40% solution is Hypoter to a 75% solution. Describe what would happen to a cell?
Answer: What will happen to a cell if placed in a hypotonic solution?
A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.
Explanation:
Suppose that 22% of an organism's genome is the nucleotide guanine (G). What else do you know about the organism
An organism's genome is made up of the nucleic acids and some other macromolecules. The genetic material is the DNA and the DNA comprises the nitrogenous bases, deoxyribose sugar and a phosphate backbone.
Suppose an organism genome is made up of 22% guanine, then approximately, the amount of cytosine is 22% and that of adenine and Thymine is 28% each.
According to Erwin Chargaff, he deduced that Adenine pairs with thymine therefore their base composition will be equal . And that cytosine pairs with guanine and the same follows. Since guanine is 22%, it follows that cytosine would be 22%, then their addition gives 44%. 100 - 44 = 56/2 gives the composition of either adenine or thymine which is 28% each.Learn more: https://brainly.com/question/19156457

Which of the following is a tongue-like structure that has backward curved teeth on its surface
A. radula
B. siphon
C. valve
D. nacre
The radula is a tongue-like structure that has backward curved teeth on its surface.
The radula is a structure with small curved or chitinous teeth, located in the mouth of all groups of mollusks except bivalves.
It consists of a tape-shaped membrane on which rows of teeth are arranged on its surface, it is supported by the odontophore (cartilaginous); it regenerates from its posterior portion.Its function is related to the feeding of organisms.
Therefore, we can conclude that the radula is a tongue-like structure that has backward curved teeth on its surface.

What do sediments increase pollution in an aquifer?
Answer:
Explanation:
Contamination also can occur from naturally occurring mineral and metallic deposits in rock and soil. For many years, people believed that the soil and sediment layers deposited above an aquifer acted as a natural filter that kept many unnatural pollutants from the surface from infiltrating down to groundwater.

sexual responses in both men and women are somewhat arbitrarily divided into three categories.
Intimate response is series of emotional and physical changes when making physical relationship. Men and women both experience four phases of intimate responses are excitement, plateau, ejaculation and resolution.
What are the phases of intimate response?The four phases of intimate response are:
Excitement: it can last from few minutes to hours.Plateau: it extends to the brink of ejaculation.Ejaculation: it is the climax of intimate response cycle.Resolution: body slowly returns to the normal state.Thus, the four phases of intimate response are excitement, plateau, ejaculation and resolution.

Mendel was the Father of Genetics, who studied the inheritance pattern and explained the independent assortment, segregation, and dominance. The influence of one gene does not affect the other in independent assortment.
The correct answer is:
Independent Assortment
The law of independent assortment states that alleles of two or more genes get sorted into gametes independently. The allele received for one gene does not influence the allele received for another gene.
The example of independent assortment includes the combination found in pea plants, such as round shape and yellow color, wrinkled shape, and green color, and round shape and green color.
Therefore, the correct answer is independent assortment.

What states and areas does the "California Floristic Province" cover?
Answer:
The California Floristic Province is a floristic province with a Mediterranean-type climate located on the Pacific Coast of North America with a distinctive flora similar to other regions with a winter rainfall and summer drought climate like the Mediterranean Basin. This biodiversity hotspot is known for being the home of the Sierran giant sequoia tree and its close relative the coast redwood. In 1996, the Province was designated as a biodiversity hotspot allowing it to join ranks among 33 other areas in the world with many endemic species. To be named a biodiversity hotspot, an area has to contain species and plant life that cannot be found anywhere else in the world. The California Floristic Province is home to over 3,000 species of vascular plants, 60% of which are endemic to the province.

Water is a source of ______________ for chemical reactions in cells. (a) hydrogen atoms (b) oxygen atoms (c) energy Both (a) and (b) (a), (b), and (c).
Answer:
A) Hydrogen Atoms
Explanation: Water provides hydrogen (H) and (O) atoms for making biological molecules.
Water is a source of both (a) and (b) for chemical reactions in cells. Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side which participate in chemical reaction.
what are the features of water molecule ?
Water is tasteless, odorless, or transparent, where oxygen atom having nucleus attracts electrons more strongly than the nuclei of the hydrogen atoms.
So oxygen is more electro negative and electron-greedy than hydrogen atom, resulting in the development of a partial negative charge on the oxygen atom of the water and a partial positive charge on the hydrogen end.
Water shows both cohesive and adhesive properties where adhesion of water molecules refers to stick to some other substance while cohesion is the property of water molecules to stick together.
