Explanation:
in q 1, part a, we need to tell what we observed in the growth of plants. we observed that the plant h was groing faster and healthier that plant g due to the fact that it was provided with a nutritive solution.
in its part b, we write the conclusion, i.e the plant which was provided with a nutritive solution grew more as all minerals required by the plants were replenished properly.
In q2, part a, we just compare their physical properties such as the plant g was not as healthy as plant h and plant h grew faster and taller than plant g.
in q2, part b, we just write what the solution is supplying the plant with, you can also check each one of their speciality on the web and write it also.

how does a cell get energy from an atp molecule
Answers
Answer:
Whenever a cell needs energy, it breaks the beta-gamma phosphate bond to create adenosine diphosphate (ADP) and a free phosphate molecule. Cells get energy in the form of ATP through a process called respiration, a series of chemical reactions oxidizing six-carbon glucose to form carbon dioxide.

as of may 2020, carbon dioxide levels have reached 417 parts per million. what level should they be at to have the world in a climate similar to that in which civilization first developed?
Answers
Given what we know about global carbon levels in the present and the past, we can confirm that in order to be at the level of early civilizations, the modern-day carbon level should be at 280 parts per million.
Global atmospheric carbon levels are measured in parts per million. What this means is that for every one million units of mass in the atmosphere, 280 of them were carbon. This means that in recent years, the global carbon levels in the atmosphere have doubled.
The primary cause of these increased carbon levels is industrial pollution. Chemicals are released into the atmosphere as a by-product of industrial processess. This began with a noticeable spike during the industrial revolution and has then increased without end.

In addition to the frog, the other organisms that are classified as modern amphibians are toads and salamanders. Therefore, the correct option is A.
What are modern amphibians?Modern amphibians are a class of cold-blooded vertebrates that spend part of their life cycle in water and part on land. They are united under the taxon Lissamphibia. They are divided into three clades which are Urodela, Anura and Apoda. In addition to frogs, the other two groups of modern amphibians are toads and salamanders.
Snakes and lizards are reptiles, which are a different class of cold-blooded vertebrates. Opossums and koalas are marsupials, which are warm-blooded mammals, and sharks and skates are fish, which are cold-blooded vertebrates but are not classified as amphibians. Therefore, the correct option is A.

how do mitochondria generate and store the energy used to produce most of the atp made during aerobic respiration
Answers
By generating a ionic (electrochemical) gradient
Answer:
The citric acid or Krebs cycle processes in the matrix of mitochondria produce a molecule called NADH. NADH is then converted to adenosine triphosphate by enzymes buried in the mitochondrial inner membrane (ATP). Energy is stored in the form of chemical bonds in ATP.
Explanation:
During aerobic respiration, how is ATP created in the mitochondria?Oxidative phosphorylation produces the majority of the ATP produced by aerobic cellular respiration. By pumping protons across a membrane, the energy released by the O2 is utilized to create a chemiosmotic potential. This potential is subsequently used to activate ATP synthase, which converts ADP and phosphate groups into ATP.
What is the mechanism by which mitochondria store energy?Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a tiny molecule that stores chemical energy created by mitochondria (ATP).
What is ATP's energy storage mechanism?The energy currency of the cell is ATP, or adenosine triphosphate. It retains the energy created during cellular respiration when glucose is oxidized. Energy is stored in the form of high-energy phosphate bonds, which are broken to release energy. Energy is released when ATP is broken down into ADP and Pi.

if the carrying capacity for the north atlantic cod on the grand banks of newfoundland is 500,000 tons, when do you expect that the rate of population growth would be greatest?
Answers
If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, then we would expect that when there are 250,000 tons of cod on the grand banks, the population growth will be greatest.
The carrying capacity speaks volumes about the maximum amount of a species population that the ecosystem can sustain permanently provided there is the availability of water, food, habitat, and other life essentials.
In terms of population ecology, it is defined as the maximum burden that the environment can tolerate.
In population ecology, populations normally decrease above the carrying capacity while they increase below the carrying capacity. A decline in population size above the carrying capacity can be caused by a variety of factors, such as a lack of sunshine, space, or food availability.
Therefore, we can conclude that If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, the rate of population increase will be maximum and greatest when there are 250,000 tons of cod on the Grand Banks.

why are antibiotics not effective against viruses?
Answers
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.
are there other tests that could be used to determine if cyclohexanol is present in your product? give at least one test with some detail of the expected result for the presence of cyclohexanol.
Answers
One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.
The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution. Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.
The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a positive result will look like the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.
