There are no statements given however a centriole is made up of microtubules triplets in a 9+0 pattern (I am unsure of what level of depth is required)
They are known as Gametes
Answer:
The correct answer is - the placenta, the site of exchange of materials between the mother and the fetus.
Explanation:
In the given diagram there is a representation of a human embryo developing in the uterus. Different parts are numbered and the number three represents the site of exchange of materials between the mother and the fetus and this organ is called the placenta. It is the organ that develops between fetus and uterus during pregnancy that allows substances such as nutrients, to diffuse from the mother's blood to the fetus and connected by the umbilical cord.
Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.
