We have 20 different amino acids in our bodies.
Answer:
The hypothesis can be made as follows:
' If there are less or no estuaries in a river, then there will be more erosion at the shorelines.'
A hypothesis is a tentative statement which can either be supported through experiments or proven to be wrong.
In the following scenario, we can conduct experiments by taking into observation those rivers which have estuaries and those which do not have estuaries. We can then compare the erosion of the shorelines of the rivers to validate our hypothesis.
Answer:
125 molecules
Explanation:
Between two amino acids , one water molecule is eliminated and a peptide bond is formed. When 250 amino acids are joined to form a polypeptide , 125 molecules of water will be removed.
That is, 250/2=125
Answer:
All options are correct, that is, they would all be correct for osteoarthritis.
This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.
Explanation:
Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.
The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).
This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".
Answer:
A) drive reduction
Explanation:
Motivation is the urge that fuels and directs human with the energy to accomplish a given task. Motivational theory is accustomed with the role of searching for what drives individuals to work towards a goal or a task.
The drive reduction theory explains physiological ideology required bring out an aroused tension state that motivates an organism to satisfy the need.
Instincts Theory reflects innate and fixed pattern of complex behavior in animals. For example, making holes of crabs for safety.
Optimum Arousal Theory drive people to engage in certain activities in the quest to keep up with an optimum level of physiological arousal.
Hierarchy of motives: According to Maslow's pyramid, hierarchy of motives is explained based on need to satiate or quench the least physiological needs in order to be active before subsequent level needs.
