There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.
<h3>Features associated with each of Earth's four spheres.</h3>
<h3>Hydrosphere </h3>
It is the set of all the water on the planet, including those that form clouds.
<h3>Lithosphere</h3>
The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.
<h3>Atmosphere</h3>
It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.
<h3>Biosphere </h3>
It is the part of our planet that can support life
<h3>Internal processes</h3>
The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.
With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.

Answer:
some molecules pass
Explanation:
The ability of a membrane to pass or not to pass a substance is its permeability (permeability).
Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.
The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.

The developing organism is a fetus.
The best answer is D.
The mass number of an element is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu.
The nucleus of an atom is made up of protons and neutrons. Both these two types of particles are almost the same size. Almost all the mass of an atom (99%) is in the nucleus. Atomic mass therefore is really a measure of the size of the nucleus.
