Answer:
The correct answer is option b. "it has high face validity".
Explanation:
Face validity in a test is a very broad concept that simply refers to whether the test appears to be suitable to report what it claims to do. It is important to notice that high face validity in a test only means that the judgers of the test agree that the test is suitable, but it doesn't mean that the test is reliable for the patient and for the therapist. In this example, Kristoff should take other tests and examinations before he could be sure that he is not suffering from depression, particularly because he has many symptoms that indicate that he is depressed.
Both Aristotle and Linnaeus classified animals and plants, considering where the species lived. However, Linnaeus delved further into classifying organisms looking at their morphology, with an ordered subset of the organism's class divided into five kingdoms: class, order, species, genus, and variety. The process of this classification is called Taxonomy, however, modern scholars also consider the evolutionary history of a species, in the classification process.
Answer:
d) passage of a solute against its concentration gradient
Explanation:
When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.
If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, the pyramid he or she would use would be the pyramid of numbers. The pyramid of numbers presents the population of organisms (individually) in each trophic level in a certain ecosystem.
The following option are correct:
1. There will be interspecific competition between foxes and tigers.
Competition for food between animals of different species is called interspecific competition while that between the same animal species is called intraspecific competition.
2. The energy received at the tropic level of carnivores will be less than the usual amount.
The energy received at the trophic level become reduced because the amount of food available for the carnivores has been reduced.
3. There will be decreased biomass at the trophic level of carnivores.
Decrease biomass will occur at the trophic level of carnivores because, those carnivores that can not survive the food reduction problem will die off.
