How is it possible for white dwarfs to have a lower luminosity than the sun even though it is much cooler?

Biology
1 answer:
ratelena [41]3 years ago
4 0

Answer:

White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.

Explanation:

As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.

Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white.
Alinara [238K]

Three out of four of their offspring will be white when Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white. Thus, the correct option is B.

<h3>What is law of dominance?</h3>

A trait is represented by two contrasting factors of a gene in a heterozygous individual, while the homozygous individual has two copies of the identical factors, according to the law of dominance. As a result, the heterozygous rabbit's genotype will be Bb, whereas the homozygous recessive rabbit's genotype will be bb.

FF X ff

     ║

 Ff (F1 generation)

    ║

Ff X ff (self pollination- F2 generation)

     ║

Ff, Ff, Ff, ff

3: 1 (black: white)

What are organic molecules that catalyze reactions in living system
aksik [14]

Answer:

enzymes

Explanation:

Enzymes are organic molecules made up of proteins that catalyze reactions by either speed up or controlling the chemical reaction.

Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reactions. For enzymes to catalyze a reaction, the substrate must fit in the active site on the surface of the enzyme. This forms an enzyme-substrate complex. The enzyme speeds up the formation of the products.
