Answer:

A) The production of energy without the presence of oxygen  - Anaerobic respiration

B) The chemical breakdown of a substance  - Fermentation

C) The breakdown of food to create energy in the presence of oxygen  - Aerobic respiration

D) An organic molecule that occurs as an intermediate in many metabolic processes - Pyruvate

Explanation:

A) Anaerobic respiration is a type of cellular energy production that occurs in the absence of oxygen. it is much less efficient than aerobic respiration (see question C). In cellular respiration, cells produce ATP, which is the "currency" of energy in the cell, by breaking down glucose. ATP is required to carry out the normal functions of a cell.

As it is much less efficient than aerobic respiration, it produces much less ATP. However, when there is no oxygen, it is the only choice. An example is when muscle cells are working very hard and use up all the oxygen in the tissue. To keep producing some energy, they undergo anaerobic respiration, which only produces 2 molecules of ATP for every molecule of glucose.

B) In respiration, Fermentation is a pathway of breaking down glucose into chemical energy that occurs in the absence of oxygen. Anaerobic respiration can lead to two types of fermentation, lactic acid fermentation (described above) and ethanol fermentation which is another type of anaerobic respiration in which fungi (such as yeast) break down glucose into ethanol, producing 2 molecules of ATP carbon dioxide as a by-product. This is how we make bread and beer!

C) Aerobic respiration is cellular respiration in the presence of oxygen. It creates a net gain of 36 molecules of ATP, compared to the 2 ATPs created without oxygen. This is because in aerobic respiration, the oxygen acts as a final electron acceptor for the electron transport chain. In its absence the electron transport chain cannot proceed. The electron transport chain is how cells generate most of their chemical energy.

D) Pyruvate is an important molecule in the process of respiration. Both aerobic and anaerobic respiration begin with the same process, glycolysis. Glycolysis is the process by which 1 molecule of glucose is broken down into two molecules of pyruvate - a metabolic intermediate. This releases 2 molecules of ATP. In the presence of oxygen, pyruvate is oxidised and enters the Krebs cycle, which makes a series of compounds that donate electrons to the electron transport chain, which produces extra ATPs through oxidative phosphorylation.

In the absence of oxygen, pyruvate is converted either to lactic acid or ethanol by fermentation

The development of septa in the hyphae of fungi was an important evolutionary step. why?
Semmy [17]
Because if a hypha is damaged, fungi can seal septa pores to prevent cytoplasmic leakage.

1) Research the history of terrariums. Find out who developed the first terrarium. What did this particular scientist want to st
dedylja [7]
1 ) The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.

2 ) <span />Because of the different conditions within, terrariums there are two, which can be classified as closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.​

Sorry working on this right now as well, and I don't have the others yet :(

Which tissue is correctly paired with its primary cell type?
sattari [20]

<em>Full Question:</em>

<em>Which tissue is correctly paired with its primary cell type?</em>

<em>bone: fibrocyte</em>

<em>bone: osteoblast</em>

<em>connective tissue proper: chondroblast</em>

<em>cartilage: fibroblast</em>

Explanation:

<em> </em><u><em>bone: osteoblast</em></u>

<u><em></em></u>

<u><em></em></u>

Osteoids comprise, significant sections of the entire bone matrix, and  this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.

Osteoblasts are highly specialized cells within bone which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification (fortification with allium) of osteoid during the formation of mature bone matrix.
