The percent loss of elephants in Africa from 1970 to 2000 can be calculated by comparing the elephant population between these two years and expressing the difference as a percentage of the 1970 population. This calculation will provide an estimation of the decline in elephant numbers during that time period.
To calculate the percent loss of elephants in Africa from 1970 to 2000, we need to determine the difference in the elephant population between these two years and express it as a percentage of the 1970 population.
Let's assume that the elephant population in Africa was 100,000 in 1970. If the population decreased to 30,000 by 2000, we can calculate the difference as 100,000 - 30,000 = 70,000.
To express this difference as a percentage of the 1970 population, we divide the difference by the 1970 population and multiply by 100:
(70,000 / 100,000) * 100 = 70%
Therefore, the estimated percent loss of elephants in Africa from 1970 to 2000 would be approximately 70%.

Antarctica is a continent that lies entirely in the southern hemisphere. Therefore, option C is correct.
The Antarctic area is dominated by the continent of Antarctica. The Antarctic Convergence spans the Antarctic, a freezing, lonely vicinity withinside the Southern Hemisphere.
The Antarctic takes up around 20% of the Southern Hemisphere. In terms of an overall area, Antarctica is the fifth-largest continent. Antarctica is a one-of-a-kind continent in that it lacks a local human population.
Within the Antarctic Convergence, there are other island territories.

What is an abiotic cycle?
Answer:
An abiotic cycle refers to a non-living process that involves the movement and transformation of chemical elements and compounds in the environment. These cycles do not involve living organisms and are driven by physical and chemical processes.
Examples of abiotic cycles include:
The water cycle, which describes the movement of water between the atmosphere, land, and oceans through processes such as evaporation, precipitation, and transpiration.
The carbon cycle, which describes the movement of carbon between the atmosphere, oceans, and land through processes such as photosynthesis, respiration, and the formation of fossil fuels.

Collisions between galaxies have little effect on the individual stars.
The statement, "Collisions between galaxies have little effect on the individual stars." is true.
Some of the most fascinating phenomena in the cosmos are galaxy mergers. Supernovas and black hole collisions both have a cool aesthetic. Galactic mergers, however, provide all of these and more. Galactic collisions are also a terrific source of inspiration for daydreams about life on planets distant from Earth.
Huge clouds of gas and dust are present within galaxies, and when galaxies meet, these enormous clouds of gas and dust will collide. As a result, the night sky would be filled with hazy pockets of gas and dust that would eventually collapse under their own weight and burst into the creation of brand-new stars. These starburst zones may be seen in images of galaxy mergers taken by the Hubble Space Telescope that astronomers on Earth can see.

How successful has the Clean Air Act of 1990 been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?
The Clean Air Act of 1990 has been very successful in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain.
The Acid Rain Program (ARP), established under Title IV -Acid Deposition Control requires major emission reductions of sulfur dioxide (SO2) and nitrogen oxides (NO), the primary pollutants of acid rain, from the power sector. The SO2 program sets a permanent solution on the total amount of SO2 that may be emitted by electric generating units (EGUs) in the contiguous United States.
The program was phased in, with the final 2010, SO2 cap set at 8.95 million tons, a level of about 1 and 1/2 of the emissions from the power sector in 1980. NOx reductions under the ARP are achieved through a program that applies to a subset of coal-fired EGUs and is closer to a traditional, rate-based regulatory system. Since the program began in 1995, the ARP has achieved significant emission reductions.

Why the convection is so important in the mantle of the Earth?
Convection plays an important role in the mantle of the Earth. It helps to evenly distribute heat and energy throughout the layer, preventing it from becoming unstable.
It also helps to drive the movement of tectonic plates, and is essential for the formation of geological features. Convection is the process by which heat is transferred through the movement of fluids. In the mantle, convection occurs when hot material rises and cold material sinks.
This process is driven by differences in density, which are caused by differences in temperature. Hot material is less dense than cold material, so it rises up and is replaced by cold material that sinks down. This creates a continuous circulation of hot and cold material, which helps to evenly distribute heat throughout the mantle.
This process of convection is essential for the mantle to remain in a stable state. Without the circulation of heat, the mantle would become extremely hot near the core, and very cold near the crust. This could potentially cause the mantle to become unstable, leading to earthquakes and volcanic activity.
The convection process also helps to drive the movement of tectonic plates. As the mantle convects, it creates pressure and movement along the boundaries of the plates. This pressure can cause the plates to slowly move, resulting in the formation of mountains, valleys, and other geological features.

Plant eyes are growth points that have the capacity to develop into both vegetative (leaves, stalks, and roots) and generative (flowers and fruits) plant parts.
Where does the growing point occur on the stem?The first place leaves show up on a stem is called a node. The area between two adjacent nodes is known as a "internode." The internodes of the terminal bud are incredibly short, allowing the developing leaves to climb above and protect the apical meristem that gave rise to them.
Is the first point of growth for the stem?Most primary growth happens in the apices, or tips, of stems and roots. Primary growth is produced by rapidly dividing cells found in the shoot tip and root tip apical meristems. Following cell elongation promotes primary growth as well.

How does convection in the mantle ridge push and slab pull cause the plates to move?
Convection causes the mantle to become hot and buoyant, pushing the plates towards the surface. This force is known as mantle ridge push. Slab pull is another force driving plate movement.
This occurs when the top portion of a subducting plate is pulled downwards by gravity, causing the plate to move. Mantle ridge push is the result of convection in the mantle. Hot material from the mantle rises towards the surface, pushing the plates away from the ridge.
This is similar to the way hot air rises in a convection oven. As the hot material rises, it cools and sinks back down, creating a cycle of convection. This cycle causes the plates to move away from the ridge, creating new crust and pushing the existing plates apart.
Slab pull is driven by the weight of the subducting plate. As the plate dives beneath the surface, it pulls the rest of the plate with it, creating a force that drives the plate away from the subduction zone. This force is strongest near the subduction zone, and it decreases as the plate moves farther away from the subduction zone. Slab pull is responsible for much of the movement of the seafloor plates and is the main driver of plate motion in the oceans.
