Which statement best explains what happens to a leaf when it has lost much-needed water?
Answer:
its turgor pressure decreases
Explanation: This is also important because this function regulates water loss within the plant. Lower turgor pressure can mean that the cell has a low water concentration and closing the stomata would help to preserve water. :-)
When a leaf loses much-needed water, its turgor pressure would decrease. Hence Option A is Correct
What is Turgor pressure ?Turgor Pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.
When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.
Thus, the turgor pressure created by the presence of water is lost by the absence of water.
The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

Las Vegas Raiders' running back Josh Jacobs is 72 inches tall and has mass of 100 kg. Los
Angeles Rams' defensive tackle Aaron Donald is also 72 inches tall but has a mass of 130
kg. Josh runs the ball East, towards the goal line, quickly traveling 50 yards in
5.5 seconds. Josh then accelerates towards the goal line at 9 m/s2. Aaron accelerates
West, the exact opposite direction, towards Josh at 6.5 m/s2. They both meet with an
explosive collision at the 1 yard line.
In a paragraph, address the following questions. Calculate numerical answers to the
nearest hundredth and correct units must be included.
1. What is Josh Jacobs' speed?
II. What is Josh Jacobs' velocity?
III. How much force does Josh Jacobs create?
IV. How much force does Aaron Donald create?
V. By calculating the net force, does Josh Jacobs score the touchdown.
Explain why or why not?
Answer:
Josh is running at a speed of 9.09 yards per second.
Josh's velocity is 9.09 East.
Josh's force is 900 N.
Aaron Donald's force is 845 N.
Yes Josh scores the touchdown because he is faster and has more mass than Donald.
Explanation:
Josh scores the touchdown as he is heavier and faster than Donald.
Formulas are:
Force= mass x acceleration
Speed= distance divided by time.
Velocity= distance divided by time.

The ability to exert a force that causes an item to move is what is meant by the definition of energy as the "power to accomplish work." Even though the definition is unclear, the meaning is clear: energy is simply the force that moves things. Potential energy and kinetic energy are the two categories of energy.
Which source of energy has a direct impact on climate change?Renewable energy is frequently cited as the most important shift the world can make to fend off the worst consequences of global warming. This is due to the fact that renewable energy sources like solar and wind don't produce greenhouse gases like carbon dioxide, which contributes to global warming.
Wind, sunlight, bioenergy (organic matter burned as fuel), and hydroelectricity, including tidal energy, are a few examples of renewable energy sources.
The ability to exert a force that causes an object to move is what the definition of energy as "power to accomplish work" refers to. Despite the ambiguity of the definition, the meaning is clear: energy is simply the force that moves things. The two types of energy are potential energy and kinetic energy.

Calculate the atoms of hydrogen in 52.0 g of H2O.
Answer:
34.81 ×10²³ atoms
Explanation:
Given data:
Mass of water = 52.0 g
Number of atoms of hydrogen = ?
Solution:
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 52.0 g/ 18 g/mol
Number of moles = 2.89 mol
1 mole of water contain 2 mole of hydrogen.
2.89 mole of water contain 2.89× 2= 5.78 moles of hydrogen.
Number of atoms of hydrogen:
1 mole = 6.022×10²³ atoms
5.78 mol × 6.022×10²³ atoms / 1mol
34.81 ×10²³ atoms

traveling 20 km in 2 hours. Show the
formula, and your work with the correct
units. HELP PLEASE AND HURRY
Answer:
10 km/hr
............
The speed of a bicycle is 10 km/hour or 0.27 m/sec.
What is the Speed?The speed may be defined as the rate of change of position of an object in any direction. It is significantly measured as the ratio of distance to the time in which the distance was covered. Speed is a type of scalar quantity that has only direction but no magnitude.
According to the question, the distance traveled by bicycle = 20 km or 2000 meters.
The total time is taken = 2 hours or 7200 seconds.
Now, the formula for calculating the speed is as follows:
S = Distance/ Time = 20km/2 hours = 10 km/hour.
S = Distance/ Time = 2000 meters/7200 seconds = 0.277 m/sec.
Therefore, the speed of a bicycle is 10 km/hour or 0.27 m/sec.

Will sodium displace iron from iron oxide?
Answer:
Explanation: A more reactive metal will displace a less reactive metal from a compound. The thermite reaction is a good example of this. It is used to produce white hot molten (liquid) iron in remote locations for welding. A lot of heat is needed to start the reaction, but then it releases an incredible amount of heat, enough to melt the iron.
aluminium + iron(III) oxide → iron + aluminium oxide
2Al + Fe2O3 → 2Fe + Al2O3
Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide:
Answer:
Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:
Explanation:
a more reactive metal will displace a less reactive metal from its compounds
Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:
the more reactive metal gradually disappears as it forms a solution
the less reactive metal coats the surface of the more reactive metal
For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:
the blue colour fades as colourless magnesium sulfate solution forms
brown copper coats the surface of the magnesium
I hope this is correct or answers your question :)
