Explanation:
blood flows more slowly in the capillaries than in the aorta. why?
Answer:
because it a smaller part
Explanation:
Due to the capillaries' large overall cross-sectional area, blood flow there is slow, allowing for adequate nutrition exchange.
How blood flows through blood vessels?The rate of blood flow dramatically decreases as it enters arteries, arterioles, and eventually, capillary beds, slowing to roughly 0.026 cm/sec, or 1,000 times slower than the aorta.
The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients. A force that opposes a fluid's flow is called resistance.
The majority of blood vessel resistance is caused by the size of the vessel. Blood flow reduces as vessel diameter shrinks due to an increase in resistance.
Therefore, the high total cross-sectional area capillaries blood flows more slowly.

You hear rumors about an unusual series of four islands in the Tierra del Fuego archipelago of Chile. On these islands, the typical laws of island biogeography theory are reversed such that species colonization rates are influenced by island size, not isolation, and small islands have higher colonization rates than larger islands. In addition, islands close to the mainland have higher extinction rates than islands far from the mainland. Of the four islands in this archipelago, a _____ island _____ the mainland would have the SECOND LOWEST equilibrium number of species.
Of the four islands in this archipelago, a SMALL island CLOSE TO the mainland would have the SECOND LOWEST equilibrium number of species. Biogeography studies species distribution.
Biogeography refers to the discipline that examines the range of distribution of species and taxonomic groups in a given geographical area over geological time.
The theory of island biogeography is a scientific theory that posits the idea that larger islands exhibit a greater amount of species (i.e., higher biodiversity) than smaller islands.
According to this theory (island biogeography), each island represents a particular unique ecosystem, which is different from other surrounding ecosystems.

The G. rabbit is the only primary consumer seen.
Trophic Levels in Food ChainThe food chain is made up of three main groups of living beings:
ProducersConsumers and Decomposers.Each of them represents a trophic level of energy flow transmitted through food. The first trophic level is formed by the producers and the last one is the decomposers.
Primary ConsumersAre all organisms that feed directly on Producers. In this case, they are usually herbivorous or omnivorous animals, as they consume plants.
With this information, we can conclude that in the alternatives, g. rabbit is the only alternative corresponding to a primary consumer.

The type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are _____ fibers.
The type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.
Slow fibers have numerous mitochondria that allow you to obtain large amounts of energy aerobically.
Its contraction speed is slow, providing it with high resistance to fatigue, thus maintaining exercise for hours, typical of endurance sports (marathon).They are able to retain a longer duration of exercise at a more constant pace. These fibers are important for endurance triathletes, those who compete in medium and long distance.Therefore, we can conclude that the type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.

Type the correct answer in the box, Use numerals instead of words.
The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.
Human activities release 9 gigatons of carbon into the atmosphere each year.
Human activities remove 5 gigatons of carbon from the atmosphere each year.
Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.
9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.
A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.
Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).
Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
