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 would be A. The DNA is the molecule that has the instructions needed for an organism to develop.
Hope this helps!! (:
The correct answer is option C. A leaf growing in full sunlight
The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
It's about the size of our sun and called a Main sequence star
Answer:
The plant cell becomes turgid
Explanation; freshwater contains a low amount of salt concentration .when cells are placed in it,it creates an osmotic difference, as the cytoplasm of the cell would be of higher concentration than the surrounding water .as a result,water moves into the cell by osmosis.
Most Unicellular organisms has organelles such as contractile vacuole to expel excess water out of it's cell.if the animal cell is unable to expel water,it bursts.
In plants cells,the cell swells and the swelling is checked by the inflexible and rigid cell wall.
The cell wall of plants are made of cellulose, lignin and pectin.
