Nonkeratinized stratified squamous epithelium can be found lining what area of the respiratory tract? alveoli nasal cavity bronc

mylen [45]

The answer is oropharynx. The reason for this type of epithelium in this region of the respiratory tract is due to its proximity to the esophagus. This means that this region of the respiratory tract is subject to abrasion by food passing down the esophagus. This epithelium is continuous with that of the esophagus.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding

slava [35]

Answer:

In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy . In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios

Dmitry [639]

Answer:

Please find the expected genotypes and phenotypes of the progenies of each cross below.

Explanation:

In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).

Considering the following crosses (find the punnet square attached);

a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)

b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)

c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L

Blood type MN (2) : Blood type N (1)

d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)

e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)

An unlabeled hierarchical diagram of various astronomical bodies is shown. The labels A, B, C and D can be used to represent the

Sliva [168]

Answer:

Part 1:

The four astronomical bodies one could choose to represent the 4 labels in the diagram are

A - universe

B - galaxy

C - solar system

D - Mars

The universe contains galaxies and galaxies holds solar systems which have planets like Mars

Part 2: D or a planet like Mars is unlike all their other astronomical bodies it does not have other astronomical bodies within it thus, its different from rest.
