Answer:

Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).

Answer:

Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km), and an eccentricity of 0.0934 The planet orbits the Sun in 687 days and travels 9.55 AU in doing so making the average orbital speed 24 km/s.

The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and perihelion distances—they are 1.6660 and 1.3814 AU

Explanation:

Answer: i hope this helps :)

-- 687 days

-- After years of analysis, Kepler discovered that Mars's orbit was likely to be an ellipse, with the Sun at one of the ellipse's focal points. This, in turn, led to Kepler's discovery that all planets orbit the Sun in elliptical orbits, with the Sun at one of the two focal points.

-- From our point of view as we race around the Sun, Mars is falling behind; consequently, we see Mars moving in a retrograde direction from night to night across the sky. Since the Earth always moves around the Sun faster than Mars, you might imagine that Mars's motion will always be retrograde.

-- Basically, that planets do not move with constant speed along their orbits. Rather, their speed varies so that the line joining the centers of the Sun and the planet sweeps out equal parts of an area in equal times. The point of nearest approach of the planet to the Sun is termed perihelion

The volume using the cylinder formula  : V=πr²h

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume

If a certain amount of gas is heated, the volume will increase

So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable

Because the tube is cylindrical, to find the volume using the cylinder formula

[tex]\tt V=\pi.r^2.h[/tex]

Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

Answer:

1. Temp of gas 40C,  Height of the column of gas 6.7

2. Temp of gas 313K, Volume of gas 0.84

Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.

Answer:

A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

Answer:

I would think B, an estuary. But I'm not sure.

Explanation:

The area where the plants should be find in which the water should be tolerated should be estuary.

An estuary refer to the enclosed body with respect to the brackish water  that have one or more rivers or streams that should be flow into it. Also, there should be free connection to the open sea. It should be considered as the transition zone that lies between the river environment and maritime environment

Therefore, we can conclude that the option b is correct.

Answer: The box is moving downward with increasing speed.

Explanation:

The diagram models the forces acting on a box. 2N 2N- Box - 2 N 5 N .The box is moving downward with increasing speed best describes the motion of the box.

The normal force acting on the box is equal to and opposite to its weight. This term equals the force of gravity when the box is on a level surface. To calculate the normal force of the box, use our given mass and gravity's acceleration.

When an object interacts with another object, it experiences a push or pull that causes it to change state, either from rest to uniform motion. It is a magnitude and direction vector quantity.

A representation of the forces acting on the object. The object is represented by a dot, and forces are represented by arrows pointing away from the dot. Force diagrams are another name for them.

Thus, The box is moving downward with increasing speed best describes the motion of the box.

Answer:

No of protons = 15

Explanation:

Given that,

Atomic number = 15

Mass number = 31

We need to find the no of protons in the atom.

We know that,

No of protons = Atomic no of the atom

No of protons = 15

Hence, there are 15 protons in the atoms.

[Top row] - Chemical bonds

[2nd Row L-R] - Force, Ionic, Covalent

[3rd Row L-R] - Atoms, Lost or Gained, Shared

[4th Row L-R] - More stable, Metal and Nonmetal, Nonmetal and Nonmetal

Explanation:

Chemical bonds are a force that hold together atoms in a substance to make compounds more stable.

Chemical bonds include two kinds: Ionic and Covalent.

Ionic in which electrons are lost or gained where attraction is between a Metal and Nonmetal.

Covalent in which electrons are shared where attraction is between a nonmetal and nonmetal.

I have been able to fill the concept map using the correct terms or phrases. The concept map talks about chemical bonds. There are two types of chemical bonds; which ionic bond and covalent bond.  

The most chemically reactive element among the listed elements is Radium (Ra). The correct option is C.  radium (Ra)

The elements listed are alkaline earth metals, that is, they belong to group 2 of the period table.

The reactivity of alkaline earth metals increases down the group. That is, the reactivity increases with increase in atomic mass.

Among the listed element, radium (Ra) has the greatest atomic mass and it is the last element as we go down the group.

Hence, the most chemically reactive element among the listed elements is Radium (Ra). The correct option is C.  radium (Ra)

Explanation:

1. Two substances, both solids, start at the same temperature. You transfer

the same amount of energy into both solids, but substance 1 becomes a

liquid before substance 2. Which substance has a stronger molecular

attraction?

A Substance 1

B Substance 2

Please help I will give you Brainlyest

Substance 2 has a stronger molecular attraction.

Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.

Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.

Hence, Substance 2 has a stronger molecular attraction.
