It is about 4.22 light-years<span> from Earth and is the closest star other than the sun. Alpha Centauri A and B orbit a common center of gravity every 80 years. The average distance between them is </span>about 11 astronomical units<span> (AU) — about the same distance as the sun is to Uranus.</span>
Answer:
the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Explanation:
I think it can be incorrect also so refer to Science teacher also. also.
Chemosynthesis is the biological conversion of one or more carbon- containing molecules.
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
Answer:
represses gene transcription and promotes mRNA translation.
Explanation:
Homeotic gene refers to any group of genes that controls the pattern of formation of body structure during early embryonic development of organisms. These genes encode proteins which is called transcription factors that direct cells to form various parts of the body. Homeotic genes is the master control genes that regulate other groups of genes that are responsible for the development of body parts that will develop in different locations.
