2. Taking
Explanation:
Food chain is a linear relationship between organisms that depicts the flow of energy from one organism to another. In a food chain, organisms are arranged in trophic levels where arrows pointing to the right direction (➡) are used to show that the organim the arrow is pointing to eats the organism behind it.
Hence, according to this question, arrows in a food chain point from the organism SUPPLYING the energy to the organism TAKING the energy.
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.
Answer:
Generally proteins are denatured at high temperature.Therefore when the egg is hard boiled they are denatured since eggs are protein, the 3-dimensional structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the orderly arrangements of disulphide bonds in proteins are disrupted , which results in the formation of inter chains bonds among disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption and formation of a macro molecule.
However, the addition of reducing agent , breaks the covalent disulphide bonds. While detergent breaks the interchain bonds among the disulphide bonds. (The noncovalent bonds),These combined effects untangled the mesh networks of polypeptides formed, and reduces the hardened nature,

Fibrin is involved in shrinking clots which is also apart of "hemostasis" and wound healing. It has the ability to protect tumors from cells immune to cancers.
