Answer:
1, 2, 3, 4, 5 is the correct answer.
Explanation:
Cerebrospinal fluid is present in the spinal cord and it encompasses the brain.
The main functions of the Cerebrospinal fluid are
- To protect the brain and spinal cord from shock.
- To provide nutrients to a nervous system.
- To remove the waste products from a cerebral metabolism.
- To filter the chemicals from the blood.
- It controls constant pressure between the brain and skull.
- It regulates the pH homeostasis.
- It provides the brain to control its density.
The answer is D.) water.
This is because during photosynthesis, the excess hydrogen atoms get bonded with the oxygen atoms forming water
Hope this helped :)
Answer:
Photosynthesis.
Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels
Answer:
The correct answer is A chemical reaction between oxygen and glucose during cellular respiration.
Explanation:
All living things obtain energy by the reaction of oxygen and glucose during cellular respiration.The cellular respiration involves 3 major pathways glycolysis,krebs cycle and electron transport chain.
These three important metabolic pathways of cellular respiration result in the oxidation of glucose molecules to generate carbon dioxide,water and ATP.
ATP act as the energy currency of the cell which undergo hydrolysis to generate energy that is used to carry out various cellular and biological processes such as muscle contraction,membrane transport etc.
<span>There are 2 parts to the answer:
1. DNA is very long. It is simply not efficient to translate proteins directly from DNA. We need a messenger to copy the information from the DNA in much more compact, manageable and short molecule, thus mRNA copies the code for a specific protein off the DNA, is exported from the nucleus and is then used as a template to create the protein.
2. Regulation. Having mRNA as an intermediate stage between the coding and the translation of the information into protein, enables fantastic and advanced control.
a. It allows the sequestering of DNA into the nucleus. A tremendous advantage for regulation.
b. It allows regulation on the transcriptional level by transcription factors - when and how much we end up with any specific protein.
c. It enables alternative splicing - again another level of control, and adds options for diversity,
These reasons are why RNA is necessary.</span><span>
