Folding is responsible for compressing successive strata in the earth. Therefore, option (D) is correct.
What is folding ?The process of folding happens when tectonic processes put stress on a rock, but the rock does not break as a result of the stress. As the exposed faces of the folded rocks are worn away by erosion, this can result in a wide variety of landforms. Folds that resemble an arch are called anticlines, and folds that resemble the letter 'U' are called synclines.
This takes place deep within the earth, where the rocks are subjected to intense pressure and the temperature is much higher. Rocks that have been folded frequently occur in mountain ranges such as the Himalayas, the Alps, and the Scottish Highlands.
Therefore, option (D) is correct.

what are two ways that a cell can move a substance against its concentration gradient
Final answer:
Cells can move substances against their concentration gradient primarily through active transport and the use of carrier proteins or pumps, both of which require energy from ATP.
Explanation:
The question asks about two ways that a cell can move a substance against its concentration gradient. One primary way is through active transport, where the cell utilizes energy in the form of adenosine triphosphate (ATP) to move substances from an area of lower concentration to an area of higher concentration. The most common example of active transport is the sodium-potassium pump, which moves sodium out of cells and potassium into cells against their respective concentration gradients.
Another method involves the use of carrier proteins or pumps that also require energy from ATP to function. These proteins bind to the substance to be transported, undergo a change in shape that allows them to carry the substance across the cell membrane against the gradient. This mechanism is critical for maintaining the necessary concentrations of ions and other substances within the cell, despite passive movements that may tend to equalize concentrations across the membrane.

If the earth's mantle were completely solid, _________plates could not move around
If the earth's mantle were completely solid, tectonic plates could not move around.
What are tectonic plates?Tectonic plates are defined as a scientific theory that describes how the Earth's underground movements result in the formation of significant landforms. The fundamental landforms are thought to be the result of the Earth's subsurface motions, according to the scientific theory of plate tectonics. By explaining a wide range of phenomena, including as mountain-building events, volcanoes, and earthquakes, the theory, which became firmly established in the 1960s, revolutionized the earth sciences.
The heat generated by nuclear reactions taking place inside the planet's center causes the plates to move periodically toward and occasionally away from one another. Tectonic shift is another name for this movement.
Thus, if the earth's mantle were completely solid, tectonic plates could not move around.

Explain why cells are so small, considering the relationship between surface area and volume for objects of different sizes but similar shapes
Explain like a 6th grader would
Cells are small to ensure efficient transport of materials in and out of the cell. The relationship of surface area and volume impacts this, as a larger cell would have a smaller surface area relative to its volume, making transport less efficient.
Explanation:Cells are small because it makes it easier for materials to move in and out of them. This is because of the relationship between surface area and volume in objects. If a cell were to grow larger, its volume would increase at a much faster rate than its surface area. This would make it harder for materials to pass through the cell membrane quickly enough to meet the cell's needs.
For example, imagine if you're trying to touch every square inch inside a tiny room vs a huge gym. The gym will be a lot harder to cover thoroughly and quickly, right? It's the same for cells - keeping them small ensures everything inside can be reached quickly and efficiently.

How is geologic time organized on the geologic time scale?
A. Millennia and then smaller periods based on geologic and biologic events that occurred.
B. Eras and then smaller millennia based on geologic and biologic events that occurred.
C. Periods and then smaller eras based on geologic and biologic events that occurred.
D. Eras and then smaller periods based on geologic and biologic events that occurred.
Answer:
D. Eras and then smaller periods based on geologic and biologic events that occurred.
Explanation:
Geologic time corresponds to a chronological scale that encompasses the billions of years of planet Earth, from its origin to the present day. Geologic time is represented on the geological time scale and is divided into four units, namely: eons, ages, minor periods and epochs. This division is based on geological and biological events that have occurred since the formation of the earth to the present day.
We need to distinguish between the geological timescale and the historical timescale. Geologic time refers to the process of the emergence, formation and transformation of planet Earth. Historical time, in turn, refers to the emergence of human civilizations and their capacity for written communication.
Geologic time is organized into eons, which are divided into eras, then periods, epochs, and ages, marking major events in Earth's history, including changes in geology, climate, and evolution of life.
Geologic time is organized on the geologic time scale by dividing Earth's history into divisions based on major changes in geology, climate, and the evolution of life. This classification starts with the largest unit, eons, which are divided into eras. Each era is further subdivided into periods, and then periods may be further split into epochs and ages. An example of these divisions is the Phanerozoic Eon, which includes the Mesozoic Era, within which is the Cretaceous Period. This system of organization helps geologists and other scientists to understand and communicate information about the Earth's vast history with greater precision and context.

