Answer:
it shows that co2 is absorbed by the atmosphere.
when the animals respire they produce co2 which is release in atmosphere and in presence of sunlight and chlorophyll the plants manufacturs the food and releases the oxygen in the atmosphere .

Answer: The mass would be 1000m3 and the volume would be 1000kg
Explanation:
Answer:
A: Copper is a good conductor
Explanation:
For an electrical current to flow through something, the main power source has to fight against the resistivity. Copper wire has a very low level of resistivity making it an excellent conductor. Basically, copper is super bendy and flexible, electricity.
Fun fact, sinc humans are also super bendy and essentially big sacs of all things wet and watery, we're considered to also be excellent conductors. We also have very intricate circuitry and a lot of natural electricity so basically, we were made for it, especially since the body already used little bits of electricity to function.
Natural selection, it's simply when one animal outsmarts the rest and lives on to reproduce and carry on it's traits, when the animals who have not adapted well do not have the chance to reproduce, and the population dies off.

Answer:</h2>
|B| = 47.0 units
<h2>
Explanation:</h2>
The sum of two vectors (A) and (B) gives another vector (A + B). i.e
(A + B) = (A) + (B) ----------------(i)
<em>From the question;</em>
Vector A = 28.0 units in the positive y-direction. This means that the value of the x-component is zero and the value of the y-component is +28
In unit vector notation vector A is given as;
A = 0i + 28.0j
Vector A + B = 19.0 units in the negative y-direction. This means that the value of the x-component is zero and the value of the y-component is -19.0
In unit vector notation, vector A + B is given as;
A + B = 0i - 19.0j
To get the magnitude of vector B, make B the subject of the formula in equation (i) as follows;
(B) = (A + B) - (A) ------------------ (ii)
Substitute the values of the vectors (A) and (A + B) into equation (ii) as follows;
(B) = (0i - 19.0j) - (0i + 28.0j)
(B) = - 19.0j - 28.0j
(B) = - 47.0j
The magnitude of B, |B|, is therefore;
|B| = |-47.0|
|B| = 47.0 units
