Answer:
1. Chromatin condense into chromosomes.
4. Homologous chromosomes pair up (formation of tetrads).
5. Homologous chromosomes separate and move to poles.
2. Sister chromatids separate.
3. Chromosomes unravel in to chromatin.
Explanation:
This question portrays the process of meiosis in a cell. The ordered sequence of events in the options are:
1. Chromatin condense into chromosomes - This process occurs in the Prophase stage. Prior to the cell division, the nuclear material is found as Chromatin material. This Chromatin material then undergoes condensation to form visible chromosomes.
4. Homologous chromosomes pair up (formation of tetrads) - This process also occurs during the Prophase stage of meiosis I. In this stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) are paired up side by side to form a structure known as TETRAD or BIVALENT.
5. Homologous chromosomes separate and move to poles - This process characterizes the Anaphase stage of meiosis I. Homologous chromosomes are pulled apart to opposite poles of the cell by spindle microtubules.
2. Sister chromatids separate - After meiosis I, meiosis II involving sister chromatids instead of homologous chromosomes follows. In the Anaphase stage of meiosis II specifically, sister chromatids are pulled apart towards opposite poles of the cell.
3. Chromosomes unravel in to chromatin - After the whole division process i.e. karyokinesis (division of the nuclear material), the chromosomes begin to unravel to form the CHROMATIN threads once again. This process occurs in the Telophase stage of meiosis.
Nitrifying bacteria gets nitrogen from the air and turns it into nitrogen that is available for plant use. This can be seen in the nitrogen cycle which may be useful to you
Answer:
The cells (Osteoclasts) are found i believe around the bone to protect it from breaking or if it already is broken those cells help remodel or fix it back in place
Hope this helps
Explanation:
Answer: Peptide bond
Explanation: A peptide bond is the covalent chemical bond bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme integrated into the growing chain.
In the elongation stage ie when Long chain polypeptides are forming , peptide bonds are formed by linking many amino acids to each other. These peptide bonds of amino acids are relatively unstable, and can break spontaneously in a slow process as can be seen especially in enzymes of living organisms in the making and breaking of bonds.
Answer:
Anabolism builds molecules required for the body's functionality. The process of catabolism releases energy. Anabolic processes require energy. ... Examples of catabolic processes are proteins becoming amino acids, glycogen breaking down into glucose and triglycerides breaking up into fatty acids.
