The nature-nurture phrase was given by English Victorian Polymath Galton in a discussion of the influence of hereditary and environment in social advancement. The nature-nurture debate involves whether a person's behavior is a product of the environment, or it is inherited. Some say that the person's behavior is a product of his surroundings while others argue that the person's behavior is a product of genetics.
Hence, the correct answer is, 'Genetics and Environment.'

The image in a plane mirror forms virtual and erect image and appears to be as far behind the mirror as the object is in front of the mirror. A diverging lens or a convex mirror forms a virtual image.A virtual image is produced by a concave mirror when the object is placed inside the focal length of the mirror.

Sodium hydroxide, also known as caustic soda, is one of the compounds that can be created from common salt, sodium chloride (NaCl). It is a strong base with various industrial and household applications, including in soap making, paper production, and water treatment.

The forebrain is the region of the brain associated with hunger and the integration of sensory impulses from various parts of the body. It is considered the most complex and specialized part of the brain, housing the cerebrum, which plays a crucial role in thinking, voluntary actions, memory storage, and sensory integration.

Excretion is the biological process involved in the removal of harmful metabolic wastes from the body. It is essential for maintaining internal balance and ensuring the proper functioning of various bodily systems. Through excretion, organisms eliminate waste products such as urea, ammonia, and carbon dioxide, which are byproducts of metabolic processes. This process helps in preventing the accumulation of toxic substances in the body, ensuring overall health and well-being.

Law of Triad was proposed by Dobereiner.
Detailed
The Law of Triad was proposed by Johann Wolfgang Dobereiner, a German chemist, in the early 19th century. This law was one of the earliest attempts to organize the elements based on their chemical properties and atomic weights.
Key Points:
- The Law of Triad states that when elements are arranged in order of their increasing atomic weights, the middle element in a triad has properties that are an average of the other two elements.
- Dobereiner observed that certain groups of three elements showed similar chemical properties and their atomic weights had a specific relationship.
- One example of a triad is calcium (Ca), strontium (Sr), and barium (Ba). Calcium has an atomic weight of 40, strontium has an atomic weight of 88, and barium has an atomic weight of 137. The atomic weight of strontium is the average of calcium and barium. These elements also exhibit similar chemical properties.
- Dobereiner identified several other triads, such as chlorine (Cl), bromine (Br), and iodine (I), and lithium (Li), sodium (Na), and potassium (K).
- The Law of Triad provided the basis for the development of the periodic table by other chemists, such as Dmitri Mendeleev.
- However, the Law of Triad had limitations and was not applicable to all elements. It could only explain the properties of a few groups of elements.
Overall, Dobereiner's Law of Triad was an important early contribution to the understanding of the periodic table and the relationships between elements based on their atomic weights and chemical properties.

According to his experiment, Rutherford conclusion given below,
Rutherford's first conclusion is that the nucleus is smaller than the atom and second is that inside the atom electrons and nucleus are present. In the atom electrons revolve around the nucleus and rotate itself. The mass of the atom depends on the nucleus. The nucleus only has the maximum mass of the atom. The charge of the nucleus is positive and the charge of electrons is negative.

The nucleus of an atom contains:
The nucleus of an atom is the central part of an atom that contains most of its mass. It is composed of subatomic particles called protons and neutrons. Here is a detailed explanation of the components of the nucleus:
1. Protons:
- Protons are positively charged subatomic particles.
- They have a mass of approximately 1 atomic mass unit (amu).
- The number of protons in an atom determines its atomic number and defines the element.
2. Neutrons:
- Neutrons are neutral subatomic particles.
- They have a mass of approximately 1 amu, similar to protons.
- The number of neutrons in an atom can vary, resulting in different isotopes of an element.
3. Electrons:
- Electrons are negatively charged subatomic particles.
- While electrons are not present in the nucleus, they occupy the region surrounding the nucleus, called electron shells or energy levels.
- The number of electrons in an atom is equal to the number of protons, ensuring overall charge neutrality.
Summary:
The nucleus of an atom contains protons and neutrons, while electrons are found in the electron shells surrounding the nucleus. Therefore, the correct answer is option C: Neutrons and Protons.

 The correct answer is a

   Archimedes' principle, a physical law of buoyancy, states that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force the magnitude of which is equal to the weight of the fluid displaced by the body.

There is no change to the image distance in the eye when we increase the distance of an object from the eye.

To see closer or distant objects clearly, the eyes, due to their accommodation, can increase or decrease the focal length of its lens, by contraction and relaxation of ciliary muscles, so that the image is always formed at the retina.
