embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively.
b) metaphase)
c)anaphase
d) telophase
I need help!
Prophase: Replication of chromosomes and chromosome become visible x shapes.
Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.
Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.
Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.

A Insulation
B. Structural support
C. Provide energy
D. Control metabolic functions
Lipids accomplish many different functions, such as energy provision, structure, and insulation, among others. However, they are not in control of metabolic functions. Therefore the answer is D.
--------------------------------------------
Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails.
Lipids are involved in several functions. Among others, we can mention,
In the organism, lipids constitute the energetic reserve of late or differed use. These are in the triacylglycerol form. Their caloric content is very high and represents a significant source of energystorage.
Aerobic combustion of lipids produces a great metabolic water quantity. Some desertic animals -camels- store fat in their tissues to produce water when needed.
Some other animals produce a specialized adipous tissue called brown fat. Lipidic combustion in these tissues is decoupled from oxidative phosphorylation. Most of the energy derived from combustion is used for heat production.
Hybernating animals use this brown fat to produce energy during the long hibernation periods.
Two lipidic bilayers compose the cell membrane. They are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. They can also provide protection and isolation for specialized tissues and organs.
Lipids are involved in cell signals. They control the fluidity of membranes in the central and peripheral nervous systems, playing a role in electrical signals transmission and synapses.
