Answer:
C) 6
Explanation:
The balanced equation for aerobic cellular respiration is:
C₆H₁₂O₆ + 6 O₂ ----> 6 CO₂ + 6 H₂O + Energy (ATP)
For each glucose molecule that's oxidized, 6 oxygen molecules are used in order to produce ATP. Carbon dioxide and water are byproducts of aerobic respiration..
Answer:
When the pollen tube grows into the ovule
Explanation:
Simmilar to animals, fertilization occurs when the egg (ovule) and the sperm join together to produce a new individual. In flowers, when the pollen tube grows into the ovlue is when pollen and ovule join together and fertilization occurs. A new seed is the produced, ready to produce a new individual.
<h2>Epigenetic modification </h2>
Explanation:
A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA
