When a person is sprinting the person's muscle cells will begin using anaerobic respiration in addition to keeping the mitochondria respiring aerobically as much as the oxygen supply will allow.
What benefits do muscle cells gain from anaerobic respiration in this situation?
A. The mitochondria can use the oxygen generated as a waste product during lactic acid fermentation to increase their output of ATP
B. When pyruvate is transformed into lactic acid, four more ATP molecules are produced that can power muscle movement while NAD is regenerated
C. For every glucose molecule that enters glycolysis, the cell generates, without oxygen, two ATP molecules that can keep the muscles moving.
D. Adding electrons from NADH to pyruvate regenerates NAD, so that glycolysis can continue, and produces lactic acid a waste product that can diffuse out of the cell.
Answer:
Adding electrons from NADH to pyruvate regenerates NAD, so that glycolysis can continue, and produces lactic acid a waste product that can diffuse out of the cell.
For every glucose molecule that enters glycolysis, the cell generates, without oxygen, two ATP molecules that can keep the muscles moving.
Generally,Glycolysis, takes place in the cytosol of cells with or without oxygen.Therefore it continuous mechanism should be in place during anaerobic respiration for supply of 2ATPs from the Net of 4 ATPs when pyruvate is formed, to ensure sustenance of energy.
Therefore,in this athlete, it is imperative to ensure continuous mechanisms of Glycolysis by constant availability of Co-enzyme NAD+ which must be reduced so that electrons can be available for the substrate phosphorylation steps for generation of pyruvate and ATPs.
Thus as the lactic acid is formed from the pyruvate,it is easily removed from the body as wastes, instead of retaining by the muscles cells. The lack of oxygen ensure supply of of 2ATPs for sustaining the athletes in the anaerobic condition.

Which of the following types of membrane is associated with the skin?
A. Peritoneum
B. Synovial
C. Serous
D. Cutaneous
Answer:
the answer is D. Cutaneous
Explanation:
The cutaneous (ku-ta'ne-us) membrane is your skin. Its superficial epidermis is composed of a stratified squamous keratinizing epithelium. The underlying dermis is mostly dense (fibrous) connective tissue. Unlike the other epithelial membranes, the cutaneous membrane is exposed to air and is a dry membrane.
The type of membrane that is associated with the skin is cutaneous. Therefore, option (D) is correct.
What is cutaneous membrane?Cutaneous membrane is a type of epithelial membrane that covers and protects the external surface of the body, including the skin, hair, and nails. The other options mentioned are different types of membranes found in the body.
Peritoneum is a serous membrane that lines the abdominal cavity and covers the abdominal organs. Synovial membrane is a connective tissue membrane that lines the cavities of freely movable joints.

What ions are formed when sodium chloride is dissolved in water
Proteins accomplish many cellular tasks such as facilitating chemical reactions, providing structure, and carrying information from one cell to another. How a protein chain coils up and folds determines its three-dimensional shape. Its shape will, in turn, determine how it interacts with other molecules and thus performs its function in the cell.
Answer:
True.
Explanation:
Protein is a very versatile molecule and extremely important for the efficient functioning of the organism. However, proteins can only perform their functions through chains that wind and fold to form three-dimensional structures. these three-dimensional structures are the active form of the protein because they build the active site that will allow the substrate needed for body functions to fit and be catalyzed as needed.
In other words, the protein needs to be in its three-dimensional form for the construction of the active site to take place.
What is the most likely pathway for root cells to obtain energy and identify the organelles involved
Answer:
By breaking down glucose made in photosynthesis with the mitochondria.
Explanation:
Root's cannot undergo photosynthesis but sugar can be transported to the roots through the phloem. Once sugar gets to the root cells, cellular respiration can break down sugar into energy. Cellular respiration starts with glycolysis which occurs in the cytoplasm but the process completes in the mitochondria.
Cells in the roots of plants get their energy through a vascular transportation system within the plant by vessels called phloem.
The energy is produced through photosynthesis and converted to useable energy form by cellular respiration.
Plant veins transport water, nutrients, and energy to the rest of the plant. Plants absorb water and nutrients through their roots and make glucose and transport energy, they use their vascular system to move the water and nutrients up into the rest of the plant and to the roots from leaves.
Plants cells convert light energy or radiant energy to glucose which is transported to the various parts of the plant to provide it as fuel for their functions with help of chloroplast.Phloem is one of the vessels that helps in the transportation of sugar or glucose from leaves to the rest of the plant body including roots.In roots, these glucose molecules are converted to ATPs by the process called cellular respiration within the mitochondria.Thus, the correct answer is - veinous transport system.

