Answer:

D) the fact that it is moving water

Explanation:

Water molecules form crystals while they freeze. Na + and Cl- ions of the salt are in the path of the water molecules, making it difficult to rearrange them in crystals. This means that the salt water of the ocean remains in the liquid state for longer when the temperature decreases.

For salt water to freeze, the temperature needs to be well below the melting temperature of pure water which is zero degrees Celsius (0 ° C). In addition, the volume of water in the ocean decreases chances of freezing and sunlight at the equator decreases the freezing point and increases the boiling point.

However, the movement of ocean waters does not interfere with the freezing of these waters.

Was it beneficial or harmful for the Balanus barnacle to add the Chthamalus barnacle? Explain
densk [106]

Answer:

harmful. (more info below)

Explanation:

Balanus may compete with Chthamalus through crowding or smothering, but Chthamalus can inhabit higher tide levels than Balanus since it is more immune to desiccation. Lower on the sea, the barnacles of acorn combine with the Endoclades (Turfweed) assemblage, and are also abundant on the shells of acorn. To conclude, it was a bad idea is add the balanus barnacle to the Chthamalus barnacle becuase balanus barnacles can crowd Chthamalus barnacle.

hope this helped!

Which of these are the claims of pseudoscience most likely based on?
grandymaker [24]

Answer:

Creative imagination

Explanation:

A good scientist is creative or imaginative when it comes to thinking about solving new problems but this solutions come about as a result of getting facts, experiments, and logical information.

But when it comes to pseudoscience, pseudoscientists are imaginative by not basing their explanation in science but otherwise using information that involves their personal experiences and opinions since they do not utilize scientific methods.

1. List and describe three factors that could possibly affect enzyme activity. 2. Why is it important that cells contain catalas
marta [7]

Answer:

1. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). It catalyzes the decomposition of hydrogen peroxide to water and oxygen.

3. Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. ... Extreme pH values can cause enzymes to denature.

4. Enzymes are biocatalysts and because of their remarkable properties, they are extensively used in medical diagnosis. ... They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy. There are lots of enzymes released in the small intestine and from the nearby pancreas for digestion.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.

Explanation:

1. Factors Affecting Enzyme Activity

Knowledge of basic enzyme kinetic theory is important in enzyme analysis in order both to understand the basic enzymatic mechanism and to select a method for enzyme analysis. The conditions selected to measure the activity of an enzyme would not be the same as those selected to measure the concentration of its substrate. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).

4. for clinical applications. Enzymes are the preferred markers in various disease states such as myocardial infarction, jaundice, pancreatitis, cancer, neurodegenerative disorders, etc. They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. Amylase. Amylase is a digestive enzyme that acts on starch in food, breaking it down into smaller carbohydrate molecules. ... First, salivary glands in your mouth make salivary amylase, which begins the digestive process by breaking down starch when you chew your food, converting it into maltose, a smaller carbohydrate.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.
