Answer:

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.

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

Answer: The stem, the stem keeps the plant stable. Much like our skeletal system.

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

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.

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.

The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Mouth - break down food mechanically and chemically

Salivary Glands - produce saliva that contains enzymes which chemically break down food

Esophagus - move food from mouth to stomach through a process called peristalsis

Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles

Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients

Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets

Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate

Small Intestine - absorbs nutrients from chyme

Large Intestine - absorbs water and dries out food, turning it into waste

Rectum - stores waste before it leaves the body

Anus - an opening where waste exits the body

Answer:

i think it's March

Explanation:

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:

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).
