<span>Variations in asexual organisms are rather rare since they occur as a result of mistake of mitosis during DNA copying. On the other hand, variations in sexual organisms are a result of fusion of two different gametes that carry different traits. Thus, the offspring carries characteristics of both parents, resulting in greater genetic variation within the next generation. Consequently, sexual organism obtain greater genetic variation than asexuallt reproducing species.</span>
Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
A zoologist analyzes the jawbones of an extinct mammal and concludes that it was an herbivore. The zoologist most likely came to this conclusion based on the shape of the teeth.
Animals that consume plants, such as deer, elephants, cows, and many others, are known as herbivores. They eat a range of vegetables, fruits, grasses, grains, and other foods depending on the habitat of the specific animal, hence they are essentially vegetarians.
The broad, flat teeth of herbivores are perfect for chopping up the plant material they consume. These animals' teeth enable them to break down the fibers in their food, making it much simpler for them to digest.
Plant-eating animals known as herbivores have large, flat molars and sharp incisors. They don't own any dogs. The incisors, canines, and molars of omnivores are used for a range of foods. The teeth of herbivores are designed to crush and ground vegetation.

Answer;
-Nuclei acid
Explanation;
-Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.
-Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.
