First law of thermodynamics is based on law of conservation of energy i.e. energy supplied to a system has to be used in raising the internal energy of the system. So heat supplied is used to carry out the process.
∆U = Q + W.

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.

Interference occurs for both transverse and longitudinal waves.
Interference does not indicate whether light is transverse or longitudinal since interference occurs for both types of waves.

Van de Graff generator- is an electrostatic generator which is devised to produce very high voltage by means of an endless belt collecting electrostatic charge from a source and transferring it to a large isolated metal sphere on which a large change accumulates.

The substance which take part in reaction is called reactants and the substance which formed after the reaction is called products.

As from law of conservation of mass:-mass of reactants=mass of product Therefore, mass of compound A + mass of compound B=mass of compound C So, 5g + 10g= 15g

The brown ring test is used to determine the presence of nitrate ions, NO₃^–. Dilute ferrous sulfate solution is added to solution containing nitrate ion. Following this, concentrated sulfuric acid is added along the sides of the test tube. A brown ring is formed at the junction concentrated sulfuric acid and solutions.

Rusting of iron is an example of oxidation as iron loses electrons to form iron oxide (rust).

The acid present in the body of a red ant is formic acid. Formic acid is also known as methanoic acid, and its chemical formula is HCOOH.

The head-on or end to end type of overlapping is present in sigma bond. A sigma bond is a type of covalent bond. It may also be called an axial overlap. In case of the hydrogen molecule, its s-s overlapping.

The atrial natriuretic hormone (ANP) is a cardiac hormone in which genes and receptors are widely present in the body. Its main function is to lower blood pressure and to control electrolyte homeostasis. So the correct option is 'decrease blood pressure'.

Bending of stem towards sunlight is called phototropism.

We have three types of nerves: motor nerves that carry messages from brain or spinal cord to motor organs only, sensory nerves that carry messages from sensory organs to spinal cord or brain only and mixed nerves that carry messages to and from both sides.

Explanation:
To determine which of the options are not nutrients, we need to understand what nutrients are. Nutrients are substances that provide nourishment to the body and are essential for growth, development, and maintenance of bodily functions. They can be divided into six major categories: carbohydrates, proteins, fats, vitamins, minerals, and water.
Let's analyze each option:
Option A: Proteins and carbohydrates
- Proteins and carbohydrates are both essential nutrients.
- They provide energy and play a crucial role in the body's structure, growth, and repair.
Option B: Vitamins and minerals
- Vitamins and minerals are also essential nutrients.
- They are required in small amounts but are crucial for various bodily functions and processes.
Option C: Dal and rice
- Dal and rice are food items and not individual nutrients.
- However, they do contain nutrients such as proteins, carbohydrates, vitamins, and minerals.
Option D: Both A and B
- This option is incorrect because both proteins and carbohydrates (option A) and vitamins and minerals (option B) are indeed nutrients.
Therefore, the correct answer is option C: Dal and rice are not nutrients, but they do contain nutrients.

Developing crop varieties with wider adaptability will help in stabilising crop production, because:
1. A single variety can be grown under different climatic conditions in different regions:
- Crop varieties with wider adaptability can tolerate a range of climatic conditions, including temperature, humidity, and rainfall variations.
- This allows farmers to cultivate the same variety in different regions, reducing the risk of crop failure due to unfavorable weather conditions.
- It provides flexibility in crop production, ensuring a stable supply of food even in regions with unpredictable weather patterns.
2. That variety will have resistance to a wide variety of pests:
- Developing crop varieties with wider adaptability often involves incorporating traits that enhance resistance to various pests and diseases.
- This reduces the reliance on chemical pesticides, resulting in more sustainable and environmentally friendly farming practices.
- By minimizing crop losses due to pests, the stability of crop production is improved, ensuring a consistent supply of food.
3. That variety will be higher yielding than many other varieties:
- Crop varieties with wider adaptability are often selected based on their ability to produce high yields under diverse environmental conditions.
- These varieties are bred to have better stress tolerance, efficient nutrient utilization, and improved growth characteristics.
- Higher-yielding varieties contribute to stable crop production by providing a larger harvest, reducing the risk of food shortages.
4. That variety can be grown under the same climatic conditions:
- Developing crop varieties with wider adaptability also includes selecting varieties that can thrive under similar climatic conditions.
- This allows farmers to grow the same variety continuously without needing to switch to different varieties each season or year.
- Consistency in crop variety simplifies farming practices and reduces the need for constant adjustments, leading to more stable crop production.
In conclusion, developing crop varieties with wider adaptability plays a crucial role in stabilizing crop production. It allows for cultivation under various climatic conditions, provides resistance against pests, enhances yield potential, and simplifies farming practices. These factors collectively contribute to a more reliable and secure food supply.

Precipitation and water runoff feed bodies of surface water. Evaporation and seepage of water into ground, on the other hand , cause of water bodies to lose water. Water that seeps deep into the ground is called groundwater. Surface water and groundwater are  reservoirs that can feed into each other.

The longest bone in our body is the Femur.
Explanation:
- The femur is located in the thigh and extends from the hip to the knee.
- It is the largest and strongest bone in the human body.
- The average length of a femur in an adult is about 18-20 inches (46-51 cm).
- The femur is responsible for supporting the weight of the body, providing stability, and allowing for movement.
- It is crucial for activities such as walking, running, and jumping.
- The femur has a unique structure with a head, neck, shaft, and two condyles at the bottom that articulate with the tibia and patella.
- It is also a site for the attachment of several muscles, including those responsible for hip flexion, extension, and rotation.
- The femur is composed of dense and strong bone tissue, allowing it to withstand significant forces during daily activities.
- In cases of fractures or injuries to the femur, surgical intervention may be necessary to ensure proper healing and restoration of function.

Pyramid of numbers in a forest ecosystem is spindle shaped. In a forest ecosystem, number of producers is lesser but supports a greater number of herbivores. Which in turn support a fewer number of carnivores. This results in spindle shaped structure of pyramid of numbers.

Answer:

The basic unit of classification is the species. Let's break down the answer into heading and HTML bullet points for a more detailed explanation:

Classification:

- Classification is the process of organizing and categorizing living organisms into different groups based on their characteristics and relationships.
- It helps scientists to study and understand the vast diversity of life on Earth.

Linnaean Classification System:

- The Linnaean classification system, developed by Carl Linnaeus in the 18th century, is the most widely used system for classifying living organisms.
- It uses a hierarchical structure, with each level representing a different category of classification.

Levels of Classification:

- The Linnaean system includes several levels of classification, from broad to specific categories.
- The levels, in descending order, are: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
- Each level represents a progressively smaller and more specific group of organisms.

The Basic Unit - Species:

- The species is the most specific and fundamental unit of classification.
- It refers to a group of organisms that share similar characteristics and can interbreed to produce fertile offspring.
- Members of the same species have a high degree of genetic similarity.

Other Levels:

- While genus is a level in the Linnaean system, it is not the basic unit of classification.
- The genus is a broader category that includes closely related species.
- Order is also a level in the Linnaean system, but it is even higher and more inclusive than the genus level.

Summary:

- The basic unit of classification is the species.
- The Linnaean classification system includes various levels, but species is the most specific and fundamental category.
- The species level represents a group of organisms with similar characteristics and the ability to interbreed.

Aquatic animals use gills for respiration. The gills absorb oxygen from the air dissolved in water.

x² + y² - 4x - 6y + 4 = 0

Centre of the ellipse is the intersection point of
