Explanation:
well a mutation in my opinion is genetic change that happened in the animal this could be beneficial or may not be. natural selection is a process that ensures only the best of the species survives and more of them will produce because all of the flawed ones will die off. adaptaion is when a plant or animal adapts to its surrounding over time they may develop a charterisric that will help them thrive. all of them tie togethor
Answer:
sympatric speciation
Explanation:
Species of fruit fly larvae in the genus Rhagoletis each feed on a particular kind of fruit. Rhagoletis pomonella feeds on the small red fruit of the hawthorn tree. In 1865, farmers in the Hudson River valley found that R. pomonella flies had begun attacking their apples and then spread to apple orchards in adjacent areas of Massachusetts and Connecticut. These now separate varieties of flies, the apple and haw flies, usually don't interbreed with each other because their periods of mating coincide with the different ripening times of apples and hawthorn fruit. Each variety is becoming specialized to feed and reproduce in its own particular microhabitat and may be transitioning to separate species.If the apple and haw flies become distinct enough to be separate species, their evolution is an example of sympatric speciation
Answer:
The correct answer is - 24, 24
Explanation:
In any type of cell division, there is an interphase stage before the actual process of division which is a preparatory process or stage that includes different substages like G1, S, and G2. S phase is a synthesis of the cell cycle responsible for duplication or replication of the DNA.
So, at the end of the S phase, the DNA amount becomes double its initial amount and remains the same in the G2 phase. So, if the initial amount is 12 picogram then it will be double in the S phase and remain 12 in G2 as well.
Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
