Answer:
As light intensity increases to 800 (units), the rate of photosynthesis also increases. This is because a higher light intensity results in an increased rate of the light dependent reaction. However, when light intensity increases above 800, the rate of photosynthesis remains constant. This is because the light intensity is no longer the limiting factor, meaning that something else must be limiting the rate of photosynthesis. This could be carbon dioxide concentration or water availability. CO2 is required for the light independent stage of photosynthesis (the Calvin cycle) whereas water is required to produce H+ and e- for the electron transport chain.
Explanation:
I hope this would be enough to get the 4 marks. The main point is that the rate does not increase each time light intensity increases, because there is a limiting factor that is affecting the rate of the light independent reaction.
Answer:
- Soil knife to make digging the soil easier
- Handheld pruners to fix and prune the plants of your garden
- Gloves to keep your hands save from any harmful or chemical substance.
- Binder twine to maintain the plants (to tie their stems together)
- A notepad and pen to check the progress of your plants (e.g.: you might need to note down whether a plant may need more water or nutrients (mineral ions), if you see a plant almost wilting, appropriate actions must be taken so notepad and pen can help you track this down, so that you can get the appropriate resources needed)

Answer:
Blood-brain barrier.
Explanation:
Blood brain barrier may be defined as the barrier between the blood capillaries and the component of the brain tissue. This blood brain barrier provide protection against the pathogens present in the blood.
The blood-brain barrier uses tight junctions that prevent the entry of microbes in the underlying tissue. The tight junctions allows only the entry of some selected particles and prevent the entry of other particles.
Thus, the correct option is (3).
Evaporation of water is equal to precipitation of water. I hope this helped :)
