Answer:
The time between the end of ventricular systole to the beginning of atrial systole is 100 ms or 0.1 seconds.
Explanation:
Ventricular systole is the removal of blood from the heart by pumping through aorta and pulmonary vein. Both aorta and pulmonary vein receive the blood from the heart. Aorta receives oxygenated blood and pulmonary vein receive deoxygenated blood, while atrial systole is the addition of blood into the ventricular from vena cava and pulmonary artery due to contraction of heart. This process occurs in 100 ms.
<span>Along North American coasts, the algae responsible for formation of kelp-beds is Brown Algae. The brown algae (such as seaweed) forms an important part of the ecosystem in marine environments as both a food source and habitat. The formation and structure of the brown algae varies from environment, kelp beds and forests are harvested for human consumption.</span>
Climate is best described as C. THE LONG-TERM AVERAGE OF WEATHER VARIATIONS IN A SPECIFIC AREA.
The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.
Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.
Climate are classified into three groups. These are Bergeron and Spatial Synoptic, Koppen, and Thornthwaite.
Answer:
C) convergent evolution
Explanation:
Convergent evolution is a type of pattern of evolution which occurs when the two unrelated species evolves with the same feature or traits as a result of the exposure of the species to the same environmental conditions.
This type of evolution results in ion the formation of the analogous structure which is functionally similar but is evolved from the same ancestor.
In the given question, since the two unrelated species: plants and animals exhibit the same appearance on different geographical areas thus represents that convergent evolution is taking place.
Thus, C) convergent evolution is the correct answer.
