Answer:
Moth Orchid
Explanation:
The Moth Orchid is the most common type of orchid and bears the name because of its supposed resemblance to a moth in flight. Native to Southeast Asia, the Philippines, and northern Australia, the Moth Orchid isn't exactly hard to find, and it comes in nearly every colour of the rainbow.
Answer:
A,B and E
Explanation:
- I+: I refers to the lac repressor, the + indicates that the repressor is functional
- P+: P refers to the promoter region and the + indicates that the promoter is functional
- Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
- Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
- Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional
So based on the breakdown above:
- C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.
- D is not true because Z-, no β-galactosidase is produced.
Only A, B and E apply.
Answer:
Cellulose gives strength to cell.
Explanation:
Cellulose is a type of polysaccharide which is present in the cell wall of plant. It provides strength to the cell. It also helps in the absorption of water molecules from the surrounding environment.
Cellulose is composed of 44.44% of carbon atom, 6.17% hydrogen atom, and 49.39% oxygen atom. The chemical formula of cellulose is (C6H10O5)n.
Yes it does put carbon dioxide in the atmosphere
