Society adapts things discovered by science
Answer: Descriptive, Comparative and Experimental (which comes from experimentation).
Explanation:
There are three types of scientific investigations:
- Descriptive: This type of scientific investigation studies parts of a system, which can be natural or artificial. <u>It describes everything that is being studied and no predictions are made</u>. There are three types of descriptive methods: case-study methods (an in-depth study is produced from many sources with different methods), observational methods (no questions asked, just an observation of the behavior of a subject and no manipulation of the variables), and survey method (some people are interviewed and the researchers study the answers.)
- Comparative: <u>It gathers information from organisms, systems, places or from any source, to compare them</u> using also a control group. But, there is no imposed treatment because it is not ethical or because it is not possible. So, the treatment is only observed.
- Experiment: As its names says, <u>it uses an experimental test designed to study some phenomena, where variables are controlled</u> so the treatment is not only observed as the comparative method. Then those variables are measured to collect information or evidence that supports or not a previous hypothesis and is used to assess theoretical knowledge. The independent variable is manipulated while the dependent variable is measured. This type of scientific investigation comes from experimentation.
Answer:
A. Tt - Tall or Short or Both
B. tt
- Short Only
C. TT- Tall Only
Explanation:
Given -
Height of plant is controlled by a single gene.
"T" represents tall heighted plant while "t" represents short heighted plant
Considering "t" is a recessive allele and "T" is a dominant allele.
Thus,
a) Tall Only means that both the alleles in the genotype would be "TT"
b) Short Only means that both the alleles in the genotype would be "tt"
c) Tall or Short or Both means that the genotype has one "T" and another "t" allele, represneted by "Tt"
Thus,
A. Tt - Tall or Short or Both
B. tt
- Short Only
C. TT- Tall Only
Planktonic copepods are important to global ecology and the carbon cycle. They are usually the dominant members of the zooplankton, and are major food organisms for small fish such as the dragonet, banded killifish, Alaska pollock, and other crustaceans such as krill in the ocean and in fresh water.
A river of air called the jet stream runs along the troposphere just near the top. The troposphere starts at ground level and rises 11 km up which is equivalent to 7 miles or 36,000ft.
About 3/4 of the air in our atmosphere is in the troposphere and almost all weather happens here. Most of the clouds are found in the troposphere layer.
The jet stream is found just near the top of the troposphere zooming along at a speed of 400km/hr (250 miles per hour)
