Answer:
B. differential
Explanation:
The culture medium is a chemical preparation that has the necessary nutrients for microorganisms of a given biological sample to multiply, allowing its study, identification and analysis. The main components of a culture medium are sources of carbon, energy (sugars), nitrogen, phosphorus and minerals.
There are several types of culture medium, among them we can mention the differential culture medium, which is the type of medium that is being used in the experiment shown in the question above. The differential culture medium allows the distinction between various genera and species of similar microorganisms. This distinction is possible because this type of culture medium has substances that allow for a presumptive differentiation, evidenced by the color change or the morphology of the colonies.
Anatomical and molecular features often fit a similar pattern due to Homology. Homology is the existence of shared ancestry between two structures or genes in a different species.
A process that can cause this not to be the case is Convergent Evolution.
Convergent Evolution occurs when two unrelated species independently evolve similar traits to cope with evolutionary changes.
Answer:
Fast Facts: Lipids
- A lipid is any biological molecule that is soluble in nonpolar solvents.
- Lipids include fats, waxes, fat-soluble vitamins, sterols, and glycerides.
- Biological functions of lipids include energy storage, cell membrane structural components, and signaling
There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents.
False
Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size.
Both cell types: use ribosomes to synthesize proteins, contain DNA.
Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.
In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.
The advantage of asexual reproduction (binary fission) in paramecium is a large number of offspring that are reproduced very fast. Large number colonies which are formed that way may survive and compete with other organisms. Another advantage is that this type of reproduction doesn’t acquire energy for finding a mate.
<span>The advantage of sexual reproduction is that offspring reproduced sexually are different (asexually have genetically identical offspring).</span>
