The invading bullfrogs ARE HARMFUL. This is because, they cause decline in the population of the native species.
Decline in the population of the native species will throw the ecosystem into a condition of imbalance which will eventually affect all the living organisms that are living in that ecosystem.
Answer: A. The genes encode resistance to antibiotics.
D. The genes are carried on plasmids
F. The "clock"genes are highly mobile between species.
Explanation:
Molecular clock is a tool that is used to calculate the time of the evolutionary events. These are the gene sequences that are used to determine the evolutionary distance between the new and primitive organisms developed on earth. It also measures the random changes just like mutation. Thus the molecular clock is also called as the gene clock or evolutionary clock.
The accuracy of the molecular clock can be increased by the genes that encode for a resistance against the antibiotics, the genes that are carried on the plasmids and the clock genes which are highly mobile among the species.
The simulation supports the scientific law : I.e TRUE
<h3>The scientific law of conservation of mass</h3>
The scientific law of conservation of mass states that the mass of a substance remains the same in a closed system as the substance/matter undergoes a chemical reaction. during chemical reaction the matter changes from one form to another. Therefore measuring the mass of matter in an object before it undergoes a chemical reaction support the scientific law as the mass of reactants is equal to mass of product.
Hence we can conclude that the simulation supports the scientific law : I.e TRUE.

The answer is D because <span>In </span>exocytosis<span>, materials are </span>exported<span> out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones.</span>
