I need to know the hypothesized enzyme
worty [1.4K]

Answer:

Hypotheis:

<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>

  • <u>A- Pepsin</u>
  • <u>B- Amylase </u>
  • <u> C- thermophilic enzyme</u>

Explanation:

Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.

Each enzyme provided has its own optimal temperature and pH values.

  • Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
  • Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4  glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
  • Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH  is typically low i.e. acidic due to the hydrochloric acid in digestive juices.

Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.

Put the last 6 (Creep to Avalanche) in order from Fastest to Slowest.
kompoz [17]

Answer:

creep, solifluction, slump, earthflow, mudflow, debris avalanche, rockfall

Explanation:

Mass movement also known mass wasting is the motion of rock,  regolith (loose mixture of soil and rock particles that covers the earth's surface), snow, and ice down a slope. Based on increasing speed of movement, the given mass movement processes are as follows:

Creep- this a very slow, usually continuous movement of regolith down slope.

Solifluction - this is a sediment flow. A sediment flow is a mixture of rock, regolith with some water. The rate solifluction is measured in centimeters per year. It occurs at a faster rate than than creep.

Slumps - is a type of mass movement whereby there is a downward rotation of rock or regolith along a curved surface producing depressions or scars on the slope. It occurs at a faster rate than solifluction.

Earthflows - they usually occur with heavy rains and occur at a much faster rate with velocities between several centimeters per year and hundreds of meters per day.

Mudflows- are a highly fluid mixture of sediment and water which usually result from heavy rains in areas where there is an abundance of loose sediment. These sediments are picked up by flowing streams of water. Mudflows occur at high velocities and can travel long distances.

Debris Avalanches - These are very high velocity mass movements that result from the complete collapse of a mountainous slope. Earthquakes and volcanic eruptions usually cause debris avalanches. Avalanches involving snow only is known as snow avalanches.

Rock Falls - Rock falls occur when a piece of rock which may be large or small on a steep slope comes loose and falls down the slope. On its way down it may dislodge other rocks which also fall down the slope. Rock falls are the fastest of the six types of mass movements stated.

Assuming that other factors are equal, how are the birthrate and death rate
igor_vitrenko [27]

Answer:

In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.

Explanation:

The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.

In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.
