Answer: Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. ... Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.
Explanation:
Answer:
An expression vector assists in expressing the gene into an mRNA and then into a protein by the process of transcription and translation respectively. In order to develop an effective expression vector, it should possess various essential organism-specific sequences so that they can articulate the desired gene.
For the process of transcription, a promoter is required, in order to understand the expression of a specific gene a selectable marker is required. While in prokaryotes, an RBS or the ribosome binding sequence like a Shine Dalgarno sequence is needed on the mRNA copy to initiate the process of translation.
Thus, it can be concluded that the researcher has missed out on the ribosome binding sequence due to which translation has not taken place.
Answer :
D) Plants
Explanation :
A producer is a plant or organism that produces it own food. Plants go through a process of Photosynthesis Which makes its own food.
Step 1 - All the reactants collect in the Chloroplast
Step 2 - Light energy from the sun drives the reactants to make a chemical reaction.
Step 3 - The products of the chemical reaction including Glucose the plants food and Oxygen, which is released into the air and which living organisms breathe.
Your Welcome! Good Luck!

Answer:
B) Competition
Explanation:
According to the statement, the farmer has planted <u>two species</u> that <u>requires same nutrients</u> for their <u>survival</u>, thus, they are competing with each other for nutrients acquisition only.
<u>Mutualism is not possible</u> because, in this interaction, <u>both species provides nutrients or other services</u> that are beneficial for each partner. Here, both species don't compete at all rather <u>they complement each other</u> for better survival and growth in nature.
Likewise, in <u>commensalism</u>, <u>one species provides benefits</u> whereas <u>other species doesn't provide any benefits neither cause harm</u> to the first species. In the given question, no beneficial partner is involved, and also there is no neutral interaction exists (both are competing).
Lastly, <u>parasitism is neither possible</u> here because it is an interaction where <u>any of the species starts eating the other species</u> directly for its growth and development. In this category, the fittest will survive and other species will die. In this situation, it might be possible that one species is more aggressive and could behave opportunistically but, still, it is not directly eating the other species (feeding biomass) for its own survival.
