Answer:
used to complete the glicolisis process
Explanation:
A glucose molecule will generate the necessary energy to the body to compete their own metabolic processes.
At the begging of the process, the glucose change into 2 molecules of gliceraldehyde 3 - phosphate. In this first process the glucose molecule consume 2 molecules of ATP (the energetic molecule).
After this first process, the aldehyde turns into piruvate, during this process, there is produced 2 molecules of ATP, so it is producing chemical energy.
If during this process the cell need to enter into another metabolic process (pentose ways) then the gain of ATP deplets.
An element is a pure substance which means it cannot be broken down by any means.
Answer:
In order to determine the rate at which the sediment layers were deposited
Explanation:
Iridium is an important element that belongs to the Platinum group and they are dominantly present in the asteroids and comets. They are the key evidence that suggests the occurrence of an asteroidal impact or a mass extinction event that has taken place in the geological past.
The presence of Iridium mixed with the clay sediments in the boundary between the Cretaceous and Tertiary (K-T boundary) suggested the mass extinction event that wiped out numerous life forms from the earth.
The famous scientist Dr. Luis Walter Alvarez suggested measuring the concentration of Iridium in this K-T boundary in order to determine the rate at which these sediment layers were deposited. They were able to determine that these Iridium elements were present due to the asteroid impact on earth, that wiped out the dinosaurs from the earth. They also considered that this element can be produced from the eruptions of volcanoes.
Answer: What do you need help with?
Explanation:
A biome is a collection of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate.
