D. Lack of sunlight
Explanation:
In a forest, an example of a limiting factor is that lack of sunlight.
Limiting factors in an ecosystems are the that factors usually made up of environment resources that affects the growth and abundance of organisms in an ecosystem.
- Examples are sunlight, water, nutrient, air etc
- In a forest, sunlight is one of the limiting factors.
- Forest vegetation are stratified.
- The broad leaved canopy trees dominates and receives the bulk of the sunlight.
- The undergrowth beneath competes for the little sunlight that reaches below for their own use.
- Distributions of sunlight in an ecosystem affects the way in which vegetation are dispersed.

We know that animal populations exposed to higher concentrations of radioactive activity, often suffer deleterious genetic mutations. Thus, the answer would be <u>B.) a higher than average mutation rate.</u>
Answer:
Can of soup and pop Tarts.
Explanation:
Can of soup will provide 1 mole of sodium whereas pop Tart provides potassium in the least mass because the concentration of sodium and potassium in can of soup is higher than other food items. The can of soup has 300 mg of sodium and pop Tart has 0.5 g of potassium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 0.14 g, 0.12 g, 0.3 g, and 0.35 g of potassium respectively and can of soup, honey nut, frosted flakes and Oreos has 190 mg, 150 mg, 80 mg, and 180 mg of potassium respectively which is lower than pop Tart so we can say that less amount of pop tart provides more potassium. 9579 of soup and 7505 of pop Tart are the masses required for I mole sodium and potassium.
The right answer is Mitochondria.
In the 20th century, scientists thought that plastids and mitochondria could come from procaryotes (bacteria). These would have been ingested by cells and live within them (in symbiosis). This endosymbiotic theory became perfectly plausible when it was discovered (in the 1950s and 1960s) that these organelles contained theori own DNA, tRNA and rRNA.
Answer:objects that contain dust and gas
