Answer:
Jack i right
Explanation:
it seems awfully strange if only one type of material makes up the whole soil.. obviously the soil will consist of more than one. most soil is made up of minerals, rocks and organic matter , remember that they have several particles within them with different measurements.
Answer:
Water droplets form on the grass
Explanation:
The cool air is less dense than the water that has condensed so dew forms on the grass.
Answer:
The correct answer will be-
1. Mobile elemests- LINEs and SINEs
2. Exons
3. Non-coding RNA genes
4. Introns
5. Repetitive DNA sequence
Explanation:
The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.
The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.
The non-coding sequence includes the Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.
Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.

Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
