Answer:
What is a macrocolecule?
A biological macromolecule is a very large molecule that is built from smaller biological, or organic, molecules that are linked together by covalent bonds.
Macromolecules are necessary for an organism’s growth and survival
There are four major classes of biological macromolecules. Carbohydrates, Proteins, Fats, and Nucleic acids (DNA and RNA)
What do you notice about the atoms that make up these molecules?
Carbs-They contain carbon, hydrogen, and oxygen and include the sugars, starches, and fibers that are found in grains, fruits, and vegetables.
Carbohydrates are important for brain function, and they provide energy for working muscles and the central nervous system.
Protein- This type of macromolecule can be found in meats, poultry, fish, eggs, dairy products, nuts, and legumes.
Protein is necessary for building and repairing muscle mass, and it helps maintain a healthy immune system.
There are about 20 amino acids,most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.
Fats-are used by the body as energy and to store fat-soluble vitamins (vitamins A, D, E and K). They also insulate the body and protect vital organs.
The human body stores excess fat in specialized cells called adipocytes.
consists of two main components—glycerol and fatty acids.
What happens to macromolecules from food during digestion?
Glycolysis can be best explained as a series of chemical reactions that extract energy from glucose. This process occurs in liver cells. At the start of glycolysis, a molecule of glucose (C6H12O6) is trapped and destabilized, or broken down into two three-carbon molecules. These molecules are called pyruvate. The net products of the process are two molecules of ATP—four molecules of ATP are actually produced, but two are used up—and two molecules of NADH. The liver also metabolizes other macromolecules,
If there is not enough carbohydrate intake, how does the body form glucose?
When there is a shortage of fats or carbohydrates, proteins can also yield energy.
Fats typically provide more than half of the body's energy needs.
If not enough protein is provided by the diet, the body starts chewing on muscle cells.
If there is a glucose shortage, how does the body produce energy?
glucose can be made in the liver and kidneys using protein from elsewhere in the body.
What atoms make up sugar molecules, amino acids, and fatty acids?
Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat

Mitosis and meiosis are cell division mechanisms that lead to different numbers of daughter cells. Which explanation best describes how these two processes maintain continuity?
meiosis :cell division that produces reproductive cells in sexually reproducing organisms
mitosis:cell division in which nucleus divides into nuclei containing the same number of chromosomes
meiosis nucleus divides twice and produces 4 daughter cells which are not genetically the same
mitosis necleus divides ones and produces two daughter cells which are genetically the same

Explanation:
A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below.
Graph shows heat, measured in Joules, radiated from an aquarium over time, measured in seconds. At 0 seconds, the energy, in the form of heat, is 1.2 Joules. At 5 seconds, the energy is 1.6 Joules. At 10 seconds, the energy is 1.3 Joules. Finally at 15 seconds, the energy is 1.5 Joules.
Based on this data, he concludes that the aquarium cannot be considered a closed system for this experiment. Explain why this conclusion is invalid.
A closed system exchanges both matter and energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system can exchange energy but not matter with its surroundings, and the scientist did not measure the movement of matter.
A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system exchanges all of its matter with its surroundings, and the scientist did not measure the movement of matter.
Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

The opening and closing of the heart valves is caused by Multiple Choice action potentials within the cusps of the valves. pressure changes of alternating contraction and relaxation during the cardiac cycle. contraction and relaxation of papillary muscles that pull on heart strings. contraction of the smooth muscle in the walls of the great vessels leaving the heart.
Answer:
pressure changes of alternating contraction and relaxation during the cardiac cycle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Hence, the opening and closing of the heart valves is caused by pressure changes of alternating contraction and relaxation during the cardiac cycle.

Chieko is doing an experiment with a water clock. She fills a 2-liter soda bottle with water and marks the water level. She puts two tiny pinholes in the base of the bottle. Water seeps out. She checks the time against her watch. After an hour, she marks the new water level. She repeats this process until the water is all gone. Chieko made six hour marks on the bottle, representing the passage of six hours. How can Chieko test her water clock to see if the timing is accurate?
Group of answer choices
Repeat the experiment using a better watch
Repeat the experiment using less water in the bottle
Repeat the experiment using a kitchen timer set to go off each hour
Repeat the experiment using the same amount of water and the same watch
