Answer:
plants have plant cell animal have animal cell
plant are autotroph animal are not
plant are fix animal can move
chlorophyll is in plant but not animal
Answer:
Option A. are mostly non-metals.
Explanation:
Oxidising agents are mostly non-metals because non metals gains electron from the metal during chemical bond and we know that oxidising agent is electron accepter not donar. For example, Sodium is a metal react with chlorine which is a non-metal so the sodium losses electron and this electron is gain by chlorine atom forming sodium chloride. In this example chlorine is a non-metal which gains electron.
Explanation:
A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.
But let us use the earth's geothermal gradient to solve this problem.
The geothermal gradient is the rate at which temperature is increasing with depth.
The geothermal gradient 25°C/km
At 5500°C,
5500°C x
= 220km
But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.

Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.
Each moon or planet matched to the most accurate characteristic;
1. It contains large amounts of frozen water - C. Europa
2. High levels of carbon dioxide increase the temperature of its atmosphere - B. Venus
3. It does not have enough gravity to have an atmosphere - A. Earth's moon
4. Astronomers believe there is a good chance it contains liquid water - D. Mars
Europa is the smallest of the four Galilean moons of Jupiter. Others are Io, Ganymede, and Callisto. An outer layer of water, about 100 km (62 mi) thick, covered the surface of Europa. A part of the outer layer (crust) is said to be frozen, while the other part is a liquid ocean below the ice.
Venus is the second planet from the Sun and the hottest planet in the solar system. The atmosphere of Venus is dense, and it is composed mainly of carbon dioxide (roughly 96.5 percent), which traps heat and causes a greenhouse effect.
