Answer:
Explanation:
Without the transformation of ATP to ADP our cells would not be able to produce any energy to function. also, all the mitochondria in the cells would die because this cycle is connected to the electron transport chain in which ions are converted.
The lateral line system provides tactile sense organs ( that is from cyclostome fishes to amphibians or the aquatic vertebrates) with a sense of distant touch, enabling these animals to sense objects that reflect pressure waves and low-frequency vibration. This system made up of multiple of neuromasts.
Schwann - In 1839, he cells are the basic unit of animal structure
Schlieden - In 1838, he discovered cells are the basic unit of plant structure

Answer:
Blood vessels constrict
Explanation:
On seeing danger, impulses are sent to the adrenal medulla. It responds by secreting adrenaline into the bloodstream. This results in the following:
- Increased heartbeat
- Diversion of blood from alimentary canal and skin to skeletal muscles.
- Increased breathing rate and depth
- The liver releases more glucose.
These changes increase energy production especially in the skeletal muscles and prepare animal for sudden fight or flight.
Answer:
The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.
Explanation:
DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.
The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.
What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.
The other options are not correct because:
- <em>The sugar component of DNA is always the same, not different.
</em>
- <em>Organisms always use DNA in the same way.
</em>
- <em>The DNA molecule is always the same.</em>
