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.

To answer the question what is 77800000 in scientific notation let’s recall how to convert 77800000 to scientific notation as detailed on our home page.

When you split the number 77800000 into a coefficient and a power of 10 you do get 77800000 in exponential form, but there is an indefinite number of possibilities.

As you probably want 77800000 in normalized scientific notation, the coefficient or significand of 77800000 in scientific notation must be in the interval [1,10[.

As there are many ways to express 77800000 in scientific notation, in this post we mean 77800000 in normalized scientific notation, unless stated otherwise. Therefore:

77800000 in scientific notation = 7.78 × 107.

Answer:

yoo im just now learning about this

i think u just move the decimal right? so it would 7.8 with a power of 10^7?

Explanation:

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.

Explanation:

Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.

The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.

The ground tissue of cactus has many parenchyma cells that store water.

Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.

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.
