Myelin is a lipid-made substance that surrounds the axons of some neurons. This myelin sheath acts as an electrical insulator and speeds up the propagation of the action potentials inside the neurons' axons.
Answer:
<em>Colon cancer</em>
Explanation:
Colon cancer can be described as a type of cancer which arises in the colon of a person. About 5 to 10% of colon cancer is known to be hereditary.
Lynch syndrome and Familial Adenomatous Polyposis (FAP) are two typws of colon which are known to be hereditary. The hereditary colon cancers are known to be caused by genetic mutations inherited from the mother or father of the person.
Answer:
<u>1. ATP - decrease
</u>
<u>2.NADPH - decrease
</u>
<u>3. sugars - decrease
</u>
And <u>True- Both ATP and NADPH are needed to make sugars.</u>
Explanation:
Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.
- H+, and oxygen, are formed from a water molecule as it's broken apart.
- From photosystem II, electrons are transferred to photosystem I.
- ATP is synthesized from ADP along with inorganic phosphate.
- To form NADPHH, H+ is added to NADP
If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.
In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of <u>CO2 with Ribulose 1,5-bisphosphate </u>(RuBP).
Answer:
the earth's interior is made up of of four layers. three solids and one liquid, (its not magma but molten metal) which is as hot as the sun's surface.
