5. One of the most important steps to achieve a more sustainable future is to reduce a. Water conservation b. Overconsumption c. Population growth d. Both B and C
Answer:
B.
*Read the explanation plz
Explanation:
A actually increases sutainability, and C is just wrong. It's technically saying that we should not let humans be born, we shouldn't let people get pregnant, which of course no one is gonna listen to. So B is right because if we consume too many things, the next generation won't have as many resources as they need to survive.
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.

adaptive features of Earthworm
here's your answer..
The adaptive features of Earthworm include streamlined body with no antennae or arms. The body of this organism is divided into segments.
What are the adaptive features?Adaptation can be defined as a state of the physical or the behavioral characteristics of an organism which helps them to survive better in the surrounding environment. Adaptation is essential for the survival of organisms in the new environment. These adaptations help the characteristics to become a part of the genetic makeup of the organisms.
An earthworm is a streamlined body organism with no antennae or fins or any arms or legs. The streamlined shape of the body is an adaptation to living in the narrow burrows which are present underground and the need to move easily through the soil. An earthworm has circular muscles which surround each body segment in the organism.

#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.

A. Overlying, adjacent plates collide violently.
B.groundwater rises to the surface.
C.new crust is formed along the boundary.
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.
