Answer:
The stem, which has two parts. The inner tissue is known as the xylem. It moves water and minerals from the roots to the leaves. The outer tissue is the phloem , which transports food from the leaves to the rest of the plant through a process known as translocation

Selective breeding occurs either by inbreeding or cross breeding. Selective breeding involves choosing and breeding the species with most desirable qualities. The biggest and most muscular male horses were crossbred with the biggest and most muscular females to produce the strongest offspring.
True thinking and questioning is the start of the scientific inquiry process.
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.
