Amylase becomes denatured at a temperature of 80c. During an experiment to study the effect of varying temperatures on enzyme activity, amylase's reactivity with starch was measured at a body temperature of 37c and then again at an increased temperature of 42c. How would this increase in temperature affect the experiment?
Answer:
The rate of reaction will increase
Explanation:
Temperature is known to affect the rate of the reaction. Generally, chemical reactions depend on thermal activation. It means that an increase in temperature also increases the kinetic energy of the reactants. Increasing the temperature increases the reaction rate due to the increase in the number of molecular collisions between reactant molecules. The speed of a particle is directly related to its kinetic energy and thereby an increase in temperature also results in an increase in the amount of collisions between molecules per unit of time.
As CO2 concentration increases in this graph, how is average global temperature affected?
Answer:
increases as well
Explanation:
carbon dioxide and other greenhouse gases contribute to the effects of global warming

ATP is produced in all stages of cellular respiration. Which two statements describe the process of ATP synthesis in the electron transport chain?
A. The ATP synthase spins when the hydrogen ions rush past, acting as a "matchmaker" and grabbing another phosphate group to attach to an ADP molecule.
B. The high concentration of NAD+ acts as a catalyst to speed up the formation of ATP from ADP.
C. The high concentration of hydrogen ions in the intermembrane space allows them to diffuse across the membrane into the matrix.
D. The FADH2 synthase spins as the high-energy electrons rush past, synthesizing ATP from ADP.
Answer:
C. The high concentration of hydrogen ions in the intermembrane
Explanation:
Merry Christmas
The two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.
What is the significance of the hydrogen in the electron transport chain?In this electron transport chain process of cellular respiration, electrons are passed from molecule to molecule through a series of protein complexes in the inner membrane of the mitochondria, where ATP synthase is an enzyme located in the inner membrane that makes ADP into ATP.
Hence, the two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.

As we know that the leaves of plants are waterproof due to cuticle. On the same way, take some pieces of paper of leaf size and make them waterproof. after completion, put half of these paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof? Explain your observation and result with justifications
Answer:
its answer is:
No all the pieces of paper not remains waterproof. After making water into its pieces in the shape of leaves, it can't be able to defend water. As paper is non living thing and leave is part of living being so, paper is not waterproof but leaves is waterproof.

explain why plants do not burst when immersed in distilled water
Answer:
it becames turgid
Explanation:
Plant cells have plasma membrane and rigid cellulose cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. As the cell becomes turgid, the cell wall creates an inward force i.e wall pressure that prevents the cell from bursting.
Answer
According to EasyEliMu,
Plant cells have cells membrane and cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. ( This is the reason why plants do not burst!!! ) As cell becomes turgid, the cell created an inward force, wall pressure that prevents the cell from bursting. Isotonic solution- a solution which has the same concentration as the cell sap.

What is the role of RuBP? How is RuBP regenerated?
Answer: RUBP Regeneration refers to the cyclical process where the photosynthetic enzyme Rubisco fixes carbon dioxide into the sugars that fuel plant growth and productivity. Only one-sixth of the PGA carbon is converted to sugar—the rest of the carbon is used to recycle RuBP as the cycle continues.

At night, a land breeze forms because
A) water releases less solar energy during the day; warm ocean air moves into land.
B) land cools more quickly than water; cool land air moves to replace rising warm air over the water
C) land absorbs less solar energy during the day; cool land air moves to replace rising warm air over the water
D) water absorbs more solar energy during the day; cool land air moves to replace rising warm air over the water
Answer:
B) land cools more quickly than water; cool land air moves to replace rising warm air over the water
Explanation:
During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. ...

Hola, esto no es sobre la escuela, pero estoy desesperada: Mi gata ayer tuvo 5 crías que ya tomaron calostro, pero la gata se ve mal y muy cansada ,cabe aclarar que sus hijos están todo el día tomando leche pero la gata se ve mal y siento que no le va a alcanzar la leche, la quiero ayudar porque se ve muy mal, cansada y decaída. Me pueden decir algún sustento (casero o no) para poderles darles sin eliminar por completo la leche materna? Quiero que que la gata y sus hijos estén bien. Si me ayudan se los agradecería .
Answer:
Hola, para resolver tu problema debes tener en cuenta tanto a tu gata como a sus crías.
Primero, respecto a la madre, una buena alternativa serian inyecciones de vitaminas y suero, que la ayudarían a reponer energías y a generar más alimento para sus crías. Pero también la ayudaría a sentirse menos decaída, lo cual mejoraría su estado de ánimo.
Por el lado de las crías, si lo que deseas es que se alimenten por otra vía que no sea la de su madre, una alternativa ideal es la leche maternizada artificialmente, que es un alimento específico para gatos recién nacidos, aunque es bastante costoso de adquirir. Otra alternativa, ya casera, es hervir arroz, colar los granos y utilizar el agua en donde se cocinó como alimento para los cachorros. Obviamente, debes dejar enfriar el líquido, pero una vez a temperatura natural tendrá muchos nutrientes que habrá absorbido de los granos de arroz y servirá como sustituto de la leche materna.
