Answer:
can lead to natural selection
Explanation:
<h2>
</h2><h2>
Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>
This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "<u>Nature selected"</u><u> </u>the better fit organism.
Answer:
Explanation:
When a substance has the capacity to disrupts the genetic compositions (DNA) of the organisms, to the extent that it makes the particular organism genetic materials prone to genetic mutation,( random changes in the genetic composition) such group of substances are called Mutagens.
ionizing radiation,radioactive decay are some examples of of physical mutagens, while biological mutagens examples include viruses and bacterial. Chemical mutagens are Benzene compounds,bromine,aromatic amines,sodium Azide.
They exerts their negative effects
by disrupting gene expression sequence of transcription, translation, or changed the nucleotides sequence of the DNA leading to deletion, addition, subtraction of genetic bases.Some may make chromosomes to be unstable, disrupting the structure
Although some mutagens can cause cancer, that is they are mutagens. not all mutagens carcinogenic.This is because the Mutagenic effects depends on the metabolites present in the cells of the organisms.
Answer:
The initial purpose for building the canal was to shorten the distance ships had to travel between the Atlantic and Pacific Ocean. It enabled shippers to cheaply transport different types of goods within a short period of time
Answer: B)
Explanation:
The glycoprotein and glycolipid carbohydrate chain forms the hydrogen
bond with water molecules to help stabilize the membrane structure.
When it comes to glycoproteins and glycolipids and their bond we can say that their carbohydrate chain is forming a hydrogen bond with water molecules that are surrounding the cell and thus. In this case, they are helping in the stabilization of membrane structure. They are used as receptor molecules.
Answer:
he path taken by the nerve impulses in a reflex is called a reflex arc. Reflexes do not require involvement of the brain, although in some cases the brain can prevent reflex action.
