Answer:
The answer is C. DNA from the S bacteria is necessary for bacterial transformation to occur.
Explanation:
When heat-killed nonvirulent S bacteria will be treated with enzymes that degraded DNA it will destroy the genetic information required for cell survival. DNA is very essential for an organism and is called the molecule of life. DNA degradation is also a part of cell death called apoptosis. That's why all the samples grew except the one where DNA was enzymatically degraded.
Answer:
The correct answer will be option- A
Explanation:
Red drop effect is the effect observed by the light present in the spectrum of the wavelength of red light. The effect is observed with the decrease in the quantum yield of the oxygen formed per quantum of light when the wavelength of light exceeds 680 nm.
The decrease of quantum yield is observed due to the fact that the oxygen is formed by the breakdown of the water molecule during light-dependent reaction which is initiated by the PS II which begins the chain at 680nm.
If light exceeds the 680 nm then, PS II will remain inactive and thus will abrupt the dissociation of the water molecule and thus the formation of oxygen during the light-dependent phase.
Thus, option-A is the correct answer.
Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.
Both bacteria and
amoeba are single-celled organisms. They both have ribosomes.
Bacteria is a
prokaryote. It lacks membrane-bound nucleus, mitochondria, chloroplasts or any
membrane-bound organelles.
Amoeba is a eukaryote.
It has a "true" nucleus containing its DNA and organelles which is
responsible for energy production and protein transport.<span>

Answer:
There are several small products of photosynthesis but the main product is glucose
. Another main product is oxygen as well.
To allow resources to be replenished naturally is the most important reason to reduce demand for renewable resources.
- The term "renewable resources" refers to natural resources that are replenished by nature.
- These are resources that can be used indefinitely and are replenished naturally, such as sunlight, water, and air, among others.
- Natural resource exploitation and consumption harm the ecosystem and cause pollution.
- Utilizing less natural resources, such as wood and fossil fuels, will safeguard both environmental and human health.
- A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, also known as a flow resource.
- This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
