Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted?

Answers

Answer:

The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.

Leaving out metal can in the rain for weeks and weeks until it was very rusted, and then if we carefully weighing it again it can be found that the can weighs more because the rust deposited on the metal can adds more weight.

What is rust?

Rust is referred to as an iron oxide, and a form of corrosion which is caused by a chemical reaction which affects masses of iron and steel.

Once formed, rust starts to eat away at the metal, forming a flaky, orange red coating which weakens the iron. It occurs when the metal reacts with oxygen and water.

Las células en los tejidos epiteliales están fuertemente unidas a la lámina basal. ¿Qué tipo de proteínas están involucradas en este tipo de unión célula-matriz?

Answers

Answer:

integrinas y lamininas

Explanation:

Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.

Lizard is a poikilothermic animal because lizards are those animals that do not require a fixed body temperature, their temperatures can fluctuate with little to no adverse effects to their overall health.

Explanation:

A boxer has been jumping rope for an hour. His leg muscles are burning and
he feels weak. Which substance is the most likely
cause of the burning he
feels in his muscles?

Answers

Answer:

anaerobic respiration takes place when you demand your muscles to do vigorous work. normally, aerobic respiration takes place but when energy is needed immediately, anaerobic respiration takes place. during anaerobic respiration,the body produces lactic acid, which leads to the burning sensation. your lungs deliver oxygen to the muscles much slower than the rate you need, since you're putting your muscles through an extensive exercise, and this leads to muscle fatigue.

O D. Ban CO2 use

Answers

Answer:

C

Explanation:

The countries that signed the Kyoto Protocol agreed to reduce greenhouse gas emissions (C) particularly carbon dioxide emissions, in an effort to combat climate change.

What is Kyoto protocol?

The Kyoto Protocol is an international treaty under the United Nations Framework Convention on Climate Change that was adopted in 1997 in Kyoto, Japan (UNFCCC). The treaty seeks to address the issue of global climate change by establishing targets for reducing greenhouse gas emissions, specifically carbon dioxide emissions, from industrialized countries.

According to the Kyoto Protocol, developed countries must reduce their emissions by an average of 5.2% below 1990 levels by 2012. The protocol has been ratified by 192 countries, and signatories have implemented a variety of policies and strategies to meet their emissions reduction targets, including increased energy efficiency, increased use of renewable energy sources, and the implementation of emissions trading systems. The Kyoto Protocol is a significant step forward in terms of international cooperation and action on the critical issue of climate change.

Athletes require energy to move their body. What biomolecules directly supplies your muscles with quick energy, or ATP, when broken down?​

Answers

Answer : creatine phosphate

Creatine phosphate can be broken down in order to supply your body with ATP at a high rate, but it doesn’t last too long.

Creatine phosphate directly supplies muscles with quick energy, or ATP, when broken down.

Creatine phosphate is a phosphorylated creatine molecule. Muscles use stored chemical energy from the food we eat and convert it to heat and kinetic energy. Adenosine triphosphate is the source of energy used to power the movement of contraction in working muscles. However, ATP is not stored in large amounts in cells. So once muscle contraction begins, the process of making more ATP starts quickly. The muscle has three biochemical systems to produce more ATP for muscle contraction. One such biochemical system utilizes creatine phosphate.  Muscles have a little ATP in them that they can use immediately but it does not last long. So, all muscle cells have a high-energy compound called creatinine phosphate which is broken down to form ATP quickly.
