Do the homologous chromosomes separate during meiosis 1 or meiosis 2?
Homologue matches separately during the first round of cell division, called meiosis I. Sister chromatids separate during a subsequent round called meiosis II. Since cell division happens two times during meiosis, one beginning cell can deliver four gametes (eggs or sperm).
The homologous chromosomes separate into various cores during meiosis I, causing a decrease in the ploidy level in the principal division. The second division of meiosis is more like a mitotic division, then again, actually, the little girl cells don't contain indistinguishable genomes as a result of hybrid.
There are two divisions in meiosis; the principal division is meiosis I: the quantity of cells is multiplied however the number of chromosomes isn't. This outcome in 1/2 has numerous chromosomes for every cell. The subsequent division is meiosis II: this division is like mitosis; the quantity of chromosomes doesn't get diminished.

Which statement about DNA replication is FALSE?
A). Because the two strands of parental DNA run in opposite directions, the new strands must be made in different ways.
B). The lagging strand is made of a series of pieces that must be joined together to make a continuous strand.
C). DNA polymerase builds a new strand by adding DNA nucleotides one at a time.
D). DNA ligase adds nucleotides to the lagging strand.
E). The two strands of parental DNA are separated during DNA replication.
DNA ligase does not add nucleotides to the lagging strand and instead joins the pieces of strands together.
DNA replication is basically the process by which an organism replicates its DNA. DNA replication plays a very vital role in the process of inheritance.
The two strands, the leading and the lagging strand, of the DNA run in opposite directions and hence the new strands must be constructed in different ways. The lagging strand is made in a series of pieces which must be ligated together to make a continuous strand. The nucleotides are added one at a time by DNA polymerase. DNA ligase performs the function of ligating or joining the pieces of lagging strands together and does not add nucleotides.
Hence, option D is the correct option.

Gliding and condyloid joints are the two main types of synovial joints in the human body. Gliding joints are located in between flat bones, such as those found in the ankles, wrists, vertebrae and jawbone.
These small joints enable a smooth gliding motion when motion is applied. Condyloid joints consist of an oval-shaped end of a bone fitting into another oval-shaped concave surface on another bone; this type of joint has wide range movements, enabling flexing and extending motions to occur. They can be found at the wrist and elbow joints, where the radius or ulna meets proximal carpals or humerus respectively.

- Interphase: in this phase the duplication of DNA and organelles in the cell will be generated
- Prophase: DNA condensation is generated, then forming chromosomes.
- Prometaphase: the nuclear envelope dissolves and microtubules begin to spread into the space of the cell.
- Metaphase: the centromeres begin to congregate in the equatorial plane, thus forming two poles in the cell
- Anaphase: the chromosomes are distributed equally in the two poles due to the traction of the microtubules

what is Aerobic fermentation?
Aerobic fermentation or aerobic glycolysis is a metabolic process by which cells metabolize sugars via fermentation in the presence of oxygen and occurs through the repression of normal respiratory metabolism.
Fermentation enables cells to produce chemical energy from the breakdown of sugar, e.g. glucose, without the help of oxygen. That gives anaerobic (obligate, facultative, or aerotolerant) organisms the advantage of thriving in anoxic (without oxygen) environments that would rather be harsh for aerobic organisms.
