Answer;

- 1.2 nM

Explanation;

-Smallest Km means highest affinity, can bind substrate better at lower concentrations. The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate. This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity

-Km is therefore, the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.

Which of the following forms would you use to gain insight into the daily nutritional habits of a client
LUCKY_DIMON [66]

In this question the options are missing; here is the complete question:

Which of the following forms would you use to gain insight into the daily nutritional habits of a client?

A. Comprehensive client form

B. PAR-Q

C. 3- day dietary record

D. Food intolerance

The correct answer is 3-dietary records

Explanation:

In health, nutritional habits refer to the consistent preferences of an individual when choosing what to eat, as well as, how much to eat and how frequently. This information is key to help people improve their nutritional habits and health, which might include losing weight, reduce the risk of certain diseases, etc.

Additionally, one of the best ways to understand the nutritional habits of a person is through a 3-day dietary record, which is a type of format in which the individual needs to record all foods and drinks for three days including the quantity of each food and drink and the time. This is the best format for this purpose because it specifically focuses on nutritional habits, while others such as PAR-Q or food intolerances are not directly related to this aspect of health.

In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating
REY [17]

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.

Could two unicorns with no horns have an offspring with a horn
agasfer [191]

Two unicorns with no horns could have an offspring if the horn trait is recessive and the no-horn trait is dominant. There would be a 25% chance of the offspring from these two unicorns having a baby unicorn with a horn.

Imagine a world based on a small nonpolar lipid, instead of based on water. What would be the result in macromolecule structure
Daniel [21]

Answer:

Changes is macro molecule structures are expected among other things

Explanation:

If there were a wold that was based on a small non-polar lipid instead of water there would be massive changes to proteins and carbohydrates. Basic changes would include solubility, catabolism and metabolism and absorption in organisms.  

Many water soluble material would no longer be mobile because there is a lack of media in which to dissolve. However other fat soluble material will be highly mobile and well absorbed. Sessile organism such as trees that depend on nutrients that are dissolved in water for absorption will not longer have this ability.

Finally, abiotic factors such as rainfall and rock weathering will be influenced. The freezing of polar caps and melting of ice will no longer be occurring and there will be an influx of an medium that does not evaporate. Because of this there will be the cessation to the water cycle and probably the end of this life on earth without quick evolutionary and adaptive changes.
