Answer:
Sun
Explanation:
The hydrological cycle is most like mainly propelled by solar energy. By evaporating water from the oceans, lakes, rivers, and even the surface, solar energy powers the cycle. Other water is lost from plants to the atmosphere resulting of the transpiration.
First of all - ecological interactions in the ecosystem indicates how species interact with each other and species interactions in the system include:
- competition,
- predation,
- camouflage
- mimicry
<span>In ecological competitions:</span>
- intraspecific competitions are an interaction where individual members of the same species compete for the same resources
- interspecific competitions are about which individual members of a different species compete for the same resources.

Answer:
The correct answer is - option C.
Explanation:
Iridotomy is a procedure which is used to treat condition like narrow angle glaucoma and chronic open angle glaucoma, angle closure glaucoma and other chronic glaucoma conditions. In many cases iridotomy is needed to be performed immediately.
Iridotomy procedure in this case is helpful as it is improve the outflow of the drainage which is causing the intraocular pressure which is 50 mm in this case and also will help in reducing the pain.
Thus, the correct answer is - option C.
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.
Can you type the question or take a better picture i can’t really see it
