The geological history of Earth follows the major events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System.
Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as a result of the impact of a planetoid with the Earth. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
As the surface continually reshaped itself over hundreds of millions of years, continents formed and broke apart. They migrated across the surface, occasionally combining to form a supercontinent. Roughly 750 million years ago, the earliest-known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia, 600 to 540 million years ago, then finally Pangaea, which broke apart 200 million years ago.
The present pattern of ice ages began about 40 million years ago, then intensified at the end of the Pliocene. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years. The last glacial period of the current ice age ended about 10,000 years ago
I searched for the image and it points out to the liver. According to the choices, the answer is "converting toxins to less toxic forms" as the liver functions to detoxify substances through its cells (particularly in the smooth endoplasmic reticulum) via the cytochrome p450 system. Detoxification involves 2 phases, first is Phase I wherein the p450 system makes the toxic substance more hydrophilic (it means it is easily soluble to water) and can be readily excreted by the kidneys. If Phase I is insufficient, then the toxin enters Phase II which is conjugation with other molecules to make the toxin even more hydrophilic. The liver does not produce urine and excreting salt and urea as this is the function of the kidneys. The liver's main function is not digesting foods and liquids as that is the main function of the gastrointestinal tract, but the liver aids in the absorption of fats by the secretion of bile, thereby emulsifying the fats rendering it ready for absorption.
Answer: Options are not given.
Here are the options.
A. Autotrophs
B. Saprophytic
C. Parasitic.
D. Both a and b.
E. All of the above.
The correct option is all of the above.
Explanation:
Angiosperms are flowers and seed producing plants and their seeds are enclosed in ovary.The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and then develops
into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.
Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.
Examples include maize, rice..
Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.
Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.
