Research study show that sea urchins displayed similarity with humans like having an immune system and genetic material (DNA). Both belong to the deuterostomes. These animals are similar based on their early stage of development specifically during the embryos form.
Answer:
The correct option is d. Metabolic specificity
.
Explanation:
The specificity principle says that we must train the physical qualities (physiological elements involved) in the concrete conditions that the competition demands. Accordingly, the impact on muscles and metabolic pathways not used directly during exercise is very small. Metabolic specificity is a principle of adaptation and it applies to the energy systems mobilized during the exercise. The muscle mass involved and the overall intensity of the exercise will dictate whether the responses to training will be limited to adaptations at the muscular level or if adaptations will occur at the cardiovascular level. Continuous aerobic training of submaximal intensity is reflected in the increase in the activity of oxidative metabolism enzymes. The running speed of a marathon is regulated by aerobic metabolism in the recruited muscle fibers and by the economic conversion of this energy into speed. Increasing the distance and time of her races progressively allows the endurance athlete to exercise at a high intensity for significantly longer periods of time.
Is there a list to chose from or are you just looking for them all
The changing quantities in an experiment are called variables. A variable refers to any trait, factor, or a condition, which can prevail in distinct amounts or kinds. An experiment generally exhibits three kinds of variables: independent, dependent, and controlled.
The independent variable refers to the one, which is modified. On the other hand, the dependent variable is implied to observe that how it reacts with the change made to the independent variable. The controlled variables refer to the quantities, which one wants to remain constant.
In the given case, that is, heating a cup of water to witness that whether the sugar will get more easily dissolve. In this, the independent variable refers to the temperature of the water determined in degrees Centigrade. The dependent variable refers to the amount of sugar, which dissolves completely measured in grams.
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
Answer:
Grain, species etc..
Explanation:
They were originally used to grind grain or spices or pump water and sawing wood. Now modern windmills are used for electricity.
