The correct term to fill in the blank would be cortisol. In the context of stress hormones and the brain, cortisol has a profound effect on the hippocampus, a brain structure that plays a pivotal role in memory. Cortisol is classified as a steroid hormone which is produced by the adrenal gland. It is deemed as the stress hormone as it is released as a response to stress as part of the fight or flight process. From studies, cortisol was found to have effect on the hippocampus when present in high levels. It damage and kill the cells in that area of the brain. The hippocampus is the area of the brain that is responsible for the long term memory storage. So, when this part is damage then the storage for our memories would surely be affected.
Answer:
Meiosis 1 better mirrors the process of mitosis.
Explanation:
During the process of mitosis, the somatic cells of the body replicate to form two daughter cells which are identical to the parent cell. In meiosis I, two daughter cells are formed. During mitosis, diploid cells are formed. During meiosis 1 also, two diploid cells are formed. hence, these two processes are more similar as compared to mitosis II. in mitosis II, four haploid cells are made as a result of the division process.

Explanation:
Answer:
Post translation farnesylation may be defined as a type of prenylation in which the isoprenyl group is added to the cysteine residues of the protein. This modification is important for protein and membrane interaction.
Basically two types of amino acid are required for the farsenylation modification. The signal peptide sequence is the short amino acid sequence that targets the ribosome in the endoplasmic reticulum. The sequence is generally lysine, aspartic acid, glutamic acid and leucine. The second sequence must be Caax (C is cysteine, a is aliphatic amino acid and X consists of C terminal amino acid.
