Answer:
Only first 1 requires energy, rest all are passive transports!!Explanation:
First one:Here the molecules are moving from region of low concentration to high concentration, so as it is an uphill transport also known as Active transport. So active transport requires the ATP to be carried out.
Second one:This is the normal passive transport of hydrophobic or lipid soluble substances. So as normal passive transport requires no energy but a concentration gradient. So it doesn't require the ATP to be carried out.
Third one:This is a transport system of protozoans like Amoeba which form a pseudopodia process around the food, and then engulf the substances which then is surrounded by vacoule for digestion to take place. It also doesn't require energy.
Fourth one:This is an example of bulk transport mechanism where large big molecules move from higher concentration to their lower concentration through special membrane proteins and then their utilisation takes place. This is also known as Endocytosis. This also doesn't require energy to be carried out.

False
Answers
Answer: False
Explanation: A perfectly circular orbit would mean that the earth is always the same distance from the sun
Answer:
Earth's orbit is not a perfect circle
Explanation:
Earth's orbit is not a perfect circle. It is elliptical, or slightly oval-shaped. This means there is one point in the orbit where Earth is closest to the Sun, and another where Earth is farthest from the Sun. The closest point occurs in early January, and the far point happens in early July

if a ball goes at 135 mph,how fast will it travel over a year?
Answers
Answer: I will travel fast in a year I guess
Explanation:
Answer:
The optimum number is a 1:1.5 ratio between clubhead speed and ball speed. ... In other words, at 100 mph of clubhead speed, a solid blow will send the ball at 150 mph off the face of a legal driver. The lower the ratio, the poorer the quality of the strike and the more inefficient the impact.

Why is it harder for evaporation to occur when the air pressure is high?
A) Evaporation only occurs when there is no air pressure.
B) The air particles are heavier with little ability to rise.
C) The air particles are packed together with little space for water vapor.
D) The air particles are spread out with plenty of empty spaces for water vapor.
Answers
Air pressure has a few effects on evaporation. If the air pressure is high on the surface of a body of water, the water will not evaporate quickly. The pressure on the water makes it very difficult for the water to disperse as a vapor into the atmosphere. Air pressure is the force of the surrounding air that is acting on the surface of the water. Greater air pressure means greater force per unit area. This pressure is forced on evaporating water molecules, so greater air pressure means that the water molecules will exert more energy to evaporate. That being said, you could say the air particles are heavier and weighing down on the water. I hope this helps! Have a great day. :)
