Why does evolution have to with change over time?

1 answer:

6 0

Evolution is the change in an animal over time. Evolution causes this one animal to branch out into many different species of animals.
How evolution starts- There is a mutation in the genes of one animal. If the mutation helps the animal, than the animal breeds and passes on this mutation. This is natural selection. Natural selection is the starting point of evolution because all of the helpful mutations get passed down to change the species over time for the animals' benefit.

Which label identifies the part of the ATP molecule that changes when energy is released in the cells of all living things, and

kondaur [170]

• When the bond present between the two phosphate groups breaks down, it releases energy.

• In a living cell, energy is released to perform many essential metabolic activities; the process is called respiration.

Further Explanation:

Respiration is a chemical process that breaks down glucose molecules and then produces ATP. The cellular respiration includes three different steps to generate energy in a living cell, namely glycolysis, Krebs cycle, and ETC (electron transport chain) these are the three different cycle that helps in ATP generation. During glycolysis, there is a net release of ATP (produce energy in a living cell) and NADH molecules.ATP has three phosphate groups in their structure, to release energy the bond between these groups’ breaks to release one inorganic phosphate.

The molecule of ATP is synthesized due to the presence of a proton gradient in the inner membrane of mitochondria. Synthesis of ATP is possible in the membrane only if the proton gradient is well established any leakage in the membrane will interrupt the gradient and directly affect the ATP synthesis.

A cork is dropped into a pool of water creating waves. Does the wavelength depend upon the height above the water from which the

shutvik [7]

<u> The cork initially has some potential energy when it is held above the water (the greater the height, the higher the potential energy). When it is dropped, such potential energy is converted to kinetic energy as the cork falls. When the cork hits the water, that energy travels through the water in waves. </u>

Explanation:

In this lab, you will take measurements to determine how the amplitude and the period of waves are affected by the transfer of energy from a cork dropped into the water.

The cork initially has some potential energy when it is held above the water (the greater the height, the higher the potential energy).

When it is dropped, such potential energy is converted to kinetic energy as the cork falls. When the cork hits the water, that energy travels through the water in waves.

Materials :

large bowl or basin
water
cork (or ping pong ball)
stopwatch
measuring tape
Fill a large bowl or basin with water and wait for the water to settle so there are no ripples.
Gently drop a cork into the middle of the bowl.
Estimate the wavelength and the period of oscillation of the water wave that propagates away from the cork. You can estimate the period by counting the number of ripples from the center to the edge of the bowl while your partner times it. This information, combined with the bowl measurement, will give you the wavelength when the correct formula is used.
Remove the cork from the bowl and wait for the water to settle again.
Gently drop the cork at a height that is different from the first drop.
Repeat Steps 3 to 5 to collect a second and third set of data, dropping the cork from different heights and recording the resulting wavelengths and periods.
Interpret your results.
