Answer:
The correct answer is - due to the law of segregation.
Explanation:
In the given case the genotype of Rr and as we know R is a dominant characteristic for round seeds and r represents the recessive allele for wrinkled seeds in a pea plant. So if a plant has Rr in its genotype it means it is a phenotypically round pea plant due to dominance in this heterozygous case.
The law of segregation states that two alleles of a gene of a specific trait will be distributed randomly and there is an equal chance of each allele to end up in the gametes, similarly in this case both alleles can be segregated to gametes and it is a random process.
Answer: C
Explanation: I took the test hoped this helped :)
The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:
• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units.
• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures.
• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures.
• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.
• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.
Answer:
A. much of the variation in individuals of a population is heritable
Explanation:
Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.
Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
