Fungi, actinomycetes, lichens, earthworms and plants are the bioindicators of body of water or an ecosystem.
What can Bioindicators tell us about an ecosystem?Use of ecosystem or water bioindicators yields the following image.
Bioindicators are used to evaluate the state of the environment and how it changes over time. They include biological processes, species, or communities.
Lichens are one type of bioindicator. These plants are extremely vulnerable to airborne since they grow on surfaces like dirt, rocks, and trees. This is so that they may get the majority of their nutrition from the air.
The quantity and variety of lichens on the trees in our forests are indicators of how clean the air is. Because different lichen species are more or less susceptible to air pollution, knowing which species are present can also give us an idea of the pollution level.

Which of these levels of biological organization contains the other three?
A. Individual
B. Organ
C. Population
D. Organ system
A population contains other three. An organ forms an organ system the system forms an individual and many individuals forms population
Why is population a crucial issue?Population refers to all of the people who are present in a location at any given time. The population should be balanced with available means and resources because it is one of the key elements in maintaining environmental harmony.
A population is a subset of one species' members that lives in a certain area and, in sexually reproducing species, breeds with other individuals of the same species. For certain species, it is simple to define a population's geographic borders; for other species, it might be more challenging.

If a forecast states that the dew point and air temperatures are equal, what is likely to happen?
If a forecast states that the dew point and air temperatures are equal, the air is said to be saturated.
What is dew point?The dew point is the temperature to which a parcel of moist air must be cooled at constant atmospheric pressure and constant water vapor content in order for saturation to occur.
The dew point can also said to be the temperature at which the actual pressure of the vapor contained in an air parcel equals the saturation pressure, under constant atmospheric pressure.
When the dew point is equals the air temperature, the air is saturated and the relative humidity is %100.

False statements regarding a bacterium that is R+ is F+.
Everywhere you look, you can find bacterium (plural: bacterium), which are typically free-living organisms made up of just one biological cell. They make up a sizable group of prokaryotic bacteria. Bacteria, which are among the earliest life forms to exist on Earth and are typically a few micrometers in length, are found in most of its environments. The deep biosphere of the Earth's crust, acidic hot springs, radioactive waste, and soil all support bacterial life. By recycling nutrients, such as fixing nitrogen from the atmosphere, bacteria play an important role in many stages of the nutrition cycle. The decomposition of dead bodies is a part of the nutrition cycle, and the putrefaction stage is brought on by bacteria. Extremophile bacteria offer the nutrients required to maintain life in the biological communities surrounding hydrothermal vents and cold seeps.

Explain what happens as your cell needs to divide. Include why your cell is dividing and the process of division
Answer:
Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell
Explanation:
Why Cells Divide• Mitosis - the process your body cells use to make exact replicas of themselves.
• Meiosis - creates sperm or egg cells.
• Binary fission - how single-celled organisms like bacteria copy themselves
Scientific researchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. At this time it became the general view that viruses were biologically "alive." This changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. When not in contact with a host, the virus remains dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. In this state viruses can remain for extended periods of time, waiting to come into contact with the appropriate host. When in contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.

Extended infections are possible due to the fact trypanosomes undergo antigenic version—the expression of a large repertoire of antigenically wonderful floor coats, which lets the parasite populace steer clear of antibody-mediated removal.
3 categories of illnesses Trypanosoma causes are:
brucei, which causes drowsing sickness in human beings, and nagana in livestock. T. cruzi, which causes Chagas disorder in human beings. Trypanosoma culicavium, which infects birds and mosquitoes.The disease is more often than not transmitted via the chunk of an inflamed tsetse fly however there are other methods in which people are inflamed: mom-to-infant contamination: the trypanosome can move the placenta and infect the fetus.
Fever, extreme complications, irritability, intense fatigue, swollen lymph nodes, and aching muscles and joints are not unusual signs of sleeping sickness. some people expand pores and skin rash. innovative confusion, persona adjustments, and different neurologic issues occur after the infection has invaded the primary nervous gadget.
Antitrypanosomal treatment is indicated for all persons recognized with African trypanosomiasis. choice of therapy relies upon the infecting subspecies of the parasite and at the disease level. the primary-line drugs for both first and 2nd-stage disorders are extraordinarily powerful.

When the Carbon dioxide changes its state from gas to solid directly that is called dry ice.
How might dry ice be used for cleaning?Similar to sand blasting, dry ice cleaning, commonly referred to as cryogenic cleaning, uses solid CO2 or dry ice pellets instead of sand. The pellets expand by a factor of 700 when they hit the ground and evaporate into carbon dioxide gas. This expansion causes the contaminant to be raised and separated from the basic substance. creates daily dry ice blasting tools and exports them to numerous nations across the world.
In order to create dry ice, gaseous CO2 is first compressed and rapidly cooled to create liquid CO2. The liquid is next allowed to expand at a lower pressure to create CO2 snow. Finally, a hydraulic press compresses this snow into usable Dry Ice blocks, slices, or pellets.
