The correct answer is "transmission electron microscope".
The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.
Attached is a sample picture of a transmission electron microscope image of a mitochondria.
The single celled protists which is one of the example of
this is the paramecia survives and lives on extreme hypotonic environment. They
have the ability of having to contract their vacuoles in which this contributes
and help them to live and survive in a hypotonic environment.

College monitor roles include supervising and monitoring students within and outside the school building, enforcing appropriate student behavior, communicating with students regarding issues and/or behavior, escorting students and/or unauthorized visitors
Answer: 1. larva, 2. nymph
Explanation:
In complete metamorphosis the precursor of insect undergoes with four distinct stages to develop into complete adult insect. These are egg, larva, pupa and adult.
In incomplete metamorphosis the insect precursor hatches from an egg and then goes through several nymphal stages similar to adult.
Therefore, in complete metamorphosis the immature stage is called as larva and in the incomplete metamorphosis the immature stage is called as nymph.
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
