You now find new cells which contains 200 mM CaCl2 and 15 mM glucose. The cell membrane is permeable to Ca ions, impermeable to Cl- ions, impermeable to Na ions and impermeable to glucose. You transfer these cells into a solution which has 140 mM (NaCl) and 150 mM glucose. What happens to the cells after the solution and cell have come to equilibrium

Answers

Answer:

The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.

Explanation:

The concentration of CaCl2- = 200mM

CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity

The concentration of glucose = 15 mM

So, the osmolarity of solution 1 would be:

3 × 200 + 15= 615 mM

Similarly, the osmolarity of the second solution would be

The concentration of NaCl = 140 mM

The concentration of glucose = 150 mM

NaCl dissociates in the two different ions in a solution and each has the same osmolarity

140×2+ 150= 430 mM

The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.

Answer:

1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.

2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.

3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.

Answers

Answer:

Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

What is vertebrate?

Vertebrate is defined as any terrestrial animal, which is the most prevalent subphylum of the phylum Chordata. Vertebrate animals are those that have a backbone. There are many vertebrates on the planet today, and they are divided into 7 classes according to their physiological and anatomical characteristics.

Stem cells are defined as unique human cells that can differentiate into a wide range of cell types, from brain cells to muscle cells. Stem cells can differentiate in the body into a wide range of various cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.

Thus, the stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.

Why postharvest physiology is important to maintain sustainable food supply on this planet. Please give named examples and discuss various biological factors associated with produce deterioration after harvest

Answers

Answer:

Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption

Explanation:

Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.

Carnivores eat the meat of other animals. Example: Bear

Herbivores eat vegetation. Example: Deer

Omnivores eat a combination of both meat and vegetation. Example: Humans

Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon

Detritivores eat small bits of organic matter, such as soil. Example: Worms

Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.
