It is <u>true </u>that i<span>n operant conditioning, many complex behaviors are learned through shaping.
This means that you learn many new things through consequences that you experience. So, for example, when you're a kid, you are constantly being told not to touch a hot stove. But given that you are small and inquisitive, you still touch it and burn your hand. After that, you learn that touching something hot is going to hurt you, so you learn not to do it through a consequence.</span>
Answer:
The Pacific ocean
Explanation:
The Pacific ocean is about 50.1 percent of the world's oceanic water.
Answer: cell
Whole body respiration reflects the process of cellular respiration that takes place in the cell.
Explanation:
Cellular respiration is defined as the oxidation of organic food substances within the cell leading to the release of energy, carbon dioxide and water.
It can be represented by the equation:
C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (in form of ATP)
Thus, the main purpose of cellular respiration that takes place in a cell is to generate energy required by the whole body.
Answer:
How do proteins adopt and maintain a stable folded structure? What features of the protein amino acid sequence determine the stability of the folded structure?
Proteins are formed by three-dimensional structures (twisted, folded or rolled over themselves) determined by the sequence of amino acids which are linked by peptide bonds. Among these bonds, what determines the most stable conformation of proteins is their tendency to maintain a native conformation, which are stabilized by chemical interactions such as: disulfide bonds, H bonds, ionic bonds and hydrophobic interactions.
How does disruption of that structure lead to protein deposition diseases such as amyloidosis, Alzheimer's disease, and Parkinson's disease?
The accumulation of poorly folded proteins can cause amyloid diseases, a group of several common diseases, including Alzheimer's disease and Parkinson's disease. As the human being ages, the balance of protein synthesis, folding and degradation is disturbed, which causes the accumulation of poorly folded proteins in aggregates, which can manifest itself in the nervous system and in peripheral tissues. The genes and protein products involved in these diseases are called amyloidogenic and all of these diseases have in common the expression of a protein outside its normal context. In all these diseases, protein aggregation can be caused by mere chance, by protein hyperphosphorylation, by mutations that make the protein unstable, or by an unregulated or pathological increase in the concentration of some of these proteins between cells. These imbalances in concentration can be caused by mutations of the amyloidogenic genes, changes in the amino acid sequence of the protein or by deficiencies in the proteasome.
Explanation:
Answer:
Answer is true.
Explanation:
The absence of photosystem ii in thechloroplasts of the photosynthetic organisms can be detected by testing for the release of O2 in the light.
Note that these organisms still survive without the photosystem ii.
