Answer:
Genes
Explanation:
Gregor Mendel discovered in his experiments that a factor determined the physical characteristics of an organism. This factor is called a gene. A gene is the molecular unit of heredity in a living organism.
Genes are segments of DNA that holds the information needed to build and maintain an organism and pass genetic traits to offspring. The trait of an organism, which refers to the physical characteristics of an organism, are passed from parents to offsprings via genes. The genes also contain variant forms called ALLELE that determines which trait an organism will possess.

B) Violet and blue light by chlorophyl a and orange, and red light by chlorophyl B
C) Violet, blue, green, and red light by carotene
D) Green, and yellow light by chlorophyl a, chlorophyl B, and carotene
Answer:
B) Violet and blue light by chlorophyl a and orange, and red light by chlorophyl B
Explanation:
Chlorophyll is the pigment present in green plants which is used in the process of photosynthesis by trapping solar energy for use. Chlorophyll comprises of two types namely: Chlorophyll A and Chlorophyll B
Chlorophyll A is known to absorb light in the blue-violet region while chlorophyll B absorbs light in red-blue region. These pigments however don’t absorb green light but they instead reflect it. This makes option C and D invalid. The closest option in their properties is however B.
What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.
Answer:
The body would break down existing muscle to get the amino acids it needs.
Explanation:
If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
What is the function of proteins?Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.
Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.

Sample Response: If the electron transport system did not work, electrons from PSII would not be transferred to PSI. Ferredoxin would then have no electrons to transfer to NADP+ so NADPH would not be produced. This would also affect the light-independent reaction of photosynthesis because NADPH is needed in this reaction. What did you include in your response? Check all that apply. Electrons from PSII would not be transported to PSI. PSI would have no electrons to transport to ferredoxin. Ferredoxin would have no electrons to transport to NADP+. NADPH would not be produced.

In an electron microscope, the sample is bombarded with a stream of electrons that are expelled from an electron gun. The electrons interact with the sample component, the result of which is transformed into an image. Why do you think electron microscopes allow for greater magnification than compound microscopes?
Answer:
It is because the electron microscope uses a shorter wavelength electron
Explanation:
In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.
The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.
Answer:
Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

Categorize Different Foods Categorize the food items below by selecting which macromolecule they are known to contain. apple steak celery olive oil potato avocado egg
Answer:
The correct categorization of the listed food items would be:
Carbohydrate: apple, celery, potato
Protein: Steak, egg,
Fat: Olive oil, avocado.
The four major macromolecules are carbohydrates, proteins, lipids, and nucleic acids.
Foods like apple, celery, and potato are rich in carbohydrates.
Foods like chicken, meat, eggs, et cetera are rich in proteins.
Similarly, foods like olive oil, mustard oil, butter, et cetera are rich in fats or lipids.
Explanation:
Answer: apple- carb; steak- protein; celery- carb; olive oil- lipid; potato- carb; avocado- lipid; egg- protein
Explanation:
Fruit and veggies are mainly made of carbohydrates because that is the storage and structural components they use (think glucose, cellulose, starch, etc.); Steak is a meat, and meat is technically muscle- muscle is built from protein; Olive oil and avocado are lipids because they are considered fats; Egg is protein because it is an animal by-product, and contains many amino acids, which build up proteins.
If the number of photosynthetic organisms on Earth decreased drastically, which would happen as a result? Less water would be available on Earth’s surface. Less solar energy would reach Earth’s atmosphere. More oxygen gas would be found in Earth’s atmosphere. More carbon dioxide gas would be found in Earth’s atmosphere.
If photosynthetic organisms are decreasing on Earth there is no consumption of carbon dioxide, hence option 4 is correct.
How much carbon dioxide Earth’s atmosphere?The amount of oxygen in the atmosphere will likewise decrease as the number of photosynthetic species rises.
More carbon dioxide gas would be found in the atmosphere because forests, especially rainforests, create more oxygen. The development of oxygenic photosynthesis was the most significant metabolic advancement in Earth's history.
It liberated life from the finite supply of reductants drawn from geochemistry and allowed it to create energy and reduce power directly from sunshine and water.
Therefore a decrease in photosynthetic organisms increases the carbon dioxide gas in Earth’s atmosphere.

Light-dependent reactions
Light-independent reactions
Sun's energy absorbed
Sugars produced
Answer:
The question is unclear but I suppose we're to match the stage of photosynthesis with it's description below.
Light-dependent reactions- Sun's energy absorbed
Light-independent reactions- Sugars produced
Explanation:
Photosynthetic process involves two main stages viz: light dependent stage and light-independent stage. In the light dependent stage, light energy from the sun is trapped or absorbed by the Chlorophyll pigment of green leaves. The absorbed energy is used to split water in a process called PHOTOLYSIS OF WATER.
This process (photolysis) releases protons that build up in the thylakoid membrane to produce a proton pump that generates ATP. At the end of the light dependent reactions, ATP and NADPH molecules are produced.
In the light independent stage which occurs in the stroma of the CHLOROPLAST, the ATP and NADPH molecules produced in the light stage are used to power and reduce carbondioxide (CO2) to synthesize sugar (glucose).

Binary fission occurs in which of the following type of organsim?
Answer:
A. Prokaryotes like bacteria
Explanation:
Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).
Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.
