Answer:

Its c ,animals ,seed wings and wind

Explanation:

There are mainly 2 ways the seeds of gymnosperms are dispersed :-

  1. The gymnosperms that are old become rip and their cones open up and the seeds are dispersed by the wind.There are small seed wings present on seeds that take the seed to long distance places
  2. The fruit of the gymnosperms gets eaten by the animals in different places as its their source of food .The seeds are not digested by the animals and excreted as a result the seed is dispersed far away from the source

What is a triacylglycerol ? Discuss the advantages of organisms having triacylglycerol as energy storage molecule?
Sergeeva-Olga [200]

Answer:

Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.

Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.

Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.

Thiobacillus denitrificans is a species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as
tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
