What process is taking place in the image below?
Answers
You can see in this particular structure, there is a hydrogen bond between a hydrogen on the hydronium ion and the oxygen on the other water molecule.
Hydronium ions don’t exist in on their own, they’re required to have some way of balancing the charge that comes from the additional hydrogen ion. This balancing is typically done by the water surrounding the hydronium ion (H3O+H3O+) since water will outnumber the amount of hydronium atoms by orders of magnitude (there’s a lot more water than ions).
The hydronium ion in cold water is typically surrounded by 6 water molecules (probably oxygen towards the extra hydrogen but I can’t access the journal to confirm). There are some other structures like the one above, and another called the Eigen cation where the hydrogen is at the center of four water molecules (one is technically the hydronium). There’s also a very large structure that’s called the magic structure that has a hydronium ion surrounded by twenty water molecules (it’s called magic because it’s extra stable for its size).

Who are the key players in dna replication
Answers
Hope this helps :)
The key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.
What is the role of enzymes in DNA replication?At the replication fork, the enzymes responsible for DNA replication work in concert to simultaneously synthesize the DNA's leading and lagging strands. The replication DNA polymerases (Polymerase III in E. coli) produce dimers to complete this activity.
The enzyme DNA polymerase, also referred to as DNA pol, is one of the main players. DNA pol I, DNA pol II, and DNA pol III are the three primary forms of DNA polymerases found in bacteria.
DNA pol III is currently understood to be the enzyme needed for DNA synthesis, whereas DNA pol I and DNA pol II are mostly needed for repair.
Therefore, the key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.

and cover the garden rows with black plastic. When it is spring and planting time, they plant seeds though holes they have poked in
the plastic. Why do the Roberts use the plastic covering?
A)
The black plastic keeps the weeds from growing in the bare soil.
B)
The black plastic keeps the soil warm so the seeds will grow in the spring,
The black plastic helps the organisms that live in the soil survive the
winter
D)
The garden space will be covered with grass and animals will graze in the
area.
Answers
Answer:
ANSWER IS A
Explanation:
A black plastic mulch conserves soil moisture by preventing it from evaporating. Only the exposed soil in the holes where the vegetable plants are growing lose water to evaporation. This means that more moisture is available in the surrounding soil for plant roots, and you spend less time on watering the growing crops.
Explain why the Roberts family uses plastic covering.
Autumn is the season when trees lose their leaves. That is the reason Roberts family pull up the dead plants and cover the garden rows with black plastic.Spring is the season of planting. It is a season when plants spring from the ground and trees come into blossom, following winter and preceding summer.The plastic covering prevents weeds from growing on the bare soil.Weeds are unwanted plants grown at a place at a period of time. Any plants that grows where it is not wanted is weed.Therefore,
The reason why the Roberts family uses plastic covering is because "The black plastic keeps the weeds from growing in the bare soil".

B. A predominance of slow-growing trees
C. A predominance of pine trees
D. Barren land
SUBMIT
Answers
The one that results in a woodland frequented by fire is predominance of slow-growing trees. The correct option is B.
What is woodland?A forest is frequently also referred to as "woodland." But most frequently, the phrase is used by geographers to refer to a forest with an open canopy.
The topmost layer of vegetation in a forest is called the canopy. The crowns, or tops, of trees make up this structure.
Woodland contains a wide variety of plant and animal habitats, some of which need management to be created and maintained.
The complete spectrum of plant life, including trees, shrubs, climbers, perennial herbs, bulbs, grasses, sedges, mosses, and lichens, make up woodland.
Predominance of slow-growing trees is the factor that leads to a woodland that experiences frequent fires.
Thus, the correct option is B.

how are Metamorphic rocks with fine grains made and how did the composition of the Earth’s atmosphere cause changes to form the rock over time.
Answers
Answer:
A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. ... A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals.
Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphism also happens when rocks are buried deeply during the process of mountain building. The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
