Answer:
mantle
Explanation:
The mantle is very thick: 1800 miles deep. The mantle is a little bit like a sandwich. On the top and bottom parts of the mantle, the rock doesn’t move very much. In the middle of the mantle is the asthenosphere. This part of the mantle moves around fairly slowly. This moving mantle layer pushes the earth’s plates around.
Answer:
Because if the the environment cant support the population it will decrease until the resources are able to hold it again
Explanation:
It is made up of unicellular or multicellular beings, with aerobic or anaerobic respiration, autotrophs or heterotrophs, sexual or asexual reproduction.
I hope I've helped : )
Answer:
Reticular formation
Explanation:
An ancient structural component of the human brain stem, Reticular formations (RFs) comprise several groups of nuclei distributed throughout the brain. In reference to structure, RFs are a net-like arrangement of multi-polar neurons, in a densely interwoven group of fibers. These don't have clearly defined borders, and extend from the midbrain to make up the brainstem's core.
Brainstem RFs are connected to the cerebral cortex and hypothalamus- it mediates sensory functions such as touch, vision and hearing. As these also continue into the hypothalamus, they play a role in arousing the body into wakefulness or an alert state.
Answer:
Sickle cell hemoglobin occurs in the beta chain of hemoglobin due to point mutation in the sixth codon which changes from glutamic acid to valine which is hydrophobic that causes the change in the size of the RBC in a crescent shape.
The protein or amino acid chain of this condition is as follows:
Protein with Sickle Mutation: VAL HIS LEU THR PRO VAL GLU
which is translated from mRNA sequence
mRNA with Sickle Mutation: G U G C A C C U G A C U C C U G U G G A G
mRNA sequence is the complementary sequence or anticodons of the mRNA sequence RNA:
tRNA with Sickle Mutation: C A C G U G G A C U G A G G A C A C C U C
mRNA sequence is transcribed from the transcription strand of DNA sequence:
DNA with Sickle Mutation: C A C G T G G A C T G A G G A C A C C T C
