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.

A cell has a 2\%2%2, percent salt concentration. It is placed into a solution containing a 2\%2%2, percent salt concentration. What will happen to the cell?
Answer:
Neither the solute nor the solvent (water) will move in any direction
Explanation:
Concentration of salt with in the cell = 2%
Concentration of salt of the solution in which the cell is placed is 2%
Since there is no change of concentration of salt with in cell and outside the cell. Hence, there will be no net movement of solute or solvent.
Environmental impact has also been seen through human activity with agriculture. This is due to the high amounts of monoculture farming. Although having large agricultural fields of one crop can be efficient, it results in attracting a higher number of pests, which, in turn, results in a high use of pesticides. Identify a solution that would possibly remedy this issue and explain why that action would be beneficial.
Explanation:
Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.

Question 7
Tommy is investigating a strain of bacteria. He observes that the bacteria is only found in environments with a pH range from 6 to 8. His lab partner prepares a growth medium for this bacteria with a
Which explanation best predicts what will happen to the bacteria grown in this growth medium?
A
The bacteria will quickly die because the growth medium is too acidic for survival.
B
The bacteria will grow quickly and then begin to die because they will run out of food
с
The bacteria will grow slowly because the growth medium will provide fewer resources.
D
The bacteria will grow quickly because they can change the pH level of the growth medium
Answer: A, The bacteria will quickly die because the growth medium is too acidic for survival.
Explanation: it was only found in 6 to 8 pH range so it will not survive in pH of 5

the answer is d
Explanation:
compare the mechanism of gaseous exchange between an insect and a mammal
Explanation:
Insects have water at the ends of their tracheoles for oxgen to dissolve in to diffuse. ... The circulatory system makes the gas exchange system in fish and mammals more efficient than the gas exchange system in insects. Mammals and insects both get their oxygen from air, while fish get oxygen from water.

which statement is true about natural selection?
Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.
Give two land features that can form because of deflation.
Explanation:
Deflation can form certain land features. It can pro- duce desert pavement, which is a surface made of peb- bles and small, broken rocks. In some places, the wind can scoop out small, bowl-shaped areas in sediment on the ground. These areas are called deflation hollows.

What sort of fossils would be expected to be found in Antarctica from about the time of Pangaea (250 MYA)?
Answer:
Lystrosaurus as known as or translates to 'shovel reptile'.
Lystrosaurus is the only fossils of this creature have only been found in anatartica, India and south Africa.
Explanation:
Antarctica was once part of the supercontinent of Pangaea, which existed between 300 million and 200 million years ago.
What is the evidence of glaciation?During this time, Antarctica was located near the South Pole and covered in forests and swamps. Fossils of ancient plants and animals that lived during this time period would be expected to be found in Antarctica.
In particular, fossils of the Glossopteris plant, which was a dominant flora during the Permian period (299 million to 251 million years ago), are commonly found in Antarctica. Other fossils that have been found in Antarctica from this time period include those of primitive reptiles, amphibians, and some species of marine life.
In addition to fossils, evidence of glaciation is also found in Antarctica from the Permian period. This includes glacial deposits and striations on rocks, indicating that the climate in Antarctica was once much different than it is today. These fossils and geological features provide important insights into the evolution of life and climate on Earth.
