Answer:
B. Oncogene
Explanation:
A gene that makes the body cells to divide in an uncontrolled manner is called an oncogene. An oncogene is responsible for the development of tumors due to disturbed regulation of cell division. The gene src makes the cells to enter the process of cell division in response to the growth factors.
However, the mutant src gene does not require the presence of growth factors and signals the cells to enter the process of cell division even in the absence of the growth factors. Since the mutant src gene causes uncontrolled cell division, it represents an oncogene.
Answer:
As the white light moves through the two faces of the prism, the different colors bend different amounts and in doing so spread out into a rainbow. In a rainbow, raindrops in the air act as tiny prisms. Light enters the raindrop, reflects off of the side of the drop and exits.
They replicate fast - producing more of the useful proteins such as the hormone insulin.
As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
<h3>
What is Kepler's second law?</h3>
Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.
This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.


From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

Answer: The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.
