The answer is 4. Plants are the number one source of oxygen for us humans. we breathe in oxygen that came from the plants and plants breathe in carbon dioxide from us humans.

The answer is 4. Trees are the one responsible for releasing oxygen into the atmosphere. This is done by way of photosynthesis when plants use energy produced by the sun to produce carbon dioxide and glucose.

The answer is 2. The major source of weight gain in a growing plant is carbon dioxide. Plants take in carbon dioxide in order to convert it to glucose or carbohydrates.

The answer is 1. Photosynthesis is defined as the process wherein producers such as plants or algae produce their food using the sun’s energy by converting it into carbohydrates. From CO2, it is converted to glucose or carbohydrates.

The answer is 2. A chloroplast is the one responsible for producing food for the plant cell. It is considered as one of the parts that are essential to the cell. It is also the one responsible for the process of photosynthesis.

2

The answer is 1. Enzymes are utilized for enhancing the rate of special chemical reactions without being taken up. Enzymes can be like locks and keys wherein an enzyme is like a lock and a substrate is the key and the only way to activate the enzyme is if it is combined with a specific substrate.

1

The answer is 1. According to the data given, we can see that an enzyme when at 37 degrees, has its peak activity as well as with the pH of 8.

The answer is 2. Antibodies function, in general, by directly destroying antigens, starting complement or by initiating inflammation to halt the proliferation of the infectious agent.

2

The answer is 4. WBC is an important factor when dealing with an infection. Once a helper T cell faces a B cell already in contact with an antigen, the T helper cells produce cytokines to help B cells multiply and enlarge other B cells which are of the same features.

4

The answer is 3. Cellular respiration is the process wherein bacteria transform biochemical energy from acquired nutrients into ATP, cabon dioxide and water.

3

The energy connection between glucose and the formation of ATP is that this process happens in cellular respiration. When glucose and oxygen are combined together, they undergo a certain reaction which in turn, creates carbon dioxide and ATP as the result.

In photosynthesis, the source of energy is from the sun. Photosynthesis is a reaction which occurs in plants that convert carbon dioxide into glucose by the help of sunlight.

The energy from the sunlight is converted into chemical energy in order to form glucose or other carbohydrates for the plant’s nutrients.

The process of photosynthesis is important for living things because as we all know plants produce oxygen for us human to breathe in.

Cellular respiration is important in our life because without respiration, necessary tasks would not be performed. The process of cellular respiration is needed to provide energy for us to do things which are needed.

PLOTTING

The chemical X would most likely be insulin. Insulin is a drug or chemical that lowers blood sugar levels for those individuals that do not have or lack the capability of breaking down glucose in order to eliminate it.

insulin

The change in blood glucose level may be due to the effect of food entering the system as it converts to glucose during breakdown.

The relatively constant level of blood glucose is due to the normal state of glucose. The blood sugar levels remain constant because all the excess glucose were already broken down by insulin.

Insulin aids in breaking down glucose. Excess glucose is broken down for energy sources of cells as well as our body in order to do work. Without insulin, glucose builds up and may lead to a disease called diabetes.

Carbon dioxide is essential in our body as it lowers down the pH of the blood. By lowering down the pH, alkalosis is preventable. Carbon dioxide is also needed in exchange for oxygen which is the main source of air for our body.

Lyme disease is transmitted by being bitten by a tick. This tick, called the Ixodes scapularis bites an infected animal which then bites a human afterwards thereby spreading the disease.

The preventive measure taken into action would be if people would routinely check their pets for ticks and other sources of ticks in the house or environment.

Two symptoms that may occur if a person has lyme disease include a skin rash, which does immediately come out after a bite, Headaches, joint pains, muscle aches, and fever may also be experienced. Collectively, these symptoms are called flu-like symptoms.

The danger of ignoring these symptoms and not treating the infection may develop chronicity of the symptoms such as chronic arthritis, problems occurring in the heart and nervous system and in some cases, death.

The answer is 2. According to the data given, the independent variable is the color of the light. The color of the light shown would produce different amounts of CO2 based on the color shown.

2

The problem being investigated in this experiment is to know the amount of CO2 remaining in the container after two days when exposed to different light colors.

The source of carbon used in photosynthesis is the carbon that human breathe out in exchange for the oxygen that plants make. The carbon is released in the atmosphere and is taken up by plants for processing of oxygen in return.

What can be concluded is that enzymes had a reaction on monosaccharides in test tubes 1 and 2 and no reaction on test tube 3. The test tube also had a reaction on disaccharides in test tube 3 and no reaction on test tube 1 and 2.

Effect of pH on enzyme activity

One safety precaution that should be used is the safety of using the materials. The hazards of the materials to be used should be handles with extra precaution. Avoidance of contact in the eyes, for example.

Enzymes are utilized for enhancing the rate of special chemical reactions without being taken up. The effect of high temperature makes the reaction faster but can also kill the enzyme activity in increasing amount of temperature which can also result in death.

A vaccine contains an antigen that triggers a primary immune response to counter exposure to an infectious agent or pathogen. Students still acquire mumps even if they are given vaccines because our body needs to create a memory response after the exposure so that when our body is is exposed again, our immune response would know how to respond and eliminated.

In vaccination, you introduce antigens which create memory cells, formed by the trigger of antigens from a vaccine, to respond to exposure to that same antigen from pathogens in the future.

The student can still acquire other diseases like chickenpox because the vaccine given to the student is indicated for mumps and not for the other diseases like chickenpox.

Guard cells help maintain homeostasis in plants by guarding the water, preventing it from getting out of the cell and maintaining the right amount of water needed in order to survive.
