True. If we all work together to conserve our resources, then the earth will be able to sustain its human population. In this century, many people don't really care about conserving resources because they are too careless to think about how much resources we are wasting on a daily basis. If everyone realizes how much resources we are wasting and helps to conserve them, than earth will have sufficient resources to sustain its human population.
hope this helps:)
please mark thanks and brainliest:)
Answer:
Hope it helps
Explanation:
Earth's amazing gaseous atmosphere is responsible for making life possible on this, the third planet from the Sun. Our atmosphere contains water vapor which helps to moderate our daily temperatures. Our atmosphere contains 21% oxygen, which is necessary for us to breathe, 78% nitrogen,
Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
Question 8-
(a) move out of the cell
(b) cell would shrink
(c) hypertonic
Queston 9-
(a) move into the cell
(b) cell would swell
(c) hypotonic
The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
