Answer:
Option A, Start the reaction by absorbing light energy
Explanation:
Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.
Hence, option A is correct.
The answer is Dilutions
Bacterial culture is one of the laboratory examination that could be used to determine if a specimen contain bacteria. But it will hard to count the colony if the bacteria count is too high.
That is why the specimen of the culture need to be diluted to reduce the bacteria count of the specimen, so the result will be easier to count. The unit used would be colony forming unit(CFU) per milliliter.
The correct answer is: A. Species A had more massive jaw muscles than species.
Massive jaw muscles are correlated to more primitive diet. It is believed that shrinking jaw muscles is part of the evolution. It is the way for making the space for a bigger brain.
3. Mechanical energy is the energy used by organisms to function and move.
3. The conservation of energy is the process in which organisms use up the energy in a cycle where nothing is wasted.
Answer:
Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.
The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.
Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.
For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
