Answer:
1. Option D. 2. Option A.
Explanation:
1. Every individual has some unique characteristics and therefore, their ability to think and interpret things is different from each other. Hence, every individual concludes things on the basis of his/her own experiences, thinking, thoughts, etc.
Therefore, when two scientists get different results while studying the evolution of the universe then it is likely that they will get different results because both of them will have their own style of identification, hypothesizing things, or situations.
Thus, we can conclude that the two groups of scientists got different results because they had different specialties and interpreted their data differently.
2. It is the Chandrasekhar limit which gives an idea about the formation of the white dwarf, neutron star, or black hole at the last stage of a dying star.
The Chandrasekhar limit is equal to 1.4 solar masses.
As per the Chandrasekhar limit, if the mass of the dying star is less than 1.4 solar mass, then it will become a white dwarf.
If the mass of the dying star is greater than 1.4 solar mass, then a neutron star or black hole is formed.
Hence, the correct answer to this question is mass.
I would say A) small reinforcing ligaments.
I say this because ligaments are what connects two bones together through a joint.
HOW DO VIRUSES CAUSE CANCER?
Viruses bring new genes into the cell.
Viral genes act in either of two ways:
1. Viral genes encode proteins that activate the cell
cycle to drive the cell into continuous cell division.
2. Viral genes encode proteins that act as inhibitors
of tumor suppressor proteins. (
End result is loss of control of the proteins that
regulate the cell cycle
Answer: The acrosome of the sperm contains enzymes necessary for the penetration of the egg.
The acrosome is a cap present in the head of the sperm which contains all the enzymes required for penetration into the egg when fertilisation occurs. Capacitation process occurs to remove the glycoproteins found on the surface of the acrosome and this process takes place in the vagina. Without the process of capacitation the fertilisation of the egg by the sperm would not be possible.
Answer: Hemoglobin SC disease is a type of sickle cell disease. People who have Hemoglobin SC disease (also called sickle-hemoglobin C disease) have red blood cells that contain both hemoglobin S and hemoglobin C.
