Answer:
Mark me as a Brainliest Please :)
Explanation:
The same principle works in all three cases, which is, the energy becomes heat and is extracted with the help of turbines in the same way that fossil fuels are burned. An electron-emitting neutron is equivalent to releasing kinetic energy. Histamine is a hydrogen atom with a helium nucleus.
Amino acids are linked together by peptide bonds to make proteins
The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.
2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.
3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.
4. C.
In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.
5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>
Gram's iodine reagent must be added to the plate before examination of amylase production.
Explanation:
The starch hydrolysis test is conducted to test the presence of the enzyme amylase in the test medium.
These are confirmatory lab tests done to detect and identify the presence of bacteria which can hydrolyze starch like amylose with the help of enzymes like amylase.
The test medium for this test is agar medium in a petri dish, where soluble starch is first added to initiate the microbial growth. Once incubation period of the microbes is over, dilute iodine solution is added to the petri dish in increased quantity. Iodine is a dye which helps to clearly identify the areas which are hydrolyzed by amylase and those which are not with the help of its color.
The statement about boiling points that is true is the boiling point of a substance is higher than its freezing point.
If something boils, it means it is really hot in there, and if it freezes, it is very cold.
