Answer:
a. food and drink.
Explanation:
Maslow’s hierarchy of needs as represented by a pyramid, has the most fundamental and basic needs placed at the bottom, which are physiological needs. They are followed by safety, love and belonging, esteem, and self-actualization.
Physiological needs include food, drink, shelter. These are needs necessary and essential for physical survival that motivates human behaviors.
<em>Food and drink are the most basic or lowest-level need in Maslow’s hierarchy of human motives
.</em>
Answer:
This is an example of adaptation due to a progressive mutation
Explanation:
At the beginning, the bacteria can use the galactose as carbon source for it needs, but since this food is getting out in every new generation. The new generations can be adapted to survive with smaller quantities of galactose until there will be one generation that can survive with any galactose source, when this offspring reach the area of the plate without galactose, then it can be grown in ant area.
Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.
Answer:
Lysozyme is an enzyme that breaks down bacterial cell walls and is found in your tears, mucus, and saliva. A mutation occurs in the gene for lysozyme that results in a lysine (a positively charged amino acid) being substituted for an arginine (also a positively charged amino acid). Do you think that the mutant lysozyme will function similarly to the normal lysozyme?
No, because all changes in protein primary sequence result in functional differences
Explanation:
Protein sequence are known to be complimentary to each other, slight changes or sudden changes would affect the function as well as those work in antagonizing way with one another.
