NEED HELP ASAP! WILL MARK BRAINLIST 1 - How does frost form?
A) When the dew point is below freezing, and the air temperature reaches the dew point, frost forms.
B) Objects that are below the freezing point of water, attract and freeze water vapor in the air.
C) When water droplets come in contact with objects that are below freezing, frost forms.
D) Water must first condense into liquid water, and then freeze into a solid to form frost.

2 - In what ways is water stored on Earth?
A) condensation, rainfall, snowfall
B) ground-water, lakes and rivers, atmosphere, ice
C) sublimation, transpiration, evaporation
D) ground water discharge, snowmelt runoff, surface runoff

3- If the relative humidity is 80% and the temperature is 90° F what happens if the temperature increases to 100° F?
A) The relative humidity increases.
B) The relative humidity drops.
C) The relative humidity doesn't change

4 - Which processes help return water to the oceans and lakes?
A) water storage in ice, snow, atmosphere and ground
B) photosynthesis, condensation, infiltration
C) evaporation, transpiration, sublimation
D) snowmelt, streamflow, ground-water discharge

its b cause water vapor rises and when it does its possible to freeze and become frost

Explanation:

First question the answer is: A When the dew point is below freezing, and the air temperature reaches the dew point, frost forms.

Second question answer  is: B. ground-water, lakes and rivers, atmosphere, ice.

Third question answer is: B. The relative humidity drops.

Fourth question answer is: C. evaporation, transpiration, sublimation.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

i believe the answer is c
