The answer is A. The eggs do not have a shell to prevent water loss.

Toad's eggs do not have a shell, like reptile eggs or bird eggs. Shell is important because it protects eggs from drying out if they are laid in the land. Toads lay eggs in a jelly-like glycoprotein. Thanks to glycoprotein around toad's eggs, contact with water is maintained all the time so that eggs don't die.

Which structure makes proteins using coded instructions that come from the nucleus?

Gelneren [198K]

Fundamentally, the cell would cease to function and possibly die. Proteins are used for cellular repairing and chemical processes. Ribosomes are one of the most important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures enzymes such as proteins which will be utilized by many organelles in the cell. Microtubules are one, responsible for the framework and acts as a skeleton of the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of the cell. For a prokaryote or a eukaryote cell to survive, they need protein.

Systematic separation of the circulation of the blood. The right side of the heart receives oxygen-poor blood from your body and pumps it to the lungs. The lungs oxygenate the blood which returns to the heart and is pumped to the rest of the body by the left side of the heart. After which the blood returns to the right side, completing the cycle of circulation.

If Avery had observed transformation using only the extracts containing degraded DNA, degraded RNA, and degraded protein, but NO

Leokris [45]

Answer:

Polysaccharides are the genetic material.

Explanation:

Avery did not observe transformation using the extracts containing degraded DNA. On the other hand, extracts with degraded RNA, proteins, and polysaccharides exhibited transformation. Therefore, he concluded that DNA is the genetic material responsible for transformation. If he would have observed the process of transformation using extracts containing degraded DNA but not with degraded polysaccharides, he might have concluded that "polysaccharides were the genetic material responsible for the process of transformation."
