As a star goes through this cycle their _____ changes.
A - luminosity
B - brightness
C - all of these
D - temperature
Answers
Answer:
option C. all of these.
Explanation:
The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.
What is a complete cycle of a particular star?The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.
The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.
The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.
The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.
Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.

The word comes from the Greek word oikos which means "house."
A Population is group of organisms of the SAME species living in the same area at the same time and sharing a common gene pool. This group is potentially able to interbreed with one another.
In ecology, the term Community refers to the populations of animals and plants that live within a specific region under similar environmental conditions. These populations of plants and animals live and interact with one another and their environment. Between Humans, the term Community generally refers to a group of people living in the same locality or sharing some common characteristics (i.e. ethnic, cultural or religious).

What is ABO blood grouping ?The blood grouping can be defined by the presence of surface antigens in the red blood cell which are A and B. The gene present on the parent chromosome can determine the blood group.
Blood type A represents to the presence of gene A, and its genotypic expression can be A/A or A/O.
Type B blood group where genotype is represented as B/B or B/O, is due to the presence of a gene containing the B antigen.
AB blood group which is codominant- has one gene for A and another for B, with genotype A/B.
Blood type O is mainly characterized by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.
