Enzymes are considered catalysts, they help reactants and can be used over and over
Answer:
The correct answer is insight learning.
Explanation:
A kind of problem-solving or learning, which takes place instantaneously by comprehending the various aspects of an issue in spite of going through trial and error procedure is termed as insight learning. The given case is a clear illustration of insight learning. This form of learning takes place if one finds a novel way to solve an issue without the help of any other elements.
The individual in the given case used the help of a cut potato to collect the broken pieces of a lamp, which is an illustration of insight learning. The person has used his instinct and has not used any outside source for doing what he had done.
Answer: Option C
Explanation:
The amitochondriate eukaryotes may have genes that have been derived from purple alphaloproteobacteria because they do not have the mitochondria which is needed to optimize energy production in the presence of oxygen, can live and exist in a condition with little to no oxygen which is a characteristic of proteobacteria and hence are anaerobes obtaining energy by anaerobic respiration. They may have also undergone the endosymbiont theory but due to their environment which has little to no oxygen. They do not have a need for the mitochondria organelle and in the process lose this organelle.
Answer:
C) B. subtilis can produce endospores which are resistant to the effects of UV.
Explanation:
Bacillus subtiles -
Bacillius subtiles bacteria is a gram - positive , found in soil and in humans in the gastrointestinal tract .
It is in rod shape , with tough and protective endospore , so it can tolerate the extreme temperature and environmental conditions .
B. Subtiles can produce endospore when cultivated , and these are resistant to the UV light .
and the E . Coli can also produce endospore when cultivated , but these are not resistant to the UV light .
There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.
Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.
Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
