Answer:
Homeostasis es la constancia del Medio interno, aún frente a las variaciones del Medio externo
(Cannon). El Medio interno se relaciona con la complejidad de los seres vivos.
Según Teoría de la Evolución, el primer ser vivo surgió en el mar, formado por una sola célula, la cual
intercambiaba nutrientes y desechos metabólicos con su Medio externo.
De los Unicelulares evolucionaron los Pluricelulares, los cuales debían solucionar el problema del
intercambio de nutrientes, oxigeno y desechos de las células que se encuentran en su interior. De esta
forma se desarrolló un ambiente interno, que permitió la vida libre e independiente.
El Medio interno está representado por el Líquido extracelular que rodea a las células de los Pluricelulares,
con una composición estable que permite los intercambios metabólicos y la comunicación celular.
El 60 % del peso corporal humano es agua, la cual se encuentra distribuida en un 40% del peso corporal en
el Líquido intracelular y en un 20% en el Líquido extracelular.
Del total del Líquido extracelular un 80% corresponde al Líquido intersticial y un 20% al Plasma sanguíneo.
El Líquido intersticial o tisular debe mantenerse constante, para lo cual se requiere la ayuda del
Sistema circulatorio.
El Plasma sanguíneo intercambia oxigeno y nutrientes, dióxido de carbono y desechos con el Líquido
extracelular a nivel de los Capilares sanguíneos, debido a lo cual en ambos líquidos la concentración de
solutos es igual, a excepción de las proteínas.
Según Starling, existe un equilibrio entre el volumen de líquidos que sale del capilar arterial y el que
vuelve por los capilares venosos.
El Líquido intracelular varía de célula a célula del punto de vista cuantitativo, guardando similitud en la
composición celular desde el punto de vista cualitativo

Write a prediction that answers the lab question, "How are proteins built using the information provided by a molecule of RNA?" Remember, you are describing processes, so your prediction should include steps.
After transcription occurs the information for synthesizing proteins is stored in the messenger RNA. The messenger RNA contains the codon(three nitrogenous bases that code for one amino-acid). In the ribosome the codon binds to the anticodon(homologous to the codon) of the transfer RNA that carries the amino-acid. The mRNA contains information regarding the order of the amino-acids inside the peptide.
Answer:
RNA determines the sequence of amino acids in proteins and polypeptides by a two-step process: transcription of DNA produces mRNA in the nucleus, then translation of the mRNA to tRNA takes place in the ribosome in the cytoplasm.

Discuss the function of hemoglobin in human body and the consequences of hemoglobin
deficiency
Hemoglobin: The high iron-containing protein in red blood cells (RBCs) is known as hemoglobin. This gives the blood a red color.
It has two main functions: it carries oxygen from the lungs to tissues of the body, and it carries carbon dioxide from cells back to the lungs for excretion.
Functions of hemoglobin:
Hemoglobin is the main reason for the red color in our blood.Hemoglobin carries oxygen and carbon dioxide. Hemoglobin interacts with other ligands.Hemoglobin plays a crucial role in maintaining the shape of red blood cells.Consequences of hemoglobin deficiency:
Hemoglobin deficiency leads to having fewer red blood cells and causes anemia.It is found in red blood cells and acts as a carrier of oxygen and carbon dioxide.Low levels of hemoglobin in the blood cause parts of the body to function more slowly and weaken due to reduced oxygenation.Hemoglobin deficiency reduces the blood's oxygen-carrying capacity.

which of the following is not true regarding glycolysis? group of answer choices it is in both in aerobic and anaerobic respiration it occurs during fermentation it degrades glucose to co2 and h2o it occurs without oxygen it ends with the formation of an acid
Glycolysis is a metabolic pathway that occurs in both aerobic and anaerobic respiration, during fermentation, and without the presence of oxygen.
Glycolysis is a fundamental metabolic pathway that occurs in both aerobic and anaerobic respiration, allowing cells to break down glucose and generate energy. It also takes place during fermentation, a process that occurs in the absence of oxygen.
However, it is important to note that glycolysis does not directly degrade glucose to \(CO_2\) and \(H_2O\), which is a characteristic of aerobic respiration. Instead, glycolysis breaks down glucose into pyruvate molecules, generating a small amount of ATP and NADH.
Moreover, glycolysis does not end with the formation of an acid; rather, it produces pyruvate or lactate, depending on the specific conditions and organisms involved.

