Body parts of unrelated organisms that serve the same function are examples of convergent evolution.
<span>Convergent evolution is the phenomenon when the different species independently create similar features. Those features can be structures that have similar form or function. This happens because organisms have been adapted to similar environments or ecological niches.</span>
D. Asteroids vary greatly in size and are mostly made up stone, iron and nickel
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.
Explanation:
Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
The enzyme pepsin functions with a very low pH of around 2. It is found in the stomach, with the acidity coming from the hydrochloric acid present there. it breaks proteins into amino acids.
