what makes living things and non-living things successful in their attempts to take flight?
Answer:
Any living or non-living thing trying to take flight will have two forces working against them: gravity and drag. Gravity is the force that the Earth exerts on all things pulling them back towards its centre. ... Birds also have two forces that help them in their attempts to take flight.
Explanation:
If living things and non-living things have the ability to work and resist two forces which are gravity, and drag. They will take a successful attempt in their flight.
What do you mean by Living things?Living things may be defined as creatures that have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce, etc.
Birds also resist these two forces. And take a successful attempt of flight. The air resists the motion of the bird and the resistance force, is called drag. Gravity is the downward acting force that is mediated by the earth's surface.
Therefore, If living things and non-living things have the ability to work and resist two forces which are gravity, and drag. They will take a successful attempt in their flight.

If 1000 units of energy are available at the producer level of the energy pyramid, about how many units are available for first-level consumers? Second-level consumers? Third-level consumers?
Answer:
The next level after the producer would receive 100 units of energy.
Explanation:
The amount of energy that passes on to the next level is only 10%.
If the producers start with 1000 units, only 10% passes on. The next trophic level would have 100 units, the next after that would have 10, and so on. Only 10% of the energy is passed on into the next level.

Why would a change in brain size be important for the evolution of hominids as opposed to other species? (Think beyond a ‘big brain means they are smarter.’ What can you do with your brain that other organisms may not be able to?)
Answer:
Bigger brain helped our ancestor survives.
Explanation:
Change in brain size is very important for the evolution of hominids as opposed to other species because bigger brain helped our ancestor survives when the environmental conditions changed with the passage of time. They use their brain to avoid negative effects of environment change. I do a lot of things with my brain that other organisms may not be able to do that such as inventions of new technologies.

The Majority of the untied states resides in what atmospheric convection area
Answer:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts. In addition to heat transfer, convention can be driven by other properties (e.g., salinity, density, etc)
Explanation:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere.
What do you mean by convection?Convection is the process of losing heat through the movement of air or water molecules across the skin. The use of a fan to cool off the body is one example of convection.
Convection currents are present in the air– A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air.
The best description of a convection current is that e. it is the process in which warm material expands and rises while cool material contracts and falls.. Convection current in the atmosphere causes warm air to rise up from the surface.

The speed of the rotation of Earth has the greatest effect on which of the following?
Answer:
?***##################
The speed of the Earth's rotation has the greatest effect on the length of a day.
What happens during Earth's rotation?
The Earth rotates once on its axis in approximately 24 hours, and this rotation determines the length of a day. The Earth's rotation speed is not constant, but it is gradually slowing down over time due to various factors, such as the gravitational influence of the moon. As a result, the length of a day has increased over geological time.
The speed of the Earth's rotation also affects other aspects of the planet, such as the distribution of ocean currents, atmospheric circulation patterns, and the formation and behavior of weather systems. However, the length of a day is the most directly and immediately impacted by changes in the Earth's rotation speed.

a healthy body? Describe in detail.
Answer: something that i notice about the path oxygen is that anytime i eat something oxegen comes in and then after that the remaining oxegen comes out and then the lefover oxegen stay inside the respiratory system
Explanation:
The path oxygen takes inside the metabolism simulation is ; Diffusion
When we breathe in air the oxygen molecules contained in the air we breathe in move inside into our capillaries and from the capillaries into the body cells of an individual through a specific pathway known as diffusion.
As the oxygen moves into the the body cells from the capillaries the carbon dioxide ( by product ) contained in the body cells moves into the capillaries and is expelled out through the lungs.
Hence we can conclude that the path oxygen takes inside the metabolism simulation is diffusion.

Explain how natural processes, like earthquakes, unearth new rock layers and fossil
Answer:
Earthquakes shake Earth, sometimes causing cracks. When Earth shakes, it moves the crust around and this could help expose new rock layers and fossils.
The study of a living being is called biology.
Earthquake is defined as any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks.
When an earthquake occurs it moves the tectonic plate and it will lead to the formation of a new place. sometimes it cracks the earth's surface which will show up what is inside it.
The study of that cracks leads to unearthing the new fossils.

Which side or sides of the box have the same dimensions as those of a cross section parallel to side AEHD
Answer:
Sides AEHD and BFGC have the same dimensions as a cross section parallel to side AEHD.
Explanation:
Sides AEHD and BFGC have the same dimensions as a cross section parallel to side AEHD.
Answer:
part A : Sides A-E-H-D and B-F-G-C have the same dimensions as a cross section parallel to side A-E-H-D
part B: The length of the side is 3 inches, and the width of the side is 3 inches.
The perimeter can be found using this formula:
perimeter
=
2(length + width)
=
2(3 + 3)
=
2(6)
=
12 inches.
Part C:The dimensions of a cross section that is parallel to side AEHD are the same as those of side A-E-H-D. So the perimeter of a parallel cross section is the same as the perimeter of side A-E-H-D, or 12 inches.
part D: The cross section that passes through the points A, F, G, and D is the rectangle A-F-G-D.
A-F = D-G = 5 inches
