Answer:
Missense
Explanation:
The key in this question is 'which type of mutation causes this problem.
The description of this disease gives the the answer. A replacement of a glutamic acid amino acid with and Valine amino acid is called missense.
Silent mutation do not cause any difference in structure or function of the protein.
Insertions are an additional nucleotide or 2 added to the sequence
Frameshifts are the same as insertions, but the insertion occurs in part of the gene that codes for the protein. Because of that 'insertion' the reading frame of this gene is out and the protein sequence is not correct.
Answer:
D) shivering.
Explanation:
Because the outdoor temperature is high and days are hot, a dog would not be shivering unless it were to be cold.
Answer:
Epimysium
Explanation:
The muscle fibers of a skeletal muscle are surrounded by three layers of connective tissues to form a muscle. The three layers of connective tissues are –
a) Endomysium – It is the inner most layer of connective tissue that surrounds all the muscle fiber
b) Perimysium – This layer lies above the endomysium and forms a fascicle
c) Epimysium – This is the outermost layer of the connective tissue surrounding the skeletal muscle. Epimysium form a complete muscle by encircling the fascicle
Answer:
Whether the animal has a vertebral column or not.
Answer:
C)The luminal side of the thylakoid membrane has a higher pH than the stromal side.
Explanation:
During the photophosphorylation, the electrons move through many electron carriers which allow the transport of hydrogen ions in the luminal side against the concentration gradient. This allows the increase in the Hydrogen ion concentration to the luminal side of thylakoid membrane and reduction in the hydrogen ion concentration of the stromal side.
Therefore due to the increased concentration of H⁺ ions in lumen during the photophosphorylation, the lumen has a lower pH than the stroma. During photophosphorylation, the pH of lumen decreases up to 4 and the pH of stroma increases up to 8. So the false option is C.
