Answer:
This is because the cell membrane is a partially permeable membrane, hence allowing the smaller molecules to enter it and larger molecules to be out. For example, protein is too large to enter the cell
Explanation:
Amphibians are referred to as the "planet's greatest survivors" because they have repeatedly avoided extinction over the course of 400 million years.
<h3>How did the amphibians survive?</h3>
Over the years, the amphibians have had to adapt to various surroundings. Small animals called amphibians require water or a moist environment to exist. This group of species includes newts, salamanders, toads, and frogs. All have extremely thin skin that allows them to breathe and absorb water. Additionally, amphibians have unique skin glands that create functional proteins.
According to fossil evidence, amphibians descended from lobe-finned lungfish about 365 million years ago. They were very successful since they were the first terrestrial vertebrates. Some of them were considerably bigger than modern-day amphibians. The predominant group of land vertebrates for more than 100 million years was amphibians.

Probaly abiotic would be the most likely answer in my opinion.
Answer: D. Atomic Number
Explanation:
Atomic number of an element is the number of protons in the nucleus of an atom the element. An atom has three fundamental particles: protons, electrons and neutrons. Protons and neutrons are found in the nucleus of an atom while electrons are found outside the nucleus. The atomic number of an element determines the properties of the element. No two atoms of different elements have the same atomic number, but two or more atoms of the same element can have the same atomic number but different atomic masses. When atoms of the same element have the same atomic number but different atomic masses, they are said to be isotopes.
