Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. Oxygenic functions as a counterbalance to respiration; it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere.
Answer:
increase because the number of there predators the grouper is decreasing so its A
Answer:
It activates Cdc25, which in turn activates more M-Cdk
Explanation:
Cyclin are enzymes that regulate cell cycle progression by the activation of cyclin-dependent kinases (CDKs). These cyclins have no enzymatic activity on their own but they can activate Cdks by binding and phosphorylating them. CDKs can be activated by phosphorylation of activating sites and/or dephosphorylation of inactivation sites. Moreover, M-phase cyclins are cyclins that form M-CDK complexes in order to modulate the cell's entry into mitosis. Cdc25 is a phosphatase involved in the eukaryotic cell cycle which is well-known to regulate the entry into and progression during S (DNA Synthesis) phase and mitosis. In this regard, it has been shown that mitotic phosphorylation of Cdc25 by M-Cdks increases its intrinsic phosphatase activity, thereby Cdc25 is able to remove inhibitory phosphates from M-Cdk and, consequently, activate more M-Cdks.
Answer:
The attenuation system would respond more to histidine (His) than to tryptophan (Trp) levels
Explanation:
In genetics, the attenuation system refers to the process of control which is responsible for triggering premature termination of transcription in bacterial operons. In bacteria, the process of attenuation is characterized by the presence of an attenuator, which is a stop signal sequence found in the leader mRNA. The tryptophan (trp) operon, which is a cluster of genes responsible to encode the components required during the production of tryptophan, is controlled by the attenuation system. When there is a high tryptophan level, the ribosomes are able to translate an attenuator sequence, thereby resulting in termination of transcription. The attenuation system also controls the synthesis of other amino acids including histidine (His), phenylalanine (Phe) and threonine (Thr).
