You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when you cross them you make F1 plants that are Cyan in color (a light aqua color). The ratio of offspring is as follows: There were 42 plants with Blue flowers (R1), 39 plants with Green flowers (R2) and 86 plants with Cyan flowers. Is the number of your progeny consistent with a single-gene incomplete dominance inheritance pattern

Answers

Answer:

Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.

Given:

R1R1 = 42

R2R2 = 39

R1R2 = 86

Total R1 alleles = 2*42+86 = 170

Total R2 alleles = 2*39+86 = 164

Total alleles = 334

Frequency of allele R1 = 170/334 = 0.51

Frequency of allele R2 = 164 / 334 = 0.49

Expected number of each phenotype:

Total population = 167

Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44

Green = R2R2 = 0.49 * 0.49 * 167 = 40.10

Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46

Phenotype     Observed(O)    Expected (E)    O-E      (O-E)2     (O-E)2/E

Blue                 42                   43.44               -1.44       2.0736     0.0477

cyan                86                   83.46                 2.54     6.4516     0.0773

green              39                    40.1                    -1.1       1.2100      0.0302

Total              167                     167                                               0.1552

Chi-square value = 0.155

Degrees of freedom = no. of phenotypes – 1

Df = 3-1 = 2

Critical value = 5.99

Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

what are the interactions between atoms that are hydrolyzed by fungi to release nitrogen from these molecules?

Answers

A small amount of nitrogen is fixed by lightning, but most of the nitrogen harvested from the atmosphere is removed by nitrogen-fixing bacteria and cyanobacteria (formerly called blue-green algae). The nitrogen cycle transforms diatomic nitrogen gas into ammonium, nitrate, and nitrite compounds.

During mammalian embryogenesis, the first differentiation event that occurs leads to a polarization of the outer cells of the 16-cell morula. This outer layer of cells forms the trophectoderm and the inner, apolar clump of cells become the inner cell mass. The inner cell mass will give rise to:

Answers

Answer:

the entire embryo

Explanation:

The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.

g Neuron A and neuron B interact with neuron C. Neuron A will produce an IPSP of -2mV in neuron C; neuron B produce an EPSP of 3mV in neuron C. The resting membrane potential is -70mV and the threshold is -50mV. Neuron A fires 6 times rapidly at the same time that neuron B fires 4 times rapidly. What is the resulting membrane potential in neuron C

Answers

Answer:

-70 mV

Explanation:

Given that Neuron A and Neuron B interact with Neuron C

Neuron A produces ; - 2mV of IPSP  and fires 6 times

Neuron B produces ; 3mV of EPSP and fires 4 times

Resting potential = - 70mV

threshold = - 50mV

The resulting membrane potential in neuron C

= -70 + 6(-2) + 4(3)

= -70 - 12 + 12  = -70 mV

According to the diagram how are the three components
of a nucleotide important to the structure of DNA?

Answers

Answer:

A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.

What is Climate Change?


Explain your answer.

Answers

What is Climate Change?

Climate change is a change in the usual weather found in a place.

How it helps us:

Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.

How it works:

As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.

How it affects us:

Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

Which statement correctly describes a feature of the rock cycle?
O Rocks are preserved through the process.
O Rocks change from one type to another.
O Different rock groups are not related to one another.
O Rocks change from one type to another in a specific order.

Answers

Answer:

The correct description of a feature of the rock cycle is:

O Rocks change from one type to another.

Explanation:

Sedimentary, metamorphic, and igneous rocks are the three main rock types.  Together, they form the universal rock cycle.  A sedimentary rock, for example, can change from its known state to another state by passing through crystallization, metamorphism, erosion, and sedimentation.  There are no specific orders for the change.  The processes that they pass through determine the resulting type.

Answer:

Rocks change from one type to another.
