While norepinephrine is majorly a neurotransmitter (in synaptic transmission)
, it also acts as a hormone produced by
the adrenal gland. It is usually secreted as a stress hormone, just like
cortisol. It increases heart rate, blood flow
in skeletal muscles, production of glucose by the liver, especially in the
fight-or-flight response.
Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.
The biosphere includes all the living organisms on the planet
<u>Explanation:
</u>
- The biosphere includes all the living organisms on the planet
- The biosphere is a global ecological system that forms the layer of the earth where life exists.
- The layers of earth that form the biosphere are lithosphere (rock), hydrosphere (water) and atmosphere (air) which together known as an ecosystem.
- Biosphere acts as a self-supporting and self-regulating system were the remaining of the dead plants and animals are released into soil and ocean thus, in turn, it is reabsorbed by plants for growing.
- The biosphere sometimes is one large ecosystem that is comprised of a complex community of living and nonliving things functioning as a single unit.
6. A because carbs provide 50% energy and lipids 20% (rest from protein)
7. A e.g. Muscle cell for movement and blood cell for oxygen transport
