Answer:

Gravity

Explanation:

Gravity is what causes you to weigh more or less.

What is gravity? Gravity is the force that pulls things together. Larger things with larger masses have more gravity. When you are on Earth, you would weigh more than on the moon, about 6 times more, in fact, because the gravity on Earth is 6 times stronger.

Carbon and Hydrogen.

Answer:

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Answer:

Keep in mind this changes from microscope to microscope.

Explanation:

On most classroom microscopes, there will be two knobs on either side of the scope.  These will increase or decrease the height of the "stage", which is how you "focus" the microscope.  The larger knob will move the stage the most, and thus, is called the coarse focus.  The smaller knob is called the fine focus, and, you guessed it, will move the stage the least.  There are usually three "objective lenses".  Each will have a different magnification and will be listed on the lens itself.  It rotates around the "revolving nosepiece".  MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!!  If you don't you WILL break the slide and you WILL get death looks from the teacher.

On the stage, there are two clips.  They move NOT up and down, but they spin.  what you want to do is to move the slide into the clips.  They will not break if you do not bend them more than what the slide will bend them to.

The technique for focusing the microscope is really easy once you do it a few times.  After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible.  Once you do that, from there use the fine focus knob to make the object most visible.

These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.

The cold tide may cause the Atlantic currents that bring warmth to Western Europe to slow down. According to NASA's news release, disruptions to the Gulf Stream would have a negative impact on ocean life and the communities that rely on it.

If all the ice on Antarctica, Greenland, and in mountain glaciers around the world melted, sea level would rise by approximately 70 meters. The ocean would engulf all coastal cities. And the land area would be significantly reduced.

The loss of older ice indicates that the Arctic ice cover is thinning. Evidence also suggests that the melt season has lengthened; ice is melting earlier in the year and freezing later than it used to.

Thus,The cold tide could slow the Atlantic currents that bring warmth to Western Europe. Disruptions to the Gulf Stream, according to NASA, would have a negative impact on ocean life and the communities that rely on it.

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s

kinetic energy is given as

5) when speed is 6 m/s

kinetic energy is given as

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answer:

A) True

Explanation:

The answer is A) True. A physical change and a chemical change can happen at the same time. For example, when a candle burns, the wax melts (a physical change) and the wick and some wax burn (a chemical change). Another example is when iron rusts, it changes its color (a physical change) and its composition (a chemical change).

Asteres planetoid, or 'wandering stars,' was the term used by Greek astronomers to describe star-like objects that appeared to move across the sky.

The term has been applied to a wide range of objects, including the moon, satellites, the sun, and asteroids.

A planet, according to the International Astronomical Union (IAU), is a body that orbits the Sun, is massive enough for its own gravity to keep it around, and has 'cleared its neighborhood' of smaller objects approaching its orbit.

The properties of all of these material vary from each other. Paper, cardboard and plastic are insulators and metals and conductors. Each of them has different physical properties.

The physical properties of a substance include properties which changes its physical structure, size, shape, phase etc. Solubility, conductivity, resistance etc. are also physical properties.

Here, paper, cupboard and plastic are insulators and they does not conduct electricity. Whereas, metals are very good conductors and they have wide range of applications in optoelectronic devices.

Each of these materials has different melting temperature and different uses. Their density also vary significantly. The paper is the less dense one here and metals are denser.

The applications of these materials are based on their physical properties.
