Answer:
1) abiotic synthesis of small organic molecules (monomers)
2) joining of monomers into polymers
3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry
4) origin of self-replicating molecules that eventually made inheritance possible
Explanation:
A should be labeled as being Bryophytes. I hope this helps anyone who needs to know this.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription
Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum makes an extensive internal system of membranes in the eukaryotic cells. It makes a system of tubes and sacs that run throughout the cytoplasm. The ER is connected to the nuclear envelop also and serves in the transport of substances and proteins throughout the cells with the help of transport vesicles. For instance, the proteins formed on the surface of rough ER are packed in vesicles that bud off from the surface of rough ER and are carried to the Golgi apparatus for processing.
