New capillaries that stem from intact capillaries are delicate and take time to become as stable as the preexisting capillaries.
<h3>
What causes bleeding?</h3>
When skin is cut with a sharp object, it begin to bleed. This is because blood vessels in that area are damaged. Bleeding serves a useful purpose because it helps to clean out a wound but too much bleeding can cause adverse effect on your body so we can conclude that New capillaries that stem from intact capillaries are delicate and take time to become as stable as the preexisting capillaries.

Forming of 2 daughter cells from a cell is considered asexual. An example would be bacterial fission. Or mitosis in our cells which is asexual. A single cell duplicates its genetic material(dna) so for example it becomes 4n and splits into two identical daughter cells(each is 2n).
Hope this helps:)
Answer:
(b) Volcanic eruptions
Explanation:
Volcanic eruption is naturally occurring event. In Volcanic eruptions many toxic gases are released into the atmosphere such as carbondioxide, carbonmonoxide, hydrogen sulfide, hydrochloric acid and Sulphur dioxide etc. These toxic gases goes to the atmosphere and combine with water vapours forming the water acidic. When this acidic water comes to the earth surface, skin and valuable stones are damaged from it.
The question is incomplete. The complete question is as follows;
Examine and characterize the two motor pathways in the stretch patellar reflex.
A) Alpha motor neurons send efferent messages to the quadriceps, while parallel efferent messages to the hamstrings are reduced.
B) Alpha motor neurons send efferent messages to excite the quadriceps and the hamstrings are reduced.
C) Alpha motor neurons activate the quadriceps. Once the quadriceps have contracted, alpha motor neurons inhibit the hamstrings.
D) Interneurons excite alpha motor neurons, which in turn excite the muscle.
Answer:
Alpha motor neurons send efferent messages to the quadriceps, while parallel efferent messages to the hamstrings are reduced.
Explanation:
Neuron is the structural and functional unit of the nervous system. The neurons can be classified as sensory neuron, motor neuron and interneuron based on their function.
The knee reflex is known as patellar reflex that involves in the movement of knees and stretching of patellar tendon. The efferent message is send by alpha motor neuron that are located in the anterior horn of the spinal cord. This send to quadriceps that results in the muscle contraction. In this process, the hamstrings messages are reduced that plays an important role in patellar reflex.
Thus, the correct answer is option (A).
I’m pretty sure it’s B because they need to be able to replace other cells when they die off but its also to maintain a healthy size so if they are growing too much they may need to split
