Answer:
When an organisms reproduces asexually its offspring is identical, this means it has the same DNA code.
For example viruses look for specific protein types at cell membranes to "anchor" or "stick" and then inject their genetic material. If all the individuals of a population have the same membrane proteins the whole population is vulnerable to be infected by the virus.
Sexual reproduction creates genetic variability due to mechanisms like crossing over and the assortment of chromosomes during meiosis. On top of it, different parents contain different information which leads to offspring with similar but different characteristics which can end up having different membrane proteins that can save them from the virus.
It theorizes that the universe is constantly expanded, in other words getting bigger.
Different colored bands in each solvent signify the different materials that are found in the substance that is been analysed.
The green band in the solvent represent the green chlorophyll which are found in leaves. Chlorophyll is the substance which gives the plants the capacity to trap energy from the sun for production of food.
Answer:
The correct answer is - "is this factor decreasing the population growth rate in the environment?".
Explanation:
When a factor or resource in the environment causes the decreases or lowers the population growth rate, such factors known as the limiting factors. Limiting factors can be lower food resources, higher competition, lower birth rates, higher death rates, and many other factors.
Thus, the correct question should ask about the limiting factors that are affecting the monarch population would be - "is this factor decreasing the population growth rate in the environment?".
