In hot springs the rising superheated water is cooled below the boiling point by groundwater before reaching the surface. In geysers the superheated water collects in underground pockets.
Answer: Option A
Explanation:
The effector response that increases the body is not associated with vasodilation of dermal blood vessels.
The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.
Unlike, them the vasoconstriction retains heat and increases the body temperature.
So, the correct answer is option A
Analyzing the proteins of the Racoons and lesser pandas, there will be huge similarities with minor modifications.
These species will be very closely related.
<h3><u>Explanation:</u></h3>
The evolutionary background of the species are mainly studied based on the similarities of the nucleotide sequences and proteins. While studying the Lesser pandas and Racoons, there was a huge similarities in then based on their structures, and on their protein composition. The nucleotide sequences also showed huge similarities which also points that they have developed from same ancestor. This is why they are very closely related with each other by means of evolution.
Plants use photosynthesis
Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.
