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.

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.

Entre las células, aquellas que presentan cloroplastos con clorofila pueden ser catalogadas como...… A) ...Heterótrofas B) ...Carnívoras C) ...Autótrofas D) ...Herbívoras

Answers

Respuesta:

La respuesta correcta es: C) Autótrofas.

Explicación:

La clorofila es un pigmento verde que se encuentra en las cianobacterias y en células vegetales, dándoles a las plantas y algas su característico color. Se encuentra dentro de los cloroplastos.

La clorofila es una molécula de muchísima importancia para llevar a cabo la fotosíntesis, un proceso clave en la vida de las plantas y cianobacterias, ya que es la forma en la que obtienen los nutrientes que requieren para su supervivencia. El hecho de realizar fotosíntesis es lo que convierte a estos seres vivos en autótrofos, lo que significa que elaboran su propio alimento orgánico a partir de sustancias inorgánicas.

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.

Whats the meaning of life. It's clear that the lives of many creative artists are being transformed by digital technology. But competing schools of thought cite the very same technology in support of strikingly different conclusions.One group, for example, says the ability to widely distribute the best performers' products at low cost portends a world where even small differences in talent command huge differences in reward. That view is known as the "winner take all" theory.In contrast, the "long tail" theory holds that the information revolution is letting sellers prosper even when their offerings appeal to only a small fraction of the market. This view foresees a golden age in which small-scale creative talent flourishes as never before.Long-tail proponents often portray best-selling entertainment as lowest-common-denominator compromises whose only real advantage is lower cost made possible by large-scale distribution and sales. If technology makes scale less important, they argue, people will turn to the more idiosyncratic offerings that they really prefer. In principle, at least, this creates exciting new possibilities for small-scale sellers.In practice, however, winner-take-all effects still appear to dominate. Long-tail proponents predict that the least-popular offerings should be capturing market share from the most popular. But as Anita Elberse, a professor at the Harvard Business School, recounts in her 2013 book "Blockbusters", the entertainment industry's experience has been the reverse. Digital song titles selling more than one million copies, for example, accounted for 15 percent of sales in 2011, up from 7 percent in 2007. The publishing and film industries experienced similar trends.What's happening? One possibility is that today's tighter schedules have made people more reluctant to sift through the growing avalanche of options confronting them. Still, the growing market share of top sellers doesn't invalidate the promise of small-scale creative energy. Using big data, producers can now take aim at highly idiosyncratic buyers, and online searches help many such buyers find just the quirky offerings they're seeking.Your 3-5 sentence summary: The corrupt practice of ___(s) to free souls from purgatory taught that salvation could be bought.natural rightsdeismBiblephenomenongovernmentindulgence Find the position vector of a particle that has the given acceleration and the specified initial velocity and position.a (t) = 8ti + sintj + cos2tk, v(0) = i, r(0) = jr(t) = ?(b) On your own using a computer, graph the path of the particle.
