Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
Explanation:
I chose this because it seems like the most logical explanation.
"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.
What is biodiversity?Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.
The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.
In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is, ecosystem X has a greater amount of biodiversity. So, during the drought, the bison in ecosystem X are better able to survive.
Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

Explanation:
Pulmonary arteries transport ________.
A) oxygenated blood to the lungs
B) blood rich in carbon dioxide to the lungs
C) oxygenated blood to the heart
D) oxygenated blood directly to the aorta
No links or I'll report
Answer:
B
Explanation:
I would say this because the pulmonary circulation only transports deoxygenated blood. And this blood gets transported to the lungs so the lungs can absorb oxygen and release carbon dioxide. I am not sure about this one though. This is what I think.
Pulmonary arteries transport blood rich in carbon dioxide to the lungs also known as deoxygenated blood.
Blood Transportation:Arteries carry oxygenated blood in the body, and the pulmonary arteries carry deoxygenated blood to the lungs.The main pulmonary artery, or the pulmonary trunk, transports deoxygenated blood from the heart to the lungs.The main pulmonary artery branches into both a right and left vessel. The right pulmonary artery carries blood to the right lung. The left pulmonary artery carries it to the left lung.Thus, we can conclude that Pulmonary arteries transport deoxygenated blood from the heart to the lungs.

A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27 degrees celeius. What gas is being made?
Answer:
Oxygen
Explanation:
Plants in the presence of sunlight (a major requirement) are capable of manufacturing their own food via the process of PHOTOSYNTHESIS. Photosynthesis combines carbon dioxide (from atmosphere) and water (from soil) to produce glucose (carbohydrate) and oxygen gas (as a waste product). The equation as follows:
6CO2 + 6H2O ➡ C6H12O6 + 602
According to this question, a student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The process carried out by the plant exposed to the bright light is PHOTOSYNTHESIS, hence, the gas given off is OXYGEN.

Which of the following is NOT true of a reaction that breaks a bond?
A. It creates low-energy products
B. It is what happens in cellular respiration
C. It is an endergonic reaction
Answer:
C
Explanation:
Endergonic reactions use energy to build bonds
Exergonic reactions release energy through breaking bonds
C. It is an endergonic reaction.
Endergonic v/s Exergonic:
In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill) while In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill). Endergonic reactions use energy to build bonds while Exergonic reactions release energy through breaking bonds.When a bond breaks, it creates low-energy products.In cellular respiration, breaking of bond happens.Therefore, the statement which is NOT true for a reaction that breaks a bond is option C.

The larvae of potato beetles cover themselves in their own feces to avoid being consumed by predators. What system produces feces?
Answer:
Explanation below
Explanation:
Hemisphaerota cyanea, also known as the palmetto tortoise beetle, is a type of leaf beetle that cover themselves with their own feces, just to persuade most predators to pass them by. This form of outrageous defense, developed by the crafty beetle, was discovered by biologists at the Cornel university.
The feces comes out of the hindgut of the beetle, fashioned like golden strands, which can be used to protect the vulnerable body of the beetle.

Answer:
Mannitol is a drug that temporarily disrupts tight junctions. This drug is often added to medications that need to get into the extra-cellular fluid of the brain because it will make the capillaries of the blood-brain barrier more permeable to larger molecules.
Explanation:
The blood-brain barrier's components are endothelial cells, basement membrane, pericytes, and astrocyte endfeet. The gaps between endothelial cells are small. As a consequence, they form tight junctions that allow the passage of specific and small molecules. In this way, the barrier stops any pathogen from entering the brain. That is to say, that the blood-brain barrier is extremely selective; therefore, medications will not pass through it, so to allow the medicine to enter the brain extracellular fluid, the tight junctions of the endothelial tissue must be disrupted with mannitol.

Why does the earth have a magnetic field?
Answer:
QUESTION:
Why does the earth have a magnetic field?
ANSWER:
The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. The powerful magnetic field passes out through the core of the earth, passes through the crust, and enters space.
