Answer:
Red blood cells are adapted to their function by:
1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.
2) They are small and flexible so that they can fit through narrow blood vessels.
3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.

The answer is A
Because that would be the correct angle at the degree point which is pointing toward the top right
The right answer is D.
Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.
The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).
Answer:
Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events.
Explanation:
To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events."

"A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off."
