There is one choice missing from this question:
<span>a. narcoleptic fits
b. nightmares
c. apnea episodes
d. night terrors*
The correct answer is "night terrors". Night terrors are intense feelings at the first half of non-REM sleep that is characterized by fear, horror, trembling, shaking. Night terrors are different from nightmares as there are physical effects carried out from night terrors upon waking up such as screaming, crying, and sudden movements.</span>
Answer:
Nuclear decay rates are constant
Explanation:
Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.
Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.
The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).
Answer:
Explanation:
I have been raised under an autthoritative parenting style, and my parents were both raised under an authoritarian style (it was more evident in my mother, because my father's mum died when he was 13). I think it was authoritative because they didn't let me do whatever I wanted, but they also didn't keep so much control on me, so I had certain level of freedom, as long as I didn't break anything xD
Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

Answer:
Asexual reproduction can be described as a process in which daughter cells are produced which are 100% identical to the parent cells. Unlike the process of sexual reproduction, no recombination occurs in asexual reproduction. Hence, no variability is produced when organisms reproduce by this method.
<u><em>As there will be lack of variability in asexual reproduction, the whole of the particular species might become endangered or extinct due to a disease or due to other factors like pests.</em></u>
