Answer:
C.
Explanation:
Human reproduction is any form of sexual reproduction that results in fertilisation by humans. It normally includes a man and a woman having sexual intercourse. During sexual intercourse, the contact between male and female reproductive systems leads to the woman's ovum being fertilised by the man's sperm.
In human fertilization, a hapoloid ovum is released that fuses with a haploid sperm and produces a single 2n diploid cell called the zygote.
Hence, the correct option is C.
Answer:
Growth of cell and replication of DNA.
Explanation:
The cell cycle has three stages, the interphase, mitosis, and the G0 phase.
Interphase is before mitosis, and it prepares the cell for its division. Interphase has three phases:
- G1, where the cell grows in size due to the growth of organelles and components, which the cell will need later.
- In the S phase, the cell synthesizes a copy of the DNA.
- The G2, where the cell keeps growing and producing organelles and other elements that will need for mitosis.
In conclusion, in the interphase, the cell grows and replicates its DNA.

Last one
Explanation:
since Osmosis is the diffusion of water. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower concentration is hypotonic. Solutions of equal solute concentration are isotonic
In photosynthesis, the mitochondria use both CO2 and H2O to produce glucose (a carbohydrate)
Answer:
Socrates will always question any man with a reputation for wisdom. He wanted he/she to examine his/her live and become aware of their own ignorance rather than thinking that they know things when actually they know nothing.
The three classes of people Socrates questioned were the politicians, Poets and craftsmen.
He found all three lacking in the real wisdom (Higher Things or Human Excellence) as they only possessed human wisdom in their respective trades.
