Which of the following is/are characteristic of the earth but not the moon? A. Molten core B. Plate tectonics C. Asteroid impacts D. Volcanoes
<u>Answer:</u>
Plate tectonics is characteristic of the earth but not the moon
<u>Explanation:</u>
Tectonic plate movements in Earth are forced by convection in the mantle-the hard mantle transits at rates of a some centimeters a year. The Moon’s mantle, too cool to travel easily, has no convection and no moving tectonic plate motions. More uncommon movements inside the Moon indicate fewer quakes. The few moonquakes that do happen are made fundamentally by gravitational tugs by Earth and Sun ).
The quantity and intensity (magnitude) of moonquakes is much less than the quantity and consequence of earthquakes. The feasible reason of this discrepancy is the Moon's smaller size and cooler interior. Earth is hot and active, manifested most dramatically in plate tectonics. The secret of plate tectonics is that the Earth has gaps between the continents, and so they can move around like a sliding block puzzle.

Answer:
What is the main function of chloroplasts in a cell?
Chloroplast houses the chlorophyl that gives green pigment which is used by plant to trap sunlight and undergo photosynthesis
Explanation:
<span>Central dogma by Crick is explaining how a gene is translated. It involves transcription and translation. Transcription is copying the message of DNA to mRNA. This message is translated in the cytoplasm by ribosomes with the help of tRNA to syntheise proteins which are basis of every metabolic reactions. This is an inference based on observations. For him it was found reasonable to infer the message should be carried from DNA to cytoplasm.</span>
Answer:
Q = 813.12 j
Explanation:
Given data:
Mass of lead = 21 g
Initial temperature = 25°C
Final temperature = 327.5°C
Amount of heat absorbed by lead = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 327.5°C - 25°C
ΔT = 302.5°C
Specific heat capacity of lead = 0.128 j/g.°C
Q = m.c. ΔT
Q = 21 g. 0.128 j/g.°C.302.5°C
Q = 813.12 j
