Quaternary consumers eat the tertiary consumers and are carnivores. These consumers are typically carnivorous animals. In my opinion, all ecosystems necessarily should have a quaternary consumers. This is because they complete the food chain. In every, ecosystem you can see these consumers.
The prenatal circulation of blood is different than the postnatal circulation, mainly because the lungs are not in use. The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord. Blood from the placenta is carried to the fetus by the umbilical vein.
<u><em>true </em></u>18. ATP is a source of usable energy for the cells.
the bond between the 2nd and 3rd phosphate group is broken to release energy
<u><em>true </em></u>19. ATP is made during photosynthesis.
in the light dependent reactions of the photosynthesis the hydrogen protons pumped in during the electron transport chain are used to synthesize ATP
<u><em>true</em></u>20. ATP is made during respiration.
during anaerobic resipiration and aerobic respiration ATP is produced
<u><em>false</em></u>21. ATP is a waste product of respiration and photosynthesis.
ATP is not a waste product, it plays an important role in photosyntheis, the main role of respiration is ATP production
<u><em>true</em></u> 22. Photosynthesis and respiration form a cycle.
since the reaction of photosynthesis is
6CO2+6H2O-->C6H12O6+6O2
and the reaction of respiration is
C6H12O6+6O2-->6CO2+6H20
you can see that the producs of photosynthesis are used in aerobic respiration and the products of aerobic respiration are used in photosynthesis so the two form a cycle
Answer: nucleotide triphosphates that lack a hydroxyl
Explanation:
Answer:
The correct answer is: DNA.
Explanation:
- DNA or Deoxyribonucleic acid is the genetic material that is transmitted from the parents to the offspring.
- It encodes for genes that gives rise to one of the most important structural and functional unit of cells, that is, the Proteins.
- The DNA is composed of a double helical backbone, made up of alternate deoxyribose sugar and phosphate groups linked by phosphodiester bonds. Each sugar molecule is linked to a nitrogenous base, purine or pyrimidines.
- The purines are Adenine(A) and Guanine(G) and the pyrimidines are Thymine(T) and Cytosine(C).
- Adenine of one strand of the helix forms two hydrogen bonds with the Thymine on the other strand and the Guanine of one strand of the helix forms three hydrogen bonds with Cytosine on the other strand.
- In some organisms, RNA or Ribonucleic Acid functions as the genetic material.