How would you be able to determine if the tn5 transposon you put into a bacterium integrated into the host genome?
To determine if the TN5 transposon integrated into the host genome of a bacterium, several approaches can be used like PCR amplification, DNA sequencing, Southern blot analysis, transposons rescue etc.
By employing these techniques, researchers can determine if the TN5 transposon integrated into the bacterium's host genome, allowing for insights into integration patterns and potential effects on the host. These are explained as follows:
1. PCR Amplification: PCR can be performed using primers specific to the TN5 transposon and the host genome. If the transposon has integrated into the host genome, PCR will yield a product representing the transposon-host DNA junction.
2. DNA Sequencing: Sequencing the PCR products or genomic DNA can confirm transposon integration. By comparing the obtained sequences with known TN5 and host genome sequences, the integration site can be identified.
3. Southern Blot Analysis: Genomic DNA is digested with restriction enzymes and probed with a TN5-specific labeled probe. This technique can detect transposon presence and provide information about integration patterns and copy numbers.
4. Transposon Rescue: Genomic DNA is isolated and subjected to a transposon rescue procedure. Circular molecules containing the transposon are generated and transformed into another bacterium for amplification and further analysis.
5. Transposon-Specific Assays: Utilize transposon-specific assays based on TN5 features. For instance, if the transposon carries a selectable marker, its presence can be assessed through appropriate selection methods to infer integration.

An early science that tried to correlate personality with measurements of parts of a person’s skull is known as ________.
An early science that tried to correlate personality with measurements of parts of a person’s skull is known as Phrenology
In order to anticipate mental characteristics, phrenology measures the size of bumps on the skull. It is predicated on the idea that the brain is the seat of the mind and that different parts of the brain have distinct, specialized tasks.
By the 1840s, phrenology had lost much of its credibility as a scientific hypothesis. This was only partially caused by mounting evidence that refuted phrenology. Phrenologists struggled to locate the mental organs and were never able to agree on the most basic mental organ counts, which ranged from 27 to over 40.

Lesson 02.01: Properties of Water
Water is a compound common to living things because it is essential for life. It is a major component of cells and plays a crucial role in many biological processes.
Hydrogen bonding is important to the properties of water. Water molecules are polar, meaning they have a slight positive charge on one end and a slight negative charge on the other. This polarity allows water molecules to form hydrogen bonds with each other. Hydrogen bonding gives water its high boiling point, high specific heat capacity, cohesion, and adhesion properties.
Many compounds dissolve in water due to its polarity. Water's polar nature allows it to form interactions with other polar molecules, such as salts and sugars, as well as with charged ions. The positive and negative ends of water molecules surround and separate the ions or polar molecules, effectively dissolving them in the water.
Lesson 02.02: Microscopes
Modern technology has greatly impacted the study of biology. Advanced microscopes, such as electron microscopes, have allowed scientists to observe structures at a much higher resolution and magnification than was previously possible. Techniques like fluorescence microscopy and confocal microscopy enable the visualization of specific molecules and cellular processes in living organisms.
There are various types of microscopes with different structures and functions:
Light microscopes: Use visible light to illuminate the specimen and produce an image. They are commonly used in educational and research settings and can magnify up to 1000x.
Electron microscopes: Use a beam of electrons instead of light to visualize specimens. They offer much higher magnification and resolution than light microscopes. There are two types: transmission electron microscopes (TEM) and scanning electron microscopes (SEM).
Scanning probe microscopes: Use a physical probe to scan the surface of a specimen. They can provide atomic-level resolution and are used in nanotechnology and materials science.
Lesson 02.03: Early Cells
The developments that led to the cell theory include:
Robert Hooke's discovery of cells in cork in 1665.
Anton van Leeuwenhoek's observations of microscopic organisms in pond water in the late 17th century.
Matthias Schleiden's and Theodor Schwann's formulation of the cell theory in the 19th century, stating that all living organisms are composed of cells, and cells are the basic units of life.
Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells lack a nucleus and membrane-bound organelles. Eukaryotic cells are generally larger and more complex than prokaryotic cells.
The cell membrane, also known as the plasma membrane, is a selectively permeable barrier that surrounds the cell. It consists of a phospholipid bilayer with embedded proteins. The cell membrane regulates the movement of substances in and out of the cell and plays a vital role in maintaining cell homeostasis.
Active transport requires energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Passive transport, on the other hand, does not require energy and involves the movement of substances along their concentration gradient, from an area of higher concentration to an area of lower concentration.

Explanation:
"Most bees gather only pollen or nectar. ... When her nectar “sacs” are full, the honeybee returns to the hive. Nectar is delivered to one of the indoor bees and is then passed mouth-to-mouth from bee to bee until its moisture content is reduced from about 70% to 20%. This changes the nectar into honey."
