Some ways to protect from the overexposure to the different kind of contaminants that surround us in this modern environment are:
• Try to consume the most organic and home-made food, avoiding ultra-processed and fast food.
,• Choose hygiene and cleaning products with the less amount of chemicals possible and use them in adequate amounts.
,• Use responsibly medicaments, especially antibiotics.
,• Avoid contaminated areas such us water, or regions very close to farms that are fumigated.
,• Use sunscreen and avoid solar exposure at the high risk hours.
Steps that should be taken to ensure that people are not overexposed to any harmful substances is to regulate by laws the allowed amouns of this substances in the products we consume, and near the places we live. An example of this is the maximum number of x-rays allowed per person a year due to radiation.

Explanation:
Interdependent relationships in biology are based on mutual dependence between organs and body systems. Most organs have a job (aside from the appendix and such) and they all work together to keep the body running. For example, the lungs introduce air into the bloodstream, but what would be the point if there was no heart to pump the blood? Your organs fully depend in eachother to be effective.
why were Democritus ideas rejected by other philoshers of his time
2,500 years ago, Democritus suggested that all matter in the universe was made up of tiny, indivisible, solid objects he called "atomos." However, other Greek philosophers disliked Democritus' "atomos" theory because they felt it was illogical.
What interesting new hypothesis is being studied regarding embryo self-inspection
early in development?
The hypothesis was regarding embryo self-inspection in early development is that viability of embryo metabolism is quite rather than active due to depletion and appearance of amino acids from culture medium.
Early embryo consist of remarkable plasticity which means ability of separated early blastomeres to produce a whole organism. This aspect was determined from flux of radiolabeled methionine, premises that extent of DNA damage, RNA and protein content of immature oocyte are key factors whether zygote progresses to blastocyst stage.
This hypothesis was obtained from human and mouse and could be equally applied to reproduction in livestock, to get models for humans.

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
What is the importance of chemiosmosis?
Answer:
Chemiosmosis is involved in the production of adenosine triphosphate (ATP), which is the main molecule used for energy by the cell.
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.

How is looking at the carbon footprint or water footprint similar to looking at a biomass, energy,
or numbers pyramid?
The way that looking at the carbon footprint or water footprint similar to looking at a biomass, energy, or numbers pyramid is that indicates how much energy is stored as new biomass at each trophic level, and a pyramid of biomass shows how much biomass is stored as new biomass overall.
What is the carbon footprint of biomass?Of all energy sources, biomass energy has the fourth-highest carbon footprint. On a life-cycle basis, biomass fuel emits 230 grams of carbon dioxide (CO2) for every kWh produced. It is not as advantageous as it might seem, it contributes to climate change, and has other detrimental environmental repercussions.
Therefore, note that at higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic level creatures is known as biomass.

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.

Active transport is the form of particle transport that requires input of energy from the cell.
Active transport is the one that makes use of energy for the transport of molecules across the membrane. It is further classified into two types: primary active transport and secondary active transport. Primary active transport directly uses the energy from ATP hydrolysis for the transport. Whereas, secondary transport involves cotransport system where the energy released from the downhill transport is used for the uphill transport of molecule.

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.

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.
