Answer:
Blastocyst
Explanation:
In early pregnancy, the blastocyst stage continues for about 5 days before the embryo implants in the uterus, or womb.
At this stage, stem cells begin to differentiate.
With the right stimulation, the cells can become blood cells, skin cells, and all the other cell types that a body needs.
Answer:
The correct answer will be options
1. Lateral corticospinal tract
2. lower motor neuron
3. Ventral horn.
Explanation:
The descending neuron originates from the cerebral cortex of the brain which converges and descends into internal capsule through which it descends into the brain stem of the brain.
At the crossline of the brain stem and spinal cord upper motor neurons descend into the spinal cord through which it passes into the lateral corticospinal tract and reaches the ventral horn. At these ventral horns the upper motor neurons transfer its impulse to lower motor neurons which sends signals to effector organs.
Thus, Lateral corticospinal tract, lower motor neuron and ventral horn are the correct options.
During external chest compression on children under 8 years old the sternum should be compressed about 1/3 to 1/2 the depth of the chest.
<h3>What is the correct chest compression for a child?</h3>
Cardiopulmonary resuscitation is known as CPR. When a child's respiration or heartbeat stops, it is a life-saving surgery.
Compress the breastbone. For a baby or infant, press down 4 or 5 cm, or around one-third of the chest's diameter. At a rate of around 100–120 compressions per minute, quickly release the pressure before repeating. When we've completed 30 compressions, tilt the head, elevate the chin, and take two deep breaths. For adults, compress the chest to a depth of at least 2 inches. Allow the chest to fully rise each time. These compressions must be swift, forceful, and uninterrupted.
