Answer:
Drogas.
Explanation:
Las drogas son sustancias que tienen un efecto modificatorio sobre el estado normal de la psique. Por tanto, estas sustancias influyen en el comportamiento o la experiencia del usuario, pudiendo tener un efecto alucinógeno, pero también sedantes o una mixtura entre ambos.
El término se usa generalmente para indicar sustancias que tienen un efecto muy fuerte (por ejemplo, heroína, cannabis, mescalina, alcohol). Aunque los estimulantes cotidianos como el café y el chocolate también pueden tener un efecto en la psique, generalmente no se clasifican como sustancias psicoactivas debido a su efecto relativamente leve.
Los medicamentos que tienen un efecto sobre la psique se denominan psicofármacos. No obstante, los medicamentos que no se clasifican principalmente como psicofármacos, como los antihistamínicos, los agentes anti-mareo y los betabloqueantes, pueden también tener un efecto psicotrópico.

In what period did fish, mammals, reptiles, amphibians, and plants appear on earth?

In Cretaceous Period,fish mammals,reptiles,amphibians,and plants appeared on the earth.
The Devonian Period lasted 417 million to 354 million years. Ammonites, starfish, corals, crinoid stems, armored fish, sharks, early bony fish, and early amphibians were among the living things during the Devonian Period.
What is Devonian Period?The Devonian, a Paleozoic era, is also known as the Age of Fishes because it produced a diverse range of fish.
The most fearsome were the armored placoderms, a group that first appeared during the Silurian period and had powerful jaws lined with bladelike plates that acted as teeth.
Throughout the Devonian period, the Earth was hotter and drier than it is nowadays.
Warm and equatorial climates were widespread, as evidenced by the abundance of evaporite basins in the Northern Hemisphere, coal deposits in Arctic Canada and Spitsbergen, as well as pervasive desert circumstances and carbonate reefs.
Dunkleosteus terrelli was the largest species and most likely the largest fish in Devonian times. It could eat almost anything because it was one of the largest and most powerful fish ever.
Thus, the fish, mammals, reptiles, amphibians, and plants appeared on earth in Devonian Period.

How are the functions of the small intestine and the large intestine different? A: The small intestine absorbs nutrients and wastes out of the digested food, while the large intestine produces a digestive juice to break down the food. B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste. C: The small intestine provides oxygen to the digested food before it goes to the rest of the body, while the large intestine absorbs nutrients and wastes from the food mixture. D: The small intestine pumps food and nutrients throughout the body, while the large intestine turns the digested food into a thin liquid mixture. PLS HELP
Answer:
B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste.
Explanation:
Small intestine and large intestine are the important organs of digestive system in the human body. The small intestine functions by absorbing the nutrients of the simpler form of food. After absorbing the nutrients, the residue left is passed to the large intestine. The large intestine absorbs the water and further helps in eliminating the feces. It do not produces any enzyme to break the food unlike the small intestine. The process of digestion is completed by the small intestine.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.
Describe the different factors that influence cell division. Include information related to the cell cycle and internal and external factors.
