how is atmospheric carbon in the form of CO2 converted into a molecule that is usable to all organisms?​
mixas84 [53]

Answer:

The carbon-dioxide exists in the atmosphere, and it is dissolved in the water.

Explanation:

With the process of photosynthesis, it becomes organic, and by breathing, the organic gas goes back to carbon-dioxide.

The assimilation of carbon is the process when the carbon-dioxide converts to organic carbon with the help of living organisms. This organic carbon is then used for energy.

The Steady State Theory state that the density of the universe was remaining constant.

<h3>Steady State Theory:</h3>

In cosmology, a steady-state theory is a perspective that holds that the universe is constantly expanding while maintaining a constant average density. According to this theory, the matter is continuously created to form new stars and galaxies at the same rate that older ones fade away due to their expanding distance and accelerating recession. The average density and configuration of galaxies are the same as any location in a steady-state universe, which has no beginning or end in time.

British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle first proposed the hypothesis in 1948. Hoyle expanded on it in order to address issues that had come up in relation to the alternative big-bang theory. According to the hypothesis, in order to maintain a constant average density of matter across time, the new matter must constantly be created, primarily as hydrogen. With nearly five times as much dark matter, the amount needed is small and not immediately observable: one solar mass of baryons per cubic megaparsec every year, or one hydrogen atom per cubic meter every billion years.

A gene cannot react chemically and form a trait without the proper what
kogti [31]

Answer:

Enzyme

Explanation:

Enzymes are the bio-catalyst that serve to accelerate the metabolic reactions occurring in a living cell.  All the metabolic reactions of organisms are catalyzed by enzymes. Each metabolic reaction is catalyzed by specific enzyme. Absence of that particular enzyme leads to absence of the respective product. Since genes code for protein which regulate the specific trait, absence of enzyme does not allow the expression of that trait.

Example: Absence of enzymes for chlorophyll synthesis would lead to absence of chlorophyll from leaves of the green plants.

~~9. what are the haploid reproductive structures of fungi called? (1 point)
Katarina [22]
The correct answer is the spores. Fungi reproduce asexually by budding, fragmentation, or spore production. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte.
