Answers
Answer:
bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

4) What factors influence the circulation of the Earth's atmosphere,
thereby producing our weather?
Answers
The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with seasonal variations in precipitation and temperature and Earth turning on its axis.
What is weather?The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.
Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answers
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.
The antibiotic rifampicin blocks transcription in many bacteria. In the presence of the antibiotic, adding sigma factor has no stimulating effect on RNA synthesis. A footprinting experiment on a rifamycin treated sample shows that the polymerase remains located at the promoter site in the presence of eNTPs and Mg2 ion. What step of transcription is rifamycin likely to block
Answers
Answer:
transcription initiation
Explanation:
Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:
1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.
2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence
3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).
In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.

Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.

Explanation:
Specific immunity involves targeting certain infections. This is done when certain cells assess the danger and release anti-bodies that target the antigens of the organism.
Once this is done, white blood cells will now be able to fight the organism or pathogen more efficiently.
There is therefore both a cell-mediated and antibody-mediated response.

The correct equation for the breakdown of ozone can typically occur in a series of two steps known as the destruction of ozone. It is illustrated thus;
Cl + O3 ⇒ ClO + O2ClO + O ⇒ Cl + O2The net reaction of the above process is the reaction of an oxygen atom with an ozone particle to form two molecules of oxygen.
The catalyst in this reaction is chlorine because it undergoes changes as the process continues while ozone is removed in the process. In the presence of sunlight, atomic oxygen is formed.
