19. If a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified?
Illusion [34]

<u>ANSWER:</u>

The correct option is B- Qualitative.

<u>EXPLANATION:</u>

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.

Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.

Ksenya-84 [330]

Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.

Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.

Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.

The correct option is B.

Give an example in the human body of a molecule cotaining ionic bonds
Lemur [1.5K]
<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.
</span><span>
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>
