Answer:
Option B, Mass
Explanation:
The general relation that gives the relationship between the lumonisity of a star and its mass is
Thus, suppose if the mass of any star is two times the mass of sun then its luminosity will be 100 times the luminosity of sun.
The general relation between luminosity and temperature is
Since luminosity is depended on mass, and temperature is dependent on luminosity , thus it can be said that temperature is also dependent on mass of a star.
Thus, option B is correct.
stars support their weight by making more energy which means more luminosity.

Answer:
Chemical reactions.
Explanation:
Chemistry is the study of different chemicals and their chemical reaction. Every day one uses the things all are made up of chemicals. All the chemicals and matters are the result of the chemical reaction.
For example, water is a compound which is formed by the hydrogen bond between the 2 hydrogens and one oxygen molecule. The properties of water are also different from individual hydrogen and oxygen molecules.
Our body is also made up of 70% to 80 % of water. All the metabolic reaction need water. Similarly, all matters are made up of chemicals. Chemical reactions happen when an organism eat, breathe, division of cell occur, etc. Every physiological process includes a chemical reaction.
The living organisms consist of some biomolecules, carbon, hydrogen, oxygen, nitrogen. All are playing a vital role in different biochemical reactions. Biochemistry is the branch of study in biology which deals with the role of chemistry in biology.
Chemistry and biology are important for studying the different chemical reactions occur in the living organisms. Proteins, carbohydrates, lipids, are all formed due to the chemical reaction and these are known as biomolecules.
b. missense
c. insertion
d. frameshift

Ans. (b). missense.
Sickle cell anemia is an inherited blood disorder, due to defect in oxygen-transporting protein, hemoglobin. It is caused by a mutation in a gene that codes for hemoglobin that substitutes GAG codon (that codes for glutamic acid) with codon GUG (that codes for valine).
It is known as a missense mutation, which leads to formation of a non-functional or defected protein (hemoglobin). The defected hemoglobin gets polymerized and forms fibers that give sickle-shape to the red blood cells.
Thus, the correct answer is option (b).
The type of mutation that causes sickle cell anemia is called missense. That is option B
What is mutation?
Mutation is defined as the alteration that occurs in the gene of an organism which leads to defective formation in the organism.
Sickel cell anemia occurs when there is missense mutation at a single point in their DNA.
Therefore, the type of mutation that causes sickle cell anemia is called missense.

Example:
Glossopteris fossils are the most reoccurring fossils in most land masses. In Alfred Wegener’s Continental drift theory which he claims that the continents of the earth may have relocated themselves from their former positions. Which when you synthesize the whole continents you’ll have the “all-earth” or so-called Pangea. The super continent as Wegener’s continental drift theory suggests. These Glossopteris is event in many places mainly in Africa, South America, Australia, India, and Antarctica. That in the paleontological perspective can assert his theory that these organisms have been roaming and surviving all over this one super continent and were dispersed in, that's why they can be found in many places as mentioned.
