What are two reasons the wolves may eat fish in autumn instead of deer or moose?
Wolves may resort to eating fish in autumn instead of deer or moose because the preys usually hibernate during this period.
What is hibernation?It is a period of inactivity brought about by unfavorable environmental conditions.
During autumn, larger prey animals such as deer or moose may become inactive. Thus, the food of wolves becomes limited. In addition, many trees whose fruits serve as food for wolves may not fruit in autumn.
Thus, wolves had limited options and may resort to eating fish in rivers.

How does heart failure affect the lungs?
Carbon dioxide enters the lungs.
Blood leaves the lungs.
Fluid can build up in the lungs.
Too much oxygen enters the lungs.
Answer:
A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.

When the adaptive feature is enhanced by female choice, it is referred to as of what?
Answer:
S3xual selection as a consequence of female choice is easy to understand, provided we are willing to accept that female preferences exist. If females show a preference, then males with the preferred trait will leave greater numbers of offspring, and their trait values will tend to increase in frequency in the population.
Explanation:
The more homologous structures two species have, the ________ closely related they may be.
Answer:
more closely
Explanation:
The more alike the structures are the more closely related the organisms are to one another.
The more homologous structures two species have, the more closely related they may be, as homologous structures are traits or anatomical features that are similar in different species.
Homologous structures are features that are similar in different organisms because they are inherited from a common ancestor. These features may have different functions in each organism, but they share a similar underlying structure. For example, the bones in the wings of a bird, the arms of a human, and the flippers of a dolphin are all homologous structures, despite having different functions and appearances. The degree of similarity of homologous structures can be used as an indicator of how closely related two species are to each other.

How do Earth’s spheres interact?
Answer:
The Geosphere
Geosphere includes all the elements that form the crust and core of the Earth. Rocks and sand particles ranging from drylands to those found at the bottom of the ocean are examples of the geosphere. Examples also involve minerals, lava, molten magma and mountains. The geosphere undergoes constant processes that modify other spheres. One of the examples is the rock cycle.
Rock Cycle
An illustration of the rock cycle
In this cycle, the melted rock from below the Earth’s crust is blown out to the surface through vents as lava. Hardened lava, together with rock materials, is weathered and eroded from earth movements. The eroded particles end up somewhere and build up. After many years of buildup, the pressure from the overlying weight causes it to bury themselves more in-depth in the crust. They are melted by the extreme heat until they are spewed out to the surface again. You may have noticed that this cycle doesn’t conclude on its own. It is affected by other factors such as the wind, temperature and water, that are a part of other spheres.
The Hydrosphere
The hydrosphere includes all the water parts of the planet. It includes water on the surface, subsurface and water vapour in the atmosphere. It undergoes infinite processes every day. The water cycle is one way to understand what is the importance of hydrosphere, its functions and how it supports other spheres.
Water Cycle
An illustration of the water cycle
The ocean and water bodies absorb the sun’s energy and warm up. Transpiration by trees and evaporation of surface water occurs. The water vapour in the atmosphere condenses to form rain clouds and comes down as rain. The rain falls into water bodies and the cycle continues. Other spheres are also impacted during the water cycle.
The Biosphere
Biosphere
An illustration of Biosphere
Biosphere comprises all the living components of the Earth. It also includes organic matter that has not yet decayed. The sphere hugely depends on the other three spheres as follows:
The hydrosphere replenishes plants and animals with water and moisture.
The geosphere renders a solid surface for the plants and animals to inhabit. It also provides heat from beneath the earth.
The atmosphere screens the sun’s UV radiation and helps us receive just enough of the sun’s heat.
A theory known as the ecosystem better explains the interaction of the biosphere with the other spheres.
The Atmosphere
Atmosphere
Different layers of the atmosphere
The gaseous component above the surface of the Earth is known as the atmosphere. It is made of gaseous components and tiny water particles. The gases in the atmosphere are kept in place by the force of gravity. The heat from the sun is radiated to the Earth and is reflected in the atmosphere. The heat from the sun warms up the surface of the earth and causes evaporation, thereby sending moisture into the atmosphere.
The atmosphere comes in layers and the illustration below shows the different layers of the atmosphere. The troposphere is the layer closest to Earth. Humans, animals and plants live in this layer. Birds and aeroplanes also fly in this layer of the atmosphere. In the layers above the troposphere, the air becomes thinner. Beyond exosphere is space.
How Do The Earth’s Spheres Interact With Each Other?
How do different spheres interact with each other?
No sphere works on its own. All the spheres in the system interact and overlap. In the section, we shall discuss the various interactions that occur among the spheres:
1. Hydrosphere and Atmosphere
The evaporation that occurs in the hydrosphere forms the medium for cloud and rain formation in the atmosphere. The atmosphere brings back this water to hydrosphere in the form of rain.
2. Hydrosphere and Geosphere
Hydrosphere provides the necessary moisture required to weather and erode rocks in the geosphere. The geosphere, in turn, allows the ice to melt and the water bodies to flow back into the oceans.
3. Atmosphere and Geosphere
The atmosphere provides the required heat and energy for the breakdown and erosion of rock in the geosphere. Geosphere, in turn, reflects the sun’s energy to the atmosphere.
4. Biosphere and Hydrosphere, Atmosphere and Geosphere
The biosphere receives sunlight and gases from the atmosphere. It collects water from the hydrosphere and a living medium from the geosphere.
All four spheres can often be found in a single location. For example, the soil may contain minerals from the geosphere, moisture within the soil from hydrosphere, insects and plants from the biosphere inhabiting the soil and pockets of air present between the soil pieces. From this, we can conclude that the complete system is what makes life as we know it.

Answer:
You are correct it's the earth!
Explanation:
The reason why is because, the term "elliptical orbit" is used in astrophysics and astronomy to describe an oval-shaped path of a celestial body. The Earth, as well as all the other planets in the Solar System, follow this type of orbit around the Sun. The shape is created by the varying pull of forces, such as gravity, on two objects, such as the Sun and a planet.

Explanation:
Answer:
Inner and outer planets
Explanation:
The asteroid belt is located in orbit between the planets Mars and Jupiter. The asteroid belt not only contains asteroids but minor planets as well. It divides a line between inner rocky planets and outer gas giants. Earth is one of those rocky inner planets. An example of a planet on the outer gas giant side would be Saturn. This belt sort of creates a disk around the sun with the inner planets in-between. This means that the answer to your question should be inner and outer planets.
