• Two leak-proof bags were set up. • One bag was made from artificial partially permeable membrane (Visking tubing). • The other bag was made from a piece of small intestine containing living cells, with its inner surface inside the bag. • The bags were filled with equal volumes of a dilute glucose solution. • The bags were suspended in the same glucose solution for two hours. • After two hours, the volumes of the bags were measured and the contents were tested for the concentration of glucose. Inside the bag made from small intestine the volume and concentration of the glucose solution decreased. There were no changes to the volume and concentration in the Visking tubing bag. (c) State and explain the process responsible for the decrease in the glucose concentration in the bag made from small intestine.

Answers

Answer 1

Answer:

The process by which the concentration of the glucose in the bag made from small intestine decreased is aerobic respiration.

Aerobic respiration is the process by which cells breaks down glucose in the process of oxygen to release energy for their metabolic needs.

Explanation:

Living things respire, that is they break down nutrients to produce energy for metabolic activities.

The bag made from visking tubing is made of non-living materials which do not respire. Therefore, the glucose concentration in it remains constant. However, for the bag made of small intestine containing living cells, the living cells will carry out aerobic respiration using the glucose molecules found in the glucose solution. During this process, glucose is broken down in the presence of oxygen to release energy for the cells. Therefore, the glucose concentration in the bag will decrease.

Identify the types of point mutations depicted.

Answers

Answer:

The types of point mutation depicted are:

1. C. Silent mutation

2. B. Nonsense mutation

Explanation:

Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.

Silent mutation is known to be the mutation in DNA  whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.

Explanation:

G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.

G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

The immune system is designed to protect against pathogens such as microscopic organisms and foreign substances that arise from outside the body

Answers

Answer:

True.

Explanation:

Protecting against pathogens such as microscopic organisms and foreign substances that arise from outside the body is the role of the immune system.

Answer:

true

Explanation:

Inside your body there is an amazing protectio­n mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system.

When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that's left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates?

Answers

Answer:

Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.

Explanation:

A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.

90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates as it helps to balance the amount of carbohydrates and protein needed for the body to perform its activities.

Carbohydrates

Both carbohydrates and proteins have a vital role in good health. Proteins in our body help to maintain healthy skin, bones, hair and muscles. Carbohydrates give energy to our body parts like the brain, kidney and heart to function properly.

If your diet has only 15% of carbohydrates, then the body will take any measure to get the energy it required for the proper functioning of body parts. The body tries to break down the proteins (that you eat)chemically until it act like carbohydrates.

The statement “ A single-celled organism uses mitosis to create two identical copies of itself” best describes asexual reproduction

The statement which best describes the mode of asexual reproduction is that a single-celled organism uses mitosis to create two identical copies of itself. Thus, the correct option for this question is D.

What is Asexual reproduction?

Asexual reproduction may be characterized as a mode of reproduction in which a new offspring is produced by a single parent. This type of reproduction does not involve the fusion of gametes or a change in the number of chromosomes.

Asexual reproduction is homologous to the process of mitosis. This is because both of them involve the production of two identical daughter cells from a parental cell.

While meiosis produces four daughter cells which are genetically unique to the parent cells. It is the characteristic feature of sexual reproduction that is opposite to an asexual one.

Therefore, the correct option for this question is D.

how can an understanding of the interactions between matter and energy help you understand whether different carbon reservoirs are growing or shrinking?

Answers

Answer:

Carbon reservoirs are shrinking.

Explanation:

the interactions between matter and energy help us to understand and provides information whether different carbon reservoirs are growing or shrinking because when the matter converts into energy, it releases heat energy along with different gases. For example, when volcanic eruption occurs the carbondioxide gas is released in this process which shows that carbon reservoirs are shrinking.

Answer:

By understanding the amount of energy devoted to processes that release carbon versus processes that store it, one can gain an understanding of how the carbon concentrations in different reservoirs are changing.

How do cell differentiation and cell division work together?

Answers

Answer:

After mitosis is over, each of the daughter cells continues its separate life.

Explanation:

One or both can be started or continued through differentiation, ie. processes that give different cells special structures and functions. A cell destined to become a nerve cell moves in one way of differentiation, and a cell destined to be a muscle cell moves in another.

A variation of this mechanism involves a special type of cell called a stem cell. The stem cell divides by mitosis, whereby one daughter cell remains the stem cell and continues to divide again and again, while the other difference in certain cell peaks is determined in the tissues.
