it takes 25 min to cook 10 egg how long does it take to cook 20
Answer:
it takes 50 min
Explanation:
20 is twice of ten so if it take 25 min to cook ten then it is 50 min to cook 20.
Work for it:
10 x 2 = 20
10 eggs=10 min
25x2=50
Answer:
it takes 50 minutes to cook 20 eggs
Explanation:
ok first you have to see how long it takes 1 egg to cook so 25/10=2.5minute an egg then u multiply 2.5 x 20=50

There is a lot of talk about gaps in the fossil record. This means that we do not necessarily have fossils for every organism that has ever lived. What do you think could account for these gaps in the fossil record?
Answer:
Explanation:
The rate decomposition of dead remains, to a large extent, determines whether there would be fossils left of the organism after it has been long gone or become extinct. Environmental factors (such as harsh weather condition and early insect invasion of dead remains) could increase the rate of decomposition of dead remains which could really make it difficult for fossils to be available for such organisms under these factors (especially if the organism is restricted to a particular region by nature) .
Will lactase, the enzyme that digested the ice cream's lactose, also work on the lactose found in cheese?
Answer:
Yes
Explanation:
This is because lactose found in any dairy product will always have the same molecular structure. The lactase enzyme breaks down lactose because of how it is structured, so it does not matter where the lactose comes from.

Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults

Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.

taj incorrectly states that autographs are also known as consumers that need to feed on other organisms, including plants and animals, to gain energy. which of the following best describes consumers that feed on other organisms such as plants and animals for energy?
A. carnivores
B. trophic levels
C. heterotrophs
D. herbivores
Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.
What do you mean by herbivores?A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.
Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.
Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
A)Enzymes do not affect the energy of a reaction.
B)Enzymes slow down reactions so products can form.
C)Enzymes can be reused because they do not permanently bond with substrate.
D)Enzymes can only bind to other enzymes so the same product is formed each time.
Answer: C
Explanation: Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Enzymes can be reused because they do not permanently bond with substrate.
What are Enzymes?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Therefore, Enzymes can be reused because they do not permanently bond with substrate.

D. volume
Answer:
B
Explanation:
ganyan rin sagot ko sa module ko
When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.
What is Boyle's law?Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.
The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.
Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

Place the terms into the correct column that describes the reactions of photosynthesis.
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.

The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.
