Answer:

Many distance runners “carb load” the day before a big race. How does this eating strategy provide an advantage to the runner?

The carbohydrates cause the release of insulin.

The excess carbohydrates are converted to fats, which have a higher calorie density.

The glucose from the carbohydrates lets the muscles make excess ATP overnight.

The excess carbohydrates can be stored in the muscles as glycogen.

Explanation:

<em>During the exercise</em>, the energy is consumed in the form of glycogen that the liver provides, <em>there are evidences that maintain that the consumption of carbohydrates during prolonged sports improves fatigue resistance. </em>

<em> </em>

<em>During exercise</em>, carbohydrates stored as muscle glycogen are used as a specific energy source for muscle. In the liver, however, glycogen is converted by glycogenolysis into glucose, which passes into the blood and from it to the working muscles.

<u><em>The answer is</em></u>: <u>Excess carbohydrates can be stored in the muscles as glycogen.</u>

Which of the following statements about phospholipids is TRUE? A Option A: Each one has two fatty acid chains and the glycerol b

Diano4ka-milaya [45]

Answer:

Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.

Explanation:

Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.

The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>

Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.

This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.

A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic

Dmitry [639]

The type of solution in each beaker based on cell's reaction are :

Isotonic solution : Normal reaction
Hypotonic solution : The cell becomes turgid
Hypertonic solution : The cell becomes deformed

<h3>Matching each solution to the cell reaction </h3>

When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.

Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed

the eyeless gene is required for eye formation in drosophila. it encodes a homeodomain. a. what would you predict about the bioc

Arte-miy333 [17]

<h3>Briefing:</h3>

In Drosophila, the eyeless gene is necessary for the development of eyes. Given that it encodes for a homeodomain, its protein may have a role as a transcription factor that binds DNA in a specific sequence. In situ hybridization can be used to study the gene's mRNA expression pattern, and immunological methods can be used to study the protein.

A. Since the eyeless gene in Drosophila encodes for a homeodomain, one potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.

B. As implied by its function, the eyeless gene should be expressed in the Drosophila cells in charge of eye formation. In situ hybridization of the gene's mRNA expression is one potential test to find the gene. The protein can also be seen via a variety of immunological and staining methods. It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind. Additionally, genetic engineering can determine whether the eyeless gene expressed in other organs can result in the creation of eyes.

C. Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene. Since both of these function as master switches for the genes that create eyes, it is possible to transfer the mouse Small eye gene into Drosophila to observe whether it is expressed. These, however, are simply Drosophila eyes and not comparable to mouse eyes.

<h3>Describe DNA:</h3>

All known organisms, including many viruses, require deoxyribonucleic acid, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce. DNA and ribonucleic acid are examples of nucleic acids.
