What is Science??​

Answer:

Hunting

Explanation:

Camouflage is a hereditary physical aspect, whereas hibernation and migration are instinctual. Hunting is a learned behavior as it is not as ingrained as the other two and is not automatically done.

P.S. at first I read the answer choices to the tune of "O, christmas tree"

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.

Answer:

Glucose and oxygen is produced

Explanation:

oxygen is usually released as a by-product and the glucose made is converted to starch and stored in leaves

plus ATP molecules are formed from excess light energy and is converted to a high energy chemical compound

Hypothesis:

As the tomato plant grows, nitrogen levels in the soil will decrease

A hypothesis showing the effect of nutrients in the soil on the growth rate of the tomato plant is As the tomato plant grows, nitrogen levels in the soil will decrease.

The  soil is  a mixture of different components which comprises  minerals, organic matter, and living organisms, it is a loose sediment,  Moreover, there are different types of soil like Clay Soil, Sandy soil, Loamy Soil, Silt Soil

soil  it is One of the most crucial components of the biosphere, this particle is composed of 45% minerals, 50% spaces  and 5% organic matter, the soil involve in  many important functions such as Providing a growth medium for the plants, Acts a modifier of the earth’s atmosphere

The formation of soil involve in different process , it can be formed   by weathering of rocks and the weathering of Solid rock  occur in three way like Mechanical Weathering, Chemical Weathering, Biological Weathering

Water is attracted to the sides of a glass cylinder is an example of cohesion.

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion.

Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Answer:

to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Explanation:

Firstly, let us calculate the number of calories burnt in 2 hours

in 10 minutes; 30 calories are burnt

∴ in 1 minute 30/10  calories are burnt = 3 calories are burnt

2 hours = 120 minute

∴ in 120 minutes 3 × 120 = 360 calories are burnt.

Next, let us calculate the amount of trail mix that contains 360 calories

100g of trail mix = 450 calories

450 calories = 100 g

1 calory = 100/450

∴ 360 calories = 360 × (100/450)

=  360 × 0.222 = 80g

∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

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.

2. Psychological stress: This stress can be caused by emotional and cognitive factors. Rigorous deadlines and expectations from bosses can lead to emotional drain.

Answer:

Stem tuber ---- Potato

Conditioned reflex ---- Pavlov's experiment

Blood circulation ---- William harvey

Pancreas ---- Insulin

Autotrophs ------ Blue green algae

Active transport ---- Minerals

Note: Chlorosis has no matching item in the list. Explanation is given below.

Explanation:

Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.

Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's  performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.

William Harvey discovered the circulation of blood and the function of the heart .

The islets of Langerhans found in the Pancreas secretes the hormone, insulin.

Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.

Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.

Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.

Answer:

3. convection resulting from temperature and pressure differences above land and water

Explanation:

Due to the the difference between the ability of land and to water to absorb and radiate heat energy, the land gets heated up by the sun more quickly than water during the hot afternoons. As a result, the air above the land surface gets heated up more quickly than that above water. Warm air being less dense than cold air will rise above to atmosphere creating a low pressure area on land. On the other hand, air above water is not heated up as quickly, thus the dense cooler air over water will rush in and replace the warm air that has risen above the land surface.

At night, the land cools off more easily than water, hence the air above the land surface is cooler. On the other, water does not lose heat as quickly as the land, hence the air above the water surface is warmer than that over land. Warm air over the water surface will rise above, while colder air from land will replace it.
