Answer:
1. The two main cell types are prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles.
2. Cytoplasm: Cytoplasm contains enzymes that break down waste. It also provides shape to the cell. Cytoplasm enables organelles to remain where they are.
Nucleus: The nucleus controls activity inside the cell. It also carries genes.
Mitochondria: Mitochondria generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate.
Endoplasmic reticulum: The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
Ribosomes: The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make proteins.
Golgi apparatus: A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicles: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another.
Lysosomes: A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Cell membrane: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3. An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
4. Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. These structures include: chloroplasts, the cell wall, and vacuoles.

4. A frog has been brought into the rehabilitation clinic and seems to have reddened
skin. The frog seems to have abnormal posture.
Diagnosis
Treatment
Other symptoms or treatment
Answer:
look for any bleeding or sores. look at the red legs. diagnosis with red leg disease. prescribe antibiotics orally. follow up in a week. meanwhile keep the frog away from other frogs.
Explanation:
To stop a wound from bleeding, platelets in the blood clump together to form a blood clot. The clot dries into a hard scab to protect the wounded area. Underneath the scab, the blood supplies nutrients and oxygen that help new skin cells form. As the skin regenerates, the wound closes.
Which body systems interact with the integumentary system to close the wound?
A. Circulatory and reproductive
B. Immune and circulatory
C. Reproductive and immune
D. Digestive and endocrine
B. Immune and circulatory systems interact with the integumentary system to close the wound.
What is integumentary system?The integumentary system is the body system that protects the body from damage and disease, and helps regulate body temperature. It includes the skin, hair, nails, and sweat and oil glands.
The skin is the largest organ of the body and serves as a barrier against physical, chemical, and biological agents. Hair and nails provide protection and support, while sweat and oil glands help regulate body temperature and moisturize the skin. Additionally, the integumentary system plays a role in regulating the body's water balance, storing vitamins, and sensing touch and temperature.

Which of the following would change the allele frequencies of a population?
A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answer: option B.
B)Mating is random with no selection occurring
Explanation:
This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.
Mating is random with no selection occurring, which would change the allele frequencies of a population.
What would increase the allele frequency in a population?Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.
Thus, option"B" mating is random with no selection occurring.

Which molecules contain only carbon, hydrogen, and oxygen?
Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.

How do ribosomes use mRNA and tRNA to assemble proteins?
Ribosomes are cellular organelles that are responsible for assembling proteins by using messenger RNA (mRNA) and transfer RNA (tRNA).
How do we explain?mRNA is a molecule that contains the genetic code for a protein. It is transcribed from DNA in the nucleus of the cell and then transported to the ribosome.
tRNA is a molecule that carries amino acids to the ribosome. Each tRNA molecule is specific for one amino acid.
The ribosome reads the mRNA molecule and matches the codons on the mRNA to the anticodons on the tRNA molecules. The anticodon is a three-nucleotide sequence on the tRNA molecule that is complementary to the codon on the mRNA molecule.
