conduction of heart beat
Answer:
Explanation:
The cardiac conduction system are specialized cardiac muscle cell that are located in the walls of the heart and sends signals to the heart muscle. These signals cause the heart to contract.

An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function? A. cell membrane B. cytoplasm C. nucleus D. vacuole
Answer:
A. Cell membrane
Explanation:
The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.
The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.
Thus, the correct answer is option (A).
Answer:
A. cell membrane

Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

What important soil function does soil structure influence ?
Answer:
A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!

Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure
(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it
Explanation: Plato, you're welcome
(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

How are fats used in living things?
Answer:
- store + transmit genetic information

Explanation:
Jonathan designed an experiment to plant lima bean seeds. His variable was to change what kind of light each plant received. He
used a different kind of light with each plant. He hypothesized that the plant grown under the plant light would have the greatest
amount of growth. Did the data support the hypothesis? Explain.
Answer:
Yes, it was.
Explanation:
The data did support the hypothesis because the data given was generalized on the change of light each plant received. The hypothesis was that the plant light would have the greatest amount of growth. The data was the different light types and the hypothesis was which one he inferred would work best.
Answer:
- The type of plants used in the study
- The number of plants in each experimental group

1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell
