Explanation:

pretty cool we give off what they need and they give off what we need.

What are the resources the human body needs to survive? what role does food play in the human body? what role does water play in

lana66690 [7]

1. The resources the human body needs to survive include food, water, and oxygen. Food includes macro-molecules, as well as vitamins and minerals. Water- can be taken in through foods or drinks, 3/4 of the body is water and oxygen is the air around us is about 20% oxygen and the gas humans need to survive.

2. The role that food play in the human body depends on the type of food; (there are three types of food, carbohydrates, lipids and proteins). Carbohydrates act as a quick source of energy, lipids are long term source of energy, cushioning of organs, and also makes up much of the brain. Proteins mainly build and repair body tissues.

3. The role of water in the human body includes;
Dissolves other materials and allows them to flow in the blood, it gives the cells structure, just the right amount needed to prevent shrinking and exploding, allows food to digest and pass through the intestinal walls in the blood stream, carry waste products out of the body in the urine and regulating homeostasis of body temperature by evaporating and sweating.

4. The role of oxygen in the human body is that it allows human to bur food, creating energy through the process of respiration. Each cell in the body needs oxygen to survive. Cells turn glucose and oxygen into energy (ATP) within their mitochondria through cellular respiration process. Therefore; without oxygen, food can not be processed and energy won't be made.

5. The human body systems that work together to create, process or distribute the body's main power sources include; the digestive system and the cardiovascular system, Food is taken through the digestive system, passes through cardiovascular system for the distribution to all cells where its let into the cells by insulin and processed within the mitochondria. Also the respiratory system and cardiovascular system, Oxygen is taken through the respiratory system, and passes to the cardiovascular system for distribution to all cells, where its processed within the mitochondria. Water goes through digestive system, cardiovascular system and the urinary system to remove wastes and also maintain homeostasis.

6. Personal factors and environmental factors impact the body's ability to survive without air, food or water. Environmental factors include the presence of dangerous animals, temperature of air, humidity of air, presence of protective clothing among others. Personal factors on the other hand include; Fitness level, age, will to survive, amount of fat, genes, metabolism, etc.

Which stage of the eukaryotic cell cycle involves cell growth, synthesis of dna, and preparation for cell division?

AnnZ [28]

Interphase of the cell cycle involves all of those stages, interphase can be broken down into:
G1: for cell growth
S: for DNA synthesis and organelles synthesis
G2: growth and preparation for cell division.

All are included in the interphase phase of cell cycle

After 24 hours, the amount of gas that accumulated at the top of the inverted test tube is measured. The students conclude that

vodka [1.7K]

Attached is an image that wherein the question is being referred from.

There are choices for this question namely:

A- gravity increased the downward ﬂow of the trapped water
B- metabolism of the elodea plants absorbed CO2 from the water
C- heat from the light source caused the escape of dissolved gas
D- light caused the elodea plants to photosynthesize, releasing O2 gas

The correct answer is that light caused the Elodea plants to photosynthesize, releasing O2 gas. Choice A is not true as if gravity increased the downward flow of the water, then the model without light should have air accumulated in the test tube too. In Choice B, while it is true that the plant may have absorbed the dissolved CO2 in water, this does not explain why there is gas on top of the test tube. Choice C may only evaporate the water, not cause the escape of dissolved gases. In choice D, however, light caused the Elodea plants to perform photosynthesis releasing O2 gas compared to the other model without light wherein the plant cannot perform photosynthesis thereby not releasing O2 gas therefore no gas is seen on top of the test tube.
