Explanation:
Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families.
Answer:
(a) (Glu)zo or(Phe-Met)3 at pH 7.0
O (Glu)zo ✔
O (Phe-Met)s ❌
(b) (Gly) zo or (Lys-Ala)3 at pH 7.0:
O (Gly12) ❌
O (Lys-Ala)✔
(c) (Ala-Asp-Gly)s or (Asn-Ser-His)s at pH 3.0:
O (Asn-Ser-His)s ✔
O (Ala-Asp-Gly)s ❌
(d) (Ala-Ser-Gly)s or (Asn-Ser-His)s at pH 6.0:
O(Ala-Ser-Gly)s ❌
O (Asn-Ser-Hish)s ✔
Explanation:
Polypeptides that has polar or charged side chains are more soluble than polypeptides with nonpolar side chains.
(a) At ph 7.0
(Glu)20 is negatively charged at pH 7 and more soluble
(Phe-Met)3 is observed to be less polar and less soluble
(b)At ph 7.0
(Lys-Ala)3 is positively charged (polar) and more soluble
(Gly)20 is uncharged as only the amino- and carboxyl-terminal groups are charged as its less polar and less soluble too.
(c) At pH 6.0
(Asn-Ser-His)5 has polar Asn side chains and partially protonated His side chains and it's more soluble unlike the (Ala-Asp-Gly)s at that pH.
(d) At pH 3.0
(Asn-Ser-His)s as partially protonated carboxylate groups of Asp residues and it is also neutral but the imidazole groups of His residues are fully protonated and positively charged. Hence it's more soluble than the (Ala-Ser-Gly)s at that particular pH.
Answer
The best ways to create subject lines for email are;
• Keeping it short and to the point
• Maintaining a familiar sender name
• Avoiding the “no-reply” sender name
<u>The best reaction would be to send a follow-up piece of content that builds off the subject</u>
Explanation

• it should show urgency such as use of a phrase like ,”Act now!”
• Create curiosity in the subject line
• The subject line such show relevance and time consciousness
Option A,B,C,E
Chromosomes are rod shaped structures that contain DNA, are located in the nucleus, occur in numbers that are the same for all members of a certain species, are organized into karyotypes for scientists to analyze
<h3><u>
Explanation:</u></h3>
A chromosome is the threadlike arrangement of DNA and protein-containing genetic erudition. Chromosomes are packaged and saved inside the nucleus. Various species have distinct amounts of chromosomes. An organism's complete assortment of chromosomes can be observed by practicing pictures of cells dividing. These pictures are then designed to produce a karyotype.
All the various chromosomes of an organism get up that organism's genome.DNA is the construction block of the genetic material observed in all living things. A very long chain of DNA can create a chromosome. In these chromosomes are areas designated as genes that code for particular proteins.
