Answer:
The correct solution is "37.5 km".
Explanation:
Given:
Distance between the trains,
d = 75 km
Speed of each train,
= 15 km/h
The relative speed will be:
= 
= 
The speed of the bird,
V = 15 km/h
Now,
The time taken to meet will be:
hence,
The distance travelled by the bird in 2.5 h will be:
⇒ 
Answer:
The Temperature is the measure of Average Kinetic Energy of the molecule in the substance.
Temperature and Kinetic Energy of molecules are related by the equation
Where
<E> denotes average kinetic energy
k - Boltzmann constant
T - Temperature of the substance
Explanation:
The energy inside the substance is characterised by translational and vibrational motion.
The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
As the molecules of a substance vibrate faster their temperature increases.
Thus an increase energy corresponds to an increase in temperature
<E> α T (α denotes proportionality)
Answer: translate DNA into RNA <3
Explanation:
An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.
A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.

Answer: B) As something approaches an octopus, it shoots a cloud of ink.
A stimulus is something which brings physiological change in the internal or external environment of the organism. Sensitivity is the ability of an organism to respond to the external stimulus or stimuli. These changes are detected by the sensory receptors present in the different parts of the organism. A stimulus can be light, chemical, pressure, temperature and other living organism.
As something approaches an octopus, it shoots a cloud of ink is a physiological response of the octopus to an immediate threat. This immediate threat could be another marine predatory organism acting as a stimulus.
