Answer:
The mitochondria are called the powerhouses of the cell, where ATP is produced. It is composed of an inner membrane called cristae, and an outer membrane that covers the organelle.
The cell wall is a rigid structure made from(in the case of plant cells rather than bacteria or fungi) cellulose and other rigid fibers.
The cell membrane is a fluid, thinner structure made up of a double layer of phospholipids which are comprised of the hydrophilic heads facing outwards and hydrophobic tails facing toward each other in the layer.
The nucleus has protons, and neutrons that are contained within it, and electrons around it.

Answer:
B. 50 mM glucose; E. 300 mM glucose
Explanation:
In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.
The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.
The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
Answer:
a. Lochotrophozora
Explanation:
Molecular research and studies complement morphological research and improve our awareness and knowledge of evolutionary history. Previously, morphological studies could only reveal to us the variations and distinctions, but molecular studies and phylogeny have enabled us to pinpoint the fundamental mechanism of this variation on a genetic level, as well as locate it down to evolutionary lineage, which has led to more enhanced genealogy and evolutionary studies.
However, the group of organisms that best reflects and represents this kind of change is: Lochotrophozora
