what evidence shows that biological molecules on earth form naturally?
Explanation:
La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.
Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.

Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.

The nucleus of the cell is similar to the_______ system of the body.
The nucleus of the cell is similar to the Neurological system of the body.
What is Nucleus?According to the Cell Biology, nucleus may be a membrane found in organism cells.
The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.
Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.
The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell
The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".
The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.
The nucleus is the largest organelle in animal cells.
For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
What is Neurological System or Nervous System of the body?The Nervous system could be a extremely advanced a part of associate degree animal that coordinates its actions and sensory data by sending signals to and from completely different components of its body.
In vertebrates it consists of 2 main components, the central system (CNS) and therefore the peripheral system (PNS). The CNS consists of the brain and neural structure.
The function of the system is to send signals from one cell to others, or from one a part of the body to others and to manage the body.
It will this by extracting data from the setting exploitation sensory receptors, causing signals that encrypt this data into the central system, process the data to work out associate degree applicable response, and causing output signals to muscles or glands to activate the response.

Why did the White House experience water damage ?
1.
It is made of granite which is strong.
2. It is made of sandstone which is very porous and is easily penetrated by rainwater
3. It is made of non-porous sedimentary rock
The White House building is made of sandstone which is very porous as a result water is easily penetrated inside it which causes damage and make the walls of building weak.
The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.
