Answer: ENDOGENOUS
Explanation: Receptors readily binds with biochemical messangers (called ligand) in the body system.
A particular receptor will only bind with a specific ligand, which translates that a specific receptors which readily binds with opiate drugs (such as morphine and oxycodone) for reducing body response to pain, must have been in the past, had an interaction with an endogenous biomolecule similar in molecular composition with that of opioid pain relievers .
Which things need to be present for natural selection to take place? (select all that apply)
A.Variation in the population.
B.The ability for asexual reproduction.
C. Competition between organisms.
D. Large amounts of resources.
Answer:
A & C
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
YES - A) You must have variation in the population, typically in the terms of "fitness" or having admirable/sucessful traits that make them more likely to reproduce and ensure their own offspring are fit too.
NO - B) It is sexual (not asexual) reproduction that uses natural selection for their offspring. Although some asexual organisms use natural selection, it is ALWAYS used if possible with natural selection to ensure the fitness of characteristics is passed down.
YES - C) Competition is necessary for natural selection to occur. When those who are more physically fit compete, they are more likely to live against their opponent and therefore pass on the trait of fitness.
NO - D) Although resources are necessary, large amounts are not as it does not lead to fighting over them (scarcity) bringing us back to the need for competition above.

Which statements help explain how Earth formed as part of the solar system? Select the two correct answers. (1 point)
-The denser rocky material in the solar nebula stayed closer to the sun.
-Gaseous planets slowly changed to rocky planets after colliding with meteorites.
-Water and ammonia condensed from gases to ice particles.
-Very large asteroids broke apart to form rocky planets, including Earth.
-The accretion of cosmic dust formed the seeds of planets, including Earth
The statements 'the accretion of cosmic dust formed the seeds of planets' and 'the denser rocky material in the solar nebula stayed closer to the sun' help explain how Earth formed. It is part of the solar system.

it is estimated that you loose heat to cold water four times faster than to cold air. Your body is mostly water. What if your body had much less water in it, and the rest of it consisted of substances that heated and cooled as easily as metal. would a cold environment be more chilling or not?
Explanation:
Before explaining the following phenomenon, it is good to clarify one thing: the laws of thermodynamics are fulfilled and cold water usually freezes faster than hot water. However, and although it seems counterintuitive, it has been observed for centuries that this fact is not always fulfilled and under certain circumstances, hot water freezes before cold water. Aristotle was the first to record this phenomenon, but it was not published as a scientific observation until 1969 by Erasto Mpemba. Precisely due to the surname of the scientist born in British Tanganyika, this phenomenon is known as the Mpemba effect. A curious effect that has recently been having an impact due to a new viral called "boiling water challenge" and consists of throwing boiling water into the air to see how it quickly freezes and turns into snow.
Cold environment would be more chilling.
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide.What is homeostasis?Homeostasis is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.To know more about homeostasis here

Glycans are a virulence factor for which group of organisms?
A. fungi
B. viruses
C. bacteria
D. protozoa
E. helminths
Answer:
C.bacteriaExplanation:
because bacterial glycans are attractive pathogen-specific targets. Bacterial cells are coated with an impressive array of glycan structures that comprise their cell wall
Glycans are a virulence factor for bacteria. So, the correct option is C.
What are Glycans?
Glycans are also known as polysaccharides, are carbohydrate-based polymers made by all living organisms. They are basically chain-like structures that are composed of single sugar molecules (monosaccharides) linked together by chemical bonds.
Now, out of given organisms, only bacterial cell walls are mainly composed of polysaccharides. So, these glycans sites are target sites for disease-causing agents to perform their activity.
Therefore, glycans are a virulence factor for bacteria.

Which is one reason for the formation of global winds? (1 point)
-uneven heating of Earth's surface
-fewer daylight hours in Arctic regions
-loss of energy as warm air rises
-condensing of moisture in cooling air
One reason for the formation of global winds is the uneven heating of the Earth's surface.
The uneven heating of the Earth's surface is primarily caused by variations in solar radiation received at different latitudes.
The equator receives more direct sunlight when the sun's rays strike the Earth's surface, they heat the air in contact with it. n the poles, resulting in a temperature gradient across the planet. This temperature gradient drives the formation of global winds.
Fewer daylight hours in Arctic regions: This option is incorrect. The number of daylight hours in a region does not directly contribute to the formation of global winds. While sunlight does play a role in heating the Earth's surface and driving atmospheric circulation, the length of daylight hours is not a determining factor.
Loss of energy as warm air rises: This option is valid. As warm air rises due to heating from the Earth's surface, it expands and cools. This cooling causes the air to lose energy, and as a result, it becomes denser and sinks back toward the surface. This sinking motion creates regions of high pressure, which contribute to the formation of global winds.
Condensing of moisture in cooling air: This option is incorrect. The condensation of moisture in cooling air relates to the formation of clouds and precipitation, but it does not directly influence the formation of global winds.
Therefore, the uneven heating of the Earth's surface, due to variations in solar radiation, is a significant reason for the formation of global winds.
