Answer:
Heart will beat 140 times in 2 minutes.
Heart beats at a rate of 70 beats per minute.
Explanation:
In 0 minutes heart beats 700 times
hence in 1 minute it will beat <span><span>70010</span>=70</span> times
and heart will beat 140 times in <span><span>14070</span>=2</span> minutes
Answer:
The answer is Option C: Index fossils.
Explanation:
Index fossils are used to identify geologic periods or faunal stages in rock layers. These fossils must have a wide geographic distribution and manifest obvious evolutionary trends to help geologists and others who need this geological data to better understand the time scale and to pinpoint a time period. For example, ammonites were common during the Mesozoic Era, but they were extinct by the Cretaceous period. Geologists would use ammonites to help determine this time frame if present.
Calhoun was vice president of the United States in 1824 under John Quincy Adams and was re-elected in 1828 under Andrew Jackson. Jackson was for the Tariff of 1828 and caused Calhoun to be opposed to Jackson, which led to Calhoun's resignation in 1832.
The statement that the saturation vapor pressure of the air parcel increases is true among the given statements.
Answer: Option B
<u>Explanation:</u>
The saturation vapor pressure of the air parcel will increase with the increasing temperature. The amount of pressure that each air bubble will exert will increase if the temperature is increased. This would in turn make the vapor molecules saturate just above the water molecules.
This eventually results in precipitation. At high temperature, vapor molecules take less time to saturate over the water as compared to saturation at freezing temperatures which means that rainfall is more when temperature causes saturation vapor pressure to increase.
Answer:
the lithosphere is the solid, rocky crust covering the planet and the hydrosphere is composed of all the water on the planet
Explanation:
The lithosphere and the hydrosphere have numerous similarities, but also numerous differences. The biggest and most obvious difference between these two spheres of planet Earth is that the lithosphere is solid, rocky crust that covers the planet, while the hydrosphere is and is represented by all of the water on the planet. The crust is mostly made up by the volcanic activity, thus through the lava flows and crystallization of the magma, which have created the rocks, or with other words the crust, the land masses. The hydrosphere is represented by the waters, and it has been created by both water coming from the volcanoes, and from the space objects that have been falling on our planet. The waters are generally divided into two categories, saline and freshwater, with the saline being in much higher amount.
