Explanation:
The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration
Through transpiration, plants move enormous quantities of water from the soil to the air.
Transpiration is the process by which plants lose water vapor through small openings called stomata in their leaves. Water is taken up by the roots from the soil and transported to the leaves through the xylem vessels. Once in the leaves, water evaporates from the surface of the cells and exits through the stomata into the surrounding air.
This continuous loss of water through transpiration creates a pulling force, known as the transpiration pull or tension, which helps to draw water upward from the roots. As water molecules evaporate from the leaves, more water is pulled up through the plant's vascular system to replace the lost water.
Transpiration not only aids in the transport of water and nutrients from the roots to the rest of the plant, but it also plays a crucial role in regulating the plant's temperature, maintaining cell turgidity, and facilitating the movement of minerals within the plant.

How is bacteria are different from animals?
Answer:
Bacteria has 1 cell and An Animal has multiple cells.
Explanation:
Bacteria is a cell its self. While An Animal, It has multiple cells that create multiple tissues, and those tissues create multiple organs, those organs make up an organ system. After the Organ System, it's an organism.
Organism = Animal, Human, Ect.
Meanwhile, Bacteria is made up ONE CELL (bacteria it's self is 1 cell)
So the answer is "Bacteria has 1 cell and An Animal has multiple cells."

Difference between pulley and wheel and axle..
Explanation:
Difference between pulley and wheel and axle are:
pully = A pulley is a circular disc that has a groove around the circumference over which a rope or string can move. In the pulley, load is connected to one end of the rope and effort is applied on the other ends . The pulley that does not move up and down is called the fixed pulley.
Wheel and axle= Wheel and axle consists of two cylinders of different radii. The cylinder of large radius is called wheel and the cylinder radius is called axle . Both wheel and axle move together under the application of effort.
I have send you a photo of wheel and axle, pulley.

How does the density of one marble compare with the density of six of the
marbles?
Answer:
Since, density is mass per unit volume, the density is the same.
The density of the marbles will depend upon their mass and volume, not on their count.
What is the density?The density of an object is measured as the mass per unit volume. The average density equals the total mass of the object divided by its total volume.
The formula of the density of the material is expressed as follows:
Density = Mass/Volume
The S.I. unit of the density is Kg/m³. The density of a material is an intrinsic property as it doesn't depend on the size. If the size of the object increases, the mass increases as well but the density of material remains constant.
If the density of each marble is the same then the density of six marbles will be the same as the one marble because the density of marble is an intrinsic property. The density of marbles does not depend upon the number of marbles.

GIVING 20 POINTS!! Apply Concepts Two chemists each plan an investigation in which they will combine hydrogen gas with chlorine gas to observe the chemical reactivity. The plans differ in that one will use 25 milligrams each of hydrogen and chlorine, and the other will use 1000 times this amount, i.e., 25 grams each of hydrogen and chlorine. Can the investigations reach similar conclusions about the reactivity of hydrogen with chlorine? Explain.
Answer:
Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2
Explanation:
1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios. This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction
2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.
3. A reaction with more reactants will need more care because more products are produced, which can be toxic
4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound

What were the changes to the atomic model over time?
Answer:
The atomic model started out as a large single ball, then with electrons attached to it. It then became "planetary model" with electrons orbiting at specific levels, and then later one with a nucleus or multiple different particles like protons and neutrons, and electrons orbiting at general (but not specifically predictable) areas.

The energy level of an element is the region around the nucleus where its electron is likely to be, this corresponds to the period of the element in the periodic table.
Elements found in period 1, have one energy level.
Elements found in period 2, have two energy level.
Examples of elements found in period 2 include:
lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neonIn the given options, only option B contains two elements with 2 energy level.
