In what aspect the enzyme is different from other catalysts ? help please
Answer:
Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds.

Compare and contrast the burning of a Cheeto with the cellular respiration that
happens in your body.
Answer:
Cellular respiration is similar to combustion because both reactions rely on fuel (reducing and oxidizing agents) to start the reaction; the difference is that in cellular respiration, enzymes are used during the reaction. Both result in smoke (CO2 and H20) and energy.

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.
Why do you seldom see fossils in metamorphic rocks?
Answer:
Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.
Explanation:
Fossils are found in metamorphic rocks because metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.
What are metamorphic rocks?Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes.
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

*Ways we turn hydropower into energy we can use:
ways we can turn hydropower into energy: so one way were able to turn hydropower into energy is by using hydraulic turbines, using the turbine and mechanical energy the moving water spins a turbine and creates mechanical energy which is the converted into electricity.
The process usually takes place at hydropower plants, to tell you a bit more the falling water contains what we call kinetic energy which is what actually makes up the mechanical energy
The whole process takes place when water is released from a upper reservoir into the lower reservoir.
NEED HELP ASAP: List two ways in which the atmosphere would be impacted in the absence of the biosphere. Use complete sentences.
Answer:
If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.
There would be no negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.
Hope it help!
There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.
What is biosphere?The biosphere is basically comprised up of the areas of the Earth where life can be found.
The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.
Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.
The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.
Thus, this way, the atmosphere would be impacted in the absence of the biosphere.

AsUsing the word "niche” in your answer, explain why this species may have a
higher probability of becoming endangered than a species that eats ten species of plants.
In interspecies competition, two species use the same limited resource. Competition has a negative effect on both of the species (-/- interaction).
A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of).
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources).
Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

The diagram shows a process that takes place in certain organisms.
Which statement correctly identifies and describes the process taking place?
1- The process is cellular respiration in which chemical energy is being converted to light energy.
2- The process is cellular respiration in which light energy is being converted to chemical energy.
3- The process is photosynthesis in which light energy is being converted to chemical energy.
4- The process is photosynthesis in which chemical energy is being converted to light energy.
Answer:
I'm going to have to say 2
Explanation:
I'm not sure about photosynthesis because it's not making any glucose, or it doesnt show that in the diagram, but it is making oxygen which is a chemical reaction because it cant go back to carbon dioxide through the plant.
The process that takes place in certain organisms is photosynthesis in which light energy is being converted to chemical energy. Thus option 3 is correct.
what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts

The graph below represents the effect of enzyme concentration on the reaction rate.
Based on this graph, what can you conclude about the relationship between enzyme concentration and the rate of starch chemical reaction? (ASK 1a1)(DOK1)
Question 4 options:
a. The reaction rate decreases as the enzyme concentration increases
b. The reaction rate increases as the enzyme concentration decreases
c. The reaction rate increases as the enzyme concentration increases
d. The reaction rate is indirectly proportional to the enzyme concentration
Answer:
C
Explanation:
Increasing enzyme concentration will speed up the rate of a reaction, as long as there is substrate available to bind to.
Rate of reaction is directly proportional to the enzyme and substrate concentration. Therefore, option (C) is correct.
What is enzyme- substrate complex ?
An enzyme-substrate complex is what happens when a substrate attaches to an enzyme's active site during a chemical process. Aspects including temperature, pH, co-factors, activators, and inhibitors can affect an enzyme's activity.
A substrate is placed into the active site of the enzyme, or the location where weak bonds can form between two molecules. An enzyme substrate complex is created, and the enzyme's pressures on the substrate cause it to react and turn into the reaction's intended product.
Therefore, option (C) is the correct option as long as there's enough substrate for enzyme to bind and convert to product.

During the Devonian period of Gondwanaland what were the two organisms that thrived?
A) algae and Trilobites
B) land invertebrates and dinosaurs
C) conifers and early mammals
D) angiosperms and humans
E) marine invertebrates and land plants
PLS HELP ASAP
Answer:
about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.
