<span>An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.

Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.</span>
DNA<span> - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.</span>
Answer:
Both are correct
Explanation:
The modern system classifies organisms into eight levels: domain, kingdom, phylum, class, order, family, genus, and species. The scientific name given to an organism is based on binomial nomenclature.
The "traditional" system relies on Linnean classification (what looks similar between the the two species.
Answer: 41.5 OMGs is the predicted mean cuteness in the next generation.
Explanation:
Cuteness is a way to measure relative ability of individuals with a certain genotype to reproduce successfully.
Mean cuteness is given as the summation of individual cuteness. Mean cuteness also changes in the next generation.
The mean cuteness of the current herd was given as 39.7 OMGs and after 16 individuals were chosen, the mean was given as 41.5.
This implies that there was a change already as mean cuteness will either increase or decrease in the next generation after selection. Here, 39.7 increased to 41.5 .
The predicted mean cuteness is therefore 41.5 OMGs.
Well, a eukaryotic has a Membrane-Bound Nucleus.
Answer:
The answers to both parts (1 and 2) are given below.
Explanation:
1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.
2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.
