Explanation:

now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.

The two types of cells found in the human body are blood cells and immune cells.

Cells are the fundamental foundations of all life. Trillions of cells make up the human body.

They support the body's structure, absorb nutrients from food, repurpose those nutrients into energy, and perform specialized functions.

Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic compounds found in all cells.

A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.

The cytoplasm contains complicated accommodations of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.

Thus, there can be many cells in a human body, the most important perhaps are blood cells and immune cells.

CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.

Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.

The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

Answer:

b. any base pair can pair to any other base

Explanation:

Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.  

• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.  

• The majority of the DNA is present within the nucleus of the cell.

• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.  

• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.  

• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate  and sugar.  

• Together, a phosphate, base, and sugar are known as a nucleotide.  

Thus, statement B is incorrect.

Answer:

Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.

The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.

Explanation:

The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.

The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.

When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.
