It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.

Mark this and return
Save and Fxit
Answer:
natural selection leads to evolution
Explanation:
Natural selection leads to evolution. Therefore, the correct statement is option A.
What is natural selection?Evolution is a result of natural selection. Natural selection is an evolutionary mechanism that rewards people with specific features that help them live and procreate more successfully than those lacking such traits. New species evolve as a result of an increase in the frequency of these favorable features in the population throughout time.
Natural selection is a major force behind evolution in this way. However, other processes, such genetic drift, gene flow, and mutation, can also lead to evolution.
Natural selection and evolution are separate but closely connected ideas. It is one of the mechanisms that propels evolutionary change through time; as such, it is a mechanism of evolution. It acts on the genetic variation present in a population, favoring traits that increase an organism's reproductive success in a given environment.
Therefore, natural selection leads to evolution.

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? osmosis passive transport active transport diffusion
Answer: Active Transport
Explanation: Active transport is the movement of a substance (proteins, enzymes, etc.) from one area of the cell membrane to the next during diffusion, so this would most be affected due to the kinds of substances being transported across the cell membrane and damage can have an impact.
Carrier proteins are involved in active transport. The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.
What are the carrier proteins?Carrier proteins are transmembrane molecules involved in active transport.
They carry molecules from one side of the membrane to the other side.
What is active transport?Active transport acts against the electrochemical gradient, so it does need the energy to transport substances.
It carries molecules from a low concentration side to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.

Which biomolecule do you think is most important in your diet? Why did you pick that biomolecule? Which biomolecule do you think is most important in cell function? Nutrition and snack foods A. List your three favorite snack foods. B Collect a nutrition label from each food. C. If any of the foods on your list don’t come in a package, you can look up the nutrition information on the Internet. D. Write a paragraph about each food. Is it a good source of carbohydrates, lipids, and protein? Would you consider this food healthy? Why or why not? 2. You may have heard the saying, “You are what you eat.” to explain what this statement means.
Answer/Explanation:
There is no single biomolecule that is most important in one's diet; however, proteins would be a fitting choice. This is because there are certain amino acids -- 9 in fact -- that our bodies cannot naturally produce and of which proteins consist. We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
A. Welch's, Oreos, Chips Ahoy
B. You should be able to do this.
C. Proves my point in B.
D. Yeah, generally the snacks I chose are not healthy, even Welch's fruit snacks. It's junk food and not high in protein. "You are what you eat" makes sense in the quite literal sense because your body mass, your health, and your overall physical attributes are determined by your diet, on top of exercise and your activities throughout your life.

