Answer:
1) Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in.
2) Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.
Explanation:
Answer:
this mean the certain number of organisms an ecosystem can hold without being overrun and potentially destroyed.
Answer:
Most likely B
Explanation:
A - Carrying capacity is the amount of a species that can live in a given area with the given resources, weather does not apply.
B - Limiting factors are things such as food, mates, and competition with other organisms for resources, which can limit the maximum population. Temperature can be applied here, it is the best option.
C - Climax community is when an area's ecosystem is stable, so the term makes no sense used here.
D - To be honest I have no clue what this is. But making an assumption from the term, the winter being "unusually cold" does not make it a "pattern". So I don't think it's this option. I could be wrong, but I assume this is not the right choice.
The sequence of the mRNA complementary strand for the given sequence of the strand will be 'AUG CUU GAG GGG UCC'.
The name of the decoding process is translation, and ribosomes are involved in this process.
The process of the synthesis of protein begins with the process of transcription. In this process, the DNA is unwinded, and the RNA polymerase binds to the promoter region and transcribes the codon corresponding to the amino acids. The transcribed mRNA strand is then translated by the ribosomes. The ribosomes reads the codons and the tRNA brings and attaches the related amino acids in a sequence resulting in the formation of a protein.
The protein synthesis is crucial as the proteins are responsible for the structure and functions of the different cells of the body.
Sickle cell anemia is a genetic disorder, in which a point mutation changes the codon for the glutamic acid to valine. This leads to the formation of an abnormal shape of the hemoglobin which decreases the ability of it to efficiently transport oxygen.
