Answer: The correct answer is-
C) Genes.
Traits are the particular characteristics of an individual ( such as eye color, skin color, hair color) that are depicted by genes ( segment of DNA that corresponds to particular protein, which determines specific trait of an individual).
Genes carry genetic information ( in the form of DNA sequence) that is passed from one generation to the next.
Gregor Mendel studied different genes ( corresponding to traits of pea plant) and their pattern of inheritance.
Thus, scientist used his data to conclude that traits are passed from parents to offspring through genes.
Answer:
The correct answer is D. is a system that differentiates self from nonself to neutralize harmful invaders.
Explanation:
A defense system that protects the host body from pathogen infection is called the immune system. This immune system is made up of many different barriers which helps in preventing illness from pathogen attack.
Physical and chemical barriers provide the first line of defense to the body for example skin, mucous membrane, lysozyme in saliva provide first line of defence. Second line of defense is provided by non-specific immune cells like mast cells, macrophages, dendritic cells, etc.
The third line of defense is provided by pathogen-specific immune cells like T lymphocytes and B lymphocytes. These cells have the ability to differentiate self and non-self cell and kills the non-self cell that come from outside the body.
It is Important for scientist to use data because data is what they use to write their observations. Scientist organize data in to the data tables.
Answer:
Quasar is the answer
Explanation:
Quasar have been shown to travel from 300% of the speed of light, to 8 times the speed of light according to red shift data.
