Question
Which type of research study would best be used to determine how aggressive children are while playing at a schoolyard during recess?
a. confounding
b. case study
c. introspection
d. naturalistic observation
e. experiment
Answer:
D. Naturalistic observation
Explanation:
Naturalistic research as opposed to analog research is reasearch whereby a subject is observed while subject is in his natural habitat and free of manipulation. This is illustrated in the example above where aggressive children could be observed while in their school playing ground. This would leave the subject oblivious of the observer and therefore subject would be his natural self.
The answer is:
- mitochondria and chloroplasts originated as ingested prokaryotes
- mitochondria and chloroplasts have their own DNA
Prokaryotes are exist in simple form organisms (such as single celled animals) Plants in general are considered to be complex organism. Since mitochondria and Chloroplast have separates DNA this fact could be used as an indicator that at one point in time complex organisms were originated from simple form organisms that undergone the process of evolution.
Darnel’s way of thinking, i.e. “Everyone is always angry at me for doing something!", is a:
“Pessimistic explanatory style”.
<u>Explanation:</u>
Explanatory style is a characteristic of a person which shows how they introspect and explain to themselves how and why certain circumstances keep recurring in their lives.
The thought process of Darnel depicts that he is taking things personally, believing that people get angry at him due to his actions.
This kind of explanatory style, people tend to think that it is their fault that things are happening in a certain way and that it happens all the time, hence it is kind of global in their lives.
Thus showing a pessimistic explanatory style
Answer:
AFFECTED FOR PLANT GROWTH
Studies have shown that higher concentrations of atmospheric carbon dioxide affect crops in two important ways: they boost crop yields by increasing the rate of photosynthesis, which spurs growth, and they reduce the amount of water crops lose through transpiration.
affected for nutrition level
AFFECTED FOR NUTRITION LEVEL
Climate change affects food production and availability, access, quality, utilization, and stability of food systems. In short, it impacts all aspects of the food system. Extreme weather-related disasters are increasing and reduce the yields of major crops. Higher levels of CO2 reduce the nutritional value of crops.
