C.
It is C because photosynthesis uses CO2 to form O2 and respiration uses O2 to create CO2, both processes filter oxygen through the atmosphere.

Answer: Option C

Explanation:

Photosynthesis is the process by which plants makes food by the help of the carbon dioxide found in the atmosphere. This process take place in the presence of sunlight.

The end product of this process is glucose with oxygen as a by-product. The oxygen is released into the atmosphere.

The oxygen is used by all the living forms of life on earth and the carbon dioxide is released out by the animals in the atmosphere by the help of the process known as cellular respiration.

A Chinook salmon can jump out of water with a speed of 6.70 m/s6.70 m/s . How far horizontally dd can a Chinook salmon travel th

aksik [14]

Answer:

R = 3.88 m

Explanation:

As the Chinook salmon leaves the water till it gets back into the water it is performing a projectile motion with the following parameters:

V₀ = Launch Speed = 6.7 m/s

θ = Launch Angle = 29°

R= Range of Projectile= Horizontal Distance Covered by Chinook salmon= ?

The value of the range of a projectile is given by the following formula:

R = (V₀² Sin 2θ)/g

R = [(6.7 m/s)² Sin {(2)(29°)}/(9.8 m/s²)]

R = [(6.7 m/s)² Sin (58°)/(9.8 m/s²)]

<u>R = 3.88 m</u>

Suppose you average 75 MPH over the first halfof a drive, and your average speed for the entiredrive is 60 MPH. What was your av

alexandr402 [8]

Answer:

x = 45 MPH

Explanation:

given,

Average speed of the first half = 75 MPH

Average speed of entire ride = 60 MPH

Average speed of the second half = ?

let the average speed of the second half = x MPH

now,

average of entire ride is given as 60 mph so,

$\dfrac{75+x}{2} = 60$

$75+x= 2\times 60$

75 + x = 120

x = 120 -75

x = 45 MPH

hence, the average speed of the second half comes out to be 45 MPH.
