Assume for the purposes of this problem that the order of and distances between three linked genes are the following: unc-32 10mu vab-7 20mu dpy-17 What is the probability of obtaining a phenotypic unc-32 vab-7 offspring from a cross between a heterozygous fly(unc-32 vab-7 dpy-17/ ) and the triple recessive nematode
From the distances between genes and their order, it is possible to get recombination frequencies per region (simple and double recombination frequencies). The probability of obtaining a unc-32 vab-7 + offspring is 0.09 = 9%.
---------------------
We are usually asked to get the order of genes in a chromosome. To do so, we need to get the distances between genes. And to get distances between genes, we need to get their recombination frequency.
When three genes are involved, we get the distances by taking the recombination frequency, P, per region.
We talk about regions, R, when we are making reference to the space between two genes.
Gene 1 -----(R1)----- Gene 2 --------(R2)------ Gene 3
P1 P2
P1 = recombination frequency between Gene 1 and Gene 2P2 = recombination frequency between Gene 2 and Gene 3⇒ P1 = (SR + DR) / N
⇒ P2 = (SR + DR)/ N
Where:
SR is the number of simple recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals.The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).
In the exposed problem, we need to do the inverse way. We already have the order and distances between genes, and we need to get the recombination frequency, P.
We know that the order of genes is as follows,
unc-32 ------------- vab-7----------------- dpy-17
Distances are:
Region 1 = 10 MURegion 2 = 20 MUWe need to get the probability of obtaining a phenotypic unc-32 vab-7 + offspring from a cross between a heter0zyg0us fly (unc-32 vab-7 dpy-17/ + + + ) and the triple recessive nematode (unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17).
Cross:
unc-32 vab-7 dpy-17 / + + + x unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17
To get the genotype unc-32 vab-7 + , a simple recombination, SR, must occur in region 2.
So we need to get the simple recombination frequency in Region 2.
To do so, first we need to clear the following equation
Distance between vab-7 dpy-17 = P2 x 100 = 20 MU
20MU = P2 x 100
P2 = 20 / 100
P2 = 0.2
The recombination frequency in region 2 (P2) is 0.2.
Now, we need to get the simple recombination frequency in this region.
P2 = (SR + DR) / N
P2 = Simple recombinants Frequency + Double recombinants Frequency
R1 = 10 MUR2 = 20 MUDouble recombinants Frequency = 10% x 20% = 0.1 x 0.2 = 0.02P2 = Simple recombinants Frequency + Double recombinants Frequency
0.2 = Simple recombinants Frequency + 0.02
Clearing the equation,
Simple recombinants Frequency = 0.2 - 0.02 = 0.18
Simple recombinant frequency in region 2 will produce the following two chromosomes,
unc-32 vab-7 ++ + dpy-17So half of this frequency will produce one chromosome, and the other half will produce the other chromosome.
unc-32 vab-7 + ⇒ 0.09+ + dpy-17 ⇒ 0.09So, the probability of obtaining a phenotypic unc-32 vab-7 + offspring is 0.09 = 9%.

In water cycle, liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
What are the characteristics of water cycle?The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds.
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water evaporates and becomes water vapor.

Explanation:
According to WikiDiff "snake and salamander, are that a snake is a legless reptile of the sub-order serpents with a long, thin body and a fork-shaped tongue while salamander is a long, slender, chiefly terrestrial amphibian of the order caudata, resembling a lizard or a newt." moreover "Salamanders are a type of amphibian; they have moist skin and are usually found in damp habitats near or in water. Salamanders are closer related to frogs despite how different frogs and salamanders look. Lizards are a type of reptile; they have dry skin with scales and are purely terrestrial (burkemuseum, 2021).

describe evidence from biogeography that species evolve adaptations to their environment
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

How does energy store in an ATP molecule?An adenine base is joined to a ribose sugar, which is joined to three phosphate groups, to form the nucleotide ATP. Two phosphoanhydride bonds, which have high energy, connect these three phosphate groups.
At the cellular level, energy is used and stored as adenosine triphosphate (ATP). Adenine, ribose sugar, and three serially bound phosphate groups make up the structure of ATP, which is a nucleoside triphosphate.
Therefore, the structure of ATP is a nucleoside triphosphate having Two phosphoanhydride bonds, hence c and d store energy within the molecule.

Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.

What evidence do the positions of the peaks and dips in its spectrum provide about an object? A. expansion B. elemental composition C. motion D. temperature
Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.
The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.
These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.
When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that less light is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, the peaks tell you what kinds of bonds are present from which we can identify the elemental composition.
