Answer:
We can see that the energy and mass are transformed in other forms via cellular respiration and photosynthesis. Plants breathe carbon dioxide and expel oxygen.
Explanation:
Photosynthesis is where a plant takes light from the sun, water from the soil, and carbon dioxide from the air, and turns it into two things: glucose, which it uses for energy, and oxygen, which it releases into the air. ... Matter and energy is neither created nor destroyed, so it all has to go somewhere

A football field is 0.001 km in length. Since the 1 is in the thousands place, you’d have to run back and forth (0.001 km) 1000 times.
0.001 x 1000 = 1
The 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.
<h3>What is a mole ?</h3>
A mole is a universal unit used to measure large number of atoms , molecules of an element.
one mole is equal to the Avogadro's Constant.
Mole is equal to the ratio of the mass of a compound to its molecular weight
It is given that Vitamin D is present
no. of molecule = 6.023 * 10²³
6.023 * 10²³ molecule constitutes of 1 mol
1 mole is equal to the molar mass of a compound/ element
Therefore 1 mole = 384.7grams of Vitamin D
and hence 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.

Answer:
The amount of mass and matter in all the transformations of the clay ball will remain the same or constant
Explanation:
From the law of conservation of mass we have, for an enclosed system to and from which there is no transfer of matter or energy, mass cannot be created nor destroyed, and remains constant at the given value, but the matter which make up the mass can be changed into different forms
Therefore, the clay ball can be transformed into different shapes and will still posses the same initial mass before the transformation, provided there are no transfer of matter or energy from the clay ball system.
Answer:
you are correct
Explanation:
i double checked u are correct :D
