When talking about evolution, a good example is bacterial resistance to antibiotics.
We start with a bacteria colony, and in contact with antibiotics, most of them die.
Some of them in the colony do not die and took that antibiotic to create a mutation of its DNA to be resistance to that.
They evolved survive that antibiotic.
Answer:
Organism in a lichen that provides protection - algae
Organism in a lichen that provides nutrients through photosynthesis - algae
Branched growth form of lichen - fruticose
Leafy growth form of lichen - foliose
Small and flat growth form of lichen - crustose
Explanation:
<em>Lichens are composite organisms that are formed from symbiotic relationships between fungi and cyanobacteria/algae. The Green algae layer offers food to the fungi by photosynthesis while the latter supplies nutrients and offers protection to the algal component. </em>
There are different types of lichen based on the growth structure:
Fruticose lichens grow upright and shrubby and posses either round or flat branches.
Foliose lichen appears like a leaf with upper and lower layers. They are usually flat or convoluted in nature.
Crustose lichens are small in appearance with flat, crusty growth on surfaces on which they grow.
Answer:
B. physical anonymity.
Explanation:
Anonymity can be explained in psychological research as a situation whereby the data collected from participants is confidential and cannot be traced to any particular individual.
Deindividuation is known to be a phenomenon in which people engage in seemingly impulsive and sometimes violent acts in situations in which they believe they cannot be personally identified.
In this case, people that are not physically present tend to be more hostile or engaged in some cruel act. This is because they know they can be seen face-to-face, and people will not know that they are the perpetrator of the act.
In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.
- Number of bee keepers over the period
The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.
- Area of trees suitable for the honey bees
The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.
- Pollution
The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.
Answer:
This protein doesn't have a secondary structure (i.e., alpha helices or beta sheets), thereby it interacts with the specific molecule trough its loops
Explanation:
Protein loops may interact with diverse molecules including nucleic acids (RNA and DNA), proteins, signal molecules, etc. These protein sequences (loops) interact with both polar and non-polar head groups
