Answer: Anterior portion of the deltoid muscle.
Deltoid muscle is formed by three portions: Anterior or clavicular portion, middle and scapular part.
Contraction of each portion of the muscle leads to different movements
of the shoulder.The clavicular part causes the shoulder to flex, while the middle part causes abduction and
the scapular part causes extension.
Answer:
The correct answer will be- genes can be transferred among species
Explanation:
Green fluorescent protein or GFP is a protein which is naturally expressed in a jellyfish called <em>Aequorea victoria</em>. The protein absorbs the light and emits it in green color.
Scientist isolated the gene of the protein from the jellyfish in the 1960s and transferred it to the genes of the other species like bacteria or mice.
This shows that although the species can be isolated from the reproduction by reproductive barriers but the molecule containing code of life can be transferred easily without any barrier.
Thus, genes can be transferred among species is the correct answer.
RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.
Answer:
Explanation:
Leison is what is been seen in the brain as white Spot it is as a result of activities carried out in the brain. MR monitors how blood flows into a part of the brain will then transfer the lesion into the brain.
Myaline sheets surround the nerves cells forming a layer round the axons.
Break down of Myaline sheathe leads random shot of neurons this then result in white leison. The leison disappers after the myelin sheat have been healed or repaired by the actions of the neuron present.
Neurons then carries signals or impulse that the myelin sheat have been fixed.
Answer:
The correct answer is 2,0L.
Explanation:
We apply the formula for dilutions:
C1xV1 = C2xV2 --->V2= (C1xV1 )/C2
V2=(0,62Mx0,90L)/0,28M=<em>1, 99 L</em>
