Answer:

A

Explanation:

a - What happens when organisms don't decompose? If there were no decomposers, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

b - What happens when a catastrophic mass extinction occurs? A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a 'short' amount of geological time - less than 2.8 million years

c - What does the shifting of tectonic plates cause? At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.

d - Volcanic ash doesn't actually do that.

Now, how do fossil fuels form? After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Fossil fuels are formed when the organic matter that has been buried deep within the earth is subject to heat and pressure over millions of years. In both cases, heat and pressure are critical to the formation of fossil fuels.

All viruses differ from bacteria in the sense that viruses cannot reproduce outside of a living host but bacteria can.

Virus is a submicroscopic, non-cellular structure consisting of a genetic material (DNA or RNA) surrounded by a protein coat called capsid.

A bacterium cell, on the other hand, is a single celled organism with cell walls but no nucleus or organelles.

A virus requires a living host cell to replicate while a bacterium can replicate itself irrespective of a living host.

Answer:

The endosperm is formed

Explanation:

double fertilization, in flowering plantreproduction, the fusion of the egg and sperm and the simultaneous fusion of a second sperm and two polar nuclei that ultimately results in the formation of the endosperm (the food-storage tissue) of the seed. This is called double fertilization because the true fertilization (fusion of a sperm with an egg) is accompanied by another fusion process (that of a sperm with the polar nuclei) that resembles fertilization. Double fertilization of this type is unique to flowering plants (angiosperms) and is responsible for the formation of both the embryo and its potential food source in the seed.

The cells were first discovered when a scientist named Robert Hooke observed cell walls in cork under a microscope.

Robert Hooke's observation made it possible to visualize the dead cell walls of cork, even without knowing what the image represented, exactly, and without relating living beings to a cellular composition.

In the beginning, the cell theory was elaborated by the scientist Robert Hooke, in the year 1665. Based on this research, the cell is a morphophysiological unit of all living beings, that is, it corresponds to the smallest unit of life.

Explanation:

Flash memory provides stability to the

BIOS framework and makes update

installation much easier than with CMOS.

Because these two transistors are complementary to one another, a circuit created by combining them is referred to as a complementary MOS circuit, or CMOS circuit for short. Thus, option D is correct.

The majority of modern integrated circuits, commonly referred to as chips or microchips, employ a complementary metal-oxide semiconductor (CMOS) as their semiconductor technology.

Metal-oxide semiconductor field-effect transistor technology is the foundation for CMOS transistors.

Several analog circuits, including image sensors (CMOS sensors), data converters, and highly integrated transceivers for various forms of communication, also use CMOS technology.

Therefore, BIOS framework relocated to flash memory from a complementary metal-oxide-semiconductor (CMOS) in later development.