What is the number of this particle in a phosphorus atom?
Ap ex
Answer:
Fósforo
Símbolo P, número atómico 15, peso atómico 30.9738. El fósforo forma la base de gran número de compuestos, de los cuales los más importantes son los fosfatos. En todas las formas de vida, los fosfatos desempeñan un papel esencial en los procesos de transferencia de energía, como el metabolismo, la fotosíntesis, la función nerviosa y la acción muscular. Los ácidos nucleicos, que entre otras cosas forman el material hereditario (los cromosomas), son fosfatos, así como cierto número de coenzimas. Los esqueletos de los animales están formados por fosfato de calcio.
Cerca de tres cuartas partes del fósforo total (en todas sus formas químicas) se emplean en Estados Unidos como fertilizantes. Otras aplicaciones importantes son como relleno de detergentes, nutrientes suplementarios en alimentos para animales, ablandadores de agua, aditivos para alimentos y fármacos, agentes de revestimiento en el tratamiento de superficies metálicas, aditivos en metalurgia, plastificantes, insecticidas y aditivos de productos petroleros.
De casi 200 fosfatos minerales diferentes, sólo uno, la fluoropatita, Ca5F(PO4)3, se extrae esencialmente de grandes depósitos secundarios originados en los huesos de animales y que se hallan en el fondo de mares prehistóricos, y de los guanos depositados sobre rocas antiguas.
La investigación de la química del fósforo indica que pueden existir tantos compuestos basados en el fósforo como los de carbono. En química orgánica se acostumbra agrupar varios compuestos químicos dentro de familias llamadas series homólogas.
Esto también puede hacerse en la química de los compuestos de fósforo, aunque muchas familias están incompletas. La familia mejor conocida de estos compuestos es el grupo de cadenas de fosfatos. Las sales de fosfatos constan de cationes, como el sodio, junto con cadenas de aniones, como (PnO3n+1)(n+2)-, que pueden tener de 1 a 1 000 000 de átomos de fósforo por anión.
Los fosfatos se basan en átomos de fósforo rodeados en una disposición tetraédrica por átomos de oxígeno, el miembro más pequeño de la familia es el anión simple PO3-4 (el ion ortofosfato). La familia de las cadenas de fosfato se basa en hileras alternadas de átomos de fósforo y oxígeno en que cada átomo de fósforo permanece en el centro de un tetraedro de cuatro átomos de oxígeno. Hay también una familia estrechamente relacionada de fosfatos cíclicos.
Una característica estructural interesante de muchos de los compuestos del fósforo conocidos es la formación de estructuras tipo jaula. Ejemplos de estas moléculas son el fósforo blanco, P4, y uno de los pentóxidos de fósforo, P4O10. Las estructuras tipo red son comunes; por ejemplo, los cristales de fósforo negro en que los átomos están enlazados unos con otros.
En la mayor parte de sus compuestos, el fósforo está enlazado químicamente a cuatro átomos inmediatos. Hay gran número de compuestos en los que uno de los cuatro átomos está ausente y en su lugar hay un par de electrones no compartidos.
Hay también unos cuantos compuestos con cinco o seis átomos unidos al fósforo; son muy reactivos y tienden a ser inestables. Durante los años 60 y 70, se prepararon muchos compuestos orgánicos de fósforo. La mayor parte de estas estructuras químicas incluye tres o cuatro átomos enlazados al fósforo, pero existen también estructuras con dos, cinco o seis átomos unidos a cada átomo de fósforo.
Casi todo el fósforo utilizado en el comercio está en forma de fosfatos. La mayor parte de los fertilizantes fosfatados constan de ortofosfato diácido de calcio u otofosfato ácido de calcio muy impuros, Ca(H2PO4)2 y CaHPO4. Estos fosfatos son sales del ácido ortofosfórico.
El compuesto de fósforo de mayor importancia biológica es el adenosintrifosfato (ATP), que es un éster de la sal, el tripolifosfato de sodio, muy utilizado en detergentes y ablandadores de agua. Casi todas las reacciones en el metabolismo y la fotosíntesis requieren la hidrólisis de este tripolifosfato hasta su derivado pirofosfato, llamado adenosindifosfato (ADP).
Efectos del Fósforo sobre la salud
El Fósforo puede ser encontrado en el ambiente más comúnmente como fosfato. Los fosfatos son substancias importantes en el cuerpo de los humanos porque ellas son parte del material de ADN y tienen parte en la distribósforo que es conocida. Cuando el fósforo blanco ocurre en la naturaleza este puede ser un peligro serio para nuestra salud. El fósforo blanco es extremadamente venenoso y en muchos casos la exposición a él será fatal. En la mayoría de los casos la gente que muere por fósforo blanco ha sido por tragar accidentalmente veneno de rata. Antes de que la gente muera por exposición al fósforo blanco ellos a menudo experimentan náuseas, convulciones en el estómago y desfallecimiento. El fósforo blanco puede causar quemaduras en la piel, dañar el hígado, corazón y riñones.

A plant grows faster and fuller due to large amounts of fertilizer. If the plant cross-pollinates with another plant later, how will the use of fertilizer on the parent plant affect the plant’s offspring?
Answer:
The answer is "C" because nothing that your parents do, unless it directly affects/changes the gametes, will pass down to the offspring. Fertilizer is like food, how much your parents have eaten in their childhoods will have no effect on if you are under or over weight. (Unless their weight was by a genetic cause, that might have been passed on to you.)
