delivers the required energy for the cell to perform its metabolic activities. But when the amount of glucose is not significantly present in the cell, the process of transport of calcium into a muscle cell via facilitated diffusion remains unaffected.
This is because the transport of calcium occurs due to paracellular passive transport without the utilization of energy. While the rest of the process requires energy for the transport.
And due to a lack of glucose, cells do not have the ability to derive energy in form of ATP.
Therefore, the process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

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.

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.
