Triglycerides are neutral fats that form from one glycerol molecule and three fatty acids. Phospholipids make up most of the cell membrane. Steroids have a backbone of four carbon rings and include cholesterol and sex hormones like estrogen.

Triglycerides are a type of neutral fat that is composed of one glycerol molecule and three fatty acid chains. They are the main constituent of vegetable oils and animal fats and are stored in adipose tissue as an energy reserve. Triglycerides play a crucial role in human metabolism as a source of energy and also serve as insulation and cushioning for organs. When the body needs energy, triglycerides are broken down into fatty acids and glycerol through a process called lipolysis. These fatty acids can then be used as an energy source by the body's cells.

Phospholipids are a type of lipid molecule that forms the main structural component of cell membranes. They are composed of a glycerol backbone, two fatty acid chains, and a phosphate-containing group. The fatty acid chains are hydrophobic, or water-repelling, while the phosphate-containing group is hydrophilic, or water-attracting. This unique structure allows phospholipids to form a lipid bilayer, with the hydrophobic fatty acid chains on the inside of the membrane and the hydrophilic phosphate-containing groups on the outside, facing the aqueous environment both inside and outside the cell. This creates a selectively permeable barrier that controls the movement of molecules and ions into and out of the cell. Phospholipids also play a role in cell signaling and can act as precursors for important signaling molecules such as second messengers.

Neural transmission across a mammalian synapse is accomplished by the release and binding of neurotransmitters. When an action potential reaches the end of an axon, neurotransmitter-containing vesicles fuse with the presynaptic membrane and release the neurotransmitters into the synaptic cleft.

The neurotransmitters diffuse across the synaptic cleft and bind to specific receptor proteins on the postsynaptic membrane, which triggers a change in the postsynaptic neuron's membrane potential.

This change can either excite or inhibit the postsynaptic neuron, depending on the type of neurotransmitter and receptor involved. After binding, neurotransmitters are either degraded by enzymes or reabsorbed by the presynaptic neuron, which terminates the signal.

The new plant produced by asexual reproduction through a rhizome will be genetically identical to the parent plant.

This is because asexual reproduction does not involve the fusion of gametes or the mixing of genetic material from two parents. Instead, the new plant grows from a part of the parent plant, with the same genetic information. Therefore, the traits of the new plant will be identical to those of the parent plant, including its physical characteristics, growth habits, and any traits that are determined by its genes.

This type of asexual reproduction is commonly seen in plants such as bamboo, ginger, and mint, which can spread rapidly through the growth of rhizomes. While asexual reproduction may limit genetic diversity.

The mRNA transcript is the single stranded copy of the template strand of DNA that is used to translate the genetic code into proteins.

The mRNA transcript is complementary to the template strand, meaning that it contains the same base sequence but with the opposite orientation. In this case, the template strand is 3'-CGAAGCGGA-5', so the mRNA transcript would be 5'-GCUUCGCUC-3'.

The mRNA transcript is synthesized from the template strand of DNA during the process of transcription, which is the first step in gene expression. In transcription, DNA is used as a template to produce a complementary RNA molecule.

The RNA polymerase enzyme binds to the DNA and reads it in the 3' to 5' direction. It then synthesizes a complementary RNA molecule in the 5' to 3' direction. The mRNA transcript that is produced is then used as a template for protein synthesis.
