A student conducted a comparative investigation to test the hypothesis that different areas of New York City have different levels of air pollution. Which is a likely benefit of this comparative investigation?
A It provides her with a large amount of information about air pollution in New York City.
B It provides her with results that are valid for a long time.
C It requires that she observe a limited number of variables.
D It allows her to learn about the causes and effects of air pollution in major cities.
Answer: A. It provides her with a large amount of information about air pollution in New York City.
Explanation:
A comparative investigation is when data is collected in order to make a particular comparison.
With regards to the question, the student conducted a comparative investigation in order to test the hypothesis that different areas of New York City have different levels of air pollution.
The benefit of this study done by the students is that it will provide her with a large amount of information about air pollution in New York City. The area with the highest air pollution, what causes air pollution and other necessary information can be gotten.
Therefore, the option is A.
Which of these characteristics is NOT a property of water? (SC.912.L.18.12) A. Increases density as it solidifies B. Functions as a universal solvent C. Exhibits a highly cohesive behavior D. Moderates changes in temperature
Answer:
Option A.
Increases density as it solidifies
Explanation:
Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.

What composes a photosystem?
The "special chlorophyll" molecules in the reaction center are what the photosystem will use to absorb all of the sun's energy.
What is a photosystem?A core complex and a periphery antenna system referred to as the light-harvesting complex I (LHCI) for PSI and the light-harvesting complex II (LHCII) for PSII, respectively, make up each photosystem.
Light-harvesting structures and reaction hubs make up photosystems. To two unique chlorophyll molecules in the reaction center, pigments in the light-harvesting complex transfer light energy.
Sunlight is captured in the chloroplast by pigment chlorophyll molecules arranged into photosystems.
Therefore, the light-harvesting complex, which consists of pigments, and the reaction center make up the photosystem.

A) It is difficult.
B) It involves levers.
C) It involves a transfer of energy.
D) It is done with a machine.
Answer: C. It involves a transfer of energy.
Using the scientific definition, the statement that is always true of work is it involves a transfer of energy. The correct option is C.
What scientific theories?Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.
There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.
In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.
Thus, the correct option is C) It involves a transfer of energy.

There are only three autosomal trisomic conditions (Patau, Edward, and Down Syndrome) where a fetus will survive to birth. Why do you think this is so?
Answer:
An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21
Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.
