According to the history and physical examination of the patient, the patient may have a upper gastrointestinal bleed most probably from a bleeding peptic ulcer. A bleeding peptic ulcer can cause abdominal pain and vomiting described as coffee ground vomit because of the reaction of the blood with the stomach acids. The patient's vital signs signify that the patient is in the state of hypovolemic shock. The emergency medicine consultant should use an oxygen mask with caution because additional vomiting episodes may recur and if the patient is wearing an oxygen mask, the vomit cannot be cleared thoroughly and may even cause aspiration.
Back in Darwin’s time, people thought that animals sources were a nonhuman ancestors.
Explanation:
Of the energy that reaches the Earth from the Sun, a small amount is absorbed by the atmosphere, a larger amount (about 30%) is reflected back to space by clouds and the Earth's surface, and most of it is absorbed at the planet surface and then released as heat.
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection.
Molecules of all substances, even solids, have random motion and therefore an associated kinetic energy and temperature. ... Completely empty space would have no temperature since there are no molecules there.

Explanation:
The phase of Prophase I of meiosis is very long and divided into 5 subphases: Leptotene, Zygote, Pachytene, Diplotene, and Diakinesis. During a phase of the Diplotene, the degree of condensation is high, which allows individualizing the sister- chromatids that remain attached by the cohesins. The synaptonemal complex disintegrates, and from the centromeres begins a repulsion between homologous chromosomes, which remain associated only with the places where they occur as permutations.
These sites are called chiasmas (Greek, crossed) because they show the crossover of homologous chromatids. Chiasmas represent the cytological finding of the occurrence of permutation. The presence of at least one bivalent chiasm is essential to ensure the correct segregation of the homologous chromosomes in anaphase I.
I believe the answer to this is Pictograph.
