A catalyst speeds up or initiates a chemical reaction. Please mark Brainliest!!!
When an energy source is renewable it is able to be continuously used without end and it usually does not harm the environment. <span />
1. Am invasive species is not apart/native to a specific area and could potentially cause damage to the environment and in some cases human health.
2.Invasive species can be found anywhere, considering that they are not native to an area.
3. Many invasive species form interactions with pollinators, DIRECTLY, and even though this isn’t necessary to the invader, pollinators are the direct role because they play a part in plant invasion, basically meaning they could damage the plant greatly. More direct consequences could be competition.
4. An example of INDIRECT consequences would be via a multi species. Like for example, effecting a certain species just to get to another species, diversely.
5. There are many ways that an invasive species could be introduced mostly by people however.
Part a- A vector is a specific organism that by itself couldn’t spread a certain disease, but by pathogens
Part b- A pathways is different from a vector however because it is along with molecules. These molecules could lead to change in a cell or potentially damage.
Hope this helps! :)

Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is <u>C.There are not enough nucleotides available to construct new DNA.</u>
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
