Answer:
it's water molecules
Explanation:
Polar bonds are intermediate between pure covalent bonds and ionic bonds. They form when the electronegativity difference between the anion and cation is between 0.4 and 1.7. Examples of molecules with polar bonds include water, hydrogen fluoride, sulfur dioxide, and ammonia
Because of its ability to decompose into oxygen and water, hydrogen peroxide is very useful against what group of organisms
Answer:
Hydrogen peroxide works by producing free radicals that damage cellular macromolecules. Hydrogen peroxide has broad-spectrum activity, working against gram-positive and gram-negative bacteria (with slightly greater efficacy against gram-positive bacteria), fungi, viruses, and endospores.

Answer:
Carbon dioxide (CO2) dissolves in the ocean and reacts with water to form carbonic acid—which in turn generates bicarbonate, carbonate, and hydrogen ions. Calcium and carbonate ions combine to form the solid calcium carbonate crystals in their shells and skeletons.

why are antibiotics not effective against viruses?
Answer:
Viruses are different to bacteria; they have a different structure and a different way of surviving. Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

Scientists find cell with a genetic mutation in the cyclin dependant kinase gene. The mutation leads to a misshapen CDK molecule that will not bind to cyclin molecules. How would this impact the cell cycle of that cell
Answer:
The mutation leads to a misshapen CDK molecule that will not bind to cyclin molecules. How will this impact the resulting daughter cell? Explain. If cyclin molecules did not bind to CDK, the cell could not progress through the cell cycle.

As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

Give TWO reasons why mechanical digestion of food is important! Marking brainliest
Answer:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.Explanation:

Explain how a wholemeal sandwich with tuna and tomatoes will be broken down by the digestive system. Start the process from the mouth and end at the anus.
Answer:
All of our energy and nutrition come by way of the gastrointestinal (GI) tract. It is an amazing machine well designed for digesting and absorbing nutrients and for shielding the rest of the body from microorganisms, viruses and other foreign matter. The GI tract spans from the mouth to the anus, with each separate organ having a role in digestion, absorption or excretion.Lastly, if you would like to learn more about yourself and how you can best reach your own nutritional and fitness goals, we encourage you to take a look at the following home health testing guides and resources:

Explanation:
Estimating the weight of a dinosaur using only bones is difficult. Another way is by using scale models. The density of a dinosaur is scaled based on the average density of what living animal
Given what we know about the methods used by scientists to estimate the weight of a dinosaur, we can confirm that the density of a dinosaur is scaled based on the average density of the common crocodile.
Scaling the density of an extinct animal based solely on bones can be a daunting task. Since the bones themselves do not offer much information on which to base such a calculation, scientists are often forced to rely on other estimations. One such example is the bone scaling method.
This method relies on the genetic relationships shared between the dinosaur and current-day living animals. This offers the ability to compare the dinosaur to the known body mass of a modern-day living animal. The animal most commonly used is the crocodile, however, though this method can provide the scientists with a degree of accuracy, it lacks precision.

The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?
Answer:
2
Explanation:
The enzyme will be the most effective between 8 and 10
The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.
What are enzymes?Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.
Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.
From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.
Therefore, the correct option is 2.

List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.
