What are the products of step 1 of the hydrogen fusion process in the Sun? Check all that apply.

Ne4ueva [31]

Explanation:

Nuclear fusion is a process in which two small nuclei combine together to result in the formation of a larger nuclei.

In Sun, the first step of hydrogen fusion includes combining of two hydrogen nuclei to result in the formation of a deuterium, positron and neutrino.

The nuclear fusion reaction inside the sun is as follows.

$^{1}H + ^{1}H \rightarrow ^{2}D + positron + neutrino$

Thus, we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen, a neutrino, and a positron.

<h2>The correct answer is: B.</h2>

Explanation:

A variety of species become threatened or endangered due to various natural and anthropogenic factors.
Natural factors like climate change, global warming, flood, volcanoes, forest fires, avalanche, earthquake, tsunami etc cause the death of many species of organisms and often cause the extinction of several endemic and rare species.
Man-made factors like habitat destruction, mining, quarrying, deforestation, poaching, etc also has similar impact on species diversity.
Conservation of animals can be defined as the procedure adopted to promote the well being of different species of animals such that they can survive and reproduce to maintain their existence on earth without getting threatened, endangered or extinct.
A Threatened species can be defined as the one which has a high probability of becoming endangered in the near future.
An Endangered species can be defined as the one whose population has reduced to such an extent that the probability of the species to become extinct in the near future becomes exceptionally high.
An Extinct Species can be defined as the one whose last surviving individual has died. The ability of such a species to breed and recover its population gets lost much earlier.
Conservation program carried out for the preservation of a particular animal species includes the protection of their surviving habitat, breeding habitat and also their hibernating habitat.
A particular habitat can be occupied by multiple species of organisms which occupy different ecological niches.
Therefore, conservation of the habitat of a particular species of organism will simultaneously cause the conservation of other species present in the same habitat.
Hence, this would indirectly cause the conservation of other endangered species.

Mary determined that 5 pollen grains could fit along the diameter of the field of view of her microscope. If each pollen grain h

KengaRu [80]

Answer:

1.5mm

Explanation:

According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.

This means that the diameter of the field of view of Mary's microscope can be calculated as follows:

Diameter of each pollen × no. of pollen that fit in

= 0.3mm × 5

= 1.5mm

Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

Distinguish between a waxing moon and<br> a waning moon.

Dmitrij [34]

Answer:

Waning is the opposite, or decreasing after a full moon, and is always illuminated on the left. Then, there is a waxing or waning Gibbous moon, which means more than half of the moon is illuminated. Waxing means to increase/get bigger, and waning means to decrease/get smaller.
