From the parent with genotype Aa, what is the best prediction of the gametes? A.100% of the gametes will carry a dominant allele
, b. Every gamete will have both the A and the a allele, c.50% of the gametes will carry a dominant allele, 50% of the gametes will carry a dominant allele,d.75% of the gametes carry neither the A or the a allele
A. objects made of crystals minerals water and air
Process of elimination- there isn’t organic matter in rocks so D is out they are made of minerals so B is out some types of rock (pumice) have air bubbles in them so A is more likely than C
When energy flows in a food chain, it is observed that the amount of energy flow decreases with successive trophic levels.
It is generally observed that approximately 90% of the energy available at a trophic level is used up and only remaining 10 % is transferred to the next .
This is termed as<em> </em><em>ten percent law.</em>
Thus, we can say that 90% of energy is lost when the energy is transferred from one trophic level to another.
