a. Molecule X and Molecule Y are both carbohydrates.
b. Molecule X is a nucleic acid, and Molecule Y is a carbohydrate.
c. Molecule X and Molecule Y are both nucleic acids.
d. Molecule X is a carbohydrate, and Molecule Y is a nucleic acid.
Answers
The following which best describes these biomolecules is that Molecule X is a carbohydrate, and Molecule Y is a nucleic acid and is therefore denoted as option D.
What is a Biomolecule?They are referred to as organic substances and are usually made from cells and living organisms. Examples include carbohydrate, nucleic acid etc.
Molecule X is referred to as a carbohydrate because it contains an aldehyde group and also elements such as carbon, hydrogen and oxygen while nucleic acids contain base pairs and a deoxyribose sugar as shown in the diagram below.
This is therefore the reason why option D was chosen as the most appropriate choice.

Which organism from kingdom protista is most closely related to animals?
a) paramecium spp.
b) choanoflagellates diatoms
c) red algae
d) amoeba spp.
Answers
Choanoflagellates diatoms from kingdom Protista is most closely related to animals.
The choanoflagellates are a class of unicellular and colonial flagellate eukaryotes that live in free-living environments and are thought to be the closest living relatives of animals. Choanoflagellates are collared flagellates; at the base of each flagellum, they have a funnel-shaped collar of intertwined microvilli.The Choanoflagellates are not a varied group of protists, with only 150 species in total. The name "collar-flagellates" comes from the ring of densely grouped microvilli, or thin fingerlike projections, that surrounds the single flagellum by which choanoflagellates both move and take in food. They are tiny single-celled protists that can be found in both freshwater and ocean environments. The collar appears as a single transparent unit in light microscopy because the microvilli are so closely packed, as shown in these illustrations.Therefore, option (b) is correct.

When a big fish swims into an oncoming smaller fish and swallows it, the momentum of the two-fish system _______.
Answers
When a big fish swims into an oncoming smaller fish and swallows it, the momentum of the two-fish system remains the same.
In this case, the Law of conservation of momentum principle is used as when a big fish swims into a smaller fish and also swallows it, then there will be no change in the system as the momentum of the two-fish system remains the same.
But when the momentum of the big fish exists in the same condition but since the final momentum is to be true, there arises a combined mass of the big fish as well as the small fish, whereas the case of speed must be reduced.
The Law of conservation of momentum is important as it states that the total momentum that occurred in the initial state of the system remains the same as the momentum that exists in the final state of the system. This conservation principle helps to determine the initial and final velocity of a system that undergoes collision. This collision can be either elastic or inelastic. According to this theory, the momentum of the two fish systems remains here.

Salt Lake City seems to be in a distinct state than southern Utah and the majority of the area east of the Wasatch.
In the vicinity of Salt Lake, several quite different geological regions are combined, so if you drive a few hours in any direction, you'll be in a very different region. For instance, if you travel east to Vernal, you'll think you're in a St. George suburb in the far southwest of the state. Even though St. George is over two hours away from Las Vegas, it is essentially a satellite of that city. It is located in a stunning red rock region with fields of black lava stone surrounding dormant volcanoes, canyons, arches, and palm trees. Geologically speaking, rather than merely politically, it seems like another planet. Culturally, anyone from Utah will feel at home in St. George, if they can endure the heat. It is still a very LDS town, but it is still managed by a small group of old-guard families who came here at Brigham Young's request nearly fifty years ago.

Approximately how many atoms thick is a cell membrane, assuming all atoms there average about twice the size of a hydrogen atom?.
Answers
There are around 50 atoms in the cell membrane.
Knowing that the thickness of a cell membrane is somewhere between 7.5 and 10 nm will allow you to divide 7.5 and 10 by 0.2 nm, where 1 nm equals 1*109 m.
The cell membrane is roughly 37.5 and 50 atoms thick, according to the two answers of 47.5 and 50.
A hydrogen has a diameter of 10^ -10 m. A cell membrane has a 10^8 m thickness.
The formulae of thickness in terms of number of atoms = d /2 × D
Here the (d) = the diameter of membrane
The (D) = The diameter of hydrogen atom
The diameter of hydrogen atom = 10^-10 m
The thickness of membrane = 10^8 m
by substituting these value in above formulae
The number of atoms = 10^8 /2 × 10 ^−10 m
= 50 atoms
Consequently, the thickness of a cell membrane is equivalent to 50 atoms' total thickness.

Vasoconstriction is caused by ______ stimulation of vascular smooth muscle and ______ stimulation of vascular smooth muscle causes vasodilation.
Answers
Vasoconstriction is caused by sympathetic stimulation of vascular smooth muscle and parasympathetic stimulation of vascular smooth muscle causes vasodilation.
The narrowing (constriction) of blood arteries by tiny muscles in their walls is known as vasoconstriction. Blood flow is delayed or halted as blood vessels close. Vasoconstriction can range from mild to severe. It might be brought on by a sickness, medication, or psychological issues.Norepinephrine's interaction with postsynaptic -adrenergic receptors is the main mechanism by which sympathetic innervation of the peripheral vasculature promotes vasoconstriction. The majority of the body's blood arteries lack parasympathetic innervation. However, salivary glands, gastrointestinal glands, and vaginal erectile tissue are all innervated by parasympathetic neurons, which results in vasodilation. The parasympathetic division causes the body to go into "rest or digest" mode, typically lowering blood pressure and heart rate.Blood arteries often expand in response to parasympathetic stimulation, increasing blood flow but decreasing pressure.learn more about Vasoconstriction here: https://brainly.com/question/4359984

How does water having high specific heat capacity and high heat of vaporization help life on earth?.
Answers
Having high specific heat capacity and high heat of vaporization helps to sustain life on Earth as heat is absorbed by the water and released slowly, which helps to sustain life.
Water has a specific heat of vaporization. Around 40,000 Joules of energy are required for vaporizing one mole of water. It is due to this heat of vaporization, that water has the ability to store excess heat and release it slowly. Such an effect causes the Earth to tolerate the temperature changes caused by heat from the Sun.
The high specific heat capacity of water helps life on Earth by maintaining ocean temperatures so that aquatic life can survive. As a major part of the Earth is water, hence the specific heat capacity of water absorbs sunlight hence protecting the Earth from high-temperature changes.
