<span>B. Bending of light decreases
</span>According to the law of reflection, it stated that when light strikes
the boundary between different media, a portion of the light is reflected while
another portion enters the medium. Thus, the process in which the ray of light
crosses the boundary and enters the second medium is known as refraction.
However, the velocity of light decreases when light enters a denser medium.
Skin cancer is the one I can think of
What is a germ cell mutation?
A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ovum). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.
What is affected in a germ cell mutation?
Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs). Somatic mutations are frequently caused by environmental factors, such as exposure to ultraviolet radiation or to certain chemicals.
Answer:
C
Explanation:
when there is limited food, then natural selection will occur
Explanation:
Many invertebrate animals cant survive in water that has been polluted and resulted in a lowering of oxygen concentration so the presence or absence indicates the extent to which a body of water is polluted.
Lichens can be used to indicate air pollution as they grow exposed to places such us rocks and tree barks. They need to be efficient at absorbing water and nutrients to grow there. Rain water contains enough nutrients to keep them alive. Air pollutants dissolve in rain water especially sulfur dioxide can damage lichens and prevent them from growing. This makes them a natural indicator of air pollution.
