The given statement is true.


The act of terrorism carried out by the government of a state against the citizens of that state or against any foreign threat is called state terrorism. Any violent action that generates terror in people can be considered terrorism, but for the government it is just a violent act by the State.

Before, it was considered an act of the government against its people, but now it is considered an act of terror by a foreign power against the government. An example of such a government act is the attack on North Korea by agents of the Korean flight.

ENERGY PYRAMIDS Energy pyramids show the relative amount of
available energy for each trophic level.
Only about 10% of the available energy in the
a trophic level is transferred to organisms in
next trophic level. The other 90% is lost
through heat and other bodily processes.
1. List 2 bodily processes you think about
energy is lost.



Energy is lost at various levels in an organism's body. Two of the phenomena by which energy is lost are


When a body is in contact with another body, energy is lost in the form of heat. For example, if we sleep on the cold floor, our body's energy will be lost to the floor in the form of heat,


Energy is lost when cells in a body die, and energy is also needed for decomposition.

It describes three formations created by



If it has to do with land formations, then their suspension, creep and bouncing


"These three different types include suspension, creep and bounce. Suspension occurs when wind carries fine particles of dirt and dust into an area and can move these particles over long distances. Creep occurs when soil particles roll over an area and become particles of encounter that underwent saltation".


"Suspension, springing and surface creep are the three types of soil movement that occur during wind erosion. Although soil can be washed away at virtually any height, most (over 93%) of soil movement occurs within one meter or less."


Answer: It is suspension, flow and saltation.


Why is there so much less energy available to top predators than to top-tier consumers in a food web?


Answer and explanation:

Most of the food consumed by herbivores (primary consumers) passes through the digestive tract as undigested matter that is eliminated in the feces. Most of the absorbed food materials are used in respiration to release energy. Only a small proportion of consumed food is incorporated into the consumer's tissues, while the remainder is lost through excretion. Only food embedded in tissues can pass on to primary predators and secondary consumers.

How do populations change over time? (human)



Population change can be simply described as changes that occur in the number of people living in a specific area over a period of time. There are a number of factors that determine the change in the population:

  • birth rate
  • mortality rate
  • migration rate

If an area has resources for a better human life, like good jobs, without malnutrition, more people will migrate to those places. As a result, the population will increase in this area. If the population increase is not controlled, it can have devastating effects on the area.

To maintain equilibrium, the number of birth rates must equal the number of death rates.

If the population of an area increases more than its carrying capacity, people will either have to migrate or will die due to scarce resources.

Which technique improves the overall health and productivity of a forest by decreasing competition? (APEX) A. Desertification
B. Clear cut
C. Slash and burn
D. Slimming



The correct option is D. Roughing


In biological studies, thinning can be described as a process in which certain types of trees are removed from a forest to facilitate the growth and health of other trees.

For example, eucalyptus is adapted to consume a lot of water. In a forest, these types of trees cause water shortages for other trees. The other trees will be competing for water. Therefore, if some eucalyptus trees are removed, the growth of other trees can be facilitated.


The correct answer is d


  • Thinning: an important forest monitoring device. Thinning is the word that foresters refer to the removal of some trees from a stand to give others more opportunity (and support) to develop.
  • In conservation, thinning is the careful removal of trees, primarily to increase the rate of maturity or fitness of surviving trees.

The theory of plate tectonics was developed with input from scientists from a variety of disciplines. What contribution have geophysicists contributed to our understanding of seafloor ridges and plate tectonics? for. Deep-sea ridges show that life may have evolved along tectonic plate boundaries.

B. Debris from dead marine animals on the ocean floor shows that new tectonic plates are constantly being formed.

C. Earth's magnetic fields captured in rock around deep-water ridges show that fresh magma emerges between tectonic plates.

d. Mountain ranges on the ocean floor show that tectonic plates can rise and fall over several hundred million years.



C. Earth's magnetic fields captured in rock around deep-water ridges show that fresh magma emerges between tectonic plates.


  • From paleomagnetism studies and evidence of seafloor spreading, it can be easily identified that the ridges that were present in Earth's mid-oceanic ridges underwent a transformation of their properties as they aligned with the magnetic fields of the ridges. show an upwelling of fresh lava and rocky finds near the summits.




In a continent-continent convergence, - ocean basins are formed
folded mountains occur
both continental plates are subducted
volcanic mountains cannot form



At continent-continent convergence, folded mountains occur.


  • Continental crusts are buoyant and do not subduct.
  • If in this case two continental plates collide with each other, they break apart and lift the land to create mountains.
  • These mountains that are created are folded mountains. for example, the Himalayas, the Appalachian Mountains, etc.
  • Sometimes continental convergence causes massive earthquakes.
  • Since the continental crust is quite thick, it lies far below the mantle and therefore magma cannot rise to the surface. Therefore, volcanoes do not form.


convergence of continents, folded mountains occur

This shows the comparison between the size of an object's exterior and the amount it can contain inside. It is often used as an example when explaining why a cell can divide.



Cells divide by two processes called mitosis and meiosis. All cells in the body divide by the process of mitosis, except for sex cells. Sex cells divide by the process of meiosis.

Before cell division occurs, cells enter interphase. During interphase, many new organelles, such as ribosomes, are formed. This causes the cell to grow in size. As a result, the cell divides.


Correct answer: surface area:volume ratio

What are some products we get from fermentation?



Basically bread, alcohol and cider.


FERMENTATION: The chemical breakdown of a substance by bacteria, yeast, or other microorganisms, usually involving effervescence and the release of heat.

"There are three basic forms of fermentation:

lactic fermentation; when yeast and bacteria convert starches or sugars into lactic acid in foods like sauerkraut, kimchi, pickles, yogurt, and sourdough bread.

Fermentation in ethyl alcohol; where pyruvate molecules into starches or sugars are broken down by yeast into alcohol and carbon dioxide molecules to produce wine and beer.

Acetic acid fermentation of starches or sugars from grains or preserved fruits and sour-tasting spices. That's the difference, for example, between apple cider vinegar and apple cider. "


Many chemical reactions within a cell require a watery environment and certain organelles. The term for the location of the cell made of fluid (cytosol) and organelles is known as the A. Endoplasmic Reticulum
B. mitochondria
c. cytoplasm


Answer: cytoplasm


Cytoplasm is a thick solution that fills the cell and is surrounded by the cell membrane. The constituents of the cytoplasm are water, salts and proteins.

Cell organelles such as mitochondria, the Golgi body and the endoplasmic reticulum are found in the cytoplasm.

The cytoplasm may not appear to form any structure, but it provides the cell with its rigidity and structure.

Many of the body's chemical reactions take place in the cytoplasm.

The answer is C, the cytoplasm

Why is ATP necessary for everyday life?



ATP keeps our nerves firing and our hearts beating. It is the "energy currency" of our body. It is the main energy currency not only of our cells, but of all forms of life on the planet. All cells make it (it doesn't travel from cell to cell) and they use it to power almost all of their processes.
