Mashcka [7]3 years ago

The correct answer is False

Explanation:

In biology, bacteria are unicellular and prokaryotic organisms as they do not contain a nucleus. Bacteria are mainly characterized by their simple structure, the capability to survive in almost any environment and small size.

In terms of discovery, bacteria were unknown for many centuries; however, this changed in the 17th century as the Dutch scientist Van Leeuwenhoek designed a microscope and was able to observe a bacteria for the first time in 1676. This also led to subsequent studies and in this way nowadays there is a lot of information about this type of microorganism. According to this, it is false scientists discovered bacteria for the first time in the 1920s as bacteria were discovered in 1676.

Describe ways that a human society's culture, agricultural practices, and health practices would be shaped by living in an area
Pachacha [2.7K]

Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

<h3>What are active volcanoes?</h3>

Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.

These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.

Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.

In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon
stellarik [79]

Answer:

  1. Glycine
  2. Ribulose 1,5-bisphosphate
  3. 3-phosphoglycerate
  4. Glyceraldehyde 3-phosphate.
  5. Glucose
  6. Sucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

<u>Calvin cycle</u>

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

<u>Cytosol: </u>

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.
