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.
What is responsible for the blue sky?
Answer:
The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.
Explanation:
Answer:
sun shine
Explanation:
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time
difference between fluids and nonfluids
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
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.

Carbon dating is a process where scientists evaluate the percentage of Carbon-14 atoms that have decayed to
Carbon-12. The process of changing
from Carbon-14 to Carbon-12 involves the atoms losing two neutrons.
What type of reaction occurs when Carbon-14 changes to Carbon-12?
O Single Replacement
O Fusion
O Decomposision
O Fission
Answer: flood
Explanation:
The type of reaction that occurs when Carbon-14 changes to Carbon-12 is fission reaction. The correct option is D.
What is nuclear fission?Nuclear fission is the operation by which an atom's nucleus splits into two or several smaller nuclei.
Even by radioactive decay's energetic standards, the fission process frequently produces gamma photons and releases a large amount of energy.
Nuclear energy can be used to generate electricity, but it must be liberated from the atom first. Atoms are split to release energy during the nuclear fission process.
The decay of carbon-14 is another nuclear reaction that we can use. Carbon is a necessary element for living organisms that constantly exchange carbon, the majority of which is carbon-12.
However, some of those carbon atoms are carbon-14 isotopes.
Thus, the correct option is D.

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.

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.

In a laboratory demonstration, a balloon filled with methane and oxygen was exposed to a flame. The result was a brief, large flame. The students were asked to formulate an equation for the reaction. One answer is below. (3 points) Is this equation correct? Explain your reasoning.
Answer:
CH4(g) + 2O2(g) -------> CO2(g) + 2H2O(g)
Explanation:
Even though the question is incomplete because the equations are missing. However, one thing that is clear from the question is that the reaction is a combustion reaction.
A combustion reaction is a type of reaction that produces heat and light. The mixture of methane and oxygen yielded a brief, large flame which shows that combustion has taken place according to the equation shown above.

3. What is found around the roots of some plants that turns nitrogen from the form we cannot use to the form we can use?
Answer:
Bacteria
Explanation:
Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.
Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.
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.
