flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells
nucleus, mitochondrion: Both of these are found in Animal cells X
ribosome, cell wall: Cell wall is only in plants X
chromatin, chloroplast: Chloroplast is only found in plant cells X
Explanation:
Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.
Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.
However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)
Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)
I would choose the 1st option as the best answer here because it is more detailed.

What change to the following molecule's structure would result in a saturated fat?
Answer:
It needs to gain a Hydrogen atom to eliminate the double bond between the two carbons.
Explanation:
Unsaturated fat has one or more double bonds in its molecule. Saturated fat has a single bond. If you want an unsaturated fat to become saturated it needs to gain more more hydrogen atoms which will eliminate the double bonds between carbons of the unsaturated fat.

Microfilaments are a component of a cell's cytoskeleton and are made of the protein actin. They are important for giving a cell its shape and also aid in _______.
A.) Protein synthesis
B.) Cellular movement
C.) DNA replication
D.) Energy conversion
Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.
What are Microfilaments?Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.
Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.
Therefore, the correct option is B.

Maribel brings her backpack to the lab. She is also given a set of lab materials. What is the safest way for Maribel to organize these items in a lab?
Answer:
The personal items should be off the table, and the lab materials should be placed neatly away from the edge of the table.
Explanation:
It is given that Maribel goes to the lab with her backpack and she is given the lab materials to be used inside the lab to perform her experiment.
Now Maribel in the lab before doing her experiment must keep the personal items like her backpack off the working table and the lab materials are should be kept away from the edge of the table otherwise it might fall accidentally and hurt her.
One needs to be very careful while in the laboratory. One should follow the safety procedures to remain safe and also ensure safety of others. Being unsafe and disorganize can hurt others and can cause harm to others. There are various equipment and chemical in the lab. Therefore one should be careful while working in the lab.

Identify some changes in genetic traits that have occurred over several generations in an agriculture crop.
(ignore my name)
Answer:
Environment: All external conditions and factors, living and nonliving (chemical and energy), that affect an organism or other specified system during its lifetime.Generation: our step in the line of descent of a family / all the people born and living about the same time.Phenotype: An organism's physical appearance, or visible traits.Genotype: An organism's genetic makeup, or allele combinations.The kind of changes with respect to the genetic traits that have occurred over several generations in an agriculture crop should be environment, generation, etc.
Changes in the genetic traits:Environment deals with the external conditions and factors, that should be lived or non-lived also it impact an organism at the life time period.
While on the other hand, the generation should be the step with respect to the line of the family descent
Therefore, in this way, the changes should be considered.

When the concentration of molecules are the SAME on both sides of the cell
membrane, the solution is *
A. Hypertonic
B. In equilibrium
C. Hypotonic
D. Kinetic
Answer:
isotonic: in equilibrium.
Explanation:
tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. if let's say sodium is the same both inside the cell membrane and outside the cell membrane then it is isotonic in equilibrium.
Once assembled, what is the key to a protein's unique function?
Answer:
Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function
The endoplasmic reticulum is an important region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.
What is importance of protein folding?Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.
Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.
These elements affect a protein's capacity to fold into the appropriate functional forms.
Therefore, Protein folding give unique properties to protein functions.

Jimmy explained on his biology test that organisms grow because their cells grow. Explain why his answer is either right or wrong and if he is
wrong explain how organisms actually grow.
Answer:
See the answer below
Explanation:
Jimmy was right to say organisms grow because their cells grow.
The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells.
A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.
