Comparable sorts of plants and animals have been discovered in rocks of a similar age on the beaches of separate continents, implying that the continents were formerly linked. Fossils of Mesosaurus, a freshwater reptile, have been discovered in both Brazil and western Africa.
Plate tectonics is the hypothesis that the land masses on Earth are constantly moving. Alfred Wegener proposed the concept of continental drift, or the movement of Earth's land masses.Wegener proposed that the continents shifted toward and away from each other due to the Earth's rotation. Plates are constantly moving and reacting in a process known as plate tectonics.Mountains rise where plates press together, or converge, whereas continents fracture and seas form where plates pull apart, or diverge. The continents are embedded in the plates and drift passively with them over millions of years, resulting in profound changes in Earth's geography.Thus this is the meaning of Plate tectonic.

At sea level, water is a liquid at temperatures between 0 degrees Celsius and 100 degrees Celsius. If this temperature range was between 10 degrees Celsius and 100 degrees Celsius instead, which of the following statements would be true? a) The amount of liquid water would decrease, and the amount of solid water would increase b)The amount of liquid water would increase, and the amount of solid water would decrease c) The amount of liquid water would decrease, and the amount of water vapor would increase
If the temperature range was between 10 degrees Celsius and 100 degrees Celsius instead, the amount of liquid water would decrease, and the amount of solid water would increase. Option A.
Boiling and freezing points of waterWater molecules freeze at temperatures below zero degrees Celsius and boil from a temperature of 100 degrees Celsius and above.
This means that water will be liquid at temperatures between 0 and 100 degrees Celsius.
Now, if the lower boundary is increased - the freezing temperature is increased to 10 degrees Celsius. It means any water below 10 degrees Celsius will be frozen while the temperature range for liquid water has been narrowed.
In other words, the amount of liquid water would decrease, while the amount of frozen or solid water will increase.

What are the two different types of solids? How are their molecules arranged differently?
Based on how the particles are arranged, solids are classified into two types: crystalline solids and amorphous solids.
What is solid?Solid molecules merely pulsate and rotate in place. Ionic or strong covalent bonding holds solids together, and the attractive forces among atoms, ions, or particles in solids are very powerful.
A solid is a collection of atoms or molecules that are held together in such a way that they maintain a defined shape and size under constant conditions.
Solids are categorized into two types namely crystalline and amorphous. Amorphous solids are disordered, whereas crystalline solids are well ordered at the atomic level.
Thus, the two types of solids are crystalline and amorphous.

Answer:
vacuoles are water storage organelle in plant cells
Explanation:
it stores water for plants
In biology, vacuoles are membrane-bound organelles found in the cells of plants, fungi, protists, and some animal cells. They are essentially storage compartments within the cell that perform various functions depending on the type of cell and organism.
Vacuoles are typically larger in plant cells and often occupy a significant portion of the cell's volume. They can be classified into several types based on their functions:
Central Vacuole: Found in plant cells, the central vacuole is the largest and most prominent vacuole. It is responsible for maintaining turgor pressure, which helps to maintain cell shape and rigidity. It also stores water, ions, nutrients, pigments, and waste products.
Contractile Vacuole: Found in certain freshwater protists, contractile vacuoles are involved in osmoregulation. They collect and expel excess water from the cell to maintain a balanced internal environment.
Storage Vacuole: These vacuoles are involved in storing various substances such as nutrients, pigments, toxins, or waste products. In plants, they can store starch, proteins, and other compounds.
Lytic Vacuole: Found in some single-celled organisms like protists, lytic vacuoles function in intracellular digestion by containing enzymes that break down macromolecules or engulf and digest invading particles or organisms.
Vacuoles are essential for maintaining cellular homeostasis, regulating osmotic pressure, storing essential nutrients and ions, facilitating waste disposal, and providing structural support to plant cells. They also play a role in various developmental processes, such as cell growth and expansion.
