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

Answer:
Force
Explanation:
Answer:
the amount of inertia and object has depends on its mass
Explanation:
If you increase the force on an object, its acceleration increases.
if the object has a greater mass we can conclude the speed will go slower dur to inertia.To increase acceleration of an object, you reduce its mass or increase the applied force.

amin acids are used to build
Answer:
PROTEINS!
Explanation:
Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They're needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters.
Answer:
Proteins
Explanation:
Amino acids are the monomers, or the building blocks of proteins. There are 20 different amino acids that can make up proteins. The ribosomes in a cell perform protein synthesis and create proteins by assembling the amino acids, according to the DNA's genetic code. The proteins created are used for structure, growth, repair, maintaining pH, balancing fluids and more. In addition, they can be used as enzymes and hormones.
Infectious diseases are caused by organisms called pathogens. Pathogens can be bacteria, viruses, fungi, or protists. One common disease caused by a fungus is
A) the flu.
B) HIV/AIDS.
C) athlete's foot.
D) Parkinson's disease.
Answer:
C. Athletes Foot
Explanation:
Infectious diseases are caused by organisms called pathogens, and the pathogens can be bacteria, viruses, fungi, or protists, and one common disease caused by a fungus is athlete's foot, which is option C.
What is an athlete's foot?Athlete's foot is a fungal infection of the skin that affects the feet, and it is caused by a group of fungi called dermatophytes, which thrive in warm and moist environments such as locker rooms, public showers, and swimming pools. These fungi grow on the outer layer of the skin, and they are able to penetrate the skin through small cracks or cuts, and the symptoms of athlete's foot can vary, but they often include itching, burning, and scaling of the skin on the feet. In some cases, blisters or ulcers may also form. Athlete's foot can be treated with over-the-counter antifungal creams or prescription medications if the infection is severe.
Hence, one common disease caused by a fungus is athlete's foot, which is option C.

Answer:
An increase in the number of snakes
Explanation:
From the food web, the only way for frog population to increase is:
1) increase of cricket population. (increased food source)
2)decrease of hawks population (less predator)
An increase in snake population will result in mice population to fall as more snakes will hunt and feed on the mice. This causes lesser mice to feed on grasses. Resulting in increased food for crickets. As time passes, due to sufficient food, cricket population will increase which in turn increases the amount of food available for frogs to eat.
Assuming the number of predators remain constant and amount of crickets (food) increases, more frogs will survive to maturity and reproduce, causing the amount of frogs to increase.
Answer:
<1> an increase in number of snakes
Taking into account that a ecosystem is a food chain and animals increase and decrease depending on what they eat off of other living things. The increase in the number of frogs will occur, this is due to the diagram that is included and helps support answer 1.

Description of cell
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
During interphase, the cell copies its DNA in preparation for the second stage of meiosis.
Prophase is the first stage of cell division, in which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
Metaphase is the second stage of cell division in which the chromosomes become attached to the spindle fibers.
Anaphase is the third stage of cell division, in which the chromosomes move away from one another to opposite poles of the spindle.
Telophase is the fourth stage of cell division, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
Cytokinesis is the division of a cell at the end of mitosis or meiosis that separates the cells into two individual daughter cells.

Imagine that a clam accumulates one unit of mercury in its body from the water it lives in. How many units of mercury would a stingray accumulate if it eats 50 clams a day for 10 years, assuming no mercury is lost between the clams and stingray?
Answer:
182,500 units.
Explanation:
The answer would be 182,500 units of mercury.
Assuming there is an average of 365 days in a years, 10 years is therefore equal to:
10 x 365 = 3650 days.
The stingray eats 50 clams per day. Hence, the total number of clams that would have been eaten in 10 years equals:
3650 x 50 = 182,500 clams
Each clam accumulated 1 unit of mercury in its body from the water it lives in and there is no loss of mercury between the clam and the stingray. Hence, the total number of units of mercury the stingray would have accumulated in 10 years equals:
182,500 clams x 1 unit = 182,500 units of mercury.

in what way are carbohydrates and proteins similar?
Answer:
The body uses three main nutrients to function— carbohydrate, protein, and fat. ... Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.

The blood in the lungs contains less oxygen and more carbon dioxide than the air.explain why oxygen moves from the air to the blood and carbon dioxide from the blood to the air
Explanation:
To sustain life, the body must produce sufficient energy. Energy is produced by burning molecules in food, which is done by the process of oxidation (whereby food molecules are combined with oxygen). Oxidation involves carbon and hydrogen being combined with oxygen to form carbon dioxide and water.
