I am pretty sure the answer is meteorology.
Enveloped viral membranes are generally (C)lipid bilayers with associated virus-specific (C)glycoproteins.
Viruses are intracellular parasites that hijack the cellular machinery for their own replication. Therefore, an essential step in the viral life cycle is the transfer of the viral genome into cells. Enveloped viruses (viruses with a lipid envelope) use a two-step process to release their genetic material into the cell.
It first binds to specific surface receptors on target cell membranes and then fuses with these. Viruses and cell membranes. This last step can occur at the cell surface or after internalization of the virus particle by endocytosis or another pathway (such as micropinocytosis).
Strikingly, the virus-cell-membrane fusion process proceeds along essentially the same intermediate steps as other membrane fusions that occur, for example, in vesicle fusion at neural synapses or cell-cell fusion in yeast mating. Fusogens, special viral proteins, facilitate the fusion of viruses and cell membranes.

According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust<span>.</span>
C) the phases are there for the cell to grow and mature properly ( much like a human) - if they don’t grow properly they won’t be able to reproduce.
Austin who was securely attached in Mary Ainsworth's theory of mother-infant attachment likely showed confidence in his caregiver's ability to protect him.
Options to this question were not provided. However, it is worthy to note that Mary Ainsworth's theory of mother-infant attachment classifies the relationship that children have with their caregivers as; Secure, Resistant, and Avoidant.
The Securely attached children are distressed when their mother is absent, they avoid strangers when their mother is not around but become friendly to strangers when their mothers are present.
They are also happy when their mother is around.
Generally, these sorts of children are confident and exhibit high self-esteem. So, Austin must have displayed some of these qualities.
