what step of cellular respiration requires oxygen?
Answer:
Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.
The step of cellular respiration requires oxygen include the following:
Pyruvate oxidationCitric acid cycleOxidative phosphorylationWhat is Cellular respiration?Cellular respiration involves the conversion of chemical energy from food
into ATP which is needed for the cell's daily activities.
It also involves series of reactions and pathways to ensure adequate
conversion and utilization of resources available. The reactions listed
require the presence of oxygen for them to occur in body cells.

What will be happen when cell placed in hypertonic solution?
(1) Shrinking of cell
(2) Swelling of cell
(3)No changes in size
(4) Endosmosis
Answer: If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Image credit: Mariana Ruiz Villareal.

Why is osmosis important to
the survival of a cell?
Answer:
The most important function of osmosis is stabilizing the internal environment of an organism by keeping the water and inter cellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This is very essential to the survival of a cell.

How does the molecule C6H12O6 enter our body
Glucose has the formula C6H12O6. It's an essential source of energy for aerobic and anaerobic cellular respiration in all organisms. Glucose enters the body as galactose, fructose, lactose, sucrose, or starch.
What are the sources of glucose for body?Glucose is a molecule that consists of six carbon atoms and has the chemical formula C6H12O6. It is a source of energy that may be found in every organism on the planet and is necessary for aerobic as well as anaerobic cellular respiration to function properly. Glucose typically enters the body in the isometric forms of galactose and fructose (monosaccharides), lactose and sucrose (disaccharides). Glucose can also enter the body in the form of starch (polysaccharide).
When we go without food for an extended period of time, our body releases glucose that was previously stored as glycogen, which is a polymer of glucose. Through a process known as gluconeogenesis, glucose can also be produced from the byproducts of the breakdown of fatty acids and proteins.

which enzyme is part of the electron transport chain in many aerobic bacteria
Answer:
cytochrome c oxidase is the answer
The enzyme cytochrome c oxidase or complex IV is found in the electron transport chain of the plasma membrane in many aerobic bacteria.
What is cytochrome c oxidase?It is an electron transfer enzyme, which contains iron and is involved in cellular respiration that is located in the plasma membrane of bacteria.
This is the final complex of the electron transport chain, which catalyzes the oxidation of cytochrome c by transferring its electrons to oxygen.
Therefore, we can conclude that the enzyme cytochrome c oxidase or complex IV is found in the electron transport chain of the plasma membrane in many aerobic bacteria.

Protecting marine life from overfishing is a type of sustainable practice and is therefore denoted as option D.
What is Sustainable practice?These are the activities which are required for the maintenance and preservation of the qualities which are present in the environment and examples of such qualities include air, animals etc.
This type of practice also ensures that the activities done by humans don't affect other components of the ecosystem in a negative manner. Special attention is paid to the adverse effects which could occur such as extinction, pollution etc thereby averting them.
In this scenario, protecting marine life from overfishing helps to prevent extinction of the species which is therefore the reason why it is a sustainable practice.

Why are Gamma Ray's the most dangerous of all electromagnetic waves?
Answer:
The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous.

Which of the following describes when the cell leaves the cell cycle and no longer divides?
(1 point)
O interphase
O senescence
o differentiation
O mitosis
When the cell leaves the cell cycle and no longer divides, it enters the quiescent phase.
The quiescent phase is also known as G0 phase. It is a phase in the cell cycle where cells that have no need to divide enter a perpetual resting phase until they are signalled to divide.
Once they get a signal to divide, they move from the G0 phase to the G1 phase and then proceed normally with the cell cycle. For example, cells of the neurons in humans have no need to divide unless on special occasions. Such cells stay in G0 phase perpetually.

What type of energy is coming into the food web?
Answer:
The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants.

how parrotfish affect the carrying capacity of coral reefs
Answer:
Explanation:
Parrotfish spend 90% of their day cleaning the reef of algae. This cleaning (eating) helps corals grow and thrive, and healthy reefs support more fish in the sea. ... They snack on the hard parts of coral which becomes a white sandy material in their stomachs that they leave behind on the reef.

Explanation:
DNA carries the cell’s genetic information; however, it cannot leave the __________________. Because of this, it copies part of its nucleotide sequence into a complementary copy of ______________ during the process called _____________________. During this process, ___________Polymerase separates the DNA strands. It then uses one strand of DNA as the __________________ from which nucleotides are assembled into a strand of RNA. Each three letter sequence on the mRNA is called a ______________. The start codon is ____________ and the three stop codons are _____________, ____________, _____________. Once the mRNA leaves the nucleus it goes to the ____________________ to prepare for protein synthesis which is called ___________________. During this process, a ______________ molecule brings the _________________________ to the ribosome. The amino acids are hooked together by ____________________bonds. The tRNA is able to match up to the mRNA by its _______________________. When the stop _________________ is reached, the __________________ chain is released into the ______________________.

A certain DNA molecule contains 22% of the nitrogenous base Adenine. What complimentary base would be found to bind to Adenine and what concentration would the base be measured in when studying the molecule?
Answer:
Adenine would pair with complimentary base thymine and have a concentration of 22%.
Explanation:
Since purines pair with a pyrimidine, adenine would have to pair with either cytosine or thymine. Cytosine only binds with guanine leaving thymine. Since thymine pairs with adenine, there must be equal amounts in the molecule, therefore it is 22%.

All of the following will help the skin to fight infection but one. Which of the following will have little effect on the skin's ability to fight infection? Group of answer choices More tight junctions between keratinocytes of the stratum corneum. Greater production of melanin. Increased secretions of defensins from skin cells. Greater production of keratinocytes resulting in more layers of the stratum corneum.
In order for the skin to fight off infection more efficiently and of the options listed, the correct choice would be for the skin to secrete more defensins.
Keratinocytes are the cells that constitute the epidermis. They are the most dominant cell type in this region and function to create and maintain this barrier. Though this barrier that they create does in fact aid in avoiding bacterial infection, it does little to fight off an already existing infection.
The correct answer is for the skin cells to secrete a greater number of defensins. These are small cationic proteins which are known as "Host Defense Peptides". What this means is that these defensins will either have direct anti-infection properties, or they will act as signals for the immune system.
