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.

Explanation:
Hope this helps please mark brainliest
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.

Explanation:
Answer:
7amu
Explanation:
Atoms are composed of three particles. The proton, neutron, and electron.
The mass of the atom in amu is just the number of protons and neutrons in the nucleolus since they both have a mass of about 1 amu. Electrons are not counted since they have an incredibly small mass that ultimately does not matter.
This atom has 3 protons (positively charged particle) and 4 neutrons (particle with no charge) which together gives a mass of 7 amu.

Answer:
Even though plants are rooted in the ground, they still move, exert force, and do work.
Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.
When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.
When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

WHAT DOES THE MASS OF AN OBJECT MEASURE HURRYYYYYYYYYYYYYYYYYYYYY
Answer:

Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Magnesium is a metal that is commonly used in products that need to be lightweight. Suppose a 2.00-kg piece of magnesium has 8160 J of energy added to it. Its temperature increases 4k. What is the specific heat of magnesium. Show your work
Answer:
The specific heat of magnesium is 1.02 J/g.K
Explanation:
To calculate the energy involved in the heating of the metal (magnesium), we use the following expression:
energy = mass x Cp x ΔT
We have the following data:
mass = 2.00 kg x 1000 g/1.00 kg = 2000 g
energy = 8160 J
ΔT = 4 K
Thus, we can calculate the specific heat of magnesium (Cp) in J/g.K as follows:
⇒ Cp = energy/(mass x ΔT) = 8160 J/(2000 g x 4K) = 1.02 J/g.K

Calculate the speed of a bicycle
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.

Synthesis Reactions
Decomposition Reactions
Single Replacement Reaction
Double Replacement Reaction
Combustion
Then explain, in a general sense, how you will determine which of the above types of reactions are occurring in your experiments.
Answer:
.
Explanation:
-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.
-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)
-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise
-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product
-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O
A chemical reaction may involve one or more reactants to yiled one or more products.
Types of reactionsBelow we are going to discuss the types of reaction under the following headings;
Synthesis reaction - This is a reaction in which two or more substances come together to yiled a single product.
Decomposition reaction - This involves the breakdown of a substance into new substances.
Single Replacement Reaction- This is a type of reaction in which an atoms replaces another in a compound.
Double Replacement Reaction - This is a reaction in which cations exchange anion partners in a reaction
Combustion - This is a reaction in which a substance is burnt in oxygen.
