Ν= c/λ
λ= 486 nm * ( 1 m / 1x10^9 nm) = 4.86 x10^-7 m
v= (3.00 x 10^8 m/s) / (4.86 x10^-7 m)
v= 6.1728395x 10^14 s^-1
= 6.14 x10^-14 Hz
I believe the answer is B, as they only solely survive on tough and fibrous plant matter. Plants are producers because they can produce their own food instead of consuming something else to survive.
This process is known as fertilisation. Gametes contain half the number of chromosomes of all other cells in the organism. This means they are haploid . When the male and female gametes combine in fertilisation they create an embryo with the full complement of chromosomes (diploid).
Answer:
CaS calcium sulfide
Explanation:
hydroxides are insoluble except with group 1 like the lithium,
sulfides are insoluble in water and with calcium either
so CaS is insoluble
