What are the basic components of an effective golf swing?O Grip, Setup, Stance, Backswing/Downswing

O Attitude, Effort, Compassion

O Strength, Power, Finesse

O Athletic Ability, Talent, Sportsmanship

Answers

The basic components of an effective golf swing include A. Grip, Setup, Stance, Backswing/Downswing.

It should be noted that a good golf wing should have main parts which are the grip, setup, stance, and backswing or downswing.

The golf player should swing effectively and maintain the proper spine angle in the positions. When hitting a golf ball, it's important to look at the back inside quarter of the ball. This is vital to enhance an inside swing.

Final answer:

An effective golf swing is composed of five basic components: grip, setup, stance, backswing, and downswing. Each step aids in achieving a versatile, controlled, and powerful swing which contributes to a player's overall performance.

Explanation:

The basic components of an effective golf swing include the grip, setup, stance, and the actions of backswing and downswing. The grip refers to how you hold the club, where a neutral grip allows the best versatility. The setup includes positioning in relation to the ball, posture, and alignment to the target. The stance concerns the placement of your feet, the ideal width being about shoulder-width apart. Commencing the swing, the backswing is the initial upward movement of the club. It should be a smooth, controlled motion, preparing for the energetic downswing. The downswing is the movement that launches the ball, starting from the ground up with your feet and legs initiating the motion.

In the practice of ________, scabs from smallpox victims were used to immunize susceptible individuals against smallpox.

Answers

Answer: Variolation

Explanation:

Variolation can be defined as the condition in which the inocolutaion of the individuals with the infectious materials, scabs or pulses from the smallpox victim.

This was introduced by the route of nasal passage or injected intravenously. The infection that developed because of this was less than normal and it provided protein against more serious disease.

Hence, the correct answer is Variolation.

A student studies art and learned that he has several layers including inner and outer cores the student will make a model of the inner and outer cores of earth which model would be most like earths actual inner and outer cores A: A pool of liquid inside a solid metal ball. B: Metal ball with a slightly smaller solid metal ball inside it. C: A solid metal ball in the middle of a pool of liquid. D: A pool of one type of liquid in the middle of a pool of another type of liquid

Answers

Answer:

C: A solid metal ball in the middle of a pool of liquid.

Explanation:

Since the student is studying the earth, the core area is made up of a solid metal ball in the middle of a pool of a liquid.

  • The core is the inner most part of the earth.
  • It exists in the middle of the earth.
  • The core is divide into two layers; inner core and outer core.
  • The inner core is a solid ball of metal.
  • The outer core is a liquid metal under high temperature and pressure.

The difference between the cellular make-up of a living organism and an aluminum can is the _____. ability to use energy ability to move bonding structure sensitivity

Answers

Answer: The answer would be ability to use energy.

Explanation:

One of the main differences between living and non-living organisms is that the living organisms are able to use energy to maintain homeostasis.

The non-living things such as aluminium can not utilize energy for itself.

However, a living cell uses energy for all its vital functions such as digestion, respiration, et cetera.

Answer:

ability to use energy

Explanation:

The cellular composition between a living organism and an aluminum can is very different. For starters, only living things have cells, as this is the basic structure of living things. In addition, the cells of living things produce and use energy so that the metabolic processes that allow life to continue happen. For this reason, we can say that the difference between the cellular composition of a living organism and an aluminum can is the ability to use energy.

What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.

Answers

Answer:

Explanation:

Step 1: Generating a Proton Motive Force

The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons

The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins

As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix

The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)

Step Two: ATP Synthesis via Chemiosmosis

The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix

This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase

As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP

Step Three: Reduction of Oxygen

In order for the electron transport chain to continue functioning, the de-energised electrons must be removed

Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked

Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient

In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted
