What is the correct order of the following events in Eukaryotic gene expression? 1. translation 2. mRNA processing 3. transcription3,1,21,2,33, 2,12,1,3
Answer is 3,2,1 .Information travels from DNA to RNA to protein during the expression of a protein-coding gene. The Eukaryotic gene is undergoes transcription and then mRNA processing and then it translated.
A Eukaryotic gene expression results in the production of the appropriate protein, and this complex process comprises two main phases. Transcription is the process by which the data in DNA is converted into a messenger RNA (mRNA) molecule in the initial phase. An enzyme called RNA polymerase II catalyzes the synthesis of a pre-mRNA molecule during transcription by acting as a template for complementary base-pairing. Mature mRNA is subsequently produced by processing the pre-mRNA, which is done through the process of transcription. A single-stranded copy of the Eukaryotic gene is produced as mRNA, which must then be translated into a protein molecule.

Dog noses do more than just sniff the roses. Dogs use their senses of sight and scent to navigate their environment and interact with others, whereas humans rely solely on their eyesight.
Olfactory information is not as time-consuming to interpret as visual information. Dogs are the complete opposite. Dogs are thought to have a sense of smell that is 1,000–10,000 times greater than that of humans. Dogs put a lot of effort into interpreting odors.

if the amount of food or resources available increases, the carrying capacity for an animal; which is an accurate description of the growth of a natural animal population?
Carrying capacity is defined as the average population size of a species in a given environment. Environmental factors such as adequate food, shelter, water, and mates limit the species population size.
If these requirements are not met, the population will decline until the resources recover.
If a species' population surpasses its carrying capacity, the ecosystem may become unfit for survival.
If the population outnumbers the carrying capacity for an extended period of time, resources may be depleted completely. If all resources are depleted, populations may perish.
Carrying capacity, or the greatest number of people that an ecosystem can support over time without harming or deteriorating it, is controlled by three essential factors: food supply, water availability, and space.2

One of the best known examples of classical conditioning may be Pavlov's experiments on domestic dogs. Russian behaviorist Ivan Pavlov noticed that the smell of meat made his dogs drool. He began to ring a bell just before introducing the meat.Classical conditioning is biologically adaptive because it builds learned reflexes to different environmental stimuli off of biological, unlearned ones and so adapts to its environment.The principles of classical conditioning are:

Where do cells come from?
A. the nucleus
B. spontaneous generation
C. other cells
Answer:
Explanation:
Cells come from other cells. Specifically, cells can be produced through a process called cell division, in which a parent cell divides into two or more daughter cells. There are two main types of cell division: mitosis and meiosis.
During mitosis, a parent cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. This process is important for the growth and repair of tissues in the body.
During meiosis, a parent cell divides into four non-identical daughter cells, each with half the number of chromosomes as the parent cell. This process is important for sexual reproduction, as it produces the sperm and egg cells that are necessary for the creation of a new organism.
In summary, cells are produced through the process of cell division, which can occur through either mitosis or meiosis.
Answer:
The answer is C: other cells.
All cells come from other pre-existing cells. Cells divide through processes of mitosis and meiosis (depending on if it is a somatic or a zygote cell).