What are conductors like this flannel shirt,iron skillet, copper pipe, and oven mitt
Iron skillet and copper pipe are conductors, while flannel shirt and an oven mitt are insulators.
Thermal conductors are materials that transfer heat well due to the movement of free electrons or atomic vibrations. Metals such as iron (in the skillet) and copper (in the pipe) are excellent thermal conductors, explaining why they're also good electrical conductors. This is linked to the high density of free electrons in these metals, which allows them to transport thermal energy efficiently. Examples of thermal conductors include silver, copper, gold, and aluminum, which are all noted for their ability to conduct electricity as well.
Conversely, materials like the flannel shirt and oven mitt are thermal insulators. Thermal insulators are materials that do not conduct heat effectively, which can be due to their lack of free electrons or their structure that obstructs heat transfer. These are often used to prevent the transfer of heat, keeping us warm or protecting us from heat, as with an oven mitt. The handles of cooking utensils are typically made from poor thermal conductors to prevent burns when handling hot cookware.

If scientists wanted to learn more about evolutionary history, they would study all but one of these molecules. Which biological molecule would NOT offer much information about the history of life?
Phospholipids
Explanation;Nucleic acids are among the four major Biomolecules, others being proteins, lipids and carbohydrates. Nucleic acids are divided into two; RNA and DNA.By studying information about nucleic acids between organisms scientists are able to establish the evolutionary origin among organisms. DNA molecules are fundamental molecules in organisms since they carry genetic information in living organisms. DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms.Many organisms have distinct DNA sequences, however, animals may share some specific types of genes which are similar genetically in the sequences of DNA.Proteins on the other hand are formed as a result of gene expression, therefore, proteins may be used to establish information about the gene sequences and more so the DNA. thus proteins may be used to establish evolutionary history among various organisms.Answer:

How do I defuse this until I reach equilibrium across the membrane?? Picture below
Final answer:
To reach equilibrium across a membrane via osmosis, water moves through a semipermeable membrane from high to low concentration until the concentrations are equal, and equilibrium is achieved when net movement stops.
Explanation:
To defuse across the membrane until equilibrium is reached, you need to understand the process of osmosis. Osmosis is the movement of water molecules through a semipermeable membrane from an area of higher water concentration to an area of lower concentration. This movement continues until the concentration of water is equal on both sides, and at that point, equilibrium is achieved. In the provided U-tube scenario, with pure water in one arm and a glucose solution in the other, osmosis causes water to flow towards the glucose solution. To prevent the net flow of water, pressure can be applied on the glucose solution side equal to the osmotic pressure of the solution. Equilibrium is reached when no net movement of water occurs across the membrane and the levels in the arms stop changing.

nuclear power plants and geothermal power plants both use what
Final answer:
Both nuclear and geothermal power plants use steam turbines to convert heat into electricity, with the difference being the heat source: natural geothermal energy for geothermal plants and nuclear fission for nuclear plants.
Explanation:
Nuclear power plants and geothermal power plants both utilize steam turbines to generate electricity. In a geothermal power plant, the Earth's internal heat is harnessed to produce steam, which is then used to turn turbines and create electricity. Nuclear power plants generate steam through the heat produced by nuclear fission, which similarly drives turbines to produce electrical power.
Both methods are rooted in converting thermal energy into mechanical, and eventually, electrical energy, but the source of the thermal energy differs. Geothermal plants take advantage of the Earth's natural heat, while nuclear plants rely on heat from controlled nuclear reactions.

The elements are exist in nature in the combined and the free state. The metals and non metals may combine with the other elements in the nature.
Lithium, potassium and sodium are the highest reactive element. If they present in the free state, they can explode in the air catches fire easily. This is the main reason that they never found in the free state in the nature.
what does a kangaroo lack that a mammal such as a dog and cat have
The answer should be:
Placenta
If you'd like to know why:
The gestational period of kangaroos and other marsupials is not very long. Although they do give birth to live young, they give birth early. The off-spring is essentially just an embryo when the mother gives birth and it just latches on the nipples and develops for weeks to months.
Note: Its not really that they do not have a placenta, but theirs are just very different. Placentas in other mammals provides nutrients and blood supply to the fetus internally, but in marsupials, the nutrients provided in the womb comes from the yolk of the ovum, which serves as the placenta.
the answer is placenta.
