Answer:
It's D. acidic groundwater
Explanation:
d. Bogs are characterized by acidic groundwater.
What is a bog?
"A bog is a wetland of soft, spongy ground consisting mainly of partially decayed plant matter called peat."
What are characteristics of bogs?
"Bogs are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams."
How were bogs formed?
"Once plants began to decompose at the edge of a lake and once conditions were right for peat fen to form, the lakes slowly started to reduce in size. The fen continued to grow and over time a raised bog habitat began to form. The only water that is supplied to a raised bog is rainwater which is very low in nutrients."

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.

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 second structure shows the structure of carbon atom because atomic number of carbon is 6. Therefore, option B is correct.
What is carbon atom ?The carbon is an element denoted by symbol "C". The atomic number of carbon is 6. It belongs to the 14th period in the periodic table. Carbon is a nonmetal and the shape of carbon is tetravalent, so it has 4 electrons in the valence shell.
Carbon atom available in many forms, including carbon dioxide, coal, a cow, sugar and diamond. Carbon forms covalent bonds with atoms of carbon or other elements because it has 4 electrons in the valence shell.
In the second structure we see that there are four electrons are preset in valence shell ad the total number of electron present is six. Therefore, the second structure shows the carbon atom.

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.

Which of the following structures are found in eukaryotes, but not prokaryotes?
Choose 1 answer:
(Choice A) Golgi body
(Choice B) Cytosol
(Choice C) Cilia
(Choice D) Cell membrane
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 ..
