In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. ... Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
Answer:
The thief of the money is that person who steals money.
Explanation:
The thief of the money is that person who steals money. The thief of the money can be find out through investigation and searching the criminal through evidences. The main motive of thief for stealing the money to fulfill the basic needs of his family such as food, clothes and others etc. Some thief steal money for fulfilling their dreams of becoming rich and attain higher status in the society. Our government also responsible in this crime because people usually become a thief due to no employment or source of money.
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
Answer: D. 100%
Explanation:
One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).
The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).
When both parents are crossed, the possible genotype outcome is
B B * b b
Bb Bb Bb Bb
Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44
Answer is 100%
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
