Answer:
Glycolysis occurs in the Cytoplasm
Electron Transport Chain occurs in the Mitchondria
Krebs Cycle also occurs in the mitchondria
Explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH hydrogen ions and electrons into the transport chain.
The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria.

Since the average osmotic pressure of the brain is 300mM and the concentration of the solution is 280mM, that means there is 20mM difference between the brain cells and CSF. This will induce osmosis and cause water to move from the CSF into the brain until the concentration becomes same. Assuming brain volume is 1200ml and the CSF constantly replaced., then the estimation of fluid should be: 20mM/300mM * 1200ml= 80 ml
If it made percent it should be: 80ml / 1200ml= 6.67%
I am pretty sure it is animal cells and plant cells considering I learned that last year in 6th grade
Answer:
Option B, Biology requires that humans eat a certain amount each day, but culture teaches us what we want to eat, when we want it, and how to eat it.
Explanation:
As per biology, all living individuals require energy for doing their day to day activities and also to survive. This energy is obtained through food. Food provides essential nutrients and minerals and energy to the body that helps the body to survive, grow and develop.
Now a culture defines what to eat and how to eat for instance in some culture only vegetarian food is allowed and in some both vegetarian and non-vegetarian food is allowed for consumption.
Also the timing of eating are defined by the preachers of the culture.
Hence, option B is correct
