Answer:

1. Decreased hematocrit.

2. Increase in daily weight.

5. Decreased blood urea nitrogen level.

Explanation:

1. The hematocrit level shows the ratio of red blood cell to total volume of whole blood. When the hematocrit level is decreased it indicates that the concentration of red blood cell in whole blood has decreased hence, proves the child is hydrated.

2. Rehydration (improvement of water retention or restoration)  is directly proportional to daily weight gain, since water has a significant weight (1 litre of water is approximately 1 kilogram. Therefore, increase in the child weight proves that the child is rehydrated.

3. Clinically blood culture doesn't give an information about water content or hydration.

4. Sedimentation rate is used to determine the rate at which red blood cells settles in a test tube; an increased sedimentation rate shows increased inflammatory processes.

5. Blood urea nitrogen level is inversely proportional to blood volume. Therefore decreased blood urea nitrogen level indicates rehydration, this shows the concentration of blood components are low compared to the total blood volume.

The kcat for Rubisco is 3 sec-1 How long does it takeone<br> subunit of Rubisco to do one reaction.
bekas [8.4K]

Answer:

A subunit of Rubisco takes approximately 0.33 s to perform one reaction

Explanation:

The kcat it's a kinetic first order constant that related the properties of the enzyme substrate complexes in a mechanisms and represents the overall first order process of the transformation of the substrate-enzyme complex into product.

Also kcat can be seen as the turnover number of an enzyme, representing the maximum number of substrate molecules that the enzyme can transform into product per time unit and per active site.

If the kcat is 3 s^-1, it means Rubisco can catalyse the transformation of 3 substrate molecules per second.

So, the time that takes a single reaction, should be the inverse of kcat.

To see it more clearly, the time needed for a single reaction is the time observed divided by the number of reactions done during that time.

In other words:

3 reactions ----------- 1 s

1 reaction -------------- x

  • x=1 reaction/3 reactions.s^-1 = 1/kcat = 1/3 s ~ 0.33 s

So the time that takes one Rubisco subunit to do one reaction is approximately 0.33 s

What causes the weather conditions using what we learned.
miv72 [106K]

Answer:

The sun's solar radiation and the wind's movements.

Explanation:

The heat from the sun and air movement is responsible for the weather on Earth. All-weather takes place in the lowest layer of the Earth's atmosphere, which is a gaseous layer that surrounds the planet. The heat of the sun causes the air in this layer to warm to various temperatures in different regions.

ANSWER ASAP PLEASE <br><br> What impact do trees have on the food web?
kati45 [8]

Answer:

Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.
