Answer:

5.5 seconds

Explanation: You can either use a proportion or simple division for this, depending on how it is requested.

<u>Proportion</u>

14 mm/1 sec = 77 mm/x sec [cross multiply]

14x = 77 [divide 77 by 14 to isolate the x]

x = 5.5 seconds

<u>Simple Division</u>

The disease cystic fibrosis (CF) is caused by a mutation to the CFTR gene which affects the respiratory, endocrine, reproductive
Lady bird [3.3K]

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.

Explanation:

Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.

It is best to say that the protection to properties offered by sea walls along coasts _______.
Mashcka [7]

Answer: a.  decreases the present and future risk to human properties

Explanation:

Properties along the coasts can be in danger when high tides come in. This can however be mitigated by walls protecting those properties as it would take a significantly high tide (flood proportion) to scale those walls and come in and damage the property.

These walls therefore not only decrease the present risk to human properties but if maintained, decrease the future risks as well.

creativ13 [48]
The correct answer is letter C, in most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs.
