What evidence did they give for this transition?Explain your answer.

Virtual museum visit – evolution in the dinosaur and bird clades

Go to https://www.biointeractive.org/classroom-resources/interactive-assessment-origin-birds and launch the interactive video. As you are watching the video you will need to complete the assessment questions along the way to proceed. Watch the entire video. Think about the evolutionary steps needed to separate a flying, endothermic avian from scaled, running reptiles. What evidence did they give for this transition?

Using the evidence you gathered from the virtual path, you will discuss evolution in the dinosaur and bird clades. You will need to gather 2 outside sources to use, in addition to the AMNH information or HHMI information. These sources must be peer reviewed, scientific journal articles. The sources cannot be older than 20 years , cannot be books or review articles, and cannot be websites. You will paraphrase information from these sources into your own words to construct a valid argument for your thoughts.

 

What will be the probable genotypic and phenotypic ratios of their offspring?

GENETICS PROBLEM SOLVING
Monohybrid Crosses

Free ear lobes in humans is dominant (F) to attached earlobes (f). Show the cross between two individuals that are heterozygous for free earlobes. Solve by filling out a Punnett square. What will be the probable genotypic and phenotypic ratios of their offspring?

Tongue rolling in humans is a dominant trait to non-rolling . If two parents are unable to roll their tongue, what will be the genotypic and phenotypic ratios of their offspring? Solve by filling out a punnett square

An animal breeder wants to know if a black guinea pig is homozygous or heterozygous for coat color. He test crosses the black guinea pig with a homozygous recessive white guinea pig. If one of the offspring is white, what is the genotype of the black parent guinea pig?

Pedigree Study
The ability to taste a chemical called PTC  is controlled by a dominant gene (T). Use (t) for non-tasters. Shaded individuals cannot taste PTC. Record the genotype for all designated individuals using the table below the pedigree. For unknown dominant phenotype individuals use (T?).

What is the role of ACh at the neuromuscular junction? Describe the resulting electrical changes in the muscle.

1. Elizabeth suffers from severe muscle weakness. She finds it difficult to move her facial muscles, and the simplest facial movements involve a lot of effort. She was told she suffers from a disease characterized by a reduced effectiveness of released ACh and frequent failure of neuromuscular transmission.
a) What is the role of ACh at the neuromuscular junction? Describe the resulting electrical changes in the muscle.
b) Elizabeth’s doctors believe his disease is an autoimmune disorder because it targets acetylcholine receptors at the neuromuscular junction? What happens to the ACh if this is the case?
c) Propose a treatment option for Elizabeth and describe how and why you think this treatment would work- do not provide a description of existing drugs. Explain what a drug should do to help this condition.
d) What targets other than the receptor might be affected by an autoimmune disorder that might have similar effects?

What current therapies target cancer cell metabolism and are they selective in not harming normal cells?

Answer the question. There is a 300-word cap on this part; references do not count toward this word limit. Posts that demonstrate quality, clarity, depth, ; focus will be more positively evaluated than posts that are shy on these key elements. also add pic after your explanation and make sure to add the pic source in APA format in reference section.

Studying how cancer cells might arise and how they survive are important to developing effective treatments against them.

Molecular evolution and phylogeny
At the molecular level, evolution is a process of mutation with selection. Molecular evolution is the study of changes in genes and proteins throughout different branches of the tree of life.
Phylogeny is the field of study of the inference of evolutionary relationships. Phylogeny is
centered on the use of tree-like diagrams to represent evolutionary pedigrees. Traditionally, phylogeny relied on the comparison of morphological features between organisms. Today, molecular sequence data are also used for phylogenetic analyses. Molecular phylogeny is based on sequences and the comparison of sequences. Multiple sequence alignment is crucial to molecular phylogeny.
Goals of molecular phylogeny:
A TRUE TREE depicts the actual historical events that occurred in evolution. However, it is essentially impossible to generate a true tree. Instead, we generate inferred trees, which depict a hypothesized version of historical events.
Some major goals of molecular phylogeny are to deduce correct trees for all species and to
estimate times of species divergence. Here are some questions that molecular phylogeny may help answer:
(i) How many genes are related to my favorite gene?
(ii) How related are whale, dolphins and porpoises to cows?
(iii) When and where did HIV and other viruses originate?
(iv) What is the history of life on earth?
(v) Was the extinct quagga more like a zebra or a horse?
