Which of the following is not a swimming stroke ?

Détails de la réponse

The swimming stroke that is not listed among the options is the downstroke.

Let's briefly discuss the other three swimming strokes to understand why the downstroke is not considered a swimming stroke:

Crawl: Also known as freestyle, the crawl is the fastest and most commonly used stroke in competitive swimming. It involves a continuous alternating arm motion and a flutter kick. Swimmers move their arms in a windmill-like pattern, pulling the water towards them, while their legs kick in a repetitive up and down motion.

Backstroke: As the name suggests, swimmers swim on their backs, facing up. The main propulsive force in backstroke comes from the alternating arm movement, similar to the crawl stroke. The arms move in a wider arc, and the hands enter the water pinky-first. The legs perform a flutter kick, similar to that of the crawl stroke.

Breaststroke: The breaststroke is the slowest of the four competitive swimming strokes, but it is often considered the most graceful. Swimmers synchronize a frog-like kick and an arm pull to propel themselves through the water. The arms move together in a half-circle motion underwater, while the legs kick outwards and then back inwards simultaneously.

Downstroke: The term "downstroke" does not correspond to any recognized swimming stroke. It may be a term used in other contexts or in certain swimming drills, but it is not a distinct swimming stroke like the crawl, backstroke, or breaststroke.

How many trials are allowed in shot put?

Détails de la réponse

Only 3 trials are allowed in shot put.

Détails de la réponse

The sport injury that results in the break of bone is called fracture.
A fracture occurs when there is a break in the continuity of a bone. This can happen as a result of a sports-related injury where there is a direct impact or excessive force applied to the bone. Fractures can vary in severity, ranging from a small crack to a complete break.
Unlike a sprain, which involves damage to the ligaments connecting bones, a fracture specifically refers to a break in the bone itself.
Similarly, a strain is an injury to the muscles or tendons, while a bruise is the result of damage to the blood vessels under the skin.
It is important to note that fractures require medical attention and proper treatment, which may involve immobilizing the affected area, using casts or splints, and in some cases, surgery. Prompt and appropriate management is crucial to ensure proper healing and minimize complications.

How many points is required to win a badminton game ?

Détails de la réponse

To win a game in badminton, a player or a team needs to score a certain number of points. The number of points required to win a badminton game is 21 points.
However, there are certain rules that need to be followed in order to determine the winner. The winner must also have a 2-point lead over their opponent to secure the victory.
Let me explain the scoring system more in detail. In badminton, each rally results in a point being awarded to one of the players or teams. The rally starts with a serve and ends when the shuttlecock hits the ground within the boundaries, or if a fault is committed by one of the players.
Regardless of who served, a point is awarded to the serving side every time they win a rally. If the serving side loses a rally, the serve will be handed over to the opposing side, and they will have an opportunity to score points.
The game is played until one player or team reaches 21 points, with a 2-point lead. If the score reaches a tie at 20-20, it is called a "deuce". In a deuce, players need to continue playing until a player or team gains a 2-point lead to win the game.
In summary, to win a badminton game, a player or team needs to score 21 points with a 2-point lead over the opponent.

Which of the following part of the human body is responsible for movement ?

Détails de la réponse

Muscles are responsible for movement in the human body. They play a vital role in facilitating various types of movements such as running, walking, and even simple actions like moving an arm or winking an eye. Muscles are special tissues that can contract and relax, enabling them to generate force and movement.
When our brain sends a signal to move a certain part of our body, the muscles associated with that movement receive the message and contract. As the muscles contract, they pull on the bones connected to them through tendons. This pulling action enables the bones to move, resulting in the desired movement.
Muscles work in opposing pairs, known as antagonistic pairs. This means that when one muscle in the pair contracts, the other relaxes to allow movement. For example, when we bend our arm, the biceps muscle contracts, while the triceps muscle relaxes. Conversely, when we straighten our arm, the triceps muscle contracts, and the biceps muscle relaxes.
In summary, muscles are the main component responsible for movement in the human body. They are capable of contracting and relaxing, allowing them to generate force and facilitate various types of movements.

After digestion protein is converted into

Détails de la réponse

After digestion, proteins are converted into amino acids.
During the process of digestion, proteins are broken down into smaller molecules called peptides through the action of enzymes in the stomach and small intestine. These peptides are then further broken down by other enzymes into individual amino acids.
Amino acids are the building blocks of proteins and are crucial for various biological processes in the body. They are essential for the growth and repair of tissues, the synthesis of enzymes and hormones, and the functioning of the immune system.
Once proteins have been converted into amino acids, they can be absorbed into the bloodstream and transported to various cells in the body, where they are used to build new proteins or used as a source of energy.
Therefore, the correct answer is amino acid.

