Describe how the process of photosynthesis led to an increase in cellular respiration and more complex cells
koban [17]

Answer:

<u><em>BRIEF EXPLANATION</em></u>

Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.

Explanation:

<em><u>MAIN ANSWER TO THE QUESTION.</u></em>

Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.

Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.

12345 [234]

Answer:

d. xylem and phloem

Explanation: plants possess vascular bundles.these are bundles which includes xylem and phloem tissues and transport useful substances to various plant cells.

New Xylem and phloem are formed from the vascular cambium which divides into new cells .

Xylem and phloem are thin and slender with pipe-like structure.

The xylem transports water and dissolved nutrients to the cells where they are needed.

The phloem transports the product of photosynthesis (sugar) to parts what they are used up or stored .

Xylem cells are dead and consists in vessels,trachieds and xylem parenchyma.

Phloem cells are dead and consists in sieves cell, companion cells, phloem parenchyma and phloem fibres.

A 12 pound shot put and a small metal BB are dropped from a tall tower, inside a vacuum chamber,
hichkok12 [17]

Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.

<h3>What affects the speeds at which these objects fall?</h3>
  • The falling speeds in both air and a vacuum will be the same for both objects.
  • This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
  • The same will occur in water if and only if the densities of the two objects are equal.

Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.
