Answer:
D -- ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential
Explanation:
Substrate- level phosphorylation is the synthesis of ATP from ADP by the transfer of phosphoryl group from a substrate with high phosphoryl group potential to the ADP molecule.
In substrate-level phosphorylation, the donor is a phosphorylated intermediate molecule with a high phosphate transfer potential and it is a way through which phosphate in introduced into a molecule, the other two ways are oxidative phosphorylation and photophosphorylation. In substrate-level phosphorylation, a PO4^2- is transferred from a phosphate intermediate (substrate) to ADP to form ATP. Phosphorylase and kinases are enzymes involved in this reaction. An example is the reaction in glycolysis which involves phosphoenolpyruvate and ADP to form Pyruvate and ATP. This is to ensure adequate supply of energy to cells and also during anoxia so as not to make mitochodria strain the glycolytic ATP reserves.
Answer:
b. True
Explanation:
Behavioral ecology is a science that studies animal behavior, considering its evolutionary and ecological bases, in which through experiments it seeks ways to show the evolutionary / adaptive causes of behaviors. Ecoetology deals with functional questions about behavior, how a behavioral pattern contributes to the survival chances of an animal or group of animals and their reproductive success. In addition, behavioral ecology is a meeting point for the study of behavior, ecology and evolution, in which ecology is the stage on which the animal must perform its behavior, and evolution in which organisms will be selected for having higher behaviors. success.
For this reason, we can conclude that the study of behavioral evolution, emphasizing the role of ecological factors as agents of natural selection, is known as behavioral ecology.
The answer is Adrenaline
Adrenaline is a stress hormone secreted by the adrenal glands and some other neurons when a person is frightened, excited or generally in stress.
It prepares our body for it's 'fight or flight' mechanism and tightens muscles for exertion.
After a bank robbery, most people feel a rush of adrenaline.

!!!!!!!!!!!!!!!!!!!!!!!!!!
The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.
In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.
The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.
These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.
