What is the role of oxygen in photosynthesis and in cellular respiration.

1 answer:

5 0

The role of oxygen in photosynthesis and in cellular respiration is: Oxygen is a product of photosynthesis and a reactant in cellular respiration.

<h3>What is Photosynthesis?</h3>

Photosynthesis is the process whereby green plants manufacture their food using energy from the sunlight, carbon dioxide and water to synthesize food in form of glucose and produce oxygen as a by-product.

<h3>What is Cellular Respiration?</h3>

Cellular respiration is a metabolic process in living organisms whereby glucose is broken down with the aid of oxygen, to release chemical energy.

Thus, the role of oxygen in photosynthesis and in cellular respiration is: Oxygen is a product of photosynthesis and a reactant in cellular respiration.

A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s int

mamaluj [8]

Answer:

The final speed of bicycle would be 27 m/s².

Step-by-step explanation:

Given :

$\small\red\bull$ Initial velocity (u) = 15 m/s
$\small\red\bull$ Acceleration (a) = 3.0 m/s²
$\small\red\bull$ Time = 4 seconds

To Find :

$\small\red\bull$ Final velocity (v)

Using Formula :

$\longrightarrow{\pmb{\sf{v = u + at}}}$

$\small\blue\star$ v = final velocity
$\small\blue\star$ u = initial velocity
$\small\blue\star$ a = acceleration
$\small\blue\star$ t = time taken

Solution :

Substituting the values in the formula to find the final velocity :

$\longrightarrow{\sf{v = u + at}}$

$\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}$

$\longrightarrow{\sf{v = 15 + (3 \times 4)}}$

$\longrightarrow{\sf{v = 15 +(12)}}$

$\longrightarrow{\sf{v = 15 +12}}$

$\longrightarrow{\sf{v = 27 \: {m/s}^{2}}}$

$\star{\underline{\boxed{\red{\sf{v = 27 \: {m/s}^{2}}}}}}$

Hence, the final speed of bicycle would be 27 m/s².

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expense

djverab [1.8K]

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

At what time do guests start arriving for the 9 a. M. opening?

Umnica [9.8K]

The time guests should arrive for the 9 am opening is 8:30am.

<h3>What time should guests start arriving?</h3>

When guests are expected at an event, best practice is to arrive 15 minutes before the opening time. If 30 minutes is subtracted from 9am it is 8:30 am.

If guests aim to arrive at exactly at 9am, it is likely that they would not be at the opening on time.

Here are the options to this question: A. 1 a.m. B. 9 a.m. C. 6 a.m. D. 8:30 a.m.
