Correct Answer: B. Glucose and oxygen

Explanation

The primary products of photosynthesis are glucose and oxygen. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose, a simple sugar that serves as the main source of energy for the plant. Oxygen is also produced as a byproduct of photosynthesis and is released into the atmosphere.

Correct Answer: C) Aquatic habitat

Explanation

You are being asked to choose from a list of options that groups together different types of bodies of water. The bodies of water listed are puddles, ponds, rivers, seas and oceans. You are asked to select which option groups them together correctly. Option A, Ecosystem, refers to a community of living and non-living things that interact with each other in a particular environment. Option B, Biosphere, refers to the part of the earth where living things exist. Option D, Terrestrial habitat, refers to land-based habitats. Option C, Aquatic habitat, is the correct answer. This option groups together bodies of water such as puddles, ponds, rivers, seas and oceans. Aquatic habitats are habitats that are found in water, and can be further classified as either freshwater or marine habitats. Freshwater habitats include ponds, lakes, rivers, and wetlands, while marine habitats include oceans, seas, coral reefs, and estuaries. It is important to note that aquatic habitats are home to various types of organisms, such as fish, algae, and plankton. In conclusion, the correct option that groups together puddles, ponds, rivers, seas and oceans is Option C, Aquatic habitat.

Correct Answer: C) Testis

Explanation

In the female reproductive system, the ovary plays an important role. It is responsible for producing eggs that can be fertilized by sperm to form a zygote, which eventually develops into a fetus. Now, the question is asking what structure in the male reproductive system is similar to the ovary in the female reproductive system. The correct answer is Option C: Testis. The testis is the male reproductive organ that produces sperm cells. Just like the ovary, it is a vital part of the reproductive system because it produces the gametes (sperm cells) that are necessary for fertilization. Option A (Penis) is incorrect as it is not an organ responsible for producing gametes like the testis and ovary. The penis is an external organ that serves as a conduit for urine and semen. Option B (Urethra) is also incorrect as it is a tube that carries urine and semen out of the body and does not produce gametes. Option D (Cowper's gland) and Option E (Prostate gland) are also incorrect as they are accessory glands that produce fluids that mix with sperm to form semen, but they do not produce gametes. In summary, the testis is similar to the ovary in the female reproductive system as they both produce gametes necessary for fertilization.
