El melanismo industrial es el fenómeno genético por el cual lepidópteros que viven en zonas industriales tienen un color oscuro. Este fenómeno se debe a que la selección natural favorece un determinado genotipo.
La selección natural es el principal mecanismo por el cual las especies y los organismos evolucionan (cambian) para adaptarse a su ambiente.
La selección natural se define como la supervivencia y reproducción diferencial de los individuos mejor adaptados a su ambiente.
Este proceso (selección natural) tiende a modificar las frecuencias de génicas (alélicas) y genotípicas las cuales determinan los rasgos adaptativos a lo largo de las generaciones.
La selección direccional es un tipo de selección natural que tiende a favorecer a un sólo alelo a lo largo del tiempo.
En el melanismo industrial, los lepidópteros (polillas) que expresan el alelo que codifica para el rasgo fenotípico 'color oscuro' se ven favorecidos porque esta característica les permite mimetizarse en un entrono ambiental oscuro causado por la polución ambiental de zonas industriales.

All carbohydrates are made from smaller building blocks known as Blank Their main function is Blank. The elements found in carbohydrates include Blank
Answer:
All carbohydrates are made from smaller building blocks known as monosaccharides. Their main function is energy storage. The elements found in carbohydrates include Carbon, Hydrogen, and Oxygen
Explanation:
Carbohydrates are a fundamental organic compound that is essential to life. Their building blocks are known as monosaccharides, these are also known as simple sugars such as glucose. They all follow the same multiple of the unit C6H2O (1 C : 2 H : 1 O). We need to carbohydrates to store energy so that when we consume them we can perform cellular respiration, a highly precise process where we can break down glucose to form ATP for our body.

Explain what you think the quote "You are what you eat" means?
(Include the following vocabulary: macromolecule, carbohydrates, lipids, proteins, nucleic acids)
The term "You are what you eat" was coined due to the effects of the content of the food we ingest on the rest of our organism.
Food comes in an endless number of options, each of which contains numerous molecular compounds of varying kinds. Every molecular compound that we ingest through the food that we eat can have distinct effects on the body, some of these compounds include:
MacromoleculesCarbohydratesLipidsProteinsNucleic acidsMacromolecules are a class of molecules that encompass many others. Proteins and lipids are just some of the examples mentioned that fall within the class of macromolecules. Some macromolecules can be good for the body, such as proteins, whilst others can cause some negative effects as is the case with lipids.
Lipids are vital for the proper functioning of the body. Lipids provide a source of reserve energy and can regulate hormones, among other important functions. However, lipids can also be harmful to your health. Lipids provide reserve energy by being stored as fat. Excessive consumption of lipids can cause numerous health problems.
Carbohydrates are at the same level as lipids in terms of their effect on the body. Carbohydrates are sugars, which are necessary to include in a healthy diet, however, excessive consumption of carbohydrates can cause health issues ranging from diabetes to pancreatic failure.
Proteins are amongst the most essential macromolecules for the human body. They provide a variety of functions which include:
Maintaining pH levelsRepairing tissueAid in the production of antibodiesAllow metabolic reactions to take placeamong many others. This, along with nucleic acids are a prime example of "you are what you eat" in that those who consume more of these (coupled of course with proper exercise) tend to be healthier individuals.

The constant movement of particles when seen under a microscope is a very common observation known as Brownian motion.
All particles are made of atoms. Atoms are comprised of three components:
NeutronsProtonsElectronsthe first two comprise the core of an atom, surrounded by a cloud of electrons.
Though much too small to be seen without aid, these atoms do indeed possess mass and are capable of colliding with one another. Particles constantly collide with one another and are bounced in the opposing direction, over and over again. This is precisely what we observe under the microscope as particles bouncing around and is referred to as Brownian motion.

explain how a typical rib articulates with the vertebral column
The ribs are curved, flat bones which form the majority of the thoracic cavity. They provide protection to the internal thoracic organs and twelve pairs of ribs articulate with the vertebral column.
what is vertebral column?The vertebral column or spine or backbone, is a flexible column forms a part of the axial skeleton which is a characteristic feature of the vertebrates, placed dorsally and composed of 26 segmented units, called vertebrae.
It forms the central axis of the body skeleton and emerges from the neck at the base of the skull and extends upto the tail.
The vertebral column of human consists of 33 bones at birth, the lower 9 bones fuse into two separate bones and the upper 24 bones are separated and articulated by intervertebral disc during adult stage. T
The number of bones in the vertebral column is 26 where 7 are cervical vertebrae, 12 thoracic vertebrae, 5 lumbar, 1 sacral (fused) and 1 coccygeal (fused) vertebrae. T
