Answer:
The correct answers are option 2, 4 and 6
Explanation:
2-The T tubules are the extensions of the cell membrane that goes deep into the center of the middle of the skeletal and cardiac muscles and are in close contact with the sarcoplasmic reticulum.
These tubes plays 2 vital functions in connecting an action potential to muscle contraction. T tubules causes the action potential from the plasma membrane into the interior of the muscle cell through voltage-gated Na+ and K+ channels.
An action potential causes the opening and closing of Calcium channels in the sarcoplasmic reticulum. The resulting change in cytosolic Ca2+ concentration triggers contraction of the myofibrils.
The T tubules play two important roles in linking an action potential to muscle contraction.
Answer:
A. multimodal and multiphasic
Explanation:
Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.
Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.
Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy, which typically involves the use of hypnosis in psychotherapy to treat medical conditions such as depression, eating disorders, anxiety, post-traumatic stress disorder (PTSD).
The treatment for post-traumatic stress disorder (PTSD) can be described as multimodal and multiphasic because it is characterized by series of activities and it takes place in various phases.

Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
