B)landform 2 is what was made by the deposition of sediments
Answer:
3 The mRNA was not bound to by a ribosome 4 tRNA: anticodon matching 5 switching from normal nucleotide for an abnormal one .
Explanation:
3 If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.
4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.
5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.
Answer:
Enzymes catalyze all kinds of chemical reactions that are involved in growth, blood coagulation, healing, diseases, breathing, digestion, reproduction, and many other biological activities. On biological aspects, enzymes are instrumental substances to many functions in living organisms.
Answer:
Once the embryo sac has developed, pollination has occurred, and the pollen tube has grown into the ovary to make contact with the ovule, fertilization (fusion of egg and sperm) can occur.Typically, the pollen tube reaches the embryo sac via the micropyle (Greek, mikros + pyle = small opening), or opening, in the integuments of the ovule.. There, it discharges its sperm into the embry
Explanation:
The pollen tube enters into the ovule, through the micropyle. Inside the embryo sac, the tip of the pollen tube ruptures and the 2 male gametes are set free near the egg apparatus. Inside the embryo sac, one of the 2 male gametes fuses with the egg nucleus and forms a diploid zygote. This process is called syngamy or true fertilisation.
The given blank can be filled with cells.
The extracellular matrix is the protective tissues present as a coating of the cells. Both animals as well as the plant cells have the extracellular matrix, this coating provides support, biochemical protection and mechanical protection from the external environment of the cells. In the plant cells, the cell wall is a type of extracellular matrix.
