Answers
Answer:
option 1 and 4
Explanation:
It flows from high pressure to low pressure as air is made up of gases and gases move according to the process of diffusion.
It moves from lower density to higher density as pressure is inverse to density. As density is not what makes the air move it is pressure.

Answers
Answer:
it acts as products/reactants it acts to stablize the temperature
Explanation:
Dry heat sterilization is very useful to be used in materials that cannot come into contact with forms of heat sterilization such as steam. It is also widely used for objects that cannot come into contact with very high temperatures.
This type of sterilization is done by buckling, incineration, intra-red rays or hot air oven. In any case, it is important that the water is completely removed, both from the object and from the sterilization vehicle. This is because water is easily used by possible microorganisms to stabilize the temperature in their bodies, which can cause sterilization failures.

1. The calculation your performed is equivalent to the amount of energy released from eating
approximately 2.5 donuts. How long would someone need to walk to "burn" off the amount of
calories supplied by 2.5 donuts?
NEED HELP
ASAP
Answers
Answer:
3 hours.
Explanation:
An average donut has about 198 calories. In this case, 2.5 donuts would have an average of 495 calories (198 * 2.5).
1 hour of walking (2 mph) has the ability to burn about 183 calories. In this case, to know how many hours of walking it would take to burn the calories acquired by eating 2.5 donuts, we must do the calculation:
1 h = 183 calories
X h = 495 calories
X = 495/183
x = 2.70 h ----- 3 hours.

Which is the first step that geologists must do to compare rock layers at distant locations?
find the absolute age of rocks at both locations
compare a layer at one location to layers at other locations
identify index fossils in one or more layers at one location
collect fossils from different locations to study the organisms' lifestyles
Answers
Answer:
The correct answer is C
Explanation:
The first step a geologist would take in order to compare rock layers at distant locations is to Assign a date to the rock layers.
That is, they a relative age to a layer of rock at one point and then give the same age to matching layers at another point. By studying and identifying index fossils, geologists are able to match the rock layers.

On each step in Electron Transport Sustem chain, a small charge is given off that will be used to synthesize ATP in the process of phosphorylation. When the electrons leave the chain, in pris, they combine with oxygen (final acceptor) to form water. During this process water is and why:
A) oxidized because electrons are lost which produces oxidized water
B) oxidized because electrons are gained which produces oxidized water
C) reduced because electrons are gained which produces reduced water
D) reduced, because electrons are lost which produces reduced water
Answers
Answer:
C) reduced because electrons are gained which produces reduced water
Explanation:
The electron transport chain (ETC) involves a series of chemical reaction based on the reduction and oxidation of molecules. According to the question, the electrons that leave the chain combine with a final electron acceptor called Oxygen. This reaction is a reduction reaction because oxygen gains electrons.
The gaining of electrons by Oxygen reduces it to water (H2O). Hence, water is said to be reduced because electrons are gained by oxygen to produce a reduced form, called water.

The biotic potential of a population
A. directly dependent on the size of the population.
B. causes changes in death rates without affecting birth rates.
C. is the maximum rate at which a population may increase.
D. causes changes in birth rates without affecting death rates.
Answers
Answer:
C- is the max rate at which a population may increase
Explanation:
A population of living species to increase under environmental conditions.
The biotic potential of a population is the maximum rate at which a population may increase. Hence option C is correct.
The abiotic potential is the maximum rate at which a population can grow under ideal conditions, such as unlimited food, water, and space. It is determined by the species' reproductive rate and the number of offspring produced each breeding season.
The biotic potential of a population is not directly dependent on the size of the population. In fact, the biotic potential of a population is usually the same regardless of the size of the population.
However, the actual growth rate of a population will depend on the size of the population, as well as other factors such as the availability of resources.
The biotic potential of a population does not cause changes in death rates or birth rates. It is simply the maximum rate at which a population can grow under ideal conditions.
The actual growth rate of a population will depend on a number of factors, including the biotic potential, the availability of resources, and the presence of limiting factors.
Therefore option C) is the maximum rate at which a population may increase is correct.
