Answer:
Option A
Explanation:
As we all know, energy can never be created . Also it can never be destroyed. However, it can only be changed from one form to the other. In this case, when a pool ball is striked by a stick, the kinetic energy of stick is transferred to the ball along with release of sound. Sound is just another form of energy.
Now, when this ball strikes other balls, the same process is repeated i.e the ball strikes another ball and passes on its kinetic energy along with release of sound energy. Every time sound is released, the amount of kinetic energy transferring from one body to other reduces.
Option A is correct
Answer:
The main use of a beak is for feeding. Since beaks are mainly used for feeding, the variation in beak shape and size mostly has to do with the food that each species prefers. Some beaks are made for digging seeds out of shells while others are designed to dig deep into the ground to pull out prey items.
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
Answer:
symbiosis.
Explanation:
The term that you are referring to is symbiosis. (a symbiotic relationship)
Symbiosis is a proximate and often long-term interaction between two or more different biological species.