On the other hand, fish, egg, and beans are all excellent sources of protein. Fish, especially fatty fish like salmon, is rich in high-quality protein and also provides healthy omega-3 fatty acids. Eggs are considered a complete protein as they contain all the essential amino acids our body needs. Beans, including options like lentils, chickpeas, and black beans, are also great sources of protein, especially for those following a vegetarian or vegan diet.
To summarize, while fish, egg, and beans are examples of protein-rich foods, rice is not primarily known as a significant source of protein.

How many pairs of the spinal nerve are located in human?

Détails de la réponse

31 pairs of spinal nerves are located in the human body.

The spinal nerves are part of the peripheral nervous system, which is responsible for transmitting signals between the central nervous system (brain and spinal cord) and the rest of the body.

The nerves emerge from the spinal cord in the vertebral column and pass through spaces called intervertebral foramina to reach different parts of the body.

There are 31 pairs of spinal nerves in total:

- 8 pairs of cervical nerves (C1-C8): These emerge from the nekc area and supply signals to the neck, shoulders, arms, and hands.

- 12 pairs of thoracic nerves (T1-T12): These emerge from the upper back area and supply signals to the chest, abdomen, and back.

- 5 pairs of lumbar nerves (L1-L5): These emerge from the lower back area and supply signals to the lower back, buttocks, and legs.

- 5 pairs of sacral nerves (S1-S5): These emerge from the pelvis area and supply signals to the pelvis, genitals, and legs.

- 1 pair of coccygeal nerves: These emerge from the base of the spine and supply signals to the tailbone area.

Each pair of spinal nerves has a sensory component, which carries signals from the body to the spinal cord and a motor component, which carries signals from the spinal cord to the muscles and organs.

By having 31 pairs of spinal nerves, the human body is able to send and receive signals to and from every part of the body, allowing for movement, sensation, and control over bodily functions.

Which of the following helps human sperm with locomotion?

Détails de la réponse

The correct answer that helps human sperm with locomotion is the flagellum. The flagellum is a long, whip-like structure that is present in the sperm. It is responsible for the movement of the sperm through various fluids in order to reach and fertilize the egg.
The flagellum is composed of microtubules, which are tiny structures that give it its shape and strength. These microtubules are arranged in a pattern that allows the flagellum to move in a whip-like motion. This motion propels the sperm forward, allowing it to swim through the female reproductive tract towards the egg.
The movement of the flagellum is powered by a complex biochemical process. Inside the flagellum, there are structures called dynein arms. These dynein arms use energy from ATP molecules to move and bend the microtubules, causing the flagellum to move in a coordinated manner.
The flagellum is essential for the sperm's ability to swim and reach the egg for fertilization. Without a functional flagellum, the sperm would not be able to move effectively and would have a much lower chance of successfully fertilizing an egg.
In summary, the flagellum is the structure in human sperm that helps with locomotion. Its whip-like motion, powered by dynein arms and ATP, allows the sperm to swim towards the egg for fertilization.

The external openings of the nasal cavity that admit air to the lungs are called ?

Détails de la réponse

The external openings of the nasal cavity that admit air to the lungs are called nostrils.
The nostrils, also known as the nares, are the two openings at the base of the nose. They are responsible for allowing air to enter our respiratory system. When we breathe in, air flows through the nostrils and passes into the nasal cavity, which is a hollow space inside the nose.
The nostrils play an essential role in the respiratory process. As we inhale, the air enters the nasal cavity and is filtered, moistened, and warmed before it reaches the lungs. The nostrils are lined with small hairs called cilia, which help to filter out dust, pollen, and other particles from the air we breathe. The nose also contains mucus-secreting cells that moisten the air, preventing it from drying out the delicate lung tissues. Additionally, the nasal cavity has a rich blood supply, which helps to warm the air before it reaches the lungs, ensuring that it is at the right temperature for optimal breathing.
In summary, the nostrils are the external openings of the nasal cavity that allow air to enter the respiratory system. They filter, moisten, and warm the air, preparing it for the lungs to ensure efficient respiration.

Saliva helps in the digestion of starch.
Starch is a carbohydrate that is found in foods like rice, potatoes, bread, and pasta. When we eat foods containing starch, our body needs to break it down into smaller molecules so that it can be absorbed and used for energy.
This is where saliva comes in! When we chew our food, our salivary glands produce saliva that contains an enzyme called amylase. Amylase is responsible for breaking down the starch molecules into smaller sugar molecules called glucose.
By breaking down starch, saliva helps to start the process of digestion and makes it easier for our body to absorb and utilize the energy from the food we eat.
Saliva doesn't directly help in the digestion of proteins, fats, or vitamins. These nutrients are broken down by different enzymes and processes in our digestive system.
In summary, saliva plays an important role in the digestion of starch by producing an enzyme called amylase that breaks down starch into smaller sugar molecules.
