Answer:
D
Explanation:
Amphibians have eggs that need to be constantly submerged in water. The amniotic egg is like a chicken egg. It doesn't need to be submerged in water, but it does need to be kept warm.
The lynx population decline follows the snowshoe hare population crash after a lag of one to two years.
Sorry if I am wrong, let me know if there were any choices.
Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
The answer is D) Structural
That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is <span>C6H12O6, that leaves us with choice D.

I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured.
Answer:
A scientific investigation is a plan for asking questions and testing possible answers. A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.
