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.

Enzyme is a biocatalyst type of protein which can increase the rate of chemical reaction by reducing activation energy.
What are the properties of an enzyme ?Enzymes are protein catalysts which enhance the rate of biochemical reactions, it is pH-specific, catalyze both forward and reverse type of biochemical reaction but do not determine in which direction the reaction goes.
An enzyme have active site where the substrate bound to form desired product and the enzyme increase the rate of reaction by reducing the activation energy.
Several factors which shows their effect on the action of the enzyme like heat, temperature and varying pH, it shows absolute, relative, group, stereo-specificities and regulatory function.
The Physical properties of enzyme include act as colloid and inactivated below boiling point of water, are thermos-labile which can withstand temperatures of 100 degrees.

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)

There is no cause; genetic material should be floating around the cell in this manner.
Answer:
B. The nucleus is damaged.
Explanation:
Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles. DNA is present in the nucleus of the cell. If the nuclear membrane is ruptured/damaged then the nucleoplasm along with the DNA will openly float around the cytosol.
Answer: The nucleus is damaged.
Explanation: The nucleus is supposed to keep genetic material (DNA) housed within its membrane-bound structure, but in this cell, the genetic material is openly floating around the cell's cytosol. Have a nice day :)

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 ..

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
Explanation:
because it is
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.

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.
