Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller?

Answers

Answer 1

Answer:

Grow

Explanation:

Before every cell division, cells replicate their DNA to pass on to the daughter cells. They also grow in size and replicate their organelles to ensure that each daughter cell has sufficient resources to carry out all the activities necessary for its function. They also ensure there are sufficient nutrients to perform their tasts.

Answer 2

Cells only need to grow in size and contents before each cell division so as to avoid getting smaller in size with successive divisions.

Each of the daughter cells produced during mitotic cell division goes through an interphase period. The interphase period is divided into 3:

G1 phase: a period characterized by cell growth. An increase in size and volume of content is achieved in this stage.S phase: a period characterized by the synthesis of DNA. The amount of genetic materials (DNA) doubles up in this stage, whereas, the chromosome number remains constant.G2 phase: a phase in which protein is synthesized. After this stage, the cell is ready to pass through a period of division.

Without going through the stages above, a cell will simply go into a dormant phase which is essentially a resting phase.

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?

Answers

Answer:

Water molecules will still be able to move across the cell membrane but at a slower rate.

Explanation:

D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:

Answer:

Water molecules will still be able to move across the cell membrane but at a slower rate.

Explanation:

The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

which statement below correctly describes the process of glycolysis?

A. Glucose is broken down into two pyruvate molecules
B. Oxygen and glucose are broken down
C. Two pyruvate molecules are brown down into glucose
D. Glucose is broken down into ATP

Answers

Answer:

A)glucose is broken down into two pyruvate molecules

The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.

What is glycolysis?

Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.

For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.

Therefore, the correct option is A.

Complete the Concept Map to compare the locations and remodeling functions of osteoblasts and osteoclasts, and explain how hormones and physical stress regulate bone remodeling.

Answers

Answer:

The correct answer is attached as an image.

Explanation:

Bone remodeling occurs by the remodeling units osteoblast which is bone deposition and osteoclast which is Bone resorption.

Bone deposition is the process that involves the deposition of minerals in bone tissues which takes place due to the process of osteoblast mainly. the bone deposition is possible in three ways when

- there is an increase in blood calcium.

- there is an increase in mechanical stress.

- decrease in parathyroid hormone

Osteoclast cause the degrade of bone tissue by releasing calcium ion from bone tissue which required opposite conditions than osteoblast that are -

- there is a decrease in blood calcium.

- there is a decrease in mechanical stress.

- increase in parathyroid hormone

A decrease in blood Ca++ concentration causes the parathyroid gland to release PTH, PTH results in osteoclasts to degrade bone tissue which releases Ca++ into the blood. A high level of Ca++, calcitonin results in calcium deposition into the bone.

Bone remodeling involves the processes by which the bone tissue is remodelled by the action of the osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.

Bone deposition is the process by which bone tissues ate mineralized by means of the osteoblast.

Bone deposition occurs through three possible ways:

increase in blood calcium.increase in mechanical stress, and decrease in parathyroid hormone

Osteoclast are involved in the degradation of bone tissue producing opposing effects to that of the osteoblast as follows:

decrease in blood calcium.decrease in mechanical stress, andincrease in parathyroid hormone

The parathyroid gland releases PTH in response to low bllod calcium.

PTH induces osteoclasts to degrade bone tissue which releases calcium ions into the blood.

The increase in blood level of calcium ions induces calcitonin to increase calcium deposition in the bones.

O D. The cuticle protected reproductive structures.

Answers

Answer:

Explanation:

The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.

What is transpiration?

Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.

The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.

To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.

Thus, the correct option is A.

The final price includes the original price paid plus an expected capital gain. The actions of the marginal investor determine the equilibrium stock price. Market equilibrium occurs when the stock's price is -Select-less thanequal togreater thanCorrect 1 of Item 1 its intrinsic value.

We will now look at 3 different situations where we can adapt this generalized model to each of these situations to determine a stock's intrinsic value:1. Constant Growth Stocks;2. Zero Growth Stocks;3. Nonconstant Growth Stocks.Constant Growth Stocks:For many companies it is reasonable to predict that dividends will grow at a constant rate, so we can rewrite the generalized model as follows:This is known as the constant growth model or Gordon model, named after Myron J. Gordon who developed and popularized it. There are several conditions that must exist before this equation can be used. First, the required rate of return, rs, must be greater than the long-run growth rate, g.

Do not round intermediate calculations.$ per shareZero Growth Stocks:The constant growth model is sufficiently general to handle the case of a zero growth stock, where the dividend is expected to remain constant over time. In this situation, the equation is:Note that this is the same equation developed in Chapter 5 to value a perpetuity, and it is the same equation used to value a perpetual preferred stock that entitles its owners to regular, fixed dividend payments in perpetuity. The valuation equation is simply the current dividend divided by the required rate of return.Quantitative Problem 2: Carlysle Corporation has perpetual preferred stock outstanding that pays a constant annual dividend of $2.00 at the end of each year. If investors require an 10% return on the preferred stock, what is the price of the firm's perpetual preferred stock? Round your answer to the nearest cent. Do not round intermediate calculations.$ per shareNonconstant Growth Stocks:For many companies, it is not appropriate to assume that dividends will grow at a constant rate. Most firms go through life cycles where they experience different growth rates during different parts of the cycle. For valuing these firms, the generalized valuation and the constant growth equations are combined to arrive at the nonconstant growth valuation equation:Basically, this equation calculates the present value of dividends received during the nonconstant growth period and the present value of the stock's horizon value, which is the value at the horizon date of all dividends expected thereafter.Quantitative Problem 3: Assume today is December 31, 2013.
