A reddish tinge in the cerebrospinal fluid indicates that there is internal bleeding, or hemorrhaging, or is a sign of spinal cord obstruction.
The cerebrospinal fluid (CSF) is a clear, colorless fluid found in the brain and spinal cord. The main function of this fluid is to cushion the brain and spine from impacts and blows and protect these vital components of the body.
Answer:
The correct answer will be-
1. Homologous recombination- crossing over
2. Occur-during pachytene of meiosis I of gamete formation.
Explanation:
The basis of diversity of organism present on earth lies in the sexual mode of reproduction possessed by the organism to produce offspring. The sex cells involved in the reproduction are formed by a process called meiosis.
During the formation of gametes, at the pachytene stage of meiosis I take place a mechanistically conserved process which leads to the exchange of DNA segment between non-sister chromatids called crossing over through a process known as homologous recombination.
This exchange of genetic material in the homologous chromosomes increase the genetic diversity of the organism on the earth.

Answer:
ATCGCGGGAA
Explanation:
The way I learned this was with the word "GCAT". G pairs with C and vise-versa and A pairs with T and vise-versa. This is how you know what the opposite chain of DNA will look like.
