Answer:
option C
option C
Explanation:
we know that gravity is strongest when two large objects are near each other--so, when the asteroid reaches point C (which is shown to be closest to the sun), the pull of gravity will be greatest.
We also know that the attraction/pull of gravity slows down objects, so, the asteroid will be going slowest at its point of strongest gravity--which we have determined to be point C
hope this helps! let me know if you need more explanation, have a lovely day :)
Answer:
the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.
Differences:
- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from
- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases
- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors
Explanation:
Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:
1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.
2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)
3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.
None of the answer make logical sense except overfishing.
The correct option is D.
A natural law refers to a description of natural event that has been proved to be true without exception. Such a law usually generalizes a body of observation but can not explain why the observation occur. An example of a natural law is Newton's law of gravity, he observed that an object thrown up usually come down but can not explain the reason behind this observation.
Answer:
H=1hump
h=2humps
possible genotypes: HH Hh Hh hh... 1/4 chance they produce a camel with 2 humps.
u got to make a punnet 2×2 square. put one parent on top and one on the side. it makes it easier to solve.
