Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.
a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere
b) all organisms are descended from one or a few common ancestors
c) the genetic code readily evolves by natural selection
d) there's only one possible way to encode information in a macromolecule
Answer:
b) all organisms are descended from one or a few common ancestors
Explanation:
Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.

But we've never been to the planet's core. We haven't even come close. The central point of the Earth is over 6,000km down, and even the outermost part of the core is nearly 3,000 km below our feet.Aug 13, 2015
The correct answer is option (A) Chlamydia.
A typical sexually transmitted illness is chlamydia. Both men and women are susceptible. However, compared to men, women are typically more negatively impacted by its consequences.
Symptoms and reasons for Chlamydia
- Chlamydia symptoms are sometimes mistaken for those of other diseases that afflict women.
- Some signs, such vaginal ulcers, are difficult to see, making the infected unaware that they have the disease.
- If addressed, this can result in even more serious issues including pelvic inflammatory disease, which then might have an impact on fertility.
- It may harm a woman's reproductive system permanently. Later it becomes challenging for women to get pregnant as a result. Additionally, chlamydia can result in an ectopic pregnancy that may be fatal.
