The cell membrane is a selectively permeable membrane which controls what goes in and out to ensure that not just anything comes in through it's own accord.
Answer:
From his observations of organisms in the Galapagos islands, Darwin reasoned that <u>organisms had adapted to new environments, giving rise to new species</u>
Explanation:
The Galapagos islands inspired Darwin to the discovery of the concept of evolution. He noticed that the species were similar from island to islan but still they had small , distinct differences, which helped them being best suited to thei environment, and conditions such as food sources, which varied from island to island. He also observed that organisms had adapted to new environments, giving rise to new species.
Hence,from his observations of organisms in the Galapagos islands, Darwin reasoned that <u>organisms had adapted to new environments, giving rise to new species</u>
The genes are the sentences.
Gene = a segment of DNA that codes for a particular trait
They usually live alone, when not breeding.
Answer:
The correct answer would be A) ribosomes.
A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.
They are the site of translation in both prokaryotic and eukaryotic cells.
They are made up two units which are called large sub-unit and small sub-unit.
In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.
In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
