The answer is Energy Pyramid. The energy pyramid is a graphical model of energy flow in a community. The different levels represents different groups of organisms that might compose a food chain. From the bottom-up, they are as follows;
Producers- bring energy from nonliving sources into the community, primary consumers eat the producers, which makes them herbivores in most communities, secondary consumers eat the primary consumers, which makes them carnivores and tertiary consumers eat the secondary consumers.
Answer:
Deletion mutation usually takes place due to the errors in the process of DNA replication . DNA polymerase slips off on the template strand due to which that part of the DNA is not coded in the daughter strand.
It can skip from one nucleotide (point mutation) to an entire gene. Point deletion can result in frame-shift mutation if it takes place in the beginning or middle of the gene. However, if it takes place at the end of the gene then it may cause no harm.
For example, let us assume the original sequence of DNA as ATG-AGT-CGT-ATA-TAA. It will result in the formation of methionine, serine, arginine, isoleucine, and STOP codon.
Point deletion at the end of the gene results in ATG-AGC-GTA-TAT-AA sequence. Now it will code for methionine, serine, valine, and tyrosine as AA will not code for anything. Hence, the sequence of the protein remains the same.
Hence, if deletion mutation takes place at the last or stop codon of the gene then it will cause no harm or change in the protein sequence. However, if it takes place before that then it may result in frame-shift mutation and thus a mutated protein.
What is an introduced species ?
A. A species that is a poor predator
<u>B. A species that does not normally live in an area
</u>
C. A species that has no permanent home
D. A species that increases biodiversity
Answer:E.
Explanation:The MMR mostly affects children and if not administered vaccine in time to save a respond that prevent subsequent reoccurence of infection, it will lead to severity of infection (secondary infection ) probably if resurfaced at adult stage.
The end result is having two identical daughter cells.
