The correct answer is D. Caulerpa
Explanation:
Protists are a type of unicellular organisms that are eukaryotic which means they contain a defined nucleus but that are not plants, animals or fungus. Considering protists only contain one cell in most of the cases they are small or restricted in size this includes Dictyostelium which are microscopic organisms that consume bacteria and plasmodium. However, in the case of Caulerpa, these are not limited to size as Caulerpa is a type of alga that has macroscopic cells and indeed in some cases can be around 3 meters long. On the other hand, Ulva is also an alga but is considered in the plants' domain and therefore is not a protist. Therefore the one that contradicts contradict the statement that unicellularity restricts cell size in protists is the Caulerpa.
Answer:
C. Individuals with thicker fur had a survival advantage in the cold, allowing these individuals to reproduce moe often and create more offspring.
Explanation:
Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?
Natural selection takes place due to 3 underlying reasons:
Reproduction
Heredity
Variation in fitness of organisms.
Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.
Thus, option C is correct.
Since, the experiment is not given but on the basis of the mechanism of genetic transfer this question can be answered.
Answer:
The mechanism of gene transfer is important and beneficial for bacteria in the adverse environment conditions. The different mechanism of gene transfer are conjugation, transformation and transduction.
The ampicillin resistance gene is present on the plasmid DNA and not on the chromosomal DNA. Only conjugation is the mechanism in which the plasmid DNA is transferred from one bacteria to another bacteria. The ampicillin resistance gene is transferred from Strain II to strain I means from the bacteria that has the ampicillin resistance gene to the bacteria that has no ampicillin resistance gene in it.
Explanation:
It's True
Who were the first scientists responsible for organizing and identifying living things?
=> Swedish naturalist and explorer Carolus Linnaeus was the first to frame principles for defining natural genera and species of organisms and to create a uniform system for naming them, known as binomial nomenclature.
