Answer:
d. He did not but instead proposed an erroneous evolutionary mechanism known today as inheritance of acquired characteristics.
Explanation:
Lamarck believed that organism changes as the environment change, and that those changes are passed to offspring ( inheritance of acquired characteristics). He also believed that if a certain structure isn't used by an organism it will gradually disappear through time.
According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
The color of beef is determined by myoglobin because these cells are actually responsible for transporting oxygen-rich molecules to the the tissues of the animal. This characteristic gives it the color that it has and is very abundant in large organisms like cattles.
Plants convert solar energy into chemical energy.
The plants take the sunlight and then convert it into things they can use such as glucose, and also put minerals back into the Earth and soil.

Answer:
The magnetic field due to a solenoid is given as : where, is the permeability of the medium. n is the number of turns or loops in the coil. I is the current flowing in the solenoid.
The magnetic field due to a solenoid can be increased by increasing the number of turns, current and placing an iron core inside the solenoid.
So, the correct option are:
(1) using more wire loops
(2) using a larger current
Hence, the correct options are (a) and (c).
