The different atoms are being put together in a chemical compound.
What is a Chemical compound?A chemical compound may be defined as any form of substance that is composed of similar types of molecules comprising atoms of two or more chemical elements. These compounds have specific characteristics based on their appearances and chemical structure.
These different atoms are linked together covalently to each other in a linear or somehow branched chain in order to construct chemical compounds. Such chemical compounds are derived as pure substances.
Chemical compounds are derived in such a way that when two or more elements of either similar or diverse characteristics are combined through a chemical reaction. Such types of compounds are definitely formed with the help of numerous chemical bonds.
Therefore, the different atoms are being put together in a chemical compound.

What kind of mineral ID is this?
please hurry !! thank you :)
Answer:
Cleavage and Fracture
Explanation:
Cleavage is the way a mineral breaks. Many minerals break along flat planes, or cleavages—some in only one direction (like mica), others in two directions (like feldspar), and some in three directions (like calcite) or more (like fluorite). Some minerals, like quartz, have no cleavage. Cleavage is a profound property that results from a mineral's molecular structure, and cleavage is present even when the mineral doesn't form good crystals. Cleavage can also be described as perfect, good or poor.

The structures that are found in eukaryotes, but not prokaryotes are:
Golgi bodyCilia. Both prokaryotic and eukaryotic cells contain cytosol and cell membrane structures.The Golgi apparatus is known as a cellular organelle whose function is to handle the proteins synthesized by the endoplasmic reticulum.
It is found in eukaryotic cells and is responsible for completing the production process of certain proteins.
Cilia are a series of short and numerous mobile extensions of the plasma membrane that line the cell surface of some eukaryotic cells.
Prokaryotic cells form living unicellular organisms, they present their genetic material dispersed in the cytoplasm, because they lack a cell nucleus.
Its cell membrane is responsible for delimiting the organism, which also lacks any type of organelle or cell divisions.
Therefore, we can conclude that the structures that are found in eukaryotes, but not prokaryotes are: Golgi body and Cilia and both prokaryotic and eukaryotic cells contain cytosol and cell membrane structures ..

Describe a non-biological hierarchy that exists in everyday life and how it relates to a biological system.
Answer:
A non-biological hierarchy could be the way the military is organized, with the soldiers at the very bottom and the big commanders on top. (I don't know the specific names for each of them) This relates to a biological heirarchy since the smaller, sadly less important things are at the bottom, like atoms and soldiers, and each group of soldiers makes a regiment (which would be a molecule), then a battalion (which would be a cell), then so on. (I dont know the order of the groups but you can look it up)

This is a timeline depicting the development of atomic ___________. What word should be used to fill in the blank? Support your choice with evidence. A) Law. At each interval on the timeline, scientists described the patterns they saw in both atomic and subatomic structure. Eliminate B) Law. Scientists used observation, experimentation, and mathematical models to explain atomic stricter and the behavior of subatomic particles. C) Hypothesis. Scientists conducted experiments at each interval. They made educated guesses regarding atomic structure and then experimented to support or rejected the hypotheses. D) Theory. At each interval on the timeline, scientists made observations and conducted experiments to explain how atoms and/or subatomic particles behaved in order to determine atomic structure.
Answer:
Subatomic particle, also called elementary particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons. But these basic atomic components are by no means the only known subatomic particles. Protons and neutrons, for instance, are themselves made up of elementary particles called quarks, and the electron is only one member of a class of elementary

Theory. At each interval on the timeline, scientists made observations and conducted experiments to explain how atoms and/or subatomic particles behaved in order to determine atomic structure. Let's take one example: Rutherford's gold foil experiment. Based on observing the behavior of alpha particles directed at a gold foil screen, Rutherford determined that an atom consisted of mostly empty space, with all of its positive charge concentrated in its center in a very tiny volume, surrounded by a cloud of electrons. Yet, further experimentation eventually lead to another model and another theory of atomic structure.

In trying to prove continental drift, Alfred Wegener used evidence from long ago to show that in the distant past, similar animal species lived in places that are ______today. For example, fossils of the________ were found in India, Africa, and Antarctica.
Wegener used Gondwana glaciation evidence, lithological and structural evidence, plates fitting together, and paleontological evidence to prove his theory. 1) separated 2) Lystrosaurus.
What evidence used Wegener to prove his theory?Since Wegener’s theory about continental drift was seriously criticized, he used a list of 10 pieces of evidence proposed by the geologist Du Toit that supported his theory.
The list includes Gondwana glaciation evidence, lithological and structural evidence, plates fitting together, and paleontological evidence.
Among the paleontological evidence, plant and animal fossils from the same species were found in currently separated continents. This distribution suggests the existence of a big unique supercontinent where these species used to inhabit.
For instance,
Glossopteris (fern) impressions are widely distributed in determined areas of Africa, South America, India, and Australia. Terrestrial vertebrate fossils also support the theory. The presence of Triassic tetrapods in all continents suggests terrestrial corridors between landmasses.⇒ Lystrosaurus ⇒ Triassic reptile ⇒ Found in Africa, India, and Antarctica
⇒ Mesosaurus ⇒ Triassic reptile ⇒ Found in South America and Africa
⇒ Cygnonathus ⇒ Triassic reptile ⇒ Found in South America and Africa
Finding these fossils on current different continents suggests that these landmasses were once together, and these species used to live in the same region.
With time, continents diverged and got separated by the ocean. The region where these species used to live got divided and fossils got separated.
In trying to prove continental drift, Alfred Wegener used evidence from long ago to show that in the distant past, similar animal species lived in places that are _separated_today. For example, fossils of the_Lystrosaurus_ were found in India, Africa, and Antarctica.
