What is the main body system that regulates blood glucose levels? How does the human body return blood glucose levels to normal?
Answer:When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal.

What type of anaerobic respiration do humans go through?
Answer:
lactic acid fermentation.
Explanation:
Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
Answer:
The answer for this question is lactic acid fermentation.
Explanation:
When we exercise, we have a lot of lactic acid already built in the muscles. This lactic acid needs to be oxidized into carbon dioxide and water. This is the reason why we start to breathe heavily after a workout session, because since we have a built up of lactic acid, the lactic acid now needs oxygen to be broken down.

Answer:
1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.
4. They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
Explanation:
1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.
The energy stored in the carbohydrates is used in the preparation of chemical energy.
a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.
b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.
2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.
The produced glucose gets converted back into carbon dioxide through the process of expiration.
The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.
3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.
The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.
a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.
4. The process of photosynthesis and cellular respiration have similar molecules as:
In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.

How does competition shape communities?
Answer:
In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.
Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.
In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.
Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.

Do you think it would be a good idea if all the bumper cars in a ride were to move at the same speed? Use Newton's Law of Motion to support your response.
Answer:
Sorry, I didn´t see this one, maybe you already have the answer, if not: Yes, it is a good idea, because it balances the impact forces of every bumper car.
Explanation:
Yes, it is a good idea, because it balances the impact forces of every bumper car.In this phenomenon Newton's Law of motion has been used to prove this incident.
What is Newton's second law?According to newton second law of motion force is always equal to rate change of momentum. S.I unit of mass is Newton.
So, Force basically depend on two factor i.e mass and velocity
In first case if mass is constant and velocity is variable then
Force = mass × acceleration.
And if mass is variable and velocity is constant then it's called thrust force.
Thrust force = Rate change of mass × velocity.
S.I unit of mass is Newton.
Density has been defined as mass per unit volume it means that mass is present in one meter cube.
S.I unit of density is kg/meter^3.
Mathematically
Density = Mass/Volume.
Momentum has been product of mass and velocity. It is a vector quantity and it's S.I unit kg x meter/sec.
Therefore, Yes, it is a good idea, because it balances the impact forces of every bumper car.In this phenomenon Newton's Law of motion has been used to prove this incident.
