Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

What ocean animals die from the earthquake in japan?

The earthquake and resulting tsunami in Japan in 2011 caused damage to marine ecosystems, resulting in the mortality of various ocean animals. Some of the species affected included fish, seabirds, marine mammals, and invertebrates like corals. The widespread destruction of habitats and disruption of food chains led to significant losses in biodiversity.

Which branch of science created the telescope?

The invention of the telescope is credited to the field of optics, which encompasses the study of light, vision, and the behavior of electromagnetic radiation. The first practical telescope was invented in the early 17th century by Dutch spectacle maker Hans Lippershey.

How did Darwin's finches help him find his theory of evolution?

The finches on the Galapagos Islands helped him, as they gave him the basis of his idea of natural selection, which was the backbone of his Theory of Evolution. The birds beaks had altered slightly to enable them to eat the various foods available on their respective islands. This observation then prompted Darwin to extrapolate the data, and say that these small changes could eventually result in a fish turning into a reptile.

How dry solid can be obtained from the liquid in which it is dissolved?

One way to obtain dry solid from a liquid is by a process called evaporation. This involves heating the liquid to allow the water to vaporize, leaving behind the solid component in its dry form. Another method is precipitation, where addition of a chemical can cause the dissolved solid to come out of solution and form solid particles that can be separated from the liquid.

What is a landform made by wind deposition?

A dune is a landform made by wind deposition, where sand is deposited and shaped into mounds or ridges by wind action. Dunes are commonly found in deserts and coastal areas where there is an abundant source of sand particles that can be easily transported by the wind.

When applying a force to make an object move why is it most effective to have the applied force amied directly at the objects center of mass?

Applying a force directly at the object's center of mass minimizes rotational effects, reducing the chance of the object spinning or deviating from the desired path, and allowing for efficient movement in a straight line. This is because the center of mass is the point at which the object's mass is evenly distributed, resulting in smoother and more predictable motion.

How does this natural phenomenon work?

Natural phenomena are occurrences in nature that can be observed and studied. They are often the result of various physical and chemical processes interacting in the environment. Scientists use observations, experiments, and theories to understand how these phenomena work and their impact on the world.

What process is most responsible for the existence of international culture?

Globalization is the process most responsible for the existence of international culture. It involves the exchange of ideas, values, and customs between different countries, leading to a blending of cultures on a global scale. This interconnectedness has resulted in a more unified and interconnected world culture.

Is it illegal to have an telescope in Australia?

I really doubt it. After thoroughly searching the internet for about 4 seconds,

I found a chain of stores offering telescopes and accessories for sale in Sydney,

Melbourne, Brisbane, Perth, Adelaide, and Tasmania. Either these guys are the

world's worst businessmen, or else telescopes are perfectly legal in Australia.

What would happen if you omitted methyl red in the reaction mixture?

If you omitted methyl red in the reaction mixture, you would not be able to visually monitor or detect the pH change in the reaction. Methyl red is a pH indicator that changes color in response to pH changes, so without it, you would not be able to accurately determine when the reaction has reached a specific pH endpoint.

What are the inner walls of the mitochondria called?

Its all called the mitochondria i think. I never learned other wise. I looked it up though and got that its called the inner membrane. I apologise if thats not overly helpful or not what youre looking for. Its the best i can do at 230

What are 3 distinguishing features of euglenophytes?

Three distinguishing features of euglenophytes are the presence of a pellicle (proteinaceous layer), two flagella for locomotion, and the ability to photosynthesize with chloroplasts derived from green algae through secondary endosymbiosis.

What are things that are noncellular besides cytoplasm?

Some examples of noncellular structures include the cell wall, extracellular matrix, and flagella. These structures provide support, protection, and movement to the cell.

Does condensation take place when particles leave a liquid and become a gas?

No, condensation occurs when gas particles lose energy and transition into a liquid state. The process involves the gas particles coming together due to cooling, which results in the formation of liquid droplets.

Divergent plate boundaries can create what two things?

they create trenches underwater, valleies and other things like the Great Rift Valley of the Marianis Thrench

How would removing heat from a system change its state or temperature?

Heat tranfer is the method used to do this. Removing the heat from a system changes its state by changing the molecular structure of the system being used. Say it is water(H2o), if heat is removed from water it changes the energy level of the molecules by removing energy and causing the molecules to hold close to eachother. This creates a solidifying effect creating ice. If the opposite is done and heat is added to water, energy is added. The molecules then are energized and get to the point of not being able to be close to eachother seperating and going off on their own. Thus creating steam.

What kind of test are there for a sedimentary rock?

Common tests for sedimentary rocks include grain size analysis, sedimentary structures observation, mineral identification, and porosity measurement. These tests help determine the composition, texture, and origin of the rock.

Which is smaller Cell Wall or nucleus or cytoplasm or mitochondria?

The mitochondria is the smallest among cell wall, nucleus, cytoplasm, and mitochondria. Mitochondria are tiny organelles found in cells that are responsible for producing energy in the form of ATP.

Black and white bees?

It is not actually a bee but comes from the wasp family; they're known as bald-faced hornets or Dolichovespula maculata (although they are called this, it is a misnomer as they really do belong to the wasp family).

What does arthopod mean?

Are the largest group of invertabrates.

the word 'arthropod' means 'jointed leg'.

their bodies are also divided into segments.

they rae supported by a hard skeleton on the outside on the body called an exoskeleton when they grow too big for their exoskeleton, they moult and grow a new one.

on their heads are feelers or antennae.

The arthropods are made up of 4 smaller groups;

1.crustaceans

2.myriapods

3.insects

4.arachnids

if u want any moe info about the 4 groups ask me

Are tigers multicellular or uncellular?

It's a mammal.... what do you think?

if you said unicellular, you need to think more about why you asked this question, if you said multicellular... why'd you even ask?

correct answer: Multicellular... there are no mammals that have only one cell count. infact there aren't too many animals that do even...

Give you some examples of camouflage?

Examples of camouflage include an octopus blending in with its surroundings by changing its color and texture, a stick insect resembling a twig to avoid detection by predators, and a snowshoe hare changing its fur color from brown in summer to white in winter to match its environment.

What is the opposet of Englsh?
