Answer:
Brain cells are very sensitive and when they do not have oxygen they slowly start dying off which leads to brain damage.
Explanation:
Glycolysis produces important electrons and ATP which allow cellular respiration and fermentation to occur.
Brain produce ATP by glycolysis is the only process to generate energy, if anaerobic condition brain cells get dead.
What is fermentation?Since oxidative phosphorylation cannot make ATP in the absence of oxygen, glycolysis takes over as the cell's main source of ATP.
Because it supplies cells for the glyceraldehyde-3-phosphate dehydrogenase reaction, which comes before the steps that produce ATP, lactic acid fermentation is significant.
The adult brain only has a finite quantity of anaerobic glycolysis energy and time to sustain ion homeostasis and other vital activities before multiple events take place that cause brain cell damage and death.
Therefore, brain cells only depend on aerobic glycolysis for energy production.

CO2 increases global warming temp the most followed by CFCs ( chlorofluorocarbons) which are used in refrigerators and ACs but now banned.
The movement of waves in the middle of the ocean is normally
static
vertical
circular
horizontal
Answer:
Vertical
Explanation:
Since we are talking about movement, and the ocean can't be static due to many things happening around and inside it can't be static.
It is not circular and not horizontal. It is vertical. The movement of waves is vertical and this is because waves don't move up and down but vertically since wind is the usual maker of waves in the middle of the ocean.

The cell membrane has____. a) polar heads on the outside and nonpolar fatty acids on the inside b) nonpolar fatty acids on the outside and a polar heads on the inside c) polar heads on both inside and outside d) nonpolar fatty acids on both inside and outside
Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.

O cartilaginous joints
o fibrous joints
o synovial joints
O ball-and-socket joints

Explanation:
There is no cavity, or space, present between the bones and so most fibrous joints do not move at all, or are only capable of minor movements.
7. Products like "Tums" neutralize stomach acid because Tums is a a. neutral. b. base. c. acid.
Answer:
(B) Products like "Tums" neutralize stomach acid because Tums is a base.
Explanation:
If the product neutralizes an acid, that means it must be a base. Acid + Base = Neutral. If you were to consume an product that is acidic, the stomach will end up being overly acid, which is unsafe for the body. If you were to consume a product that is neutral or "normal", the product would not do as much to neutralize the stomach acid, compared to a more basic pH. Tums has a main ingredient of calcium carbonate, CaCO3, a base. This ingredient helps regulate the pH levels for your stomach so that it does not become too acidic.

Explanation:
A rock has been sent on a journey down through the layers of the Earth until it reaches the inner core. Explain what happens to the atoms in the rock as it moves through each layer.
Answer:
The rock components of the crust are slowly but constantly being changed from one form to another and the processes involved are summarized in the rock cycle (Figure 3.2). The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.The rock cycle is still active on Earth because our core is hot enough to keep the mantle moving, our atmosphere is relatively thick, and we have liquid water. On some other planets or their satellites, such as the Moon, the rock cycle is virtually dead because the core is no longer hot enough to drive mantle convection and there is no atmosphere or liquid water.
