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 gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
Answer: Systematics
Explanation:
Systematics is the study of diversity of organisms including past and present and relationships among living things. Systematics as analytical approach, help us to understand the diversity and relatedness of both existing and extinct organisms. Systematics is also important in carrying out the conservation issues because, it attempts to explain the biodiversity which is related to different kinds of species and could be used in preservation and protect the endangered animals and plants.
