According to Mendel’s law of dominance, which statement best describes the result of a cross between parents with genotypes Rr and Rr?

Answers

Answer 1

Answer:

Answer:

C: All offspring with at least one R will have red flowers.

Explanation:

Mendel's Law of Dominance states that: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”

This simply means that if there exists two contrasting traits (I.e Rr), one of the traits will always suppress the other, thereby expressing itself. R suppresses r, thus making the offspring with big R have red flowers. The trait is called a dominating trait and the suppressed is called recessive trait.

Every year _______ species go extinct.
a. 3
b. 72
c. 1000
d. 20000

Answers

Every year 20,000 species go extinct. Thus, the correct option for this question is D.

What is Species?

Species may be defined as a cluster of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. It involves identical organisms that interbreed with one another in order to exchange genes. It is responsible for creating fertile organisms.

Species extinction is the ecological force that derives the mechanism of elimination of species from their native environment. This stimulates due to varieties of external influences like lack of food, space, mating selection, involvement of human activities, the action of predators, etc.

So, due to these external influences, it is found in research that approximately 20,000 species go extinct every year.

Therefore, every year 20,000 species go extinct. Thus, the correct option for this question is D.

The stress force that causes a mass of rock to pull or twist in opposite directions in called ______

Answers

The force produced when rocks pull in opposite directions is called shearing. Convection currents in the mantle cause tectonic plates to move.Sometimes they slide past each other in opposite directions. This region is called a strike slip fault or transform plate boundary.

Shearing in continuum alludes to the event of a shear strain, which is a distortion of a material substance in which parallel inner surfaces slide past each other. It is instigated by a shear worry in the material. It happens when the material is yielding. The way toward shearing a material may actuate a volumetric strain alongside the shear strain.
