Natalka [10]

Answer:

There is no cure for cystic fibrosis, but treatment can ease symptoms and reduce complications.

Explanation:

1). For those with cystic fibrosis who have certain gene mutations, doctors may recommend a newer medication called ivacaftor. This medication may improve lung function and weight, increases the activity of Cystic fibrosis transmembrane conductance regulator (CFTR)protein and reduce the amount of salt in sweat. It has been approved by the Food and Drug Administration for people with cystic fibrosis who are age 6 and older. The dose depends on your weight and age.

2). For people with a certain gene mutation who are age 12 and older, another drug is available that combines ivacaftor with a medication called lumacaftor. This drug is called orkambi.

The use of Orkambi may improve lung function and reduce the risk of exacerbations.

I hope you're clear on this Daxxy

Name two types of evidence used to support the theory of evolution. explain how scientist use each type of evidence to provide s
joja [24]

Answer:

There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera

Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.  

For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.  

It shows divergent evolution and supports that these organisms have evolved from a common ancestor.

Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.

For example:

  • The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
  • Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.

A pink unicorn is crossed with a blue unicorn and all of the offspring are lilac, caused by the presence of both pink and blue h
siniylev [52]

Answer:

The correct answer is codominant.

Explanation:

A phenomenon in which two heterozygous alleles get expressed completely in the offspring produced is termed as codominance, and the trait produced is termed as a codominant trait. In codominance, both the alleles show their presence, that is, none of them is considered dominant, and like incomplete dominance, the alleles do not get mixed up.  

For example, in the given case, the crossing between a pink unicorn and a blue unicorn produces an offspring, which is demonstrating both pink and blue color fur. This shows that the phenomenon of codominance is taking place and the produced trait is an illustration of codominant trait, as the produced offspring is having both pink and blue color hair.
