Draw a diagram of the nitrogen cycle with labels describing the metabolic processes. Give examples of bacteria that carry out each of these metablic processes.

The sum of all physical and chemical changes that take place inside the cells of human body is known as Metabolism.

The organism uses the energy given off by respiration in cells to power its ongoing, enzyme-controlled metabolic activities for the production of new molecules. Transformation of glucose into starch, glycogen, and cellulose is one example of a metabolic process.

A living thing's metabolism is the culmination of all the chemical activities that occur inside each cell and supply the energy for both essential functions and the synthesis of new organic substances. The ability to draw energy from their surroundings and utilise it for tasks like movement, growth and development, and reproduction makes living things special.

The first stage of photosynthesis involves energy molecules and the second stage this energy for sugar molecules formation.

 Phase I begins with the conversion of solar energy into chemical energy in the presence of water, which is subsequently stored as ATP and NADPH. At this point, oxygen is also emitted as a waste product. In phase II, carbon dioxide is combined with chemical energy from ATP and NADPH to produce glucose. Organelles in plant cells are referred to as chloroplasts. Grana are stacks that are present in each chloroplast and are found in the chloroplasts. The grana are made up of membranes called thylakoids that resemble sacs. These membranes include photosystems, which are assemblages of molecules that contain chlorophyll, the green pigment.

Answer:

A. law of harmony

Explanation:

During prophase 1, replicated homologous chromosomes pair up and undergo synapsis. the following testable question is generated regarding synapsis and genetic variability is that, " is the distance between two gene loci related to crossover rate?"

By recombining combinations of gene alleles on a single chromosome that always segregate together, synapsis and crossing-over mechanisms increase genetic diversity. A synapsis is formed by the joining and pairing of homologous chromosomes. This occurs during the first stage of meiosis, known as prophase I.

Mutation (which can generate completely new alleles in a population), random fertilization, random mating, and recombination among the homologous chromosomes during meiosis (which reshuffles alleles inside an organism's offspring) can all cause genetic variability.

The likelihood of a crossover among two genes is proportional to their distance apart. That is, the greater the distance between two genes, the more likely it is that they will cross over during meiosis.

Antigen presented on a MHC class II molecule. The antigen is delivered by the B-cell antigen receptor to intracellular locations, where it is broken down.

Sent back to the surface of the B-cell as peptides attached to MHC class II molecules. Armed helper T cells that are specific for an antigen can recognise the peptide: MHC class II complex, inducing them to produce proteins that cause the B cell to multiply and its offspring to develop into cells that secrete antibodies. In the absence of assistance from T cells, some microbial antigens can directly activate B cells. Many significant bacterial infections can be quickly responded to thanks to the B lymphocytes capacity to react directly to these antigens. However, the interaction of antigen-stimulated B cells with helper T cells and other cells is necessary for somatic hypermutation and switching to specific immunoglobulin isotypes.

Active transport is a energy dependent process. It requires an input of ATP.

In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. An input of energy is required in the process of active transport as it involves the movement of ions or molecules across a cell membrane from low to high concentration. The movement requires energy to maintain the electrochemical gradient. The uptake of glucose in the intestine of the human body and also the uptake of minerals or ions into the root hair cells of the plants are some of the examples of active transport. There are two types of active transport namely – Primary active transport and secondary active transport.

When cyanobacteria living in the oceans started producing oxygen through photosynthesis, it led the evolutionary innovation that resulted in the Great Oxygenation Event.

The Great Oxidation Event resulted from the presence of free oxygen in the atmosphere of Earth. The oxygen produced by cyanobacteria, which was utilized by multicellular creatures as early as 2.3 billion years ago, provided the catalyst for this.

The physiologically caused emergence of dioxygen (O2) in the Earth's atmosphere is known as the Great Oxygenation Event (GOE; also known as the Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or Great Oxidation). It essentially involves adding oxygen to the atmosphere. It is regarded as the first mass extinction as well.

Huge areas of the ocean gradually became oxygenated as a result of the cyanobacteria's constant emission of oxygen. The methane and oxygen that had built up began to react as the oxygen slowly started to escape into the environment. Methane was gradually displaced as more oxygen leaked, and oxygen replaced methane as a primary atmospheric constituent.

Genetic recombination via Crossing over and independent assortment of gametes are the 2 main processes that occur during meiosis that explain why there is so much diversity between individuals of the same family and within the same species.

The physical breakage, exchange, and rejoining of two DNA molecules is known as genetic recombination. In bacteria, several different pathways can mediate homologous or general recombination. RecA protein is required for each of these pathways to align the DNA molecules between regions of significant DNA sequence identity.

Crossing over is a cellular process that occurs when identical chromosomes line up during meiosis. Parts of the chromosome can be switched when two chromosomes — one from each parent — line up. The same genes may exist on both chromosomes, but in different forms.

Alleles from two (or more) different genes are sorted into gametes independently of one another, according to Mendel's law of independent assortment. In other words, a gamete's allele for one gene has no effect on the allele received for another.

Recombination is the process that occurs during meiosis in which pieces of DNA are broken and recombined to create new combinations of genes. During meiosis, chromosomes randomly move to separate poles. This process is known as independent sorting.

Genetic recombination is a process that occurs during meiosis (cell division that results in gametes). During this process, homologous chromosomes combine to form units known as tetrads. Chromosomes then cross over and exchange genetic material, creating new combinations of alleles. Recombination mixes pieces of the maternal and paternal genes together so that the genes can be classified independently.

After meiosis, gametes have 23 chromosomes, but independent arrangement means that each gamete has one of many different combinations of chromosomes. Different genes and alleles are inherited independently, according to the law of independent classification within sexually reproducing organisms. Chromosomes separate into multiple gametes during meiosis. The crossover process rearranges the linked genes on the chromosome. Mendelian bicrosses are a good example of independent assortment.

Sexual reproduction has several advantages over asexual reproduction. For one, it allows for a greater variety in the genetic material of the offspring.

The parents can pass on different combinations of genes, which results in a greater variety of traits in the offspring. This diversity can help the species adapt and survive in changing environments.

Another advantage of sexual reproduction is that it allows for the recombination of genetic material, which can help the species evolve and become more adapted to different conditions. Recombination occurs when two different sets of genetic material are combined. Finally, sexual reproduction allows for the formation of new species.
