In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.

Answers

Answer:

isotonic; the same rate

Explanation:

Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.

For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

What evidence from the study supports the hypothesis that dogs might use a magnetic sense to navigate?

Answers

Answer:

Yes.

Explanation:

Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.

During the Krebs Cycle, high-energy electrons and hydrogen ions are transferred to carrier molecules to form NADH and FADH2. What are the two other molecules released during the Krebs Cycle?

Answers

Answer:

During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2. ATP NAD+ NADH Citric acid is broken down into a 5-carbon compound, then into a 4-carbon com- pound. Along the way, two more molecules of CO2 are released, and electrons join NAD+ and FAD, forming NADH and FADH2.

Explanation:

Answer:

The Krebs cycle uses pyruvic acid from glycolysis to produce carbon dioxide, NADH, ATP, and FADH2.

ATP Citric acid is decomposed into a 5-carbon compound, which is subsequently decomposed further into a 4-carbon compound.

Along the way, two additional molecules of CO2 are released, and electrons join NAD+ and FAD to form NADH and FADH2.

Label each of the following structures or processes.

Answers

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

I think that part is a mitochondrion, in which:

The process that the mitochondrion performs is that it generates energy for the cell (also known as the powerhouse of the cell).

The two raw materials the mitochondrion needs are oxygen and a precursor of some sort, whether is be sugar or carbohydrates.

The molecule generated by the mitochondrion is called ATP, or adenosine triphosphate, this molecule is important because it allows the cells to work and function, ultimately resulting in the organism being able to live.

Also btw mitochondrion is singular and mitochondria is plural.

Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.

Answers

Answer:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

Explanation:

An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.

So, an example of this applied to bacteria or viruses could be:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.
