Throughout the day, activities in the liver, kidneys, and endocrine glands undergo large changes. Body temperature, blood pressure, and amino acid levels also shift from hour to hour. In fact, people tend to be more energetic and alert when these and other activities are at their highest point once a day. This is a description of Group of answer choices
Answer:
Circadian rhythms.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.
Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.
Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

why do prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years
Prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years for the following reasons:
The prevailing winds in the region are generally from the southwest.The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. In the case of Christchurch, there are a few reasons why warm ocean currents tend to pass by the region in normal years:Warm ocean currents are typically driven by prevailing winds, oceanic currents, and other factors such as the shape of coastlines and the positions of islands.
The prevailing winds in the region are generally from the southwest. These winds blow parallel to the coastline, which means that warm ocean currents are deflected away from the shore and towards the east. As a result, the waters off the coast of Christchurch are generally cooler than those further north or northeast. The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. These islands help to direct the flow of warm water towards the Coral Sea and the Tasman Sea, rather than towards the coast of New Zealand. This means that Christchurch, which is located on the eastern coast of the South Island, is less likely to experience the effects of warm ocean currents.Note: That oceanic currents and winds can be affected by a range of factors, including El Niño and La Niña events, which can cause changes in sea surface temperatures and alter the path of ocean currents. As a result, there may be some years when warm ocean currents do reach Christchurch, even if this isn't typically the case in normal years.

A biology teacher takes fish, algae, pond weed, invertebrates, and bottom muck from a local pond and establishes them in an aquarium. When the system is stable, the teacher seals it into a large, airtight glass box and leaves the box in a sunny location. After three months, the organisms in the aquarium appear alive and healthy. Which of the following statements about the experiment is true?
a. During the three months, the biomass of animal life was greater than the biomass of plant life.
b. Some of the energy in the system has moved from one organism to another.
c. The air in the glass box contains no carbon dioxide.
d. No energy has entered or left the glass box.
Answer: B. Some of the energy in the system has moved from one organism to another during the three months.
Explanation:
Option A is incorrect as the biomass of plant life will be greater than that of animal life since plants are considered to be primary producers.
Option C is incorrect as the air in the glass box contains carbon dioxide which is necessary to synthesize glucose.
Option D is incorrect as energy has entered the glass box since it's in a sunny location which gives it energy from the sun.
The correct option is B "Some of the energy in the system has moved from one organism to another during the three months".

#Hope it helps!
Sucrose is not a simple sugar because it is made up of both glucose and fructose so sucrose is called a disaccharide. Therefore, option (D) is correct.
What is simple sugar?A monosaccharide, often known as a simple sugar, is a form of carbohydrate that cannot be broken down into smaller molecules of glucose and is thus readily absorbed by the body.
There are three primary kinds of simple sugars: glucose, fructose, and galactose. All of these sugars have the same chemical composition, but their structures are quite different from one another.
Sucrose on the other hand is a disaccharide composed of both glucose and fructose. Therefore, it is not a simple sugar and can be broken down into smaller or simpler molecules.

What determines whether a star will end its life cycle as a black hole or neutron star or as a white dwarf?
Answer:
Where a star ends up at the end of its life depends on the mass it was born with. Stars that have a lot of mass may end their lives as black holes or neutron stars. A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf.
The initial mass of the star with which it was born will determine how the star will end its life cycle.
What are black holes, neutron stars, and white dwarfs?
Black holes are regions in space with an extremely high pull of gravitational force which cannot even be escaped by light. Black holes are formed when the central core of a dying star collapses in itself.
Neutron stars on the other hand are extremely dense dead stars. Neutron stars are extremely bright objects, unlike black holes. Black holes are extremely dark because they trap any surrounding light while neutron stars emit light.
The massive stars in the universe end up as neutron stars or black holes. A star that has a low or medium mass ends up as a white dwarf.
A white dwarf is a dying star with a mass comparable to the mass of our sun but a size comparable to the size of the earth. Thus they have high mass and low dimensions.
Therefore, the factor that determines what a star will end up as is its mass when it was born.

D.oceanic plates slide beneath continental plates.
E.overlying, adjacent plates are pulled apart.
Overlying, adjacent plates are pulled apart when magma convection currents flow away from one another.
What is magma conventions?Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.Hence, option E is correct.
