Answer:
Diagram, in attachments
Explanation:
From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules attached to it.
The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and Nitrogenous bases.This is the structure of nucleotides and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another nucleotide molecule it forms a nucleic acid molecule.
The second structure from left to right with long carbon chains, it is a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.
However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced one of the the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.
The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids and hyrdogen atom.In the above structure condensation reaction has occurred between the hydrogen atom of the amine group and carbonyl group of the other amino unit to form a dipeptide.The bond formed from the condensation is the peptide bond.
The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO -Carbonyl group and hydroxyl group are glues to this.
Laboratory helps you identify things rather than the others using controlled variables
Explanation:
1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.
2.
An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
3.Why Do We have Seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.
Why Do the Seasons Change on Earth?
Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.
The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.
Answer:
Night
Explanation:
Usually, a microfilariae blood test is conducted at night to coincide with the appearance of microfilariae.
Answer:
No.
Explanation:
Hepatitis C is the most common bloodborne pathogen.
Hepatitis C as of 2022 has a infection rate of 3.7 million.
Hepatitis B as of 2022 has a infection rate of 2.2 million, or <em>1.5 million</em> lower than Hepatitis C.
Therefore, Hepatitis B is not the most common bloodborne pathogen.
