<span>Trophic level is level in the movement of energy through an ecosystem. It describes the organism's feeding status in an ecosystem.
</span>An organism that feeds at several trophic levels is an example of a carnivore (<span>animal that gets food from killing and eating other animals.).</span>
Cortical nephrons can be distinguished from juxtamedullary nephrons by: their filtration rate.
I hope this helped:)
Answer:
Option a. is correct
Explanation:
A mutation refers to a change in our DNA sequence which causes it to break down. It occurs due to the following reasons:
1. Due to mistakes when the DNA is copied
2. Due to environmental factors such as UV light, smoking.
3. Exposure to specific chemicals or radiation
The mechanism for reactive oxygen species to cause mutation is that bases are oxidized to a variety of different products which might pair with a different base than the original base would have.
1) Both involve electron transport chains.
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
The correct answer among the choices listed above is the first option. The number of growth rings is an indicator of the age of a woody plant. A growth ring a concentric layer of wood which is developed on a regular period of growth of a plant.
