Most of the mass in the solar system is contained in
(A) the Sun
(B) Jupiter
(c) the inner planets
(d) the outer planets

Answers

Answer:

A} the sun

Explanation:

The sun is the greatest and heavier then the other planet

Most of the mass in the solar system is contained in the Sun. Option A is correct.

The majority of the solar system’s mass lies between 99.8% and 99.9% in the Sun. The remainder is distributed among the planets, their satellites, comets, asteroids, and the surrounding interstellar dust and gas.

The solar system's gravitational field is dominated by the sun, which makes up 99.85%. The planets, condensed from the same disc of matter that created the sun, make up 0.135%.

The sun is located at the center of the solar system and is the largest object in the Solar System by far. It is 109 times the size of the Earth. About one million Earths would fit inside the sun.

Therefore, the correct option is option A.

Jonas and his family are moving to another part of the city. As Jonas, his brother, and his Dad were driving one of the trucks filled with furniture to their new home, Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. Which Newton's Law explains why this happens?

Answers

Answer:

Newton's 2nd Law of Motion

Explanation:

A force applied to an object at rest causes it to accelerate in the direction of the force. It is easier for the empty truck to stop than a full truck, because the full truck has more mass than the empty one.

This phenomenon is explained by the law of inertia i.e. the first law of Newton.

What is Newtons's first law?

According to Newton's first law, unless pushed to alter its motion and direction by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. It is also known as the law of inertia.

A body's inertia is a quality that makes it resist changes to its state. The amount of a body's inertia in translational motion is determined by its mass. A heavier body's consistent motion or state of rest is challenging to alter, and the opposite is true for lighter bodies. This is why the truck filled with furniture takes longer to stop.

Thus, when Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. It is explained by the first law of motion (law of inertia).

Convergent evolution is a process where organisms independently evolve traits. Some molecular data place the giant panda in the bear family (Ursidae) but place the lesser panda in the raccoon family (Procyonidae). Consequently, the morphological similarities of these two species are probably due to

Answers

Answer:

analogous structures

Explanation:

Analogous structures play similar and/or identical functions in unrelated organisms. For example, moths and bats both have wings, even though they aren't related. Convergent evolution is a process that generates analogous structures in organisms that don't share a common ancestor with such structures. Moreover, homo-logous structures are shared traits between organisms that share a common ancestor. On the other hand, divergent evolution is a process associated with the accumulation of phenotypic differences between organisms within a species, which eventually lead to speciation.

___ describes how much energy an earthquake releases ​

Answers

Answer:

Magnitude

Explanation:

Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol

Answers

Answer:

The correct answers are described in the Explanation section.

Explanation:

The function of the structures in the cell membrane are as follows:

a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.

b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.

c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.

d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions  in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.

e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.
