I hope it can help you a lots Thanks.
Introduction
Passive transport(Opens in a new window) is a great strategy for moving molecules into or out of a cell. It's cheap, it's easy, and all the cell has to do is sit there and let the molecules diffuse in. But...it also doesn't work in every situation. For instance, suppose the sugar glucose is more concentrated inside of a cell than outside. If the cell needs more sugar in to meet its metabolic needs, how can it get that sugar in?
Here, the cell can't import glucose for free using diffusion, because the natural tendency of the glucose will be to diffuse out rather than flowing in. Instead, the cell must bring in more glucose molecules via active transport. In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient.
Here, we’ll look in more detail at gradients of molecules that exist across cell membranes, how they can help or hinder transport, and how active transport mechanisms allow molecules to move against their gradients.
Hello Lanephillips0!
There are many ways in which we can improve our posture, some of which may be simple or difficult. The first and easiest way to maintain a better walking stride is to stand up straight, and keep your eyes forward. The second way is to keep your shoulders back and steady, which will help align your spine. The final and hardest way is to suck in your stomach and wear a back compressor.
Hope this will help you out!

Answer:
<h2>This statement is true</h2>
Explanation:
- Power is the fitness skill associated with the rate at which strength could be utilised.Practicing sports skill is one of the method of increasing the skill related fitness.
<h3>
Six components of Skill related fitness are:Agility, Balance, Coordination,Speed,power & Reaction time. </h3>
- Agility: ability to change & control the position & direction of the body while keeping the continuous & fast motion. For eg. changing the directions for hitting a tennis ball.
- Balance: ability of a body stabilisation when a person is standing or moving.For eg. in line skating
- Coordination: making combined use of the senses with body parts during movement.For eg.dribbling a basketball.
- Speed : ability of moving the body parts in a very fast manner eg.a footballer outrun the defense to receive a pass, tennis player move forward to get a drop shot.
- Power: It is a combination of both muscular strength and speed.
- Reaction Time: an ability of responding quickly to what we feel.For eg. stealing a base in baseball.
*Skill related fitness means it consists of skill which will enhance one's performance in athletic or sports event.
