Answer:
Yes, this is true. The reason is that the flower transpires and sucks the water in and distributes it as much as it can. You can also flip it upside down and hang it with petals down , allowing the liquid to enter the flower and then retaining color for longer periods of time and having more color.
Explanation:
Photosynthesis is the process where plants create energy. It requires water, carbon dioxide and sunlight. The end result is glucose, which the plants consume, and oxygen. Cellular respiration requires oxygen and glucose. The end result is carbon dioxide, ATP, and water.

Explanation:
Glycine is an amino acid, forms proteins and is also called in its molecular chemical formula as C2H5NO2
A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.
Answer:
166,600J
Explanation:
Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;
K.E = 1/2 × m × v²
Where;
K.E = kinetic energy (joules)
m = mass of body (kg)
v = speed or velocity (m/s)
According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.
K.E = 1/2 × 833 × 20²
K.E = 1/2 × 833 × 400
K.E = 1/2 × 333200
K.E = 166,600
Therefore, the kinetic energy of the roller coaster car is 166,600J.
