Hope it is helpful....Nucleic acids are composed of:
a: a phosphate group, a pentose sugar, a nitrogen base
b: a phosphate group, a pentose sugar, a carboxylic acid
c: a pentose sugar, a nitrogen base, an R group
d: a nitrogen base, an amino acid group, a carboxylic acid
Answer:
a phosphate group, a pentose sugar, a nitrogen base
Explanation:
nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.

what are the effects of the even on each of the Earth's four spheres?
Answer:
An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction.
what macromolecules are found in a hot dog ?
Answer:
contain nitrites and/or nitrates
Explanation:
The meat is comprised of beef, pork, or turkey, which are all forms of protein (again, amino acid polymers). There is also a fair amount of fat (animal fat tends to be in the form of triglycerides) and some degraded genetic material from the original organism now being turned into food. :) In addition to these things, the hot dog may contain some food coloring and will likely contain some preservatives - a common preservative for meats (to prevent botulism and rancidity) is sodium nitrite
What is the process of nitrification?
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Fungi convert nitrogen in dead plants into ammonium, which converts proteins into ammonia.
Nitrogen is converted into a useable form through lightning fixation.
Plant enzymes reduce nitrogen compounds into amino acids.
Answer:
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.

do fertilizer also increase the number of bacteria as they do for plants, or do they increase when the decomposition of plants occur?
Answer:
my views
Explanation:
bacteria helps in the decomposition of wastes ,and after the decomposition of waste material by bacteria it leads to the creation of nitrogen's oxides and this nitrogen's oxides works as fertilizer which leads to the good crops and we don't need of any chemicals' made fertilizer
Answer:
Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems.

explain movement in fern
Answer:
One of the most typical ways that plants like ferns move is through a process known as phototropism. Essentially, they move and grow towards light .Plants may also move or grow in response to other stimuli, in addition to light. They can grow or move in response to physical touch, in response to a chemical, or toward warmth

RNA differs from DNA in the type of a) purines & pyrimidness b) sugars & Purmes c) sugar & pyrimidness. dl pyrimidness (please give right answer only)
Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Explanation:
Describe the general temperature of ocean currents near the equator and the poles.
Answer:
Currents flowing away from the Equator are generally warm.
Explanation:
That is because the Equatorial regions is the source of warm air and water. Ocean currents flowing from the Equator thus carry this warm water with them. The most prominent example is the Gulf Stream in the Atlantic Ocean, which runs most of the way to the North Pole and brings mild winter climates in its wake to adjacent coastal areas. In the Pacific Ocean the Alaska Current likewise carries warm water northward making Anchorage, Alaska much milder in winter than inland areas with the same latitude.

The blood pressure of a person is 140/100 mm of Hg, what does it mean?
Answer: When is blood pressure considered high? Normal blood pressure is under 120/80. From 120/80 to 139/89 is pre-hypertension. The threshold for high blood pressure is 140/90, while anything over 180/110 is hypertensive crisis – an emergency.

Use the image below to answer the question.
The illustration shows the mitochondrial intermembrane space. Molecules enter and exit enzymes. Molecule upper N upper A upper D upper H passes through enzyme upper N upper A upper D upper H Reductase releasing upper H superscript + baseline and upper N upper A upper D superscript + baseline. A blue arrow starts at upper N upper A upper D superscript + and goes through enzyme Ubiquinone then enzyme Cytochrome Reductase, an upper H superscript + baseline is released. The arrow continues through enzyme Cytochrome c and enzyme Cytochrome Oxydase, another upper H superscript + baseline is released. The formula 2 upper H + one-half upper O subscript 2 baseline is to the left of enzyme Cytochrome oxydase with an arrow pointing to the other side. The arrow meets with the arrow from upper N upper A upper D superscript + baseline at upper H subscript 2 baseline upper O. To the right is upper A upper T upper P synthase, upper A upper D upper P + upper P subscript 1 baseline have an arrow going under upper A upper T upper P synthase, an upper H superscript + baseline arrow points to the arrow, the result is upper A upper T upper P.
Which step of cellular respiration is shown in the image?
glycolysis
lactic acid fermentation
electron transport chain
Krebs cycle
Answer:
electron transport chain
Explanation:
just took the quiz
The image shows the C. electron transport chain (ETC) step of cellular respiration
What is the electron transport chain ?The ETC is the final stage of cellular respiration, where oxygen is used to create ATP. NADH and FADH2, which are produced in the Krebs cycle, donate electrons to the ETC.
The electrons are passed through a series of proteins, which release energy that is used to pump protons across the mitochondrial membrane. This creates a proton gradient, which is used to power ATP synthase to produce ATP
The Krebs cycle and lactic acid fermentation are both earlier steps in cellular respiration. In the Krebs cycle, pyruvate is oxidized to produce NADH, FADH2, and ATP. In lactic acid fermentation, pyruvate is converted to lactate, producing NADH.

How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
How will a solution change if a base is added?
The hydroxide ion concentration will decrease and lower the pH.
The hydroxide ion concentration will decrease and raise the pH.
The hydrogen ion concentration will increase and lower the pH.
The hydroxide ion concentration will increase and raise the pH.
Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.
