Answer: urine concentration is the best answer to this question
Explanation:
Urinary hydration biomarkers provide the best index of day-to-day hydration is urine concentration.
The answer is option B.urine concentration
What is the best index for day-to-day hydration?Plasma osmolality, urine osmolality, and urine particular gravity are the maximum widely used markers of hydration. however, urine shade has also been used with reasonable accuracy while laboratory analysis isn't to be had or while a short estimate of hydration is vital.one of the easiest methods to check your hydration is thru toilet frequency and urine color. urine should be light yellow and also you have to be emptying our bladder on common 5-8 instances according to day. some other way to decide hydration stages (especially after a run) is a sweat take a look.Learn more about urinary hydration here:-https://brainly.com/question/1301665

What does this graph tell you about the concentration of salt inside the cell?
The concentration of salt inside the cell was lower than the concentration of salt in the salt water, since the cell got much smaller in size due to water outward movement.
What is osmosis?Osmosis is the movement of water molecules through a semi-permeable membrane from regions of low solute concentration to regions of high solute concentration.
If salt concentration is higher inside the cell than outside, water will move into the cells. However, if the salt concentration outside the cell is higher, water will move out of the cells.
The cell became smaller, indicating that water moved out of the cell.
Thus, the salt concentration in the cell was lower inside the cell.
In conclusion, water moved out of the cell by osmosis.

Energy is stored in biological molecules like carbohydrates, lipids and nucleic acids (ATP).
Describe how different forms of energy are converted at least three different ways in an autotroph.
ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be "recharged" to form ATP by adding energy, combining with Pi in a process that releases a water molecule.
Where the energy of ATP?As energy is released, they form ATPs, binding phosphate to ADP. So the energy is in ATP. The process of binding phosphate to ADP is called oxidative phosphorylation.
There are three common energy-producing processes for making ATP:
The ATP-CP system, or phosphagen;Anaerobic glycolysis, or lactic acid system;The oxygen system.See more about ATP at brainly.com/question/14637256

3) _______________________________________________________________
4) _______________________________________________________________
3. How might the changes that you identified affect the protein’s structure?
Example: The change would likely have no effect. Neither valine and isoleucine would promote hydrogen bonding with water, because their R groups are nonpolar and thus hydrophobic.

4. Assuming that the mutations are adaptive, how should the changes that you identified affect the stability of the protein at low and high temperatures?
The amino acids that changed between the three species are;
The changes in the chemical properties of the R-groups are given as:
Both valine and isoleucine are nonpolar.Both glycine and alanine are nonpolar.Glutamine is an uncharged polar group and Lysine is a charged polar group.Both glutamic acid and aspartic acid are charged polar group.How might the changes that you identified affect the protein’s structure?In scenario 1 and 2, the modifications would have zero effect.
In scenario 3, the polar groups are detected on the surface of the protein, thus, it is correct to state that both glutamine and lysine are polar and the modifications will have zero effect.
With regards to scenario 4, the change will have no impact, given that both glutamic acid and aspartic acids are R groups that are negatively charged.
Assuming that the mutations are adaptive, how should the changes that you identified affect the stability of the protein at low and high temperatures?These mutations are critical for protein's three-dimensional structure stability.
For example, due to the proteins from thermophilic creatures, they are able to live at high temperatures and survive at low temperatures.
This is because they frequently have a large network of salt bridges on their protein surface, which offers thermo-stability to these proteins and prevents denaturation owing to the high temperatures in the environment.

If the DNA sequence is CCAATTGA, what is the compliment?
GGTTAACT is the complement of DNA sequence CCAATTGA.
What is a complement sequence of DNA?A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.
Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).
Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.

Hi, According to what I understand, the term is heterotroph, not hetrotrop [Tropism is concerned with how organisms react to a certain stimulus]
The word "heterotrophy" refers to organisms that do not synthesis their food or carbohydrates in the presence of photosynthetic pigment using CO2, water, or solar energy. With the exception of Euglena, they cannot synthesis their food or carbohydrates (it is unicellular and contains photosynthetic pigment). Carnivores, herbivores, etc. are heterotrophs.

Cell division is the process by which a parent cell divides into daughter cells.
Why is cell division important?Cell division is important as it helps in the production of identical copies of cell. It also helps in repairing the damaged tissues or cells that are worn out.
The difference between mitosis and meiosis is that mitosis results in two identical daughter cells while meiosis results in four se-x cells.
Mitosis creates diploid daughter cells while meiosis creates haploid daughter cells.
