This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answers
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Researchers are conducting a study to see if exposure to an occupational toxin leads to brain tumors. The researchers recruit 1,000 men who work at a steel factory (all of whom do not have a brain tumor in 2000) and use questionnaires as well as measuring devices to see who is exposed to the occupational toxin Airflyte. After the baseline assessment, 493 of the workers were exposed to Airflyte while the others were not. After 10 years of follow up, 308 of the workers exposed to Airflyte developed brain tumors while 77 of the men not exposed to Airflyte developed brain tumors. Set up a 2x2 table with the data given.

There are only four parts of skill related fitness in the options; they are:
Speed
Agility
Balance
Coordination
Explanation:
Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.
However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:
- Speed: This refers to the ability to run a distance in a short time frame.
- Agility: This is the ability to move easily and quickly in different directions
- Balance: The ability to maintain an upright body position during training or physical activity
- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.
Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
Final answer:
The five components of skill-related fitness are Speed, Coordination, Agility, Balance, and Muscular Strength. Each plays a different role in physical activities and sports.
Explanation:
The five parts of skill-related fitness are; Speed, Coordination, Agility, Balance, and Muscular Strength.
- Speed: It is the ability to move quickly. It is crucial in many sports such as sprinting, swimming, and soccer.
- Coordination: This refers to the ability to use different parts of the body smoothly and efficiently together. For example, dribbling a basketball while running.
- Agility: It is the ability to change the direction of the body quickly and effectively while maintaining control. Gymnasts, soccer players, and basketball players display good agility.
- Balance: It involves maintaining body equilibrium to prevent falling. It's used in activities like yoga, gymnastics and ice-skating.
- Muscular Strength: Not to be confused with muscular endurance, muscular strength is the amount of force that a muscle can produce in a single effort. It’s used in activities such as weightlifting and shot put.

The statement "white blood cells can leave the blood circulatory system" is definitely true.
What is the circulatory system?
The circulatory system may be defined as a type of body system that significantly contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.
White blood cells can also be known as the soldiers of the body. They can leave the bloodstream and migrates into tissues in the body. White blood cells play an important role in the immune system.
Here the different blood cells have different functions: Some fight intruders such as bacteria, viruses, parasites, or fungi themselves and render them harmless.
Various studies and reports suggested that the white blood cells -- actively open large gaps in the internal lining of the blood vessels, so they can exit through the vessel walls and rapidly get to areas of infection.
Therefore, the statement "white blood cells can leave the blood circulatory system" is definitely true.
