what causes Earth's crust to crumble and fold
The Earth's crust crumbles and folds due to movements and interactions of tectonic plates that exert forces called stress, causing the physical deformation known as strain.
The Earth's crust crumbles and folds mainly due to the movement and interactions of tectonic plates. This process involves significant forces that cause the crust to bend, deform, and sometimes break, leading to the formation of folds and faults. These forces are known as stress, and the resultant physical changes in the crust are referred to as strain.
There are three basic kinds of stress:
Compression: Occurs when rock masses are pushed together, often creating folds in the rock. This typically happens when tectonic plates collide.Tension: Pulls the crust apart, leading to thinning and lengthening of the crust, such as the formation of rift valleys.Shearing: Takes place when plates slide past each other, cutting the crust into parallel blocks and displacing them horizontally.Deep within the Earth, as plates collide, rocks crumple into folds much like when you push on opposite edges of a piece of cloth. These processes not only shape Earth's surface but also result in geological activities like earthquakes and volcanic eruptions.

what evolutionary feature would distinguish phytoplankton from zooplankton?
The evolutionary feature that would distinguish phytoplankton from zooplankton is: nutrition and cellular structure.
Evolutionary Feature:
Phytoplankton and zooplankton are two distinct groups of plankton that play crucial roles in aquatic ecosystems, and they can be differentiated primarily by their evolutionary features related to nutrition and cellular structure.
Key Evolutionary Features
1) Nutritional Mode
Phytoplankton are autotrophic organisms, meaning they can produce their own food through photosynthesis or chemosynthesis. This ability allows them to convert sunlight or chemical energy into organic matter, making them primary producers in the aquatic food web. They are typically plant-like and include groups such as diatoms, dinoflagellates, and cyanobacteria.
Zooplankton, on the other hand, are heterotrophic, which means they cannot produce their own food and must consume other organisms, primarily phytoplankton. They are considered consumers in the food chain and include a variety of organisms such as crustaceans (like copepods and krill), protozoans, and larval stages of larger animals.
2) Cellular Structure
Phytoplankton possess chlorophyll and other pigments that enable them to capture light energy for photosynthesis. Their cellular structure is similar to that of plants, containing chloroplasts and a rigid cell wall, which can be composed of silica (as in diatoms) or cellulose (as in green algae).
In contrast, zooplankton lack chlorophyll and do not have the cellular structures necessary for photosynthesis. Their cells are typically more complex in terms of mobility and sensory structures, allowing them to navigate through water and respond to environmental stimuli.
Plant cells produce oxygen gas ____. by splitting carbon dioxide. by splitting ribulose bisphosphate. by breaking down glucose by splitting molecules of water.
Plant cells produce oxygen gas by splitting molecules of water.
• A kind of chemical reaction in which molecules are dissociated into smaller components by the activity of light is termed photolysis.
• For example, in the process of photosynthesis, the photolysis of water molecule takes place under the activity of light.
• During the process of photolysis, the absorption of photons takes place, which makes hydrogen to combine with an acceptor, and subsequently discharging the molecule of oxygen.
• The molecule of water acts as a substrate for photolysis in the process of photosynthesis, resulting in the formation of diatomic molecule of oxygen.
Thus, plant cells produce oxygen gas by splitting the molecules of water.

States that all living things are composed of cells, cells are the basic unit of life, and cells come from pre-existing cells
it is about the unified cell theory.
The statement you provided describes the fundamental principles of cell theory:
All living things are composed of cells: Cell theory asserts that all living organisms, whether they are single-celled or multicellular, are made up of one or more cells. Cells are the structural and functional building blocks of life.
Cells are the basic unit of life: Cell theory recognizes that cells are the smallest units of life and the fundamental functional and structural entities of living organisms. All life processes and functions occur within cells.
Cells come from pre-existing cells: This principle highlights that cells arise through the division of pre-existing cells. In other words, new cells are produced from the division of parent cells. This concept contrasts with the earlier idea of spontaneous generation, which posited that life could arise spontaneously from non-living matter.
Cell theory is a foundational concept in biology, and it was developed through the work of scientists like Matthias Schleiden, Theodor Schwann, and Rudolf Virchow in the 19th century. It provides a unifying framework for understanding the structure, function, and origin of all living organisms.

Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals. However, bed bugs have become resistant to even this chemical pesticide. What happened that allowed the bug population to increase? A) the chemicals used currently are weaker B) the chemicals no longer can penetrate bed bugs brains C) the bed bugs of today are exactly the same as the bed bugs of fifty years ago D) the bed bugs that survived the DDT years ago, reproduced new generations of chemical resistant offspring
Answer:
D) os percevejos que sobreviveram ao DDT anos atrás, reproduziu novas gerações de filhotes resistentes a produtos químicos
Explanation:
It is very common for chemical insecticides to cause insect-resistant insects such as bed bugs shown in the above question. This was because when DDT was used to exterminate the bed bug population, some of these insects had chemical resistance to this product, which means that the product had no effect on their organisms.
These bed bugs survived and reproduced, creating new bed bugs that inherited their genetic property capable of producing DDT resistance. These bed bugs also reproduced thus generating a population of resistant bed bugs. The result is that the product has become inefficient in this new generation of bed bugs.
