Answer:Hola! my name is marissa and im here to help!

Explanation:

a hydrophyte is a plant that thrives only in or on water, such as the common lilly pad while a xerotype is a plant that makes adaptations to survive with very little water such as a cactus

Outline three examples of cycles of inorganic nutrients. For each, outline the uses of the nutrients in living organisms, its me

Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.

using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene

rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Answer:

Hyphae: Cell filaments,mostly septate

Mycelium: Mass of hyphae

Molds: mostly filamentous, Yeasts: non-filamentous,unicellular fungi

Budding yeasts divide asymmetrically.

Dimorphic fungi: yeast-like at 37°C, mold-like at 25°C.

Fungal spores are reproductive spores (unlike bacterial spores). Used to differentiate fungi.

Growth in acidic, low-moisture, high osmotic pressure environments.

The thallus (body) of a mold or fleshy fungus consists of long filaments of cells joined together; these filaments are called hyphae. Hyphae can grow to immense proportions. The hyphae of a single fungus in Oregon extend across 3.5 miles.

In most molds, the hyphae contain cross-walls called septa (singular: septum), which divide them into distinct, uninucleate (one-nucleus) cell-like units. These hyphae are called septate hyphae. In a few classes of fungi, the hyphae contain no septa and appear as long, continuous cells with many nuclei. These are called coenocytic hyphae. Even in fungi with septate hyphae, there are usually openings in the septa that make the cytoplasm of adjacent "cells" continuous; these fungi are actually coenocytic organisms, too.

Mycelium a mass of long filaments of cells that bring and intertwine, typically found in molds.
