put the steps of the light reactions in the correct order.

1. atp uses energy to add a phosphate to adp forming atp

2. water is split to replace the electrons in photosystem ii

3. light energy is transferred to a chlorophyll reaction center where electrons become energized.

4. electrons from photosystem i become energized and escape photosystem i and move down the second electron transport chain.

5. at the end of the electron transport chain, the energized electrons and an h+ ion are used to reduce nadp+ to nadph

6. electrons move to an electron acceptor in the electron transport chain and electrons in photosystem ii are replaced by the splitting of a water molecule

7. electrons move down the electron transport chain, releasing energy

8. a protein in the electron transport chain, pumps h+ ions from the stroma into the thylakoid space

9. electrons from the electron transport chain close to photosystem ii replace the elctrons lost in photosystem i

10. photosystem ii receives photons in the form of light energy

11. h+ ions flow down the concentration gradient through a channel in atp synthase, releasing energy in the process

answer:

10,4,2,

explanation:

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
