Answer:

The effects of gravitational force are :

i) The Sun's gravitational pull keeps our planet orbiting the Sun.

ii)The motion of the Moon is affected by the gravity of the Sun AND the Earth.

iii) The Moon's gravity pulls on the Earth and makes the tides rise and fall every.

iv) The Earth's gravitational force accelerates objects when they fall.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

Answer:

YES

Explanation:

Glycogenolysis can still occur during exercise even if a person is administered a drug that blocks the Beta receptors for norepinephrine. This is because glycogenolysis is mainly regulated by the hormones epinephrine and glucagon, which are released from the adrenal glands and do not require norepinephrine for activation. Therefore, blocking the Beta receptors for norepinephrine has no effect on glycogenolysis.

The prompt is culled from "HonerScience" Gizmo. The objective is the compare the Planetary motion of Pluto's Orbital Radius, against the period of it's Orbit as depicted in the Gizmo. It is to be noted that Pluto's Orbital Radius is 39.529 AU while it's period of Orbit is 249 years.

For roughly circular orbits, the orbital radius is the distance between an item in space and the body it is circling. When an object circles a body in space, it spins around it, forming a circle or an ellipse depending on the orbit.

If the mass of the orbiting star is known, Kepler's Third Law may be used to calculate the planet's orbital radius (R3=T2Mstar/Msun, the radius is in AU, and the period is in earth years).

The earth's radius and the radius of its orbit around the sun are 6371 km and 149x109 km, respectively.

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Unless an unbalanced force is acting on an object, Newton's first law states that it will stay at rest or move in a straight line at a constant speed.

Newton's first law states that any object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the application of an external force. Inertia is the propensity to resist changes when things are moving.

According to Newton's First Law of Physics, moving objects continue to move in the same direction unless they are affected by an imbalanced force. Things moving include among others, the US dollar, rates, inflation, and oil.

Answer: 2, Endocrine.

Explanation:

They became extinct, so they did not exist when the younger rock layers formed. Option D.

The most likely scenario based on the information provided is that the organisms that became fossilized in older rock layers became extinct, and therefore, they did not exist when the younger rock layers formed.

Fossils are the preserved remains or traces of organisms from the past, and they provide valuable insights into the history of life on Earth. The distribution of fossils in rock layers follows the principle of superposition, which states that younger rock layers are deposited on top of older ones.

This implies that the fossils found in older rock layers represent organisms that lived in the past and were preserved through the fossilization process.

If the older rock layers contain fossils of many kinds of organisms that are not found in younger rock layers, it suggests that those organisms no longer existed by the time the younger rock layers formed. The absence of their fossils in younger layers indicates that either the organisms became extinct or their populations shifted to different habitats or regions where their remains were not preserved as fossils.

This phenomenon aligns with the concept of extinction, which is the complete disappearance of a species or a group of organisms. Extinction can occur due to various factors such as environmental changes, competition, predation, or other selective pressures.

Organisms that became extinct would not be present in subsequent rock layers because they were no longer alive or did not have a viable population to leave behind fossil remains.

Therefore, the most reasonable explanation is that the organisms that became fossilized in older rock layers became extinct, and this is why they are not found in younger rock layers. SO Option D is correct.

Answer:

calcium is not a main element of calcium . question 2 hemoglobin is a globular protein with an embedded heme group. so a transportation protein and question 3 the building blocks of proteins are amino acids.

Explanation:

1.  The element that is not part of the four main elements of amino acids would be calcium

2. Hemoglobin is a type of transport protein.

3. The building blocks of proteins are amino acids.

Amino acids represent the building blocks of proteins. They are made up of four main elements in the form of carbon, nitrogen, oxygen, and hydrogen. Some amino acids have other elements such as sulfur in methionine and cysteine. Amino acids are joined together by peptide bonds to form proteins.

Hemoglobin is a protein molecule whose characteristic red coloration is caused by the presence of iron. The molecule is found abundantly in the blood of mammals and primarily serves as an oxygen transporter in the circulatory system.  Hemoglobin reversibly bonds with oxygen in the lung to form bright red oxyhemoglobin. The oxygenated blood is then transported around the body during which the oxyhemoglobin bond is broken to release oxygen to different cells of the body.

In summary, calcium is not part of the four main elemental compositions of amino acids, amino acids are the building blocks of proteins, and hemoglobin is primarily a transport protein.
