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.
Answers
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.

The paramecium was the only unicellular organism that Stella viewed through her microscope. All the other organisms were multicellular. How was the unicellular specimen different from the multicellular organisms?
Answers
Answer:
The difference between a unicellular specimen and other multicellular organisms will be the NUMBER OF CELLS. See detailed explanation below.
Explanation:
Cells are the simplest and basic unit of life. Living organisms has been classified as unicellular or multicellular depending on the number of the cells that make them up. A unicellular organism is that which possess only one cell to carry out all its life functions. According to the question, the Paramecium is an example of unicellular organism.
On the other hand, a multicellular organism is made up of many cells that specializes to perform the different life functions of the organism. This means that a specific kind of cell carries out a specific life function, this is called Cell differentiation. Examples of multicellular organisms include plants, all eukaryotic fungi etc.
Therefore, Stella's unicellular specimen, which is the Paramecium, will be different from other multicellular organisms in the number of cells possessed by each of them. The unicellular specimen will possess just a single cell while the multicellular organisms will possess more than one cell as viewed by the microscope.

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.
The source of ATP and NADPH, which are required to synthesize glucose, is a
A) light independent reaction: glucose breakdown and carbon dioxide
B) light dependent reaction: electron transport and the splitting of water
C) light independent reaction: electron transport in the splitting of water
D) light dependent reaction: RuBP and the splitting of water
Answers
Answer:
B) light dependent reaction: electron transport and the splitting of water
Explanation:
The source of ATP and NADPH, which are required to synthesize glucose is a light-dependent reaction.
During the process of photosynthesis, light energy is required to tranport electrons that produces ATP and NADPH and splitting of water, generating O2.
Photosystem I (PSI) absorbs the light energy and electrons supplied from PSII (Photosystem II) are transferred to the protein ferredoxin, which further donates electrons to electron transport chain that produces ATP and to the electron carrier NADP+ to form NADPH.
Hence, the correct option is B.

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. The light-independent reaction of photosynthesis would be affected.

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.

Describe the process of mitosis and meiosis.
Answers
Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
The process of dividing the pre-existing cell into two or more daughter cells is called cell division.
Mitosis
Mitosis is defined as the division of the cell in which a single cell divides to form two daughter cells, having the equal number of chromosomes as present in the mother cell. In mitosis cell division, chromosomes duplicate and equally distribute into two diploid cells. Thus as a result, all the daughter cells come to have the same number of chromosomes compared to the mother cell. It occurs in somatic or vegetative cells.
Meiosis
Meiosis is a types of cell division in which a mother cell divides into four daughter cells and each daughter cell having only the half number of chromosomes as compared to mother cell. Meiosis cell division comprises two divisions: Meiosis I and Meiosis II
The meiosis I division is also known as reduction division. This is because it involves the formation of two daughter nuclei with just half number of chromosomes as that present in the another cell. more over, in the prophase stage of meiosis, crossing over ( interchange of chromosome segments between two homologous chromosomes) takes place. This causes the variation in the off-spring and gas a role in evolution.
The meiosis II is also called equational division because the number of chromosomes remains the same in the daughter nuclei as after meiosis I. In this way, four daughter haploid nuclei formed. Then the divison of cytoplasm of the cell ( cytokinesis) takes place and all nuclei get their own cytoplasm and form four haploids.
