can multiple people use one brainly account at the same time on a computer??
Answer:
No
Explanation:
...............................
Multiple people cannot use one brainly account at the same time on a computer.
No, multiple people cannot use the same Brainly account at the same time on a computer. Brainly accounts are designed to be used by individual users and are intended for personal use. Each user should have their own separate account to access and interact with the Brainly platform. Sharing an account among multiple people simultaneously can lead to confusion, conflicts, and potential violations of the platform's terms of service. It is recommended that each person creates their own individual account on Brainly for a smooth and personalized experience.
Hence, multiple people can't access brainly at the same time.

What happens when molten material travels along the underside of the crust?
Answer:
Explanation:
The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.
Thus, magma rises from the bottom of the mantle towards the crust.

How do the particies in a liquid create surface
tension?
It's been a while since I've taken Chemistry but here's what I know:
There are small, weak bonds that form between water molecules. These bonds make it so liquid molecules (water, in this example) cannot move as freely as a gas, but their bonds aren't nearly as strong as a solid. The bonds are formed when a hydrogen atom is attracted to an oxygen atom (because they have an opposite charge). This bond plus the gas molecules hitting the water causes surface tension.
(Let me know if this is wrong and I hope you have a lovely day!!)
Where do most earthquakes occur? Where do most volcanoes occur? Why do they occur here?
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire
Explanation:
Answer:
Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

Explanation:

Among the following redox conditions those will produce a spontaneous reaction is The sum of the voltages of the half-reactions is positive.
What are redox reactions?Redox reactions are the reactions in which reduction reaction and oxidation reaction happens simultaneously. The term ‘redox’ is a short form of reduction-oxidation. All the redox reactions can be broken down into two different processes: a reduction process and an oxidation process.
The loss of electrons and the corresponding increase in the oxidation state of a given reactant is called oxidation. The gain of electrons and the corresponding decrease in the oxidation state of a reactant is called reduction.
For example-
H₂ + F₂ → 2HF
Hydrogen is added to Fluorine gas so Fluorine has been reduced but Hydrogen has been oxidised.
Therefore, Among the following redox conditions those will produce a spontaneous reaction is The sum of the voltages of the half-reactions is positive.

What is the purpose of a salt bridge?
O.
A. To supply energy for the reaction
B. To connect two electrodes
O C. To prevent charge buildup
O D. To dissolve metals into solution
Answer: B. To connect two electrodes
Explanation:
The salt bridge forms a connecting link between the two electrodes. The function of the salt bridge is not to supply electrons from one electrolyte to another but to maintain a constant balance of charge as the electrons move from one half of the cell to the another. The electrons from from negative electrode to positive electrode that is from anode to cathode.
Answer: C. To prevent charge buildup

Why cells are called "little giants"?
Answer:
Giant cell, also called Langhans giant cell, large cell characterized by an arc of nuclei toward the outer membrane. The cell is formed by the fusion of epithelioid cells, which are derived from immune cells called macrophages. Once fused, these cells share the same cytoplasm, and their nuclei become arranged in an arc near the outer edge of the cell. Langhans giant cells typically form at the centre of granulomas (aggregates of macrophages) and are found in the tubercle, or primary focus of infection, in tuberculosis, in lesions of syphilis, leprosy, and sarcoidosis, and in fungal infections.Large cells that form by fusion in reaction to the presence in the body of foreign substances differ from Langhans giant cells in that their many nuclei are scattered throughout the cell. In giant-cell tumours of bone and tendon the cells have many nuclei crowded together. The megakaryocytes, the normal bone-marrow cells thought to be the source of the blood platelets, are also called giant cells.

Which statements describe crossing over? Check all that apply. Crossing over occurs during prophase II of meiosis. Crossing over combines a sperm cell with an egg cell. Crossing over happens when pairs of chromosomes pair up. Crossing over ensures that a new cell is identical to the original cell. Crossing over creates new combinations of genes on chromosomes.
Answer:
Crossing over happens when pairs of chromosomes pair up
Crossing over creates new combinations of genes on chromosomes.
Explanation:
The correct answer would be that crossing over happens when pairs of chromosomes pair up, exchange chromosomal segments, and create new combinations of genes on chromosomes.
Crossing over occurs during prophase I of meiosis when homologous chromosomes pair up to form a tetrad. Paired chromosomes then exchange chromosomal segments containing genes leading to a new combination of genes on each chromosome. Hence, the resulting daughter cells are genetically different from the original cell.
