kherson [118]2 years ago
7 0

Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

ycow [4]

Answer: The correct answer for the blank is-

Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.

Anestetic [448]

Answer:

b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Explanation:

Hello,

In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Best regards.

Algae are not plants, animals or fungi. They belong to Kingdom Protista, a diverse group of single-celled eukaryotes.
Protists have their own kingdom because many species share some characteristics of plants, animals or fungi.
Algae belong to the group of plant-like protists.
They are autotrophs that fulfill the role of producer in ecosystems because they make their own food via photosynthesis, like plants.
