To determine the gametes produced by the pea plants with the genotype RRGg, we need to consider the possible combinations of alleles.
The genotype RRGg can produce four types of gametes:
• RG (round and green)
• Rg (round and yellow)
• rG (wrinkled and green)
• rg (wrinkled and yellow)
Now, let’s consider the cross between two pea plants (RRGg × RRGg):
(a) Gametes having both the round and yellow seed traits (Rg): 25%
(b) Offspring having the same genotype as the parents (RRGg): 50%
(c) Offspring having the same phenotype as the parents (round and green): 75%
Explanation:
(a) The RRGg plants can produce four types of gametes in equal proportions (25% each). One of these gametes is Rg, which represents 25% of the total possible gametes.
(b) In the F1 generation, the possible genotypes are RR, Rg, RG, and gg. The RRGg genotype is 50% of the total possible genotypes.
(c) The phenotype is determined by the physical expression of the traits. In this case, the round and green phenotype is expressed by the genotypes RR and RRGg. The sum of these genotypes is 75% of the total possible phenotypes in the F1 generation.
(a) The fact that a metal X is obtained from its chloride salt by exposure to sunlight suggests that the metal X is likely to be placed towards the top of the reactivity series of metals.

(a) The fact that a metal X is obtained from its chloride salt by exposure to sunlight suggests that the metal X is likely to be placed towards the top of the reactivity series of metals. Metals towards the top of the reactivity series are more reactive, and they often require more energetic methods (such as exposure to sunlight or heat) to extract them from their compounds.
(b) The type of reaction that the chloride salt of metal X undergoes on exposure to sunlight is likely to be a photochemical reaction. Photochemical reactions involve the absorption of light energy to bring about a chemical change. In this case, exposure to sunlight induces a reaction in the chloride salt, leading to the formation of the metal X.
(a) Compound P, with six carbon atoms and twelve hydrogen atoms, can be identified as a saturated hydrocarbon. In saturated hydrocarbons, all carbon-carbon bonds are single bonds, and the molecule is "saturated" with hydrogen atoms. This is because each carbon atom forms four single bonds, reachingRead more
(a) Compound P, with six carbon atoms and twelve hydrogen atoms, can be identified as a saturated hydrocarbon. In saturated hydrocarbons, all carbon-carbon bonds are single bonds, and the molecule is “saturated” with hydrogen atoms. This is because each carbon atom forms four single bonds, reaching its maximum valency. In the given compound P, if it only contains single bonds, it is saturated.
(b) To determine if compound P is saturated or unsaturated, a common test is the bromine water test. Bromine water is an orange solution, and in the presence of an unsaturated compound, it undergoes decolorization. If compound P is unsaturated (contains double or triple bonds), it will react with bromine water, causing the orange color to fade.
(c) When compound P is burned in excess air (complete combustion), it reacts with oxygen to form carbon dioxide (CO2) and water (H2O). The balanced chemical equation for the combustion of a hydrocarbon can be represented as follows:
Compound P + O2 → CO2 + H2O
In this case, since the specific structure of compound P is not provided, the general formula CnH2n+2 for saturated hydrocarbons can be used for illustrative purposes. The combustion products will be carbon dioxide and water.

(a) Budding:
Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud on the parent organism. The bud grows into a mature individual, eventually detaching from the parent. This process is similar to stem cells in the sense that a specialized structure (bud or stem cell) has the potential to develop into a complete, functional organism or cell type.
Regeneration:
Regeneration is the ability of an organism to regrow lost or damaged body parts. In multicellular organisms, certain cells, often referred to as regenerative cells, have the ability to divide and differentiate to replace damaged tissues. This process is akin to the ability of stem cells to differentiate into various cell types for the regeneration and repair of tissues.

Testes and Ovaries:
Justification: The testes in males and ovaries in females are both reproductive organs responsible for producing gametes (sperm and eggs, respectively). They are functionally similar as they are involved in the process of gametogenesis. Additionally, both organs produce hormones (testosterone in males and estrogen/progesterone in females) that play crucial roles in the development and maintenance of reproductive structures and secondary sexual characteristics.
Penis and Clitoris:
Justification: The penis in males and the clitoris in females are homologous structures derived from the same embryonic tissue. Both structures are involved in sexual arousal and contribute to the reproductive process. They contain erectile tissues and are sensitive to stimulation. While the functions are not identical, they share a common embryonic origin and have analogous roles in sexual response.
