Newtons third law is action/reaction, for every action there is an equal opposite force
Answer:
Explanation:
It is given that out of 40, total 5 specimen are selected.
Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by
Number of specimen with certain trait is equal to 3.
Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest 
specimen.
Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
POND
ROCKS
MOUNTAINS
DEAD ANIMALS PLANTS AND WASTES ARE NOW ABIOTIC FACTORS
These are the possible genotypes RR, Rr, Rr, rr
First 3 carries dominant gene for tongue rolling, so they can do it,
while the 4th genotype rr is homologous for recessive, and he/she can't
perform tongue rolling.
