Marianna [84]3 years ago
7 0

Answer: It is a helium nuclei.

Explanation: Alpha particles are produced when a larger nuclei decays into smaller nuclei in radioactive decay. Alpha particles have mass number and atomic number as 4 and 2 respectively.

General representation of alpha decay :

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}Y+_2^4\textrm{He}

Alpha particles are identical to helium nucleus. So alpha particles and helium nucleus are infact the same.
its Atomic Mass = 4
its Atomic number = 2
So it has two electrons , two neutrons.
It generally occurs in the decaying of a substance.

Through which of the following processes is carbon directly transferred between living organisms and the environment?
sertanlavr [38]

Answer:

The answer is carbon cycle.

Explanation:

The carbon cycle is an important process for living organisms. As plants prepare their food through photosynthesis and is also an important source of fossil fuels for human activities.

Therefore carbon atoms are regenerated again and again in the carbon cycle process. This recycling process takes place between livings and nonliving things in the environment and also within the earth biosphere.

Abundance supply of carbon is necessary to carry out the biological processes. The entire carbon cycle is actually made up of sourced and sinks elements.

Mitosis occurs during which phase?
lara [203]

Answer:

Prophase

Explanation:

Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
