EastWind [94]3 years ago

The process that Darwin described as "descent with modification" is the process of evolution.

"Descent with modification" is one of the fundamental ideas behind Darwin's theory of evolution. According to Darwin, the characteristics of an organism are inherited. Offspring with inherited characteristics which allows them to compete best with the limited resources in the environment will survive. Organisms will pass the traits providing an advantage to survive and reproduce to the next generations. Over time and generations, the traits providing reproductive advantage will become common among the polpulation. This will lead to change in populations over generations in a process called the "descent with modification".

It may be concluded that he needs 11 grams more protein to meet the recommended allowance.

<h3>What are proteins?</h3>

An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds. All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.

The DRI (Dietary Reference Intake) is 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound per persom

This may be sufficient to avoid deficiency, but how much you actually require will depend on a variety of factors, including your exercise level, age, muscle mass, physical goals, and general health.

2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr
atroni [7]

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

             NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

         Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

              That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.

A characteristic that can be observed or measured without changing the composition of the substance is called?
melamori03 [73]
Physical property is the characteristic that can be observed, using the five sense, without changing or trying to change the composition of the substance. Chemical property on the other hand is a characteristic of how the substance reacts. It can not be observed without changing the substance into something else. A physical change is a change in which the form or appearance of matter changes, but not its composition.

Why is it necessary to have a constant input of energy into an ecosystem?
IrinaK [193]
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
