Answer:
Cataplexy is condition in which sudden loss of muscle tone occur.
Explanation:
Cataplexy is sudden and uncontrollable muscles weakness or paralysis that comes on during the day and is often triggered by a strong emotion such as excitement or laughter. Cataplexy occur during working hours. A more severe episode may involve total body collapse. In cataplexy the voluntary muscle tone occur. This condition is mostly associated with narcolepsy which is a sleep disorder.. Symptoms of cataplexy have;
1) Dropping eyelid.
2) Jaw dropping.
3) Neck muscle weakness.
D. Complementary strands of mRNA
In transcription, RNA is made from RNA.
Answer:
Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. The method used to transfer heat is usually the one that is the most efficient.
Answer:
1600cm³
Explanation:
The volume of a cuboid can be calculated as follows;
V = L × B × H
Where;
L = length (cm)
B = breadth or width (cm)
H = height (cm)
However, in this question, the area of the book is said to be 400cm². Since area of a rectangle or rectangular-shaped object like the book is L × B, this means that the length and breadth has been combined in the area. Hence;
Volume of the book = area of the book (L × B) × Height of the book (H)
Volume = 400cm² × 4cm
Volume = 1600cm³
Therefore, the volume of the book is 1600cm³.
Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists. For example, one may never see a person with blue eyes and brown hair if the alleles for the two traits, hair and eye color, were inherited together. However, it is worth noting that there is "genetic linkage", meaning full or partial violation of independent assortment among certain trait groups.
There are 46 chromosome in a normal human diploid cell, 23 inherited from the mother's egg and 23 inherited from the father's sperm.
