Answer: Friction
Explanation: Sir Isaac Newton, a soccer ball on the grass will stay where it is unless acted on by a force.
Answer:
Plants perform photosynthesis and cellular respiration.
Explanation:
- Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
- Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
- Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
- Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
The correct answer to this question is <span>The allele for short pea plants is masked during the F1 generation, but it is still present in the genotype.</span>
Answer:
here
Explanation:
In a negative feedback loop, an increase in a factor will result in a change in the body that'll reduce the value of this factor to the set point.
For example, an increase in the blood glucose levels after a meal will cause an increase in the levels of insulin in the blood which will lower the glucose levels.
However, in this example, an increase in the pressure generated by the fetus also increases the frequency of uterus contractions. So the more the pressure, the more the contractions.
Answer:
Without fires, there would be no life on Earth
. Fires are key to maintaining the proper oxygen concentration in the atmosphere; fire regulates the carbon cycle and life, as we know it, is based precisely on carbon
Explanation:
Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.
As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
