What is the correct order of events in mitosis ?

The cell cycle is a four stage procedure

The period between cell divisions is represented by the stages G1, S, and G2, which together make up interphase. An individual cell "decides" whether or not to join the cell cycle and divide based on the stimulatory and inhibitory signals it receives.

Checkpoint signalling systems and specialised proteins are used by cells to guarantee correct cell cycle progression. DNA damage is checked for before and after S phase at checkpoints at the end of G1 and the start of G2. Similar to this, a checkpoint in mitosis makes sure that the chromosomes are properly separated in anaphase before the cell's spindle fibers are properly aligned in metaphase.

Hence, cell cycle is sequence of event in organized manner.

Gene expression changes cause cell differentiation.

Cell differentiation is the process by which undifferentiated embryonic cells become specialized cells. This happens as a result of a process known as gene expression.

Gene expression refers to the specific combination of genes that are turned on or off (expressed or repressed), and it determines how a cell functions. Gene expression is triggered by signals in your body, both inside and outside of your cells.

Gene expression refers to the process by which information from a gene is used to build the structures of a cell. Because RNA translates and transcribes the DNA code into proteins (cell structures), it also aids in cell differentiation.

Gene expression is a tightly controlled process that allows a cell to respond to changes in its surroundings. It functions as an on/off switch to control when proteins are produced as well as a volume control to increase or decrease the amount of proteins produced.

Answer:

D) Sun

Explanation:

The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Combustion is an organic material reaction to burning in the presence of oxygen. It is the process of conversion to the carbon cycle.

The earth must sustain its current level of carbon. The carbon cycle keeps this going.

Plants use the carbon from the atmosphere, which is then passed to mammals. Carbon dioxide is released into the atmosphere when animals breathe.

Additionally, after spending a long time in the soil, plants and animals perish and turn into fossil fuels. The carbon dioxide in the atmosphere is then released once they are burned.

Due to the massive amount of fossil fuels burned, a level of carbon dioxide that is above normal is released.

This is causing many respiratory disorders and ocean acidification.

Answer:

Helicase malfunctions can have negative effects on one's health. Mutations that prevent helicase function have been associated with cancer and several genetic disorders, including xeroderma pigmentosum and Werner syndrome, which induce rapid aging (a photosensitivity disorder caused by a defect in DNA repair).

Cancer and genetic illnesses including xeroderma pigmentosum and Werner syndrome, which accelerate aging, are linked to helicase mutations (a photosensitivity disorder caused by a defect in DNA repair).

DNA helicases are enzymes that break the hydrogen bonds that are responsible for keeping the two strands of double-stranded DNA connected to one another. The creation of the single-stranded DNA that is required as a template or reaction intermediate in DNA replication, repair, and recombination is the end consequence of this unwinding reaction, which requires a significant amount of energy.

Cancer as well as various other hereditary illnesses, such as xeroderma pigmentosum and Werner syndrome, both of which cause premature aging, have been linked to mutations that prohibit helicase from functioning properly (a photosensitivity disorder caused by a defect in DNA repair).

Answer:

Copious watery saliva is secreted in response to parasympathetic stimulation and thicker saliva in response to sympathetic stimulation. Other factors affecting saliva composition are flow rate, circadian rhythm, duration of stimulus, nature of stimulus and diet.

When the parasympathetic nervous system is stimulated, copious watery saliva is secreted, and when the sympathetic nervous system is stimulated, thicker saliva is secreted.

In addition to flow rate, circadian rhythm, stimulus duration, stimulus nature, and diet, saliva composition is also affected by flow rate and circadian rhythm.

In sleep, major salivary glands secrete very little saliva, and the majority of saliva is secreted by minor salivary glands. Saliva concentration is determined by the rate of flow, not stimulus type.

The daily normal production of saliva with or without food is between 0.5 and 1.5 liters. The whole unstimulated saliva flow rate is approximately 0.3-0.4 ml/min. It decreases to 0.1 ml/min during sleep and increases to 4, 0-5, 0 ml/min during eating, chewing, and other stimulating activities.

The alleles of the various genes that each individual chromosome carries are mixed and matched traits with regard to one another, resulting in a distribution of traits.

When comparing populations, differences are typically seen as variations in the frequency distributions of the states (or kinds) of a certain feature (or set of traits). As a result, if two or more populations exhibit the same trait states at the same rates, they are said to be identical. A population's variance and pattern of attributes are influenced by both genetic and environmental variables. During meiosis, chromosomes can switch sections, causing mutations brought on by environmental factors, mistakes in DNA replication, or both.
