Answer:
C
Explanation:
Ionic bonds are formed between elements where one is ‘happy’ to loose electrons (mostly metals) to attain stable electron configuration while the other is ‘happy’ to accept electrons (mostly non-metals) to achieve a stable electron configuration. The atoms, therefore, becomes charged after the loss/gain of electrons and come together by electrostatic forces.
An example of a compound formed by ionic bonds is NaCl. Na loses its valence electron to Cl to become [Na+][Cl-] while they both attain stable electron configuration of 2.8 & 2.8.8 respectively.
Answer:
Bb or BB
Explanation:
since brown hair was the dominant allele it only has to have one big B to serve as a heterozygous dominant trait. Therefore, the person has brown hair. If you were looking for blond hair it would have to be bb because it is a recessive trait and you need two recessive traits to make up a certain genetic trait.
Heterotrophs are organisms that depend on other organisms for food. For example, a bird would be a heterotroph. A bird eats other organisms like worms and beetles. A plant would be an example of an autotroph, which is an organism that makes it’s own food.
The correct answer would be D. gets food from outside itself.
