When the art of one age has so defined the characteristics of human beings that it can speak eloquently to another age, we call this universal. The most numerous and ubiquitous species of primates, humans (Homo sapiens) are distinguished by their bipedalism and enormous, complex brains. This has made it possible for the advancement of culture, language, and tools.
Humans are highly social creatures who want to live in elaborate social systems made up of a variety of coexisting and conflicting groupings, ranging from families and kinship networks to political states. Human social interactions have produced a vast range of values, social conventions, and eloquently that support human society.

Deviant drug use is not common within a social group and that is disapproved of by the majority.
What is a deviant usage of drugs?If substance abuse is characterized as an illness or a crime, the loss of control linked to addiction is regarded as aberrant behavior that deviates from accepted social norms. Drugs that have been labeled addictive also have the ability to make users fearful as a preventative measure. There has been an attachment made between heredity and the idea of deviation, which appears to be more remote from a biological reason. Deviance was often believed to have genetic roots in the nineteenth century.

In the same science fair, Tina asks the question "Does caffeine
increase the
heart rate of an earthworm?" In Test 1, she measures
the heart rate by looking at the earthworm under a microscope, the
earthworm has a heart rate of 50 bpm (beats per minute). In Test 2,
she places a few drops of caffeine on the earthworm's skin and
measures the
rate again. In this test, the heart rate is 68 bpm.
6) What is the manipulated variable?
How many drops of caffeine she drops on the worm is the manipulated variable.
In an experiment, the independent variable is a manipulated variable. Due to the fact that you may alter it, it is termed the "manipulated" one. In other words, you can choose in advance whether to raise it or lower it. Only one variable should be changed at a time throughout an experiment.
The Independent variable is Caffeine's impact. the production and use of nitrogen fertilizers, as well as the burning of fossil fuels in autos, power plants, and industries, are dependent variables that are local in scope. the heart rate of the worm is the responding variable in this experiment.
When an earthworm is given a stimulant like caffeine, its heart rate rises. Does coffee make an earthworm's heart beat faster? is the research topic upon which the experiment is based. The effect of coffee is the independent variable in this research question, and the response it causes is a change in heart rate (the dependent variable) This brings us to the following theory: "If an earthworm is given a stimulant like caffeine, then its heart rate accelerates."

smooth muscle is typically found in:
e. stomach and intestine
The walls of hollow organs like the stomach, intestines, bladder, and uterus, as well as the walls of passageways like blood and lymph vessels and the tracts of the respiratory, urinary, and reproductive systems, are all made of smooth muscle.
An example of a smooth muscle found in the eyes is the ciliary muscle, which also affects the lens's shape by expanding and contracting the iris.
In response to cold temperatures, smooth muscle cells in the skin, such as those of the arrector pili, cause hair to stand upright.
Definition Smooth muscle:
Different systems use smooth muscle, a type of muscle tissue, to exert pressure on organs and arteries. Sheets or strands of smooth muscle cells make up smooth muscle.
Actin and myosin fibers that run through these cells are supported by a scaffolding of other proteins. When ATP is released for utilization by the myosin, smooth muscle contracts as a result of the stimulus. In contrast to the "on-or-off" contraction of skeletal muscle, the amount of ATP released by smooth muscle is proportional to the intensity of the stimulus.

Which of the following is not cause by human interaction with the earth system
Answer:
Answer: C. mountain building
Air pollution, water pollution and deforestation are caused by human interaction with the earth system. Air, water and forests are abiotic (non-living) factors of the environment on which human population is dependent upon. Release of pollutants in the air and water due to human activities causes pollution. Forests are removed in order to derive resources like wood, medicines and for urban development hence, causes deforestation. Mountain building is a nature induced process and is not caused by human interactions with the earth system. Mountain formation is a geological process, which is caused by large scale movement of the earth's crust. Mountains are formed by folding and faulting of the earth's crust and due to volcanic activity.

A mechanism that generates musical vibrations and launches them into the air is called a(n) _____.
Mechanism that generates musical vibrations and launches them into the air is called an aerophone.
What is an aerophone?An aerophone is a musical instrument that generates sound by causing air to vibrate without the use of any type of strings or membranes and without the vibration of the instrument itself that add the sound. Whistles, blowholes, cup mouthpieces, reeds, organs, and the free aerophone are the six types of aerophones. With the vibration of air, the sound is produced which makes the mechanism of aerophones.
We know that many instruments make vibration when the musician strikes the strings. The trumpets, tuba, harmonica, horn, accordion, clarinet, piccolo, flute, saxophone, accordion and whistle are the examples of Aerophone. These instruments sound very good when they are played as a band as compared to sole performance.

How does the bottleneck effect undermine the effort of conservation biologists who are trying to save species nearing extinction?.
The bottleneck effect undermines the effort of conservation biologists who are trying to protect species nearing extinction by events such as floods, earthquakes, human habitat devastation, and drought can cause a population to drastically decline.
The bottleneck effect can undermine the conservation of efforts of biologists who saves species near extinction when the population’s size is drastically reduced due to environmental factors including starvation, earthquakes, floods, fires, disease, and droughts as well as human behaviors like speculative killing, widespread violence or planned to cull, and human population control. As a result, a smaller population with less genetic diversity is left to transmit genes to future generations of offspring through sexual reproduction.
Such events can reduce the variation in a population’s gene pool. Genetic diversity continues to be reduced, only gradually rising over time when random mutations take place or only when gene flow from another group happens.

The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode.

1) introns
2) exons
3) repressors
4) enhancers
5) integrators
Option 1: In expressing the mammalian genes in e.coli, the most formidable obstacle is Introns.
Introns are the nucleotide sequences that do not directly code for proteins. They reside in the genes of an organisms and are generally removed during transcription of an RNA molecule.
Our DNA comprises exons and introns, where exons are coding parts while introns are non-coding parts. Introns get stuck in between which leads to stopping the coding of DNA because it does not form any kind of protein. These are like gap which is not coded for protein. So to avoid this obstacle we replace it with exons by the process of splicing. This is because exons form proteins and thus can participate in DNA coding (as DNA is responsible for the synthesis of proteins). These are found in all creatures and all types of genes.
