According to endosymbiotic theory, the chloroplast evolved as a result of engulfment and assimilation of a Cyanobacteria by an eukaryotic cell.

Explanation:

Endosymbiotic theory supports the view that ceratain organelles of the eukaryotic cell evolved as a result of engulfment of single celled organism.
Evidences that support this theory is the presence of organellar DNA.
It is assumed that Mitochondria evolved as a result of engulfment and assimilation of an aerobic prokaryote while Chloroplast evolved due to engulfment and assimilation of a photosythetic prokaryote by an Eukaryote.
After the engulfment ,these organisms however escaped the phagocytosis and began to benefit the eukaryotic Host.
Soon it lost many of its Genes to the eukaryotic nucleus and became dependent on the Host.
Thus a symbiotic association was established between the prokaryote and the host.Giving rise to cell organelles.

what is the texture and appearance of the potato strips after being immersed in various concentration of sucrose solution

Alexxx [7]

This process is a technique of osmosis. Osmosis is the movement of solvent particles. For example, water along its concentration gradient, from high to low concentration, via a semi-permeable membrane is changing the structure of the molecules in the potato strips.

Since the environment of the potato strips are in a sugar concentrate, the potato will lose its water content and so loses weight and the strips will be thinner and dryer.

Explanation:

Small patches of protect land makes it difficult for animals to move around and see resources in other areas.

Protected areas or conservation areas are locations that receive special protection because of the natural diversity found in them.

Protected areas in some places are the last refuge for animals and plant species for safety.
The larger a protected area is, the better and more advanced an organisms niche can be.
A small protected area limits the niches of roaming animals and makes it difficult to seek for resources out of their limited scope.
