Explanation:
This explanation is the opposite of true testing - a term known as falsifiability. Falsifiability, when it relates to science, refers to how it should be possible to prove a hypothesis or theory wrong. Thus, the point of testing for falsifiability is to test in which condition is the theory wrong.
A term that might relate to the phrase ‘true testing’ used in the question would be testability. Which refers to the practice of testing a hypothesis or theory to see whether it is true or false.
True testing has been the scientific method that uses various steps to conclude the findings. "True testing means that a serious effort is made to create experiments that support your hypothesis." Thus, option B is correct.
What is True testing?True testing has been defined as the assessment scientific method that is involved in solving the question and issue by formulating the hypothesis and then researching the possible observations and solution that concludes and proves the findings.
It falsifies or proves the hypotheses right or wrong based on the experimental design setup. It does not falsify each possible explanation, nor is always fully correct. It also is not conducted to support the manufacturing and support it financially.
Therefore, option B. True testing experiments to sustain the hypothesis.

A red-colored female New Hampshire Red chicken mated with a red-colored male New Hampshire Red chicken and produced golden-colored offspring. Which statement best explains how the offspring could inherit a trait not shown in the phenotypes of either parent?
Answer:
See the answer below
Explanation:
The statement that could best explain how the offspring could inherit a trait not shown in the phenotypes of either parent would be that both parents are heterozygous for the red color.
Heterozygous parents can produce offspring with a phenotype that is distinctly different from that of either parent if the recessive alleles come together during random fusion of gametes.
Let us assume that the red color (R) in the New Hampshire chicken is the dominant one and the recessive one is the golden color (r). The genotype of the heterozygous parents would be Rr.
Rr x Rr
RR Rr Rr rr
There is a probability (1/4) of producing a golden color chicken (rr), a trait that is not displayed in either of the parents.
Examination reveals that 180.2 g/mol of glucose contains 72.1 grams of carbon, 96 g/mol of oxygen and the remainder is hydrogen. How many g of hydrogen are there in 55.5 g of glucose?
Mass of Hydrogen = 3.7 g
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
180.2 g/mol of glucose-C₆H₁₂O₆ contains 72.1 grams of carbon, 96 g/mol of oxygen and the remainder is hydrogen
Remainder Hydrogen :
[tex]\tt 180-(72.1+96)=11.9~g/mol[/tex]
% mass of Hidrogen in Gllucose :
[tex]\tt \dfrac{11.9}{180}\times 100\%=6.61\%[/tex]
So mass of Hydrogen in 55.5 g Glucose :

Write one paragraph!!!!!reasons why the minimum wage should be increased.
Answer:
There are pros and cons, I will explain mostly pros. After all the pros outweigh the cons.
Explanation:
Increasing the minimum wage can be letting people work less or earn more. This can have a major impact on the economy in America. It can reduce poverty within some families households. A con concerning this though is that people who work for low pay can lose their jobs and their family can become poor. It can also affect the federal minimum wage.
Hopefully this helped you out a lot. Please make sure to make my answer brainliest. Have a great rest of your day or night
Answer:
Minimum wage increases allow people to work less and earn more. This may have a significant influence on the American economy. It can help some families get out of poverty. People who labor for little compensation risk losing their employment and being unable to provide for their families, which is a drawback. As a result, the federal minimum wage may also be affected.

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.

How many moles of carbon are there in 5 g of carbon?
Answer:
0.416666667
Explanation:
number of moles= mass of sample ÷ molar mass
=5÷12
=0.41666667
The number of moles of carbon are there in 5 gram of carbon is 0.41 moles.
How do we calculate moles from mass?Moles of any substance will be calculated by using the mass by following the below equation:
n = W/M, where
W = given mass of carbon = 5g
M = molar mass of carbon = 12g/mol
On putting values, we get
n = 5 / 12 = 0.41 moles
Hence required moles of carbon is 0.41 moles.

True or False: If you find the percent by mass of all of the elements in a compound, it will always add up to exactly 100.00%
Answer: true
Explanation: because Mass percentage composition is found by calculating a fraction of the total mass by each element present in a compound. The whole compound itself would equal one or 100% in all the elements that make it up would only be a fraction, so it will always have to add up to 100%

how to name iupac compounds
Answer:
In order to name organic compounds you must first memorize a few basic names. These names are listed within the discussion of naming alkanes. In general, the base part of the name reflects the number of carbons in what you have assigned to be the parent chain. The suffix of the name reflects the type(s) of functional group(s) present on (or within) the parent chain. Other groups which are attached to the parent chain are called substituents.

How do magnetic stripes show the history of Earth's magnetic field?
A. As you move away from an ocean ridge, the rocks get older.
B. As you move away from a coast, the rocks get younger.
C. As you move down through the seafloor, rocks get older.
D. As you move eastward along a continent, rocks get older.
The way that magnetic stripes show the history of the Earth's magnetic field is A. As you move away from an ocean ridge, the rocks get older.
What do magnetic strips show of Earth's history ?By looking at how our planet's magnetic field changes throughout time, scientists may estimate the age of the seafloor. A geomagnetic reversal is the periodic reversal of the currents in the liquid core that generate the Earth's magnetic field. Throughout Earth's history, this has occurred frequently.
When researchers examined the seafloor's magnetic characteristics, they found normal and reversed magnetic stripes of varying widths. These magnetic patterns are symmetrical on both sides and parallel to the mid-ocean ridges.
Away from midocean ridges, they observed that the age of the bottom became progressively older.

Answer:
The molecule has a bent geometry
Explanation:
Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.
Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.
The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.
What must occur in order for matter to change states?
A.
A chemical change must occur.
В.
The temperature must change.
C. Heat must be added or removed.
D.
Other substances must be added.
Answer:
C. Heat must be added or removed
Explanation:
When matter changes states it is due to the overall loss or gain of heat. In addition, heat being added or removed is what will cause a temperature change, but a simple temperature change is not enough to change states. For example, a temperature could go from 50 degrees to 51. This will not cause a change in states. So heat must be added or removed in order for matter to change states.
