Final answer:
Vitamin B12 requires an intrinsic factor for absorption. The intrinsic factor is a protein produced in the stomach which aids in the absorption of Vitamin B12 in the small intestine. Lack of intrinsic factor can lead to vitamin B12 deficiency.
Explanation:
The vitamin that requires intrinsic factor in order to be absorbed is Vitamin B12. The intrinsic factor is a protein produced by the stomach that is necessary for the absorption of Vitamin B12 in the small intestine. Without the presence of intrinsic factor, Vitamin B12 cannot be effectively absorbed, leading to a potential vitamin B12 deficiency.

Active Immunity, Immunity which is acquired by the own immune response of the body.
Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.
x---------------------------------------------------x
Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.

a vaccine works by training the immune system to recognize and fight pathogens, either viruses or bacteria. so certain molecules from the pathogen must be introduced into the body to trigger an immune response. so basically your not really immune your body will just know how to deal with it

by how they produce pitch
by what they are made of
by their frequency
Answers
Musical instruments grouped Option C. by how they produce pitch.
The pitch is decided by the velocity at which the vibrations arise or the frequency. A higher frequency corresponds to a better pitch. Harmonics are responsible for the variety of sounds generated via the instruments in every section of an orchestra. There are sounds that can be higher and louder than the main notice.
The frequency of a wave is the quantity of wave cycles in line with unit time. The wavelength of a wave is the distance between consecutive crests and troughs. The frequency of sound waves is called pitch.
Musical devices produce sound waves which is a longitudinal waves. based on the material that produces sound musical devices can be labeled as membranophones, chordophones, aerophores, electrophones, and many others.

Answer:
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.

Answer:
The vertebral column and vestigial tailbones suggest a common evolutionary pattern among snakes, dogs, and humans, while the presence of limbs in dogs and humans but not in snakes highlights further diversification in their evolutionary paths.
Explanation:
The presence of a vertebral column in all three organisms suggests a common ancestry and evolutionary pattern. While snakes and dogs have tails, humans have vestigial tailbones that indicate a reduced or non-functional tail. This reflects an evolutionary change over time, where humans have lost their tails but still retain a remnant of the ancestral structure. Additionally, the presence of limbs in dogs and humans, but not in snakes, suggests further diversity and modification in the evolutionary patterns of these organisms.
