Answer:
Protists were traditionally subdivided into several groups based on their physical similarities to the "higher" kingdoms of Animals, Plants, and Fungi. For example, the unicellular, “animal-like” protozoa, the “plant-like” algae, and the “fungus-like” slime molds and water molds are all protists.
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities. In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.
Answer:
The correct answer is A) An image indicating the shape of a DNA molecule. See the explanation below, please
Explanation:
Rosalind Franklin through studies of X-ray diffraction and crystallography, showed the double helix structure of the DNA molecule.
Answer:
Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.
Explanation:
Water shed are of different types-
- Large water sheds-Contain well developed channel networks.
- Small water sheds-Contain dominant land phase.
- Urban watershed-It is dominated by building,roads,pavements.
- Agriculture water shed-
- Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
- Mountain water shed-mountain is the dominant component that separates the water flow.
- Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
- Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.
This statement is true. Early land animals indeed had gills as well as lungs. It is generally known that amphibians breathe through their skin, like how the lungs needed the skin for its respiratory. Fish have gills for breathing while mammals do have their nasal cavity and lungs for their gas exchange.
