What reaction fuels the burning of the sun?

Biology

kobusy [5.1K]3 years ago

The source of the sun's fuel is hydrogen and helium gases. Through a special chemical reaction, called nuclear fusion, the hydrogen gas is "burned" releasing an enormous amount of energy in the form of light and heat.

Answer:

Nuclear fusion reaction

Explanation:

The nuclear fusion process refers to the condition when two nuclei of smaller atoms are combined with one another to form a heavy nucleus, resulting in a large amount of energy.

This process takes place extensively in the core of the sun that helps the sun in burning, releasing a significant amount of heat energy.

This fusion reaction emits photons of higher energy, which are commonly known as the gamma rays, and it subsequently travels through the radiative layer of the sun that surrounds its core.

The reaction of nuclear fusion thereby results in the conversion of hydrogen into helium as well as helps in the conversion of mass into energy.

Lesch-Nyhan syndrome is an X-linked, recessive condition caused by mutation of the HPRT1 gene responsible for purine metabolism.
Elanso [62]

Answer:

B. The father did not contribute a sex chromosome to his daughter due to nondisjunction of the sex chromosomes. The daughter is XO and her only X chromosome came from her mother, who was a carrier.

A.The mother's X chromosomes failed to separate during meiosis, and the daughter inherited two X chromosomes with the Lesch-Nyhan mutation. The father contributed no sex chromosomes.

Explanation:

As seen in the question above, a little girl was diagnosed with Lesch-Nyhan syndrome, which is an X-linked recessive condition caused by a mutation in the HPRT1 gene responsible for purine metabolism.

The little girl's parents do not have the syndrome, and no one in the little girl's paternal family presented this syndrome, however, we know that the maternal grandfather of the little girl's mother had the syndrome, which means that it was the mother's genetic material that contributed to the development of the syndrome in the little girl. This was because the little girl did not receive any X chromosomes from her father, but she inherited the two X chromosomes from her mother that coded for the Lesch-Nyhan mutation. This happened because the mother's X chromosome disjuction did not occur during meiosis I.

As shown above, the father did not contribute any sex chromosomes to his daughter, which means that the daughter is XO and her only X chromosome came from her mother, who was a carrier.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is
Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp
