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.
The answer would be:
Platelets stick to the damaged area of a blood vessel and help seal the break.
Platelets are blood cells that play a role in blood clot formation. It also helps with blood vessel repair. The process by which platelets stick to the damaged area of a blood vessel is called adhesion. When platelets stick to the damaged blood vessels they release chemical signals to attract more platelets to the site of injury
Answer:
5,2,3,1 and 4.
Explanation:
Whole genome shotgun sequencing is the method in the genetics that are used to sequence the whole DNA fragments. Different DNA sequencing methods are chemical sequencing and Sanger sequencing.
The different steps that are involved in the whole genome shotgun sequencing are as follows. The DNA is isolated and broken DNA with the help of the restriction enzymes. The genomic fragments are inserted into the cloning vector for its multiplication. These fragments are then transformed into the E.coli with the cloning vector. The sequence assembly is important step in the sequencing. Than the sequencing of the cloned fragments are done to find the sequence of the whole genome.
Thus, the correct sequence is 5,2,3,1 and 4.
Search results: Many bacteria are resistant to common antibiotics. This means that the drug can't kill the bacteria. Sensitivity analysis is a useful tool to help quickly determine if bacteria are resistant to certain drugs.
Answer:
It would make it possible to compare that species to other species at a level deeper than outward appearance
Explanation:
The proteins like hemoglobin and enzymes can be studied to see whether organism which are similar in form can also be related to each other. Its differences found in these proteins' amino acid sequences will present how closely or distantly related an organism is to another.
