Simple. Air has mass. And if air has mass it also has weight. You can feel air when the wind blows. Or do an experiment. Weigh an empty container. Then pump it to a vacuum. Weigh it again. The difference is the weight of the air inside.
Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it. A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure
Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related
Fertilization refers to the process of two gametes of opposite sex uniting (option C).
<h3>What is fertilization?</h3>

Therefore, it can be said that fertilization refers to the process of two gametes of opposite sex (male and female) uniting.

Answer:
Climate change can melt ice in cold regions, and because ice is freshwater it can change the salinity of the oceans. Some marine animals may not cope with these conditions and may die as a result. This threatens biodiversity because there would be less species of marine life in our oceans.
