Answer:
The correct answer is option - a virus.
Explanation:
Viruses are the infectious agents that are neither considered living nor nonliving organisms. The viruses possess the genetic material enclosed in the capsid made up of the proteins.
Genetic material or the genome of the viruses could be the DNA or the RNA as single or double-stranded forms. The viruses with RNA as genetic material termed as the adenoviruses such as tobacco mosaic viruses and HIV and others.
Thus, the correct answer is option - a virus.
Answer:
Stretching is a sign of growing, also known as having a growth spurt. Your body stretches in order to make room for things growing, for example, how a pregnant woman's stomach stretches to make room for her unborn baby.

Answer:
Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.
Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.
Explanation:
Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.
Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.
Answer:
Chemical bonds contain potential energy.
Explanation:
Chemical bonds always contain potential energy. The atoms of the bond want to move to a lower energy to become more stable.. The energy for breaking bonds only comes when stronger bonds are formed. This energy is used to tear apart the bonds holding the Hydrogen atoms together. The strength of the covalent bonds depend on the overlap between the valence orbitals of the bonded Atom.
