Cellular respiration happens in all eukaryotic cells and it occurs in the mitochondria, the powerhouse of the cell. cell resp breaks up glucose in order to create more ATP for the cell. the products that go IN are GLUCOSE and OXYGEN. the products that come OUT are CARBON DIOXIDE, WATER, and of course, ENERGY.
Some reflexes are theorized to exist because they have the survival
value. Sigmund Freud First to theorize that we pass through different stages, behaviour
is governed by the reflexes that we are born with, start to develop schemata,
but need to develop permanence.
Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in this world. Diseases have always been present during the evolution, acting themselves as a natural selectors - the weaker organisms get sick and die. Not just humans, but all species have to establish a great protecting mechanism in order to survive. That is how our bodies are built, to be able to withstand and survive in the conditions we live in, and that is why our immune system has to be taken care of.
The two are blood and lymph
Photosynthesis in plants occurs in two stages. These stages are known as the light-dependent reactions and the Calvin Cycle.
The first stage of photosynthesis is the light dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).
<span>The second stage of photosynthesis is the Calvin Cycle. These reactions occur in the stroma of the chloroplast. Energy from ATP and electrons from NADPH are used to convert carbon dioxide into glucose and other products.</span>
