Answer:
phycological method
Explanation:
The development of a hypothesis is the step in the scientific method that comes before the three steps.
What is a scientific hypothesis?A scientific hypothesis is an idea that provides a tentative form of explanation for one single phenomenon or a set of phenomena that is observed in the natural world.
Falsifiability and testability are the two primary features of a scientific hypothesis. These are reflected in an “If" or a "then” statement which summarizes the idea presented in such a way that it can be accepted or rejected through experimentation.
The process of the formation and testing of a scientific hypothesis is an important part of the scientific method. The scientific method is the approach used by scientists use when they are attempting to understand and test ideas in the form of a hypothesis that they have observed about natural phenomena.
Therefore, the development of a hypothesis in the scientific method comes before experimentation.

When red light strikes certain cones, they excitea particular bipolar cell. When green light strikes the same cones, they inhibitthe bipolar cell. This observation supports which theory
Answer:
The correct answer is : The opponent process theory
Explanation:
The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.
The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.
For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.
Thus, the correct answer is : The opponent process theory

The ______ family of macromolecules are composed of carbon, hydrogen and oxygen in a 1:2:1 ratio and includes sugars, starches, glycogen, and cellulose
Answer:
The correct answer is - carbohydrates.
Explanation:
Carbohydrates are one of the major macromolecules other than protein, lipids, and nucleic acid. Carbohydrates are the macromolecules made up of carbon, hydrogen, and oxygen in the ration of 1:2:1 which means one carbon, two hydrogens, and one oxygen.
These are divided into monosaccharides, disaccharides, and polysaccharides. These are commonly known as sugars, these molecules include, glucogen, cellulose, and starches.

You discover a unicellular organism that moves by what appear to be pseudopodia. You conclude that this organism is ______.
Answer:
either a type of amoeba or a type of slime mold
Explanation:
Based on the description provided you would most likely conclude that this organism is either a type of amoeba or a type of slime mold. That is because these are the most common types of unicellular organisms that move by temporarily protruding an arm-like projection of a eukaryotic cell membrane in order to travel in the direction that it is protruding that member from its cell membrane. This form of movement can be seen in the picture below.

DNA consists of two strands with complementary pairs of nucleotides. Match each strand of DNA with its complement. Tiles
CATGGAT CGGTACA CGGTTAA TAAGGCC ATTGCGT
The matching of each strand of DNA with its complement is as follows:
CATGGAT: GTACCTA.CGGTACA: GCCATGT.CGGTTAA: GCCAATT.TAAGGCC: ATTCCGG.ATTGCGT: TAACGCA.What is DNA complementarity?
DNA complementarity may be defined as the process through which demonstrates the resemblance of DNA bases in the double helix such that adenine in one strand is opposite thymine in the other strand and cytosine in one strand is opposite guanine in the other.
The mechanism of DNA complementarity also explains the principle of Chargaff's rule. It states that the amount of adenine equals to the amount of thymine while the amount of cytosine equals to the amount of guanine.
According to Watson and Crick, DNA consists of two strands with complementary pairs of nucleotides. One strand is a template to the synthesizing strand which forms complementarily with respect to the template or parental strand.
Therefore, the matching of each strand of DNA with its complement is well described above.

2. The mammalian support system is an ______
with an _______ branches
Answer: osteocytes, nerves
Explanation:
The mammalian support system includes many of the osteocytes which are trapped within the bone matrix. The osteocytes maintain a connection through tiny channels also called canaliculi. Through these channels, the nerves pass through in the form of branches supplying water, and nutrients to the bone. This entire system is supportive of mammalian structure.
