Answer:

Explanation:

The reaction that does not involve reduction-oxidation (redox) reactions is:

2H2O(l) → 2H2(g) + O2(g)

This is a decomposition reaction in which water (H2O) is broken down into its component elements, hydrogen (H2) and oxygen (O2). This reaction does not involve the transfer of electrons, which is a key characteristic of redox reactions.

Redox reactions are chemical reactions that involve the transfer of electrons between reactants, resulting in the oxidation of one species and the reduction of another. In these reactions, one reactant loses electrons (undergoes oxidation) while another reactant gains electrons (undergoes reduction).

Examples of redox reactions include the combustion of fuels, such as the burning of wood or coal, and the reactions that occur during photosynthesis and cellular respiration.

Molecule dissociates from the transmembrane receptor proteins in the ER thus activating the UPR is  c) BIP/Grp78

In general , BIP/Grp78 is a considered as the chaperone protein that gets associated with to newly synthesized proteins inside the endoplasmic reticulum.  BIP/Grp78  helps in the proper folding and minimize aggregation.

It is also known as Binding Immunoglobulin Protein (BIP) or Glucose-Regulated Protein 78 (Grp78). BIP/Grp78 comes from the family of heat shock proteins and is a member of the HSP70 family of proteins. Hence, during ER stress, BIP/Grp78 will dissociate from the transmembrane receptor proteins PERK, IRE1, and ATF6, allowing them to activate and initiate the UPR.

Hence , C is the correct option

Genetic drift is a mechanism of evolution that refers to the random fluctuation of allele frequencies in a population over time due to chance events.

Genetic drift occurs because not all individuals in a population will pass on their genes to the next generation, and by chance, certain alleles may become more common or less common in the population.

Over time, genetic drift can result in the loss of some alleles from a population, making it less diverse. In extreme cases, genetic drift can lead to the fixation of one allele, which means that all individuals in the population have that allele, and no other alleles for that gene exist in the population.

Genetic drift is one of the mechanisms of evolution, and it can lead to changes in the genetic makeup of a population over time. However, it is a random process, and it does not necessarily lead to adaptations that increase an organism's fitness or survival.

Erwin Chargaff discovered that the quantity of pyrimidines, such as cytosine and thymine, and purines, such as guanine and adenine, are always equal.

According to Chargaff's rules, DNA from every cell of any organism should have a ratio of 1:1 of purine and purine bases. More specifically, the amounts of guanine and adenine should be equal to nucleotides and thymine, respectively. This phrase alludes to the work of Columbia University biochemist Erwin Chargaff. DNA always includes equal amounts of guanine, cytosine, adenine, and thymine, according to Chargaff's analysis of the ratios of the four types of base units in the late 1940s. Moreover, there should be a 1:1 molar ratio ratio between the purine & pyrimidine bases (A+G=T+C). The nitrogenous bases adenine, thymine, cytosine, & guanine are all present in DNA. Both adenine and thymine always bind with cytosine, and vice versa. As some nucleotides are always found in pairs, their percentages in the DNA will be equal.

The discovery of ribozymes added weight to the RNA world hypothesis by demonstrating that RNA molecules may perform catalytic tasks in the absence of proteins.

According to the RNA world hypothesis, early life on Earth was based on RNA rather than DNA or proteins. According to this theory, RNA was the first self-replicating molecule capable of catalysing chemical processes required for life. These RNA molecules developed throughout time into increasingly sophisticated forms, giving rise to the DNA-based life we see today.

The discovery of ribozymes, which are RNA molecules capable of catalysing chemical processes, offered compelling evidence in support of the RNA world concept. It demonstrated that RNA can function as both a genetic material and a catalyst, implying that RNA molecules may have played an important part in the development of life on Earth.

The walls of capillaries contain only the endothelial layer, allowing for rapid gas and nutrient exchange between the blood and tissues.

A thin layer of cells called the endothelium layer covers the inside surface of capillary walls. Due to the thinness of this layer—just one cell—nutrients and gases can diffuse between the blood and surrounding tissues effectively. As a result, waste materials like carbon dioxide can be eliminated and nutrients and oxygen from the blood can be exchanged with the tissues. Capillaries are extremely effective at carrying out their role because of their modest size and the fact that they have just one layer of endothelial cells.

The cleavage furrow of animal cells is formed with the help of a constricting belt made of the protein actin and myosin.

During cell division, the cytoplasm of the cell is divided into two daughter cells through a process called cytokinesis. In animal cells, cytokinesis is achieved through the formation of a cleavage furrow, which is a constricting ring that pinches the cell membrane inward until it separates the two daughter cells.

The cleavage furrow is formed by the action of actin and myosin, which are two types of contractile proteins. Actin forms a ring-like structure just inside the cell membrane, and myosin binds to the actin filaments and uses energy from ATP to move along the filaments and contract the ring. This contraction of the actin-myosin ring causes the cell membrane to be pulled inward, forming the cleavage furrow.

Overall, the formation of the cleavage furrow is a critical step in animal cell division, and it is achieved through the coordinated action of actin and myosin proteins.
