While exercise generally benefits all of the glands, why is it particularly beneficial for the pancreas?
A.
Exercise increases the levels of the hormones that the pancreas produces.
B.
Physical activity positively impacts blood sugar, giving the pancreas less work.
C.
The pancreas can only properly regulate hormones when the body is in motion.
D.
The pancreas is structured more like a muscle than a gland, so it benefits from stretching.


PLEASE NO LINKS

Answers

Answer:

B

Explanation:

The pancreas is responsible for regulating blood sugar, exercise gives it less work to do

Excercise is particularly beneficial for the pancreas because physical activity positively impacts blood sugar, giving the pancreas less work. Correct option is B.

When you engage in physical activity, several things happen that benefit the pancreas:

Increased Insulin Sensitivity: Exercise helps improve the body's sensitivity to insulin. This means that cells become more responsive to the insulin signal, allowing glucose to enter the cells more effectively. This can help prevent insulin resistance, a condition where cells don't respond properly to insulin and blood sugar levels rise.

Improved Blood Sugar Regulation: Exercise can lower blood sugar levels by facilitating the uptake of glucose into cells for energy. This can reduce the burden on the pancreas to produce excess insulin to manage high blood sugar levels.

Reduced Risk of Type 2 Diabetes: Regular physical activity is associated with a reduced risk of developing type 2 diabetes, a condition characterized by impaired blood sugar regulation. By helping maintain healthy blood sugar levels, exercise supports the pancreas in its role of insulin production.

what are the slight fluctuations seen in maps of the cosmic background radiation?

Answers

If you look very closely, there are slight fluctuations from place to place. farther into space-further back in time-then when we look at the farthest galaxies. What are the slight fluctuations seen in maps of the cosmic background radiation? A reduction in the curvature of space.

The beginning of the formation of galaxies and clusters of galaxies are the slight fluctuations seen in maps of the cosmic background radiation. So, the correct option is C.

What is Cosmic background radiation?

The cosmic background radiation is defined as the microwave radiation that fills all of space which is a remnant that provides an important source of data on the early universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark.

It is also called the Cosmic Microwave Background (CMB) or electromagnetic radiation filling the universe which is a residual effect of the Big Bang that happened 13.8 billion years ago. The beginning of the formation of galaxies and clusters of galaxies are the slight fluctuations seen in maps of the cosmic background radiation.

25 n object requires a 5. 0 n to start moving over a horizontal surface. What is the coefficient of static friction?.

Answers

Answer:

μ=1/5=0.2

Explanation:

using the formula

Fs=Fn*μ

Where

Fs is the static force

Fn = Normal force

μ= coefficient

so if Fn=25n

and it requires 5 n to start moving, means the max Fs is 5n

5=25μ

μ=5/25

μ=1/5=0.2

A block of mass m is initially at rest on a rough horizontal surface when a constant force F is exerted on it, as shown. The block accelerates to the right and is moving with speed v once it has moved a distance d. Which of the following equations can be used to solve for the force of friction exerted on the block by the surface?

Answers

The equations that can be used to solve for the force of friction exerted on the block by the surface is F- f = mv² / d

The constant force F is exerted on the block of mass and it accelerates with a speed, v and covering a distance of d in the direction of the force. The force of friction is an opposing force to the applied force.

Therefore,

using Newtons third law

F - f = ma

a = v/t

t = d/v

F - f = m × v / t

F- f = m × [tex]\frac{v}{\frac{d}{v} }[/tex]

F- f = m × v²/d

Therefore,

F- f = mv² / d

In which scenario below does the ball have more gravitational potential energy when sitting at the top. Why?

Answers

b. because gravity can just pull it straight up than in sort of a zigzag way (A) where it won’t have as much space to move.

The B figure has got more gravitational potential energy because gravity can draw it up straight rather than in a fashion (A) that would leave it with less room to travel.

What is Gravitational Potential Energy?

The work (energy exchanged) per mass that would be required to transport an object to a point from a set reference location is the gravitational attraction at that location. It mimics the electric potential, with mass acting as the charge. There is a negative potential at any finite distance because the benchmark location, where the potential is zero, is conventionally indefinitely far from any mass.

The subject of potential theory is based on the gravitational potential, sometimes referred to as the Newtonian potential in mathematics. The electrostatic and popular throughout the world fields produced by ellipsoidal bodies that are uniformly charged or polarized can also be resolved using this method.

Suppose the gravitational force between two spheres is 30 N. If the magnitude of both masses doubles, and the distance between them tripled. What is the force between the masses?

Answers

If both masses double in size and their separation between them triples. 13..33 N will be the force between the masses.

What is gravitational force?

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

Given data:

The gravitational force = 30 N

Mass 1 =m₁

Mass 2=m₂

Distance between charges = R

Condition given:

Mass 1 = 2m₁

Mass 2= 2m₂
