Scientists have debated the evolution of three life forms: reptiles, birds and dinosaurs. After many years of reviewing fossil r
ecords scientists proposed the evolutionary relationship seen above in the cladogram. Using radiometric dating scientists added a time frame for the evolution of the animals within the model. Based on this new information, what prediction can we make about the animals represented here? MYA refers to millions of years ago. A) Dinosaurs were the last to evolve among these groups of animals. B) Crocodiles are the most highly evolved of the animals represented here. C) Dinosaurs lived and became extinct before the arrival of lizards and snakes. D) Turtles were the first group of animals to branch off in this tree of animals.
D) Turtles were the first group of animals to branch off in this tree of animals.
Turtles were the first group of animals to branch off in this tree of animals. According to the tree, the animals share a common ancestor. The first branch shows that what we call a speciation event occurred, resulting in two lineages. The first group of animals to result were the turtles. All the other animals are on the other branch. This does not indicate that any group is more highly evolved than the other.
"The liver produces bile which emulsifies fats i.e. breaks them down into small droplets for a larger surface area. This will increase the rate at which the fat is digested by lipase. Bile also neutralizes the acid produced by the stomach to provide ideal alkaline conditions for enzymes in the small intestine."
D. TT x tt. When using a punnett square and substituting with the different genotypes, all of them will be Tt. And since T is the dominant trait, the offspring will be very tall.
In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.
