Passive transport can be explained by which
statement?
Particles move randomly.
O Energy is used to move particles.
o Large particles can move into cells.
Particles are moved to areas of higher
concentration.
Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
Answer:
The correct answer is A " particles move randomly "
Explanation:

How is the rate of photosynthesis measured
Explanation:
The incoming and outgoing CO2 from the leaf chamber is measured by infrared spectroscopy with an infrared gas analyzer. The difference gives us the amount of CO2, from which the rate of photosynthesis can be calculated.
Which of the following best explains the way that a molecular clock can be used
A: The number of DNA mutations in an organism is measured over time to determine how long it’ll take for a new species to evolve
B: The number of DNA mutations in a species is compared to the number of DNA mutations in another species to determine the relative amount of time each species have been evolving
C: The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the years of evolution that separate the two species
D: The number of differences in the DNA sequences of two organisms of the same species is average to determine how many years of evolution have occurred
how will relative humidity relate to the temperature of the wet bulb thermometer
Answer:
At 100% relative humidity, the wet-bulb temperature is equal to the air temperature at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.
11. Why is the age of the earth important to Darwin's theory of evolution?
Answer:
Darwin's theory of evolution is when species are taking time to evolve from the original organism so in order for this to happen there has to be an original species so he also said that we came from apes if the world was 200 years old that still wouldn't be enough time for us to evolve how he said so in order for his theories to be even remotely correct it took time for this to happen so the age of the earth in a way helps support his theory

What two things below most affect the amount of dissolved oxygen in water?
Answer:
Dissolved oxygen levels will fluctuate with temperature
Explanation:
While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these factors interact.
What happened when two forces act in the same direction
Answer:
They repel one another. I think
Answer:
When two forces act in the same direction a few things can happen such as...
Explanation:
If the two forces are equal then there will be no movement but it the two forces are different, one being stronger the the strong one will over power the weaker one and the motion will move against it the weaker one causing it to move in the direction of the stronger, and of course there will be a bit of resistance.

During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?
chemical energy originally stored in the glucose molecule
potential energy from the difference in the concentration gradients of the cell
kinetic energy generated by the chemical reactions
electric current created during the destruction of electrons in the glucose
Answer:
1.Sugar bonds
2.Transport proteins
3. Digestion
4. Oxidation
explanation
Chemical energy is stored in the bonds of sugar.
The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.
Digestion converts chemical energy into kinetic energy used by cells.
When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.
Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
Answer:
A. Chemical energy originally stored in the glucose molecule.

Which of these activities would be least likely to help scientists explain the origin of life on Earth? determining how pollution is affecting life in the ocean
determining how the atmosphere became rich in oxygen
determining how cells could develop from nonliving matter
determining how organelles developed from symbiotic organisms
Answer:
B
Explanation:
Determining how the population affects life in the ocean is the least likely to help scientists explain the origin of life on Earth. Therefore, option A is correct.
What is the origin of life?The origin of life means the emergence of organisms on earth. Many scientists tried to explain how life originated on the earth and gave various theories, like panspermia, common descent, gradualism, natural selection, etc.
The first organism that originated on the earth was microbes in water. When the earth formed, it was reduced in nature. Gradually oxygen formed on the earth which was very helpful in the origin of life. Some theories explained how cells could develop from nonliving matter.
determining how the population is affecting life in the ocean is not related to the origin of life. Hence, option A is correct.

The provided question is incomplete as the important part and group of choices was missing, however, the correct question is given below:
In an experiment, Tony placed a potted plant under a bell jar, completely sealing the jar to the tabletop. After placing a box over the bell jar for 24 hours, he measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement best describes the measurements he would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
Concentrations of both carbon dioxide and oxygen decreased.
Concentrations of both carbon dioxide and oxygen increased.
Carbon dioxide concentration increased; oxygen concentration decreased.
Oxygen concentration increased; carbon dioxide concentration decreased.
Answer:
The correct answer would be - Carbon dioxide concentration increased; oxygen concentration decreased.
Explanation:
There are two major processes respiration and photosynthesis that help in the production and utilizing the carbon dioxide and oxygen in plants. In order for your plant to grow photosynthesis is the process that converts carbon dioxide into glucose and oxygen. Photosynthesis only occurs in the daylight process so the use of carbon dioxide and producing oxygen is limited.
On the other hand, respiration is a continuous process that uses oxygen and glucose to produce carbon dioxide therefore the correct answer is Carbon dioxide concentration increased; oxygen concentration decreased
