Answer:
The two types of stressors are;
1. Physical stress
2. Psychological stress
Explanation:
Stress is a state of subjecting a person or thing to different forms of pressure. Stressors are factors that can lead to stress. When a person gets into an institution of higher learning or begins working with an establishment, he can face different kinds of stress. Two of them include;
1. Physical stress: This stress could be caused by excessive exertion in activities. In the school environment, attending lectures, completing assignments, and engaging in social activities could result in burn out.

Describe the importance of a hypothesis in scientific inquiry.
Answer:
The fundamental concept of a theory is that there is no predetermined conclusion. A main feature of this phase of the experimental process is deriving conclusions from theories regarding the outcomes of possible studies and then conducting certain experiments to see if the predictions are supported.
Explanation:
A hypothesis is crucial in scientific inquiry as it serves as a testable and falsifiable explanation or prediction for a specific phenomenon or observation.
It provides a structured approach to investigating a research question and guides the design of experiments and data collection.
By formulating a hypothesis, researchers set a clear direction for their study and establish a basis for drawing conclusions based on evidence.
If the hypothesis is supported by data, it strengthens the understanding of the subject matter.
Alternatively, if the data refute the hypothesis, it encourages further exploration and refinement of scientific knowledge, promoting the advancement of understanding and discoveries in various fields.

Answer:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water
Explanation:
please give brainliest
Answer:
Water covers about 71% of the earth's surface.
326 million cubic miles of water on the planet
97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling).
320 million cubic miles of water in the oceans
3% of the earth's water is fresh.
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
0.5% of the earth's water is available fresh water.
If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon).
In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.
This supply is continually collected, purified, and distributed in the natural hydrologic (water) cycle.

What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

Explanation:
Hanan ate a meal that consisted of rice, dal, fish and fried potatoes. Explain the process of digestion of the food with reference to the parts and enzymes involved in the digestive system.
Answer: A digestive system can be defined as a system which is made up of the alimentary canal and the associated glands and organs which produce some of the enzyme- rich secretions that bring about digestion. The process of digestion of food Hanan are, is discussed below.
Explanation:
The food taken by Hanan consist of carbohydrates (rice, potatoes ), protein( fish, dal) , fats and oil( fish, fried potatoes). The digestion of the food taken passess through a long tube ( alimentary canal) which stretches from the mouth through oesophagus to stomach, intestines and down to the anus.
In the MOUTH, the following occurs:
--> The food is cut and grinded into smaller pieces by the help of the teeth.
--> the enzyme ptyalin acts on the carbohydrate part of the food converting it to complex sugar.
--> the food is mixed with saliva, with the help of the tongue, is rolled into a bolus which is then swallowed.
At the STOMACH, food enters through the peristaltic movements of the oesophagus, The following occurs:
--> The muscular walls of the stomach contract and relax forcefully, thus churning the food.
--> Gastric juice( consists of pepsin, renin and dilute hydrochloric acid). Dilute hydrochloric acid activates pepsinogen to pepsin which digests proteins to polypeptides.
--> Food remains in the stomach for three to four hours. By this time, it is a thick, creamy fluid called chyme which them moves to the duodenum (small intestine).
At the SMALL INTESTINE, digestion occurs at the first part called the duodenum, and later part called the ILEUM.
--> Several substances are secreted into the duodenum from the pancreas( pancreatic juice) and liver( bile), the accessory organs of digestion.
--> pancreatic juice contains three important enzymes whose activities include:
• Amylopsin: Breaks down complex sugar to maltose
• Trypsin: breaks down protein into peptides
• Lipase: Breaks down fat into carboxylic acids and glycerol (end product of digestion of fat).
--> Bile from the liver, adds water to the chyme, emulsifies fat and neutralise the action of dilute hydrochloric.
At the ILEUM, intestinal juice is produced by special cells of the small intestine. Their actions include:
• maltase: this acts on maltose converting it to glucose( which is the end product of carbohydrate digestion).
• erepsin: This acts on peptides converting it to amino acids( which is the end product of protein digestion).
Absorption takes place at the small intestine.

how are karyotypes made?
Answer: A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.
Explanation:
Karyotypes are prepared from mitotic cells that have been arrested in the metaphase or prometaphase portion of the cell cycle when chromosomes assume their most condensed conformations. A variety of tissue types can be used as a source of these cells.
