Answer:

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

Answer: The enzyme is a catalyst that speed up the rate of the reaction.

Explanation:

The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

Answer:

When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.

Explanation:

The answer is B: It swells.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Answer:

The name of the element is carbon, there are 6 protons, and nitrogen has a smaller atomic number.

Explanation:

The atomic number of carbon is 6, not 12.

The atomic mass of carbon is 12.01g, not 12.

It does have six protons, it has a larger atomic number (6) than nitrogen (5) and it is called carbon.

Answer:

Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.

Explanation:

Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

The study of magnetic domains is defined as the micro magnetics. The Magnetic domains are outside of a magnet is not true. The correct option is C.

A magnetic domain is defined as a region within a magnetic material in which the magnetization is in a uniform direction. This indicate that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

The magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, etc. The domains are found to be oriented randomly if there is no external magnetic field.

Thus the correct option is C.

The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.

Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.

SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.

Intercambio de oxígeno y dióxido de carbono

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.

La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.

Intercambio de gases entre las alveolas y los capilares

Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. As eukaryotes, both fungi and plants have membrane-bound nuclei, which contain DNA condensed with the help of histone proteins.
