What type of chemical bond exists between two water molecules
Hydrogen bonds, type of chemical bond exists between two water molecules.
What is a chemical bond?A chemical bond is what binds atoms in molecules together. Electrical forces between positive charge atomic nuclei and negative-charged electrons form bonds. A chemical bond is a long-lasting attraction between ions or atoms that allows molecules and crystals to form.
Hydrogen bonds arise between neighboring water molecules' hydrogen and oxygen atoms. A hydrogen bond is formed by the attraction of individual water molecules. A water molecule is made up of two hydrogen and oxygen atoms atom, with one partly positive hydrogen atom connected to a more highly electronegative atom.

A student was asked to prepare a model of the rock cycle as it moves matter slowly through the Earth. The student creates a model,
as shown here. In order to revise the model, how should the lettered components be modified in order to create an accurate model?
Select all choices that apply
es )
A)
Letter A should represent igneous rock that is extruded from magma,
B)
Letters A and B should both be igneous rock, which is found near the
Earth's surface.
C)
Letters and B should be sedimentary rock, which is found under layers of
other materials
D)
Letter C should represent metamorphic rock which changes composition
under heat and pressure.
E)
Letter B should represent sedimentary rock that is buried by layers of sand
and deposited material.
Answer:
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.
Explanation:
Igneous rock comes from magma/lava. Sedimentary rock is buried as layers are deposited. The metamorphic rock is formed when one type of rock changes from one form to another. The single letter options are all right here.
The Rock Cycle is related to transformation of three basic Rock types into one another through the Plate tectonic activity, along with weathering and erosional processes. Hence Correct options are A, D, and E.
The Rock CycleIt is a phenomenon through which three basic types of Rock transformed into one another. These three types of Rock are Igneous, Metamorphic, and Sedimentary rocks.
Therefore, to prepare a model which shows Rock Cycle, student need to have three types of Rock as mentioned in option A, D, and E.
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.

Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Una persona sana necesita 1500 cal diarias para mantener su peso y su actividad rítmica normal ¿Cuántos J se obtendrá en 18,5 horas?
Answer:
4838J se requieren en 18.5 horas
Explanation:
Para resolver esta pregunta debemos, primero, hallar la cantidad de calorías necesarias para 18.5h (Ya sabemos que para 24 horas se necesitan 1500 calorías). Después, este resultado debemos convertirlo a Joules (1cal = 4.184J):
Calorías en 18.5h
18.5h * (1500cal / 24h) = 1156.25cal son requeridas en 18.5 horas
Joules requeridos:
1156.25cal * (4.184J / 1cal) =

Answer: fertilization
Explanation:
Answer:
Answer is D. Fertilization
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.
