Tonicity with a high concentration of solutes is said to be hypertonic.
Tonicity is the ability of an extracellular solution to allow the movement of water in and out of the cell by osmosis. The terms hypertonic, isotonic and hypotonic decide the movement of water into or out of the cell.
The hypertonic solution is a kind of solution which has a high concentration of solutes (salts, electrolytes). In Biology, a cell is said to be in a hypertonic solution if the outside solution has a high concentration of solutes than the inside the cytoplasm of the cell. In this situation, there will be a net flow of water out of the cell.
The hypotonic solution is a type of solution which has a low concentration of solute. ). In Biology, a cell is said to be in a hypotonic solution if the outside solution has less concentration of solutes than the inside the cytoplasm of the cell. In this situation, there will be a net flow of water into the cell.
Isotonic solution is one which has the same concentration of water and solutes as inside the cytoplasm of a cell. If a cell is placed in an isotonic solution, there is no net water movement.

describe the effects of altitude and latitude on the distribution of biomes
Answer:
As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.
Latitude determines the amount of sunlight received. The amount of sunlight and the amount of moisture received determines the ecosystem or biome. Biomes are partly determined by altitude. More precisely, biomes are mainly determined by temperature and precipitation, and the altitude can affect both temperature and precipitation. The temperature drops as the altitude increases. This would alter the structure and composition of our biome.
What type of body form of Cnidarians are tubular shaped and attach themselves to a firm surface?
A. polyp
B. medusa
C. nematocyst
D. spicule
The correct answer is Option A: polyp
Polyps are tubular body shapes of cnidarians that are attached to a firm surface.
What are cnidarians?Cnidaria or Coelenterata is a phylum of aquatic animals most of which are marine. Any organism under this phylum is called a cnidarian.These have special cells called cnidocytes (stinging cells) which help to capture prey.Examples of this group are the corals, jellyfish, hydra, sea anemone.Cnidarians have two types of body forms the polyp and the medusa which change during the life cycle of the animal. Some have only one type of body form throughout their life.The polyp is tubular and sessile, usually attached to a firm surface.Medusa (Jellyfish) is bell shaped and motile having tentacles hanging out at the margins.Spicules are sharp needle like shapes embedded in the sponges which help in defense.Nematocysts are large organelles produced as a secretory vessel from Golgi within cells called nematocyte in cnidarians.Learn more about polyp and medusa here:

Which of these is most likely to occur soon after an individual eats a meal?
[tex] \\ \\ [/tex]
=> Your body breaks down carbohydrates quickly, and glucose travels directly through the walls of your intestines and into your blood.
Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.
What does this information best demonstrate?
A.
Cells interact with other cells for regulation and homeostasis.
B.
A hormone is a protein that performs many functions in the body.
C.
Only certain cells can use glucose to produce energy.
D.
Beta cells are not necessary for glucose to be utilized.
The best-demonstrated information is
A. Cells interact with other cells for regulation and homeostasis.
C. Only certain cells can use glucose to produce energy.
One of the important hormones in the human body is insulin. How the human body uses food to meet its energy needs is explained by knowledge of insulin and its workings.
Typically, food-derived glucose that enters the bloodstream is what causes blood sugar levels to rise. The pancreas is a gland that aids in the release of insulin to regulate blood sugar levels. Based on the blood sugar level, insulin often releases itself in a feedback system.
The insulin mechanism best exemplifies the following:
Together with glucagon, insulin contributes to the maintenance of the constant condition known as homeostasis in the human body.Considered essential for cells to use glucose and obtain energy is insulin.As a result, the mechanism of insulin in the human body shows how various cells use energy and how insulin is crucial for preserving homeostasis.

It would happen that the effectiveness of an original vaccine could become less if there was a mutation in the virus that caused the protein spike to change because the antibodies created would not be specific for the new virus.
What would happen to the mutated virus?Vaccines trigger an immune response to fight disease-causing organisms, a mutation in the virus to be fought would change the effectiveness of this immune response, as the specificity would not be the same with the mutant virus.
With this information, we can conclude that The immune response would not be specific for the new virus that caused the protein spike to change.

Elevated levels of which of the following would increase the risk for atherosclerosis,
which could eventually lead to heart attack or stroke?
A. LDL cholesterol
B. HDL cholesterol
C. Statins
D. Insulin
The elevated level of HDL cholesterol would increase the risk for atherosclerosis, which could eventually lead to heart attack or stroke.
The blood flow is obstructed by a buildup of cholesterol plaque in the artery walls. The artery may suddenly become blocked by a clot when plaques burst. Atherosclerosis frequently goes unnoticed until a plaque bursts or the buildup becomes severe enough to obstruct blood flow. Exercise and a nutritious diet may be beneficial. Medication, artery-clearing surgery, and other forms of treatment are available. A CT scan of the heart called a "coronary calcium scan" quantifies the calcium content of the coronary artery walls. Atherosclerosis or coronary heart disease are indicated by calcifications, a buildup of calcium. Hospitals or medical imaging centers may do a coronary calcium scan.

Explain how you would use the number line to solve the following equation. You can write out the fraction names or use the forward slash (/) on your keyboard to represent the fraction bars.
four and two eighths minus two and five eighths equals
a number line from zero to three with a tick on every eighth
subject: science
Answer:
55/8 as a mixed fraction
Explanation:
4 2/8 - 2 5/8 = ?
Four and two-eighths can be represented as a mixed number by multiplying (4x8+2)/8 = 34/8
Two and five-eighths can be represented as a mixed number by multiplying (2x8+5)/8 = 21/8
Then, these two values can be easily added. 34+21 = 55/8
You can plot this on a number line by also representing these mixed fractions as a decimal, and then adding them - you can draw lines to represent the addition process.
Since the number line already represents a tick on every eighth (which is the fraction you would primarily be using), this will make it earlier.

Taigas are in danger as a result of climate change in various ways. The frozen layer below earths surface is partially melting as a result of the warming environment.
More of the taiga is being occupied by muskegs as a result of this water's lack of a drainage system.Deforestation brought on by logging and clear-cutting poses the biggest threat to the taiga. Timber is obtained using these techniques for the production of wood and paper goods. In order to build cities, forests are also destroyed, which might fragment habitats.In boreal coniferous forests, more forest fires are occurring more frequently as a result of global warming.
