Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
The missing part of the question that is a group of statements is given as follows:
A. Earth is the only planet that changes structure.
B. Earth is the only planet that turns around in space.
C. Earth is the only planet that is mostly covered with water.
D. Earth is the only planet that is mostly made from rocks.
Answer:
The correct answer is - option C. Earth is the only planet that is mostly covered with water.
Explanation:
Earth is the only planet in our solar system that has liquid water, and it covers 75% of the total surface of the planet that gives it a unique identity as the blue planet of the solar system.
There are some other differences as well like plate tectonics, atmosphere and life make earth totally different from other planets.
Thus, the correct answer is - option C. Earth is the only planet that is mostly covered with water.
Your body detects a change in temperature before it goes to the brain then to the vessels so the answer is C! :)
Answer:
Explanation:
Observation and experimentation. It is part of the scientific method. It begins as Observation, Hypothesis, Experiment, Data Analysis, Conclusion.
