Lamarck's theory of inheritance of acquired characteristics states that the physical changes in the body parts of an organism are inherited to their off spring from generation to generation. During his study of physical appearance ( phenotype) of organism Lamarck said that the characters adopted according to the changes in environment by organism as a physical change in body are inheritable e.g giraffes long neck due to shortage of food the giraffes in order to reach to higher trees had to make their neck long so their neck length was increased and they had long necks so the new offspring when burn had long necks so on this basis he said that the physical changes are inherited. Giraffes with long neck had more chances of survival in the environment.
Answer:
The magnitude of the magnetic field is 0.156 T.
Explanation:
Given that,
Speed of a proton, 
Radius of the circular path, r = 0.2 m
When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :
q is the charge on proton
Here, 
So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.
No more than five trophic levels are present in an ecosystem, most have only 4.
Answer:
BR
Because the first letter comes first
DNA is a group of nucleotides that are linked together. The hydrogen bonds are responsible in making the double helix structure stable. The two strands of DNA are linked and stays in a stable shape because of the hydrogen bonds located between adenosine and thymine base pairs. Three hydrogen bonds are between cytosine and guanine.
