Answer:
nucleotide
.
Explanation:
The monomer that contains a base, sugar and phosphate group is a nucleotide.
Answer:
Stimuli must be sensed in order to respond.
Explanation:
Classical conditioning can be defined as a learning process which typically involves repeatedly pairing two stimuli: conditioned stimulus and unconditioned stimulus.
Simply stated, it is a learning procedure that helps us to understand when a neutral stimulus is paired with a conditioned response.
An example is the process of salivating in response to the aroma of a meal being prepared in the kitchen.
Also, operant conditioning can be defined as an associative learning process which involves reinforcing the strength of a behavior.
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Hence, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Answer:
Starvation causes a reduction in the <u>oncotic</u> pressure in the <u>cappilaries</u>, thus causing edema in the tissues.
Explanation:
Starvation is the extreme form of malnutrition, in which the caloric energy intake of an individual is much lower than required. The cells of the body start the breakdown of proteins, after the fat stores get exhausted. This reduces the oncotic pressure or the colloidal pressure in the blood vessels or capillaries of the body, thereby causing edema.
Edema is a medical condition, which involves the abnormal accumulation of fluid in the interstitium and cavities of the body.
Answer:
The HYPOTHESIS
Explanation:
In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.
The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).
