Answer:
The correct answer is option d. "All of the above".
Explanation:
A hypothesis is a proposed explanation, based on the evidence that is at hand, for a set of observations and looking for further investigations. A hypothesis in an economic model works under the same premise that a hypothesis in a scientific investigation. The hypothesis may be correct or incorrect, therefore it should be tested before it can accepted only if the results show that the hypothesis explains all the obtained explanations. Regarding economic model hypothesis, usually they deal with causal relationships between an observed phenomena and the origin of it.
C. Radiation and chemotherapy can kill healthy cells
Explanation: radiation causes every cell around where it is put, to die, including healthy. Chemo and radiation don’t know the difference between healthy and unhealthy
Hemorrhagic shock occurs when the body begins to shut down due to large amounts of blood loss. People suffering injuries that involve heavy bleeding may go into hemorrhagic shock if the bleeding isn't stopped immediately. Common causes of hemorrhagic shock include: severe burns
In this type of shock, disruption of the sympathetic nervous system, as occurs in spinal cord or brain injury, causes widespread vasodilation. ... This form of shock results from decreased blood volume, often due to trauma. Inadequate blood returns to the heart, reducing cardiac output and blood pressure.
The obvious cause of hypovolemic shock is blood loss, but that isn't all of it. The loss of blood can come from external or internal bleeding due to illness or injury. Most of the time, hypovolemic shock will be a complication of another condition.
Answer:
The five true statements are numbers: 1, 2, 5, 6 and 7
Explanation:
1. Temperature drives water movement in some lakes.
2. Tropical coral reefs generally exist in relatively shallow areas of the ocean.
5. Wetlands have slow water movement or no water movement and no turnover.
6. Estuaries are very productive and are used as breeding grounds by many species of fish.
7. A freshwater organism permanently attached to the substrate would be unlikely to survive and reproduce in an estuary.
Answer:
This is an example of directional selection.
Explanation:
Directional selection is a type of positive selection where the evolutionary fitness of one genotype is higher compared to the other ones, thereby favoring the selection of one particular phenotype and shifting allele frequencies towards the selected genotype. In a biological context, the directional selection increases the chances for surviving and for reproducing in those organisms that have the alleles favored by this type of selection. Thus, the directional selection produces the loss of genetic variability and leads to the fixation of the dominant alleles.
