Sexual reproduction in humans ________. Question 5 options: combines two diploid gametes, producing a zygote produces an individ
tekilochka [14]

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.

Assume hydrolysis of ATP proceeds with G = -30 J/mol. RT = -2.5ATP + H2O -> ADP + PiWhich expression gives the ratio of ADP t
zavuch27 [327]

Answer: (d) e^12

Explanation:

<em>The relationship between the standard free energy change, </em>ΔG, and the equilibrium constant, K at a particular temperature is represented<em> Using the formula</em> ΔG = -RTlnK, where G = -30, RT = -2.5 and [Pi] = 1

lnK = ΔG/-RT

lnK = -30/-2.5

lnK = 12

<em>taking exponents of both sides</em>

e^(lnK) = e^12

K = e^12

DNA is replicated in the nucleus of eukaryotes, but in the cytoplasm of prokaryotes. Why is this?
umka2103 [35]

Answer:

In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

   In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that  transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
