Which ecosystem service would suffer from the opening of a mineral mine along a small mountain range?
andreyandreev [35.5K]

Answer:

D. Supporting

Explanation:

Ecosystem services include provisioning, regulating, culture and supporting services.

Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.

Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.

Hence, the correct answer is "D. supporting".

Which hypothesis helps to explain why all organisms share the same genetic code?
KonstantinChe [14]

Answer:

There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.

Explanation:

The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.

How the structure of DNA determines the structure of proteins?
Kruka [31]

Answer:

DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

the nurse completes dietary teaching with a client who has chronic kidney failure. the nurse determines more teaching is needed
VashaNatasha [74]

Answer:

The options

"I will eat more oranges and other foods with vitamin C."

"I should increase dairy products in my diet."

"I should add protein powder to my fruit smoothies."

The CORRECT ANSWER IS

"I will eat more oranges and other foods with vitamin C."

Explanation:

"I will eat more oranges and other foods with vitamin C."

Citrus fruits are rich in potassium and should be stayed away from, since kidneys find it difficult to remove the excess potassium. Examples of foods that are rich in potassium are dried fruits, avocado, tomato, potatoes, and bananas. This statement indicates that additional teaching is needed.

In kidney failure, the client stands a higer chance for hyperkalemia, hypernatremia, and hyperphosphatemia.

Potassium, is found in large amounts in citrus fruits and dried fruits, and there's need to take these fruits with caution.

Phosphorus is limited due to the important balance of potassium electrolyte with calcium. Protein is inhibited as the failure to remove uric acid, which is produced during protein metabolism, via the kidneys. Sodium, obtained in foods, is also restrained to avoid fluid overload and edema.
