Answer:
a. Two of these are correct.
Explanation:
The two correct options are
b. Is a critical component or requirement for wound healing to take place
d. Existing blood vessels give rise or sprout to form new blood vessels
Angiogenesis is the physiological means in which new blood vessels form pre-existing vessels, developed in the starting phases of vasculogenesis. Angiogenesis is a usual and important process in growth and development, wound healing and in the development of granulation tissue.
The growth and maturation of blood vessels is a largely regulated multistep mechanism called angiogenesis.
The Answer is B) Bilateral Symmetry
Answer:
transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene
Explanation:
The transcription process in eukaryotes happens in 3 stages:
- Initiation
- Elongation
- Termination
The initiation of transcription starts when a set of proteins called the transcription binds to the promoter region of a gene on the coding strand of DNA. Thereafter, the RNA polymerase enzyme binds to the promoter region thereby opening up the double helix structure of the DNA in anticipation of transcription.
During elongation, RNA nucleotides are added to the growing RNA strand in 5' to 3' direction with the DNA unwinding and winding back as the polymerase moves along the coding strand in 3' to 5' direction.
Transcription terminates when the RNA polymerase gets to the end of the gene being transcribed signalled by a sequence of DNA known as the terminator.
<em>Hence, in the illustration, the correct answer would be that the transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene.</em>
Yeah.... Its A,
But why ask when u know the answer tho?
<span>Atherosclerotic
peripheral vascular disease is symptomatic with at least 50% occlusion. The primary peripheral symptom, due to ischemia, is calf pain.
</span>This disease is a form of arterial insufficiency, which means that blood circulation through the arteries is decreased.<span>Other symptoms include painful cramping in the hip, thigh or calf muscles after certain activities, such as walking or climbing stairs (claudication)<span> and leg numbness or weakness.</span></span>
