Answer:

leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines

<span>For instance, during the concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences. </span>
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span>

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released  as  ELECTRONS  move through the first electron transfer chain. This energy pumps HYDROGEN IONS  into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

  1. Luminous energy is trapped by chlorophyll in Photosystem II.
  2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
  3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
  4. <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
  5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
  6. <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
  7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
  8. The released energy is used to produce ATP molecules.
  9. Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.

A pregnant woman will probably not be able to deliver her baby vaginally if the ____________ is not large enough to accommodate
valina [46]

The answer is pelvic outlet. It is because if this is not large enough and it is small, the baby won’t be able to be carried or delivered out from the woman’s vagina as it won’t fit the baby and will likely lead to complications if pushed through.
