Closely related organisms pass through similar embryonic stages. The earlier the divergence of embryos occurs between two species, the more distant their most recent common ancestor, as with the vertebrate/insect gastrea example above
Answer:
This question is incomplete as it lacks a word bank, the word bank are:
Ions
Electrons
Isotopes
Molecules
Covalent
Negative
Ionic
Molecular
Hydrogen
Point
Element
Ionic compound
The answer is:
1. Ions
2. Ionic
3. Covalent
4. Molecule
Explanation:
An ION is a charged atom i.e. an atom with positive (+) or negative (-) charge, which results when an atom loses or gains electrons respectively. The ions of different elements are held together by bonds called IONIC BONDS, which are bonds that form as a result of the difference in electric charges or electrostatic forces between the atoms involved. For example, an ionic bond forms between NaCl because there is an electrostatic force between the positive Na+ ions and negative Cl- ions.
However, on the contrary, when electrons are shared between atoms, a COVALENT BOND is formed. The atoms share their valence electrons to form a MOLECULE, which comprises of two atoms.
Answer:
Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines.
Explanation:
Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules.
Answer: Genes
Explanation: Genes that are responsible for muscle strength contributes to athletic performance but if you're being trained for sports and your gene responds to the training, then you may become a good athlete. It is also influenced by environmental factors.
Mother and father traits contribute athletic ability to their child.
