A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
Answer:
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic
Explanation:
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
-this is a plant cell because of the cell wall
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
-prokaryotes don't have DNA contained in a nuclear membrane
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
- DNA contained in a nuclear membrane --> eukaryototic
- cell wall --> plant cells, which are eukaryotic
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

Which pair of properties apply to both mechanical and electromagnetic waves?
A.
Both waves carry energy and refract
B.
Both waves are longitudinal and refract
C.
Both waves are transverse and carry matter from one place to another
D.
Both waves carry energy and do not need a medium to travel through
Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.
What is a cell membrane made of?The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.
As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.
Thus, the correct option is A.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)
a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.
b) The two sides of a cell membrane face different environments and carry out different functions.
c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.
d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.
Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.
Hence , the correct option is B.