Which of the following are correct regarding carbohydrates? SELECT ALL THAT APPLY They are the preferred energy source of cells. Polysaccharides are long chains of glucose molecules. They are hydrophilic. They contain energy in carbon–carbon bonds.
Answer:
They are the preferred energy source of cells.
Polysaccharides are long chains of glucose molecules.
They are hydrophilic.
They contain energy in carbon–carbon bonds.
Explanation:
Carbohydrates are one of the four biomolecules found in living systems. They are molecules made up of carbon, hydrogen and oxygen in their structures. A monosaccharide is the simplest unit of a carbohydrate. Carbohydrates are energy sources since they store energy in their chemical bonds i.e. carbon-carbon bonds.
They are preferred as energy sources by cells due to the fact that their stored energy can be released quickly for use by cells i.e. easily broken down compared to lipids.
Polysaccharides (large chains of carbohydrate) such as starch etc. are composed of long chains of monosaccharide units such as glucose. Due to the hyroxyll group in the structure of carbohydrates, they are considered water-loving or hydrophilic.

Three students attempt to define what a circle is. Can you match the teacher's comments to the definitions?
This question is incomplete, the complete part of the question containing the students definition and teacher's comment is:
Ruby's definiton: A 3-dimensional shape whose boundary consists of all points equidistant from a fixed point (the center).
Shriya's definition: The set of all points in a 2D plane such that for every point in the set there is exactly one other point in the set that is d (call it diameter) units away.
Abhishek's definition: The set of all points in a plane that are the same distance (radius) away from some given point (center).
Teacher's comments:
Are you thinking of a sphere?
You are correct. Nicely done!
This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle.
THE ANSWERS ARE:
Ruby's definiton: Are you thinking of a sphere?
Shriya's definition: This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle.
Abhishek's definition: You are correct. Nicely done!
Explanation:
A circle is a two-dimensional round plane shape (2D shape) whose boundary line called the circumference has several points that are of the same distance (radius) from the centre point of the shape.
Based on this definition of a circle, the answers given by each students will now be reviewed.
1). Ruby's definiton: This definition is wrong because a circle is not a 3D shape. The definition is describing more of a SPHERE, which is a 3D round shape in a space. Hence, the teachers comment will appropriately be; Are you thinking of a sphere?
2.) Shriya's definition: This definition is wrong because it is not describing a circle, rather it is describing a part of a circle (diameter). Hence, the teachers comment appropriate for this answer is: This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle
3). Abhishek's definition: This definition correctly describes a circle, hence, the teacher's comment will be: You are correct. Nicely done!

Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).

According to the mantle plume theory what causes hot spots?
Answer:
According to the mantle plume theory, Plumes are proposed to ascend through the mantle and start to incompletely dissolve on arriving at shallow profundities in the asthenosphere by loose melting.
It leads to enormous volumes of volcanic eruption. The plumes hypothesis suggested that this dissolved magma ascends to the surface and emits to shape "hot spot". the plume head liquefies partially on arriving at shallow profundities, a plume is frequently invoked as the reason for the hotspots at particular region, for example, Hawaii or Iceland.
What experimental evidence supports the fluid mosaic model of biomembranes?
Answer:
There are many experiments available: Freeze-fractue experiment is one of them.
Explanation:
The fluid property of functional biological membranes had been determined through labeling experiments, x-ray diffraction, and calorimetry.
experimental evidences for the "mosaic" and "fluid" property of layers of mosaic fluid model -
- Freeze-fractue experiment the layer and watch protein.
- An significant experiment that gave proof supporting liquid and dynamic natural was performed by Frye and Edidin.
-They utilized Sendai virus to drive human and mouse cells to combine and create a heterokaryon and showed that proteins of both human and mouse remains segregated to isolate parts of the heterokaryon a brief time frame after cell combination. However, the proteins inevitably diffused and after some time the outskirt between the two parts was lost.
- Lowering the temperature eased back the pace of this diffusion by making the layer phospholipids progress from a liquid to a gel stage.
- Singer and Nicholson supported the consequences of these tests utilizing their liquid mosaic model.
