D

Explanation:

Introduction:
In this question, we are asked to determine the number of eyes we have. The correct answer is option 'B', which states that we have two eyes.

Explanation:
Our eyes are one of the most important sensory organs in our body. They allow us to see and perceive the world around us. Here is a detailed explanation of why we have two eyes:

1. Binocular Vision:
One of the main reasons we have two eyes is to achieve binocular vision. Binocular vision refers to the ability to perceive depth and three-dimensional objects. Each eye captures a slightly different image of the same object due to their position on our face. The brain then combines these two slightly different images to create a single, three-dimensional image. This helps us judge distances accurately and have a better perception of the world.

2. Field of View:
Having two eyes also increases our field of view. Each eye has a certain range of vision, and when we have two eyes, these ranges overlap, allowing us to see a broader area without having to move our heads. This is particularly useful for detecting objects or dangers from the sides or periphery of our vision.

3. Peripheral Vision:
Our eyes have a central area of focus called the fovea, where the vision is sharpest. However, the peripheral vision outside this central area is not as detailed but can detect motion and changes in the environment. Having two eyes allows us to have a wider peripheral vision, enhancing our overall awareness of our surroundings.

4. Depth Perception:
Two eyes also help in depth perception, which is the ability to judge the distance between objects accurately. When we have only one eye or if our vision is impaired in one eye, our depth perception is compromised. With two eyes, we can perceive depth by comparing the slightly different images captured by each eye.

Conclusion:
In conclusion, the correct answer to the question is option 'B' - we have two eyes. Our two eyes work together to provide us with a more comprehensive field of view, depth perception, and a three-dimensional view of the world around us.

Answer:
The organ for the sense of taste is the Tongue.
Explanation:
The tongue plays a vital role in the sense of taste. It contains thousands of taste buds that are responsible for detecting and identifying different flavors. Here is a detailed explanation of how the tongue functions in the sense of taste:
1. Taste Buds: The tongue is covered with small bumps called papillae, and within these papillae are taste buds. Each taste bud contains specialized cells that detect different taste sensations.
2. Taste Sensations: The taste buds can detect five primary taste sensations: sweet, sour, salty, bitter, and umami (savory). These taste sensations help us distinguish between different flavors in the foods we eat.
3. Taste Receptors: Within the taste buds, there are taste receptors that send signals to the brain when they come into contact with specific molecules in food. These receptors are responsible for translating chemical information from the food into electrical signals that the brain can understand.
4. Brain Interpretation: Once the taste receptors send signals to the brain, the brain interprets these signals and allows us to perceive and recognize the taste of the food. This interpretation is what gives us the ability to enjoy and differentiate between different flavors.
In conclusion, the tongue is the organ responsible for the sense of taste. It contains taste buds that detect different taste sensations and sends signals to the brain for interpretation.

Function of Ears
Ears are primarily used for hearing sounds and maintaining balance. The ear is a complex organ that consists of three main parts: the outer ear, the middle ear, and the inner ear.

Hearing
The outer ear collects sound waves and directs them into the ear canal. These sound waves then travel to the middle ear, where they cause the eardrum to vibrate. The vibrations are transmitted through three tiny bones in the middle ear to the cochlea in the inner ear. The cochlea converts these vibrations into electrical signals that are sent to the brain, allowing us to perceive and interpret sounds.

Maintaining Balance
In addition to hearing, the ear also plays a crucial role in maintaining balance. The inner ear contains the vestibular system, which includes the semicircular canals and otolithic organs. These structures detect changes in head position and movement, sending signals to the brain to help us stay upright and stable.

Conclusion
In conclusion, ears are essential for both hearing and balance. They allow us to perceive the world around us through sound and help us navigate our environment safely. It is important to take care of our ears to ensure optimal hearing and balance function.

Importance of taking care of our sense organ

Our sense organs are responsible for providing us with information about the world around us. They allow us to see, hear, smell, taste, and touch, and without them, we would be unable to navigate our environment properly. It is, therefore, critical that we take care of our sense organs to ensure that they continue to function optimally.

The answer to the given question is 'A' - sense. Here are some reasons why we need to take care of our sense organs, particularly our senses:

3. Our senses are interconnected: Our senses are interconnected, and taking care of one sense organ can have a positive impact on another. For example, regularly eating foods that are good for our eyes can also benefit our skin and overall health.

4. Our senses can be damaged: Our senses can be damaged by a variety of factors, including age, illness, injury, and exposure to toxins. Taking care of our senses can help prevent or reduce the risk of damage, and may even slow down the aging process.

5. Our senses affect our mental health: Our senses can also have an impact on our mental health. For example, hearing loss can lead to social isolation and depression, while regular exposure to nature and sunlight can boost our mood and reduce stress.

In conclusion, taking care of our sense organs is essential for maintaining our overall health and wellbeing. By doing so, we can enjoy life to the fullest and navigate our environment safely and confidently.

**The Organ for the Sense of Smell is the Nose**

The sense of smell, also known as olfaction, is a crucial sense that allows us to detect and identify various odors in our environment. The organ responsible for this sense is the nose. Let's explore why the nose is the organ for the sense of smell in detail.

**Structure of the Nose**

The nose is located in the middle of the face and consists of several parts that work together to facilitate the sense of smell:

1. **Nostrils**: These are the openings in the nose through which air enters.
2. **Nasal Cavity**: The nostrils lead to the nasal cavity, which is a hollow space lined with specialized cells called olfactory receptors.
3. **Olfactory Receptors**: These receptor cells are responsible for detecting and transmitting information about odors to the brain.
4. **Nasal Septum**: This is a wall of cartilage and bone that divides the nasal cavity into two halves.
5. **Mucus and Cilia**: The nasal cavity is lined with a layer of mucus and tiny hair-like structures called cilia. These help to trap particles in the air and filter them before they reach the olfactory receptors.

**The Process of Smelling**

When we encounter an odor, the following process takes place:

1. **Inhalation**: As we breathe in, air enters through the nostrils and travels into the nasal cavity.
2. **Odor Detection**: The molecules of the odorant (substance that produces the smell) dissolve in the mucus lining the nasal cavity.
3. **Olfactory Receptors Activation**: The dissolved odorant molecules bind to specific olfactory receptors, which are specialized proteins on the surface of the olfactory receptor cells.
4. **Transmission of Signals**: When the olfactory receptors are activated, they send electrical signals to the olfactory bulb, which is part of the brain.
5. **Interpretation by the Brain**: The olfactory bulb processes the signals and sends them to the brain's olfactory cortex for interpretation. This allows us to recognize and differentiate various smells.

**Conclusion**

In conclusion, the nose is the organ responsible for the sense of smell. Its structure, including the nostrils, nasal cavity, olfactory receptors, and associated mucus and cilia, enables us to detect and interpret different odors. Through the process of smelling, the nose plays a crucial role in our ability to experience and identify the smells around us.
