Hypoxia is the state which oxygen is not available in sufficient quantities at a tissue level in the body to maintain the homeostasis. The graph shows the concentration of this condition in Long Island Spund from 91 through 09 in mg/L, showinng in the data that the west area of the region has more cases os hypoxia than the east. Therefore, between the options the one that is a true statement about how well oxygenated to support marine life the region was during that period is the letter C. most years, the water near New York has inadequate oxygen to support marne life.
Auxin is used to stimulate plant growth which occurs at the roots and shoots of plants. you must have heard that plant growth is apical therefore it helps for apical dominance. <span>Apical dominance is the phenomenon whereby the main, central stem of the plant is dominant over (i.e., grows more strongly than) other side stems; on a branch the main stem of the branch is further dominant over its own side branchlets that is the shoot has more control over the lateral bud growth.</span>
Answer A:
1. Spiral chloroplast:
This organelle help in photosynthesis, because it contain green pigment called chlorophyll in which water and carbon dioxide combine in the presences of sun light to prepare glucose.
2. Cell wall:
It is chemically composed of<span> an outer layer of pectin and an inner layer of cellulose. It provide rigidity and shape to spirogyra cell.</span>
Answer B:
The other parts which are not labelled include mucilage, cytoplasm, pyrenoids, cytoplasmic strand.
Answer C:
Function of pyrenoid:
<span>Each chloroplast strand has several round bodies called 'pyrenoids', which are responsible for starch production.
</span>Function of mucilage:
Mucilage help in retaining water in cell.
Answer:
cause the chromosomes are divided in meiosis-1 in pachytene phase
Explanation:
Cohesion occurs when molecules of the same substance are attracted to each other.
Hope this helps!
