Water can only evaporate when it is heated. When water is under heat, the water molecules vibrate and move around so quickly that the molecules escape into the atmosphere. The molecules become less and less dense as they float into the air.
which kind of electrical charge is found on a hydrogen atom of a polar water molcule?
Answer:
he two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction

What is the function of the hydrogen ion concentration gradient?
Answer:
Notice the large difference in the number of hydrogen ions on the two sides of the membrane. This difference is a hydrogen ion, or proton, concentration gradient. The energy associated with this gradient is used to synthesize ATP from ADP and Pi. This occurs at the ATP synthase complex.

14. Cells in heart require large amounts of energy because the heart never stops beating. Because of this, the cells in heart require a larger number of –
A nuclei B mitochondria C vacuoles D lysosomes
Answer:
B. Mitochondria
Explanation:
Mitochondria is the cell’s powerhouse, these organelles are the main suppliers of energy without these organelles; nutrients are unable to be converted to usable ATP which is needed for many vital jobs including cAMP mediated transport. In addition, when looking at histology, tissues with many mitochondria organelles, which looks like spots, will most likely be muscle tissues.

Would you design cars with different masses or equal masses? Would you design your cars with high speeds or low speeds? Use Newton's Laws of motion to support your response.
Answer:
You can actually apply the same concept, obviusly you want the cars to be the same weight, and you want your cars to be not too fast, because of the same equation F=MA if the car is faster, is because it has higher acceleration, wich results in higher impact force.

because i had this test and got it wrong. its A.
Diabetes can be a very chronic disease if not properly controlled, it mostly affect the aged people. If not properly treated it can in some cases lead to the death of the individual.
Diabetes occurs when the pancreas in the body system does not produce any insulin, the insulin is a type of hormone that is found in the body, this hormone helps to normalize the amount of blood sugar that is present in the human body.

Which weather patterns are caused by atmospheric pressure differences?
Answer:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies.
Explanation:
Storms, which are severe weather conditions, develop when air pressure differences speed up air flow.
What do you mean by atmospheric pressure differences ?It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. Weather is predicted by atmospheric pressure. There will often be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.
Air density variations, which are connected to temperature, are what are causing this shift in pressure. Because heated air's gas molecules move faster and further apart than cooler air's, warmer air is less dense than colder air.
Thus, various weather patterns are seen with change of atmospheric pressure.
