Among the given options, the following is not a description of an aorta: It is rarely vascularized.The aorta is the largest artery in the human body. The aorta is composed of smooth muscle and elastic fibers. The aorta originates from the left ventricle, and it delivers oxygenated blood to all parts of the body.
Baroreceptors are present in the aortic arch. Baroreceptors are sensory receptors that detect changes in blood pressure.Baroreceptors are involved in the maintenance of blood pressure and homeostasis. The aorta contains baroreceptors that help regulate blood pressure by detecting changes in pressure in the aortic arch.
When the blood pressure decreases, the baroreceptors send a signal to the brain that stimulates the sympathetic nervous system to increase blood pressure. When the blood pressure increases, the baroreceptors send a signal to the brain that stimulates the parasympathetic nervous system to decrease blood pressure. Therefore, the correct answer is, "It is rarely vascularized."

Why is water so susceptible to pollution?
A) It occurs naturally as a solid, liquid, and gas
B) It can be found underground
C) It is a universal solvent
D) Only 3% of Earth's water is freshwater
Answer:
I believe its (A) hope that helps
Water so susceptible to pollution because it occurs naturally as a solid, liquid, and gas. Hence option A is correct.
What is pollution?Pollution is defined as the contamination of the land or soil that hinders the development of natural life. Sulfur dioxide and other hazardous gas emissions contribute to acid rain, global warming, and other factors that make it difficult for animals to thrive. These factors include rising temperatures, unpredictable rain patterns, and droughts.
The majority of the freshwater on the planet is inaccessible to humans. A little more than 69 percent of the freshwater on Earth is trapped in glaciers and polar ice caps as ice, and another 30 percent is present beneath the surface as groundwater.
Thus, water so susceptible to pollution because it occurs naturally as a solid, liquid, and gas. Hence option A is correct.

Who is susceptible to infectious diseases for which vaccinations are available?
a. anyone who is not vaccinated
b. very young or very old people
c. people in developing countries
d. people in developed countries
Answer:
Those most susceptible to infectious diseases and for whom vaccination is available are very young or very old people.
Explanation:
Infectious diseases tend to occur more frequently and relatively severely in the extreme age groups, i.e., in childhood and old age.
Although everyone is susceptible to acquiring an infectious disease, vaccines will always be available for very young and very old people, as they are considered to be at higher risk of infection.
Vaccines are preparations that contain fractions of microbes, without the capacity to produce disease, to stimulate the immune system, and to be able to fight the infections they produce.
With regard to the other options, which are not correct:
a. Anyone who is not vaccinated : anyone can be vaccinated, especially if they have not been vaccinated, but the most susceptible are given priority.
c and d. People in developing or developed countries must receive the vaccines established by their health system, always guaranteeing the immunization of the most susceptible.
Answer:

observed under a microscope. Three possible outcomes are diagrammed
below. Which of the following best predicts which diagrammed
microscope view the laboratory worker would see and best explains why?

View 2 because the RBCs use energy to allow sodium entry and to pump water out

Answer:
View 2
Explanation:
The rate of the water movement into the RBCs equals the rate of water movement out of the cells <3
The statement that best predicts diagrammed microscope view the laboratory worker would see is View 2. This is because the rate of water movement into the RBCs equals the rate of water movement out of the cells.
What is Microscope?A microscope may be defined as a type of laboratory instrument which is utilized to examine objects that are too small to be visualized by the unaided eye.
According to the context of this question, if a sample of human blood was functionally placed in a test tube containing a physiological saline solution.
This means that a concentration of salt is present in it. Due to this, the rate of migration of water into the RBCs is equal to the rate of water migration outside the cell. This is because the conditions are ideal for RBCs with respect to a specific cell.
Therefore, the correct option for this question is C.

Why is it important to know how much light can penetrate different sections of an aquatic biome?
Answer:
The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems. At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic, lacking sufficient light for photosynthesis.
Further info...
Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air, however. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (like fog, dust, or insect swarms), usually these are not permanent features of the environment. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems. In freshwater systems, stratification due to differences in density is perhaps the most critical abiotic factor and is related to the energy aspects of light. The thermal properties of water (rates of heating and cooling) are significant to the function of marine systems and have major impacts on global climate and weather patterns. Marine systems are also influenced by large-scale physical water movements, such as currents; these are less important in most freshwater lakes.
The ocean is categorized by several areas or zones. All of the ocean’s open water is referred to as the pelagic realm (or zone). The benthic realm (or zone) extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis. The deepest part of the ocean, the Challenger Deep (in the Mariana Trench, located in the western Pacific Ocean), is about 11,000 m (about 6.8 mi) deep. To give some perspective on the depth of this trench, the ocean is, on average, 4267 m or 14,000 ft deep. These realms and zones are relevant to freshwater lakes as well.

What are two ways that Nitrogen can get "fixed" to be used by plants
Answer:Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria. (Learn more about this process in the article The role of clover.)
Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
Industrially: People have learned how to convert nitrogen gas to ammonia (NH3-) and nitrogen-rich fertilisers to supplement the amount of nitrogen fixed naturally
