Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.What does this information best demonstrate?

what are the two factors that create the difference between the temperate forest biome in the taiga biome

Answers

The two factors that create the difference between the temperate forest biome and the taiga biome are as follows:

  • Temperature.
  • Precipitation.

What is a biome?

A biome may be characterized as a very large ecosystem that is consistently running in nature in an unmanaged way. In more simple words, it is defined as a very large area that is characterized by a particular type of vegetation. Some examples of biome may include tropical rainforests, coral reefs, grasslands, etc.

Taiga biomes are generally thick forests. Coniferous trees, such as spruce, pine, and fir, are common. These trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones.

While temperate forests have deciduous trees which lose their leaves in winter, conifers never lose their needles. All such differences are created by numerous factors but temperature and precipitation are the most potent ones.

Therefore, temperature and precipitation are the two factors that create the difference between the temperate forest biome and the taiga biome.

The temperate forest biome covers latitudes ranging approximately from the southern United States to southern Canada, while the taiga biome, also known as boreal forest, extends from the latitude of southern Canada to about 60 degrees north latitude. (see References 1, References 3) Thus, these two biomes are adjacent, which explains the many similarities between taiga and northern temperate forests. Both biomes have four distinct seasons, but the temperate forest climates cover a much wider range of temperatures and precipitation patterns. Taiga, in contrast, is reliably cold: most of the precipitation falls as snow, winters are severe and the growing season is short -- about 130 days compared to 140 to 200 days for temperate forests.

Answers

Answer:

DNA - Deoxyribonucleic acid, a macro molecule which has all the hereditary data or information in many living beings.

Function- DNA plays an important role in the production of proteins, along with the metabolism, and reproduction of the cells.

  • Components- Deoxyribose sugar,
  • A phosphate,
  • A nitrogenous base.( adenine, guanine, thymine and cytosine)

Explanation:

Structure of DNA:

  • The image is a simplified representation of a short DNA molecule, with deoxyribose sugar molecules in orange, linked to phosphate molecules through a special type of covalent linkage called the phosphodiester bond.
  • Each nitrogenous base is represented by a different color – thymine in purple, adenine in green, cytosine in red and guanine in blue.
  • The bases from each strand form hydrogen bonds with one another, stabilizing the double-stranded structure.
