<h2>Answer:</h2>
Sleep in which the brain becomes more active but muscle activity is blocked.
<h3>Explanation:</h3>
The brain cycles through five distinct phases during sleep: stages 1, 2, 3, 4, and rapid eye movement (REM) sleep. REM sleep makes up about 25% of your sleep cycle and first occurs about 70 to 90 minutes after you fall asleep. Because your sleep cycle repeats, you enter REM sleep several times during the night.
- During REM sleep, your brain and body are energized and dreaming occurs.
- REM is thought to be involved in the process of storing memories, learning, and balancing your mood.
- REM sleep begins in response to signals sent to and from different regions of the brain. Signals are sent to the brain's cerebral cortex, which is responsible for learning, thinking, and organizing information.
Answer:
Mitochodaria is present in majority of cells and plastid is present only in in few.
Explanation:
Endosymbiosis theory explain that mitochondria and plastids arose from bacteria through engulfing by larger cells because mitochondria and plastids contain different DNA than cell nuclei.
Mitochondria were acquired before than plastids because mitochondria is present in majority of eukaryotic cell and some cell have plastids with mitochondria.This explain that after the endosymbiosis of mitochondria some cells did endosymbiosis with photosynthetic bacteria to acquire plastid.
Answer:
The correct option is <u>C:</u> Posterior clinoid processes and dorsum sellae.
Explanation:
An Anteroposterior (AP) axial projection (Towne method) is a <em>radiograph of the skull</em> used to evaluate and demonstrate the <em>presence or state of fractures</em>.
Structures that can be seen are the entire <u>occipital bone</u>, the <u>petrous part of the pyramids</u>, and the <em>foramen magnum</em>. Through this last one, there can be seen the dorsum sellae and the posterior clinoid processes.
Answer:
a. identify boundary cases and test them
Explanation:
- The test is great as they serve as the implied contract abut the code should do and the testing enables us to asset the quality of the correctness of the algorithm and is to be correct with the respect to the specification hence its essential to identify the boundary and proves that the program gives a correct output.
A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems
