Answer:
Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

Answer:
Electricity flows by the movement of electrons through conductors. If a bird perches on a wire with two feet there is no motivation to go through the birds' body so electrons choose the path of least resistance and continue to flow along the wire.
Explanation:
The labeled anatomical features of the muscle filament are attached as an image.
Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.
- It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
- Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
- Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
- A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.
Thus, the correct labeled anatomical features of the muscle filament is attached as an image.

Answer:
This question lacks options, the options are:
A. Concentration of carbon dioxide in the air
B. Quality of nitrates in the soil
C. Wavelengths of light
D. Availability of water in the soil
The answer is B
Explanation:
Photosynthesis is the process whereby cells of autotrophic organisms manufacture their food in the presence of sunlight. The rate at which the process of photosynthesis occurs, however, is dependent upon certain factors including the concentration of reactants (water and carbon dioxide), availability of light source etc.
Among the options, the concentration/availability of light, carbon dioxide and water, which are key reactants of photosynthesis, will have greater effect on the rate at which the process occurs than the availability of nutrients (nitrates) in the soil. Hence, the quality of nitrates in the soil will have the LEAST effect upon the rate of photosynthesis in a geranium plant.
