Papain and bromelain are both proteolytic enzymes, which means that they help break down proteins. Specifically, they hydrolyze or cleave peptide bonds between amino acids in proteins.

By breaking down the proteins in meat, these enzymes can help to tenderize it, making it easier to chew and digest. Plant enzymes (such as papain, bromelain, and ficin) have been studied extensively as meat tenderizers. Novel plant proteases (actinidin and zingibain) and microbial enzyme preparations have recently piqued the interest of researchers due to their ability to manage meat tenderization and other benefits.

The correct description regarding how the majority of oxygen is transported to cells and tissues is by binding to hemoglobin in red blood cells. Oxygen can be transported in the blood in two ways: dissolved in the plasma or chemically bound to the protein hemoglobin in red blood cells.

Hemoglobin is an iron-containing protein in red blood cells that binds to oxygen and carries it from the lungs to the body's tissues and organs. Hemoglobin is the most abundant protein in red blood cells, and each hemoglobin molecule can bind up to four oxygen molecules.

When oxygen binds to hemoglobin, it forms oxyhemoglobin, which is a bright red pigment. This is why oxygen-rich blood is bright red in color.

The majority of oxygen is transported to cells and tissues by binding to hemoglobin in red blood cells. This process is known as oxygen transport, and it is essential for delivering oxygen to all parts of the body.

A pair of chromosomes inherited from the mother and the other pair from the father is called a homologous chromosome pair.

Homologous chromosomes are similar in size, shape, and gene content and carry the same genes at the same loci, although the specific alleles may differ. In humans, the homologous chromosome pairs form the 23 pairs of chromosomes that contain the genetic material necessary for the development and functioning of the organism.

During sexual reproduction, each parent contributes one set of chromosomes, including one member of each homologous chromosome pair, to their offspring. The process of meiosis ensures that each gamete receives one member of each homologous pair, resulting in genetic diversity in the offspring.

This means that the genetic material inherited from the mother and father are combined in their offspring, leading to genetic variation within a population. The study of homologous chromosomes is essential for understanding genetics, inheritance patterns, and evolutionary biology.

The backbone of the DNA molecule is composed of sugar and phosphate groups. These components are connected by phosphodiester bonds, which alternate to form a long chain.

The correct answers to the question “Select the parts that make up the backbone of the DNA molecule” are a. Sugar and d. Phosphate. Sugar (deoxyribose) and phosphate molecules are the two primary components of the DNA backbone. The sugar and phosphate molecules alternate to form the long chain that makes up the backbone. The nitrogenous base, which is bonded to the sugar, extends away from the backbone and pairs with its complementary base on the opposite strand to form the DNA molecule's double helix structure. Nucleoside is a combination of a sugar molecule (ribose or deoxyribose) and a nitrogenous base. These components are used to create nucleotides. Glycine is an amino acid, which is a component of proteins, not DNA. The nitrogenous base is bonded to the sugar and extends away from the backbone, as mentioned above.

DNA polymerase is an enzyme that joins nucleotides to synthesize a new DNA strand during DNA replication.

The process begins with the separation of the double-stranded DNA molecule into two separate strands by an enzyme called helicase. One of the strands serves as a template for the synthesis of a new complementary strand. DNA polymerase reads the template strand and matches complementary nucleotides to it, adding them one by one in the 5' to 3' direction.

As each nucleotide is added, DNA polymerase catalyzes the formation of a phosphodiester bond between the 3' end of the growing DNA strand and the 5' phosphate group of the new nucleotide. This process continues until a complete new DNA strand has been synthesized.

The characteristics or adaptations the extinct organisms lack to not be able to survive during the triassic jurrasic period is adaptation for burrowing, specialized teeth, and dehydration resistance.

During the Triassic-Jurassic, extinct organisms lacked certain characteristics or adaptations that prevented them from surviving. The following are some examples of such characteristics or adaptations: Adaptations for Burrowing: Many Triassic species had evolved adaptations for burrowing that allowed them to escape harsh environments or predators. However, such adaptations did not help them survive the Jurassic era's drier and hotter conditions.

Specialized Teeth: Various Triassic species had specialized teeth to eat tough plants, which were abundant during that era. But, after the Permian extinction, new plant types emerged, and these specialized teeth did not allow these species to survive. Dehydration Resistance: Many Triassic species could withstand dehydration, which was a necessary adaptation in arid conditions. However, the Jurassic era had much drier and hotter conditions, which meant that the species could not withstand the new environmental conditions.

In summary, the lack of suitable adaptations for the new environmental conditions, particularly the drier and hotter conditions, was one of the main reasons why certain extinct organisms could not survive during the Triassic-Jurassic era.

The similar structure in different species that evolved separately is called a convergent structure.

The term “convergent structure” refers to the process by which distinct species with different ancestors develop similar structures, either through adaptation to similar environmental conditions or similar ecological roles.

This phenomenon, known as convergent evolution, typically results in different organisms developing similar adaptations to solve the same problem.

Both structures have evolved to perform the same task (flight), and both have independently evolved to do so due to selective pressure in a specific habitat.

A similar structure, shared by different species, is termed homology when it is derived from a common ancestor, and analogy when it is not.

Fermentation is a crucial pathway for providing cellular energy when oxygen is unavailable or in insufficient supply, as it allows cells to continue generating ATP by regenerating NAD+ and allowing glycolysis to continue.

Because it enables the regeneration of the oxidized form of the electron transport molecule NAD+, which is necessary for glycolysis to proceed, fermentation is a necessary mechanism for supplying cellular energy when oxygen is missing or in inadequate supply. Pyruvate is produced from glucose during glycolysis, and NAD+ is reduced to NADH. The electron transport chain's ability to convert NADH back into NAD+ in the presence of oxygen permits glycolysis to continue creating ATP. The electron transport chain, on the other hand, is unable to work when oxygen is lacking or insufficiently present, and NADH builds up, which can inhibit glycolysis.

By oxidizing NADH back to NAD during fermentation, NAD+ can be replenished, allowing glycolysis to continue generating ATP. Certain cells, like muscle cells and some microbes, can employ fermentation to make lactic acid or ethanol as end products in the absence of oxygen, allowing them to generate ATP without the need for oxygen.
