Using all the words below, write a short paragraph explain convection currents
Convection Currents
Mantle
Crust
Heat
Less dense
movement
More dense
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.Normal hemoglobin

The microscope is an essential tool in Biology. It provides us with important data on specimens being examined.
The (1) has various magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. On the other hand, the

magnification of the Objectives. If the eyepiece has a magnification of 10x and the Objective has (9)
then
the specimen's magnification is 400x. In addition, turning the stage knob upward will result to moving the specimen as
seen in the microscope downward while turning the stage knob to the left will move the specimen to the right as seen
under the microscope. Finally, the specimen when seen under the microscope appears (10)
Answer:
The correct answer would be -
1.) objectives
2.) eyepiece
3.) glass slide
4.) coverslip
5.) pencil
6.) mirror
7.) field of view
8.) magnification
9.) 40x
10.) inverted
Explanation:
Objectives of the microscope have magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. The nosepiece is found between the stage and the eyepiece or ocular lens. Glass slide is the slide where a specimen is placed for the study and covered with a coverslip, bubble should be avoided while placing the coverslip.
Mirrors need to adjust to seeing the field of view by adjusting the light. After computing the magnification there would be a final image of the specimen that would be inverted due to the two lens used here.

Explain why NON-RENEWABLE resources are NOT renewable even though plants and animals continue to die all the time.
Answer:
The correct answer is - these resources take million years to be replenished.
Explanation:
Non-renewable resources are the resources that come from a source that will finish ultimately or run out or can not be replenished in one or more human life cycles. These sources might take million years to replenish.
Most non-renewable resources are fossil fuels, coal, natural gas. Fossil fuels, cols are were formed as the remains of dead plants and animals but takes millions of years to decay, under huge amounts of pressure and heat.

How is water formed during the electron transport chain
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.

Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
Answer:
Charakan
Explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.

Describe the amount of sunlight at the poled and at the equator throughout various times of the year. Why does this occur?
Answer:
Neither of the poles are tilted towards the sun. Hence, the sun rays fall directly on the equator due to which all the places on the Earth experience equal daylight hours and equal night time hours that is, 12 hours of day and 12 hours of night on all the places of the Earth.
Answer:
The fact that the equatorial Sun is always so close to the zenith at solar noon explains why the tropical zone contains the warmest regions on the planet overall. Additionally, the Equator sees the shortest sunrise or sunset because the Sun's path across the sky is so nearly perpendicular to the horizon.
