Answer: The combining form for skull is crani/o.

Cranio refers to combining the form of a skull especially covering the brain.

In order to symbolize the term cranium, or the skull, specifically the portion that covers the brain, the combining form "Cranio-" is employed as a prefix.

It is regularly used in medical terminology, particularly in anatomy, sometimes referred to as the braincase the cranium is the portion of the skull that houses the brain.

The cranium is made up of facial bones and cranial bones, which surround and guard the brain spinal cord connects to the brain through a hole at the bottom of the skull.

Meiosis and Mitosis are both forms of cell division.

However, meiosis differs from mitosis in that it produces sex cells whereas mitosis produces somatic cells.

Meiosis occurs in the gonads while mitosis occurs in other body cells.

Cell division refers to the process by which the cells divide and produce new cells.

There are two forms of cell division, namely:

Meiosis is a form of cell division in which the chromosome number is halved as four daughter cells are produced from a single cell that divides.

Meiosis results in the production of sex cells which are haploid cells.

Meiosis occurs in the sex cells.

Mitosis is a form of cell division that results in the production of two daughter cells from a single parent cell.

In mitosis, the chromosome number is not halved, rather the cells produced are diploid cells.

Mitosis occurs in the somatic or body cells.

Photosynthesis: happens within chloroplasts, which are found in most plant cells. Inside this chloroplast, there are sacs called thylakoids. Chlorophyll, a light-absorbing molecule captures solar energy from light; most likely the sun. The captured energy is then converted into ATP and NADPH molecules, also known as chemical energy. The molecules then give off high-energy electrons, and the electrons then move through electron carrier proteins within the thylakoid membrane. The protein within the electrons pumps hydrogen ions into the thylakoid from the surrounding gel-like fluid inside the chloroplast called stroma The hydrogens that get pumped from the electrons then build up within the thylakoid space. The hydrogen ions move back to the stroma through a protein channel. The electron transport chain picks up high-energy electrons and hydrogen ions to form NADPH. The molecules then are able to carry high-energy electrons to the second stage of photosynthesis. As mentioned, chlorophyll molecules release high-energy electrons. The electrons then traveled through an electron transport chain and were then stored in NADPH molecules with hydrogen ions. For this to repeat the electrons and hydrogen ions must be replaced. A water-splitting enzyme removes electrons for the water molecules and then supplied them to the chlorophyll molecules. In doing so, the water molecules split apart into oxygen molecules and hydrogen ions. The ions and chlorophyll are now available for future cycles of light-dependent reactions. The oxygen is released into the air, ending the photosynthesis process.

A simple explanation:  The plant cells convert solar energy(sunlight) into food with the help of H20(water) and C02 (carbon dioxide) in turn in this process the plant releases oxygen.

Microorganisms are the microscopic organisms including microscopic organisms, archaea, protozoa, green growth, organisms, infections, and multicellular creature parasites (helminths). They can be either unicellular or multicellular and prokaryotes or eukaryotes. Additionally, they live in different kinds of environments. Of these microorganisms, archaea are prokaryotes, particularly living in outrageous conditions; a portion of these incorporate methanogens, halophiles, thermophiles, psychrophiles, and so on. In any case, protozoa are unicellular eukaryotes that acquire supplements through ingestion. Their cell wall is comprised of cellulose. Likewise, a few protozoans incorporate beats, ciliates, amoeboid, sporozoans, and so on.

Allele frequencies of a population can shift over generations due to genetic drift, a process of evolution (sampling error).

A population's allele frequencies can shift from generation to generation owing to random events, which is known as genetic drift. In more precise terms, genetic drift is a change that results from "sampling error" while choosing the alleles for the following generation from the gene pool of the current generation.

Purple sulfur bacteria uses hydrogen sulfide for reducing power.

Purple sulfur bacteria are a type of Proteobacteria that can photosynthesise. They are anaerobic or microaerophilic organisms that are commonly found in hot springs or stagnant water. They do not produce oxygen because, unlike plants, algae, and cyanobacteria, they do not use water as a reducing agent. Instead, they use hydrogen sulfide, which is oxidized to produce elemental sulfur granules. This can then be oxidized to produce sulfuric acid. Purple sulfur bacteria are classified into two families: Chromatiaceae and Ectothiorhodospiraceae, which produce internal and external sulfur granules and have different internal membrane structures.

Magnitude Estimation is a psychophysical procedure in which participants rate the perceived strength of a stimulus and assign numerical estimates to it.

The smallest observable difference between two stimuli, or the smallest change in a stimulus that may be appropriately assessed as different from a reference stimulus; this is also known as the difference threshold. MRI has become a standard tool in current neuroscience research because it allows for the correlation of brain structure (as determined by a structural, rather than a functional, MRI scan) and function in people. When a signal + noise distribution (SN) is detectably different from a noise distribution (N), the two distributions are separated by a distance termed d' (d-prime).

synovial joint are the bones separated by a narrow, fluid-filled, encapsulated space.

What is synovial joint?

Synovial joints enable motion. A thin layer of tough, smooth articular cartilage covers the surfaces of the bones where they come together to form a synovial joint. The two sides of the two cartilage-covered bone are separated and lubricated by a very thin layer of slick, viscous joint fluid known as synovial fluid.

The most typical joint in mammals is a synovial joint, which provides more range of motion for articulating bones than other joints like synarthroses, sutures, syndesmoses, or gomphoses. Anatomically, a synovial joint is a solid organ made up of bone marrow cells of all sorts, articular cartilage, synovium, perichondrium, and subchondral bone.

A neuron's ability to generate action potentials depends on the sodium entering the axon upon reaching the threshold and the opening of voltage-gated sodium channels.

Neurons are the cells in the brain that transmit instructions and information throughout the body and brain. Action potentials are electrochemical signals that travel the length of the neuron, and carry the information.

When an initial depolarization reaches a threshold, action potentials are triggered. When the inward sodium current is greater than the outward potassium current, this threshold potential occurs. It can be anywhere from 15 millivolts to the resting membrane potential of the cell. The membrane potential is depolarized by the net influx of positive charges carried by sodium ions, which causes voltage-gated sodium channels to open more. A positive feedback cycle that drives the membrane potential to a very depolarized level is brought about by the increased inward current supported by these channels, which results in further depolarization.

A decrease in the epigenetic methylation of DNA's cytosine and adenosine residues is known as hypomethylation (plural hypomethylations) in the field of genetics.

Cancer-related genes for the testicles include S100A4, mesothelin, claudin4, trefoil factor 2, PGP9. 5, POMC, and the heparinase gene. Other genes with hypomethylation and transcriptional activation are those for the testicles and trefoil factor 2. Classical oncogenes may be affected by gene region hypomethylation, which could contribute to oncogenesis, but research points to a greater involvement in the activation of genes involved in tumor invasion or metastasis. Hypomethylation, or decreased methylation, is a characteristic of tumor cells that can increase the activity of oncogenes.
