Answer:

solar Nebula and planetesimals

Explanation:

About 4.6 billion years ago, a huge cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening into a disk called the solar nebula. Most of this interstellar material contracted in the center of the disk to form the sun, and some of the gas and dust remaining in this solar nebula condensed to form the planets and the rest of our solar system. In short, a solar nebula is a cloud of gas, dust, ice, debris.

The best theory for the formation of the Solar System and, by extension, other planetary systems, says that the remnants of the Sun's formation eventually condensed to form the planets, the protoplanetary disk - a fine interstellar dust that gradually coalesced and joining debris and ice in ever larger and more massive bodies called planetesimals. This growth produced asteroid-sized bodies that, by the same process of collision and agglutination, gave rise to the planets.

Answer:

Answered below

Explanation:

Head injuries may be penetrating head injury or closed head injury.

A major concern for health professionals regarding intracranial injuries resulting from closed head traumas, is the management of intracranial pressure. Elevated intracranial pressure have negative effects on the brain and immediate management of raised intracranial pressure is important to avoid cerebral edema, intracranial hematoma, brain herniation and even death.

The usual procedures in the management of head injury include elevating the head to about 30 degrees. This position promotes cerebral venous drainage and decreases intracranial venous pressure and intracranial pressure as well.

This is helpful because when the patient is left in the horizontal position, the intracranial pressure becomes significantly higher and the have fatal consequences.

Pigment molecules capturing photons in the chloroplast are organized in distinct structures called.
hjlf

Pigment molecules capturing photons in the chloroplast are organized in distinct structures called photosystems.

Photosynthetic pigments, which include chlorophyll a, chlorophyll b, and carotenoids, are light-harvesting molecules found in chloroplast thylakoid membranes. As previously stated, pigments and proteins are organized into complexes known as photosystems.

Photosystems are functional units for photosynthesis that are defined by specific pigment organization and association patterns. Their work is the absorption and transfer of light energy, which implies electron transfer. Photosystems are physically found in thylakoid membranes.

Chloroplasts are chlorophyll-containing organelles found in plant cells; they are essential for life on Earth because photosynthesis occurs in chloroplasts. Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, and other plastids. Light energy absorption and conversion into biological energy
