white dwarf

Explanation:

A appears on the chart at the point of low luminosity but high surface temperatures. This indicated  a White Dwarf

A red giant is highly luminous stars mainly because of its large size. However, its surface temperature is hot a high when compared to white dwarfs. White dwarf surface temperatures can reach billions of degrees kelvin while red giants reach up to 5000 K on their surface.

A white dwarf is the last sequence of a low-mass star cycle and follows the red giant phase.

When is selective breeding okay and when is it not? Provide evidence.
jonny [76]

Answer:

Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.

improved so that mankind can benefit from it.

Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely.  When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.

Onsidering that gluconeogenesis requires a net input of 4 atp equivalents compared to glycolysis, why would a cell utilize this
Pani-rosa [81]

The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.

  • The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
  • Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
  • For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.

Therefore, gluconeogenesis conserve more energy.
