Answer:
Most of the scientists worldwide do not accept this theory.
Explanation:
Lamarck's theory states that acquired traits can be passed on from parents to offspring. This theory can not be sufficiently substantiated by indisputable scientific evidences hence it is not accepted by majority of scientists worldwide.
Since science is empirical and the theory is mostly based on vague speculations rather than concrete evidence, it was long rejected by many biologists.
This theory suggests that all life forms will gradually evolve from simple to complex organisms while the simple organisms gradually disappear. This is not the case.
Answer:
Part A
Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population
Part B
The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T
Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.
Part C
At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1

Answer: An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

Answer:
Sound waves required a medium.
Explanation:
In space, there is only vacuum hence no any medium for sound wave travel.
Since sound waves are mechanical waves, they require a material medium such as air, hence no sound transmission.
