<u>Answer</u>:
Femur diaphysis and epiphyseal ends is made up with cortical bone and contains bone narrow. It is in the middle tabular part and composed with compact bone and central marrow cavity is situated around it. It is round in shape and a long bone. It is the origin of the attachment of many muscles as well as ligament.
The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.
Answer:
As a transcription factor
Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.
The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.
Thus, as a transcription factor is correct.
Answer:
mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.
Explanation:
Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the r<em>ough endoplasmic reticulum</em> or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.
The <u>rough endoplasmic reticulum</u> is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins <u>starts in the cytoplasm</u> with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.
Membrane proteins are synthesized in the endoplasmic reticulum and <em>sent to the Golgi complex in vesicles</em>, where it happens the final association of carbohydrates with proteins. Finally, protein is transported <em>from the Golgi complex to its final destiny, the membrane. </em>
Answer:
Alzheimer's disease
Explanation:
Neurodegenerative disease is the condition which is caused when the fundamental unit of the nervous system called neurons degenerate. The two main neurodegenerative diseases are Alzheimer's disease and Parkinson's disease.
The Parkinson's disease is the disease which affects the musculoskeletal system but the Alzheimer's patient is not able to recall the memory and events, therefore, interfere with the deterioration of the cognitive and emotional abilities.
Thus, Alzheimer's is the correct answer.
