Mitochondria and chloroplasts both contain their own nucleic acids which are separate to those contained in the nucleus of the cells which these organelles are contained.
The buffer was too acidic i.e when a blood film is viewed through the microscope, the RBCs appear redder than normal, the neutrophils are barely visible, and the eosinophils are bright orange.
<h3>What are buffer used for?</h3>
Buffers are employed to keep the pH of a solution steady because they can neutralize little amounts of extra acid or base. There is a specific pH range for a certain buffer solution and a predetermined amount of acid or base that can be neutralized before the pH changes. The buffer capacity is the maximum amount of acid or base that can be supplied to a buffer without causing a pH change.
As a pH value greater than 7.8 or lower than 6.8 might result in mortality, human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) to keep blood pH between 7.35 and 7.45.

Answer:
A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.
The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the homologous chromosomes.
The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.
This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.
