The answer is class and family.
<span>Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:</span>
<span>1. Domain: Eukarya</span>
<span>2. Kingdom: Animalia</span>
<span>3. Phylum: Chordata</span>
<span><u>4. Class: Mammalia</u></span>
<span>5. Order: Primates</span>
<span><u>6. Family: Hominidae</u></span>
<span>7. Genus: Homo</span>
<span>8. Species: Homo sapiens</span>
Hydrogen bonds are classified as weak because they are formed fast, but they also break easily under normal biological conditions.
Weak bonds can be easily broken, but this is extremely important because they are in bold in biological systems. For example, they help to decide and stabilize the shapes of water molecules.
Telomerase in lay terms is the aging protein and eventually stops the replication process
It is very true that masculinity and femininity are very strongly dependent on the society in which these terms are used. While there are genetic differences underlying the phenotype of being more masculine (having a bigger jaw, more hair on the body), there are also a lot of societal factors determining what is considered to be masculine and what feminine in a society.
