Answer:
The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.

Answer: The pathway involves the transcription and translation processes.
Explanation:
The DNA present in the somatic cells of the eukaryotic organisms undergoes transcription in which the DNA is used as a template to form mRNA. It occurs in nucleus
The mRNA encodes for a amino acid chain for a specific protein in the process of translation. It occurs in cytoplasm and require a cell organelle called ribosome.
The amino acid sequence for different proteins are different.
The answer is A. This is because, in a new environment, mostly of new bare rock can only support plants such as algae and moss (pioneer species). However, as they weather the rocks and soil begin to form, plants such as pteridophytes (ferns) begin to emerge. Eventually, when the soil is deep enough, higher plants such as shrubs and grass emerge and over time trees can grow.
