Answer:
The answer is Angiosperms and gymnosperms
Answer:
The biological level of organization represented by all of the three steps of gene expression products is <em>the central dogma of molecular biology.</em>
Explanation:
DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.
The functional products of most known genes are polypeptides. Genes that specify polypeptides are called protein-coding genes.
Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.
The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
I think the correct answer would be D. In the process of petrification, a tree burning is not included. Petrification is a process that involves organic materials turning into fossils by replacing the original contents of a certain object with minerals.
Apical surface is the name of the epithelial cell surface that faces the outside of an organ.
The edge of the epithelium that faces light or the outside environment is called the apical surface.
The apical surface of the epithelial cells, where the lumen of the vesicles and tubules are located, and the inner surface of the body cavities, form the interface between the extracellular and underlying tissues.
It has multiple functions, including absorption and excretion, immune surveillance, sensory conduction, and barrier formation.
These functions are activated by several specializations, including glycocalyx (it cushions and hydrates the apical membrane), apical plasma membrane lipids(it restricts flow of water and solutes), channels and receptors (it regulates active and passive transport and sense the presence of growth factors), cytokines, and mechanical stimuli (eg, tensile and shear stress).

Answer:
Plasma membrane contains 2 layers
Explanation:
Plasma membrane is extremely pliable structure composed of two layers of phospholids. Cholesterol are also found in between the phospholipids.
