In Drosophila, the genes for eye color, wing shape, and wing length are located on chromosome II. Purple eyes (pr), arc bent wings (a), and vestigial wings (vg) are the mutant forms of the wild type traits red eyes, straight wings, and long wings, respectively. You've discovered some data in your genetics laboratory which indicates that the distance between vg and pr is 12.5 m.u., the distance between a and pr is 44.7 m.u., and the distance between a and vg is 32.2 m.u. what is the chance of a double crossover between these three genes
Answer:
The expected double recombinant frequency = 0.0402 = 4.02%
Explanation:
Available data:
genes for eye color, wing shape, and wing length are located on the same chromosomePurple eyes (pr) is the mutant form of the wild type traits red eyes (pr+)Arc bent wings (a) is the mutant form of the straight wings (a+)Vestigial wings (vg) are the mutant forms of the long wings (vg+)the distance between vg and pr is 12.5 m.uthe distance between a and pr is 44.7 m.uthe distance between a and vg is 32.2 m.u→ Two genes that are very close will have a few recombination events and are strongly bounded.
→ The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
1) First, we need to know their order in the chromosome, and to do so, we need to compare the distances between them.
The most distant pair is a-pr
----a---------------------------------------------pr---
║-------------------44,7 MU-------------║
From gene a to vg there are 32.2 MU
----a-----------------------------vg--------------pr---
║-------------------44,7 MU-------------║
║----------32.2 MU------║
Finally, de distance from vg to pr is 12.5 MU
----a-----------------------------vg--------------pr---
║-------------------44,7 MU---------------║
║----------32.2 MU------║--12.5 MU--║
We can name region I to the distance between a-vg, and region II to the distance between vg-pr.
2) To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cM. And that the maximum recombination frequency is always 50%.
1 MU -----------1% of recombination
32.2 MU -----X = 32.2 % of recombination
12.5 MU-------X = 12.5 % of recombination
3) The expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.
The expected d. recombinant frequency = 32.2% x 12.5% = 0.322 x 0.125
The expected double recombinant frequency = 0.0402 = 4.02%

What is the function of ATP in living things? 1
Explanation:
The function of ATP IN living organisms is that ATP is stored in all the cells for energy of all cells.
ATP captures the chemical energy by digesting food particles, breaking it down to deliver into the
cell process enough to disperse ATP throughout the bloodstream for energy to every cell of the body, to work properly in digestion, releases it to fuel all cells in the body, this is the last process for fuel in the cell system in the digestive process..

Environmental scientists calculating pollutant half-lives often define a transport rate constant that is analogous to a reaction rate constant and describes how a pollutant moves out of an ecosystem. In a study of the gasoline additive MTBE in Donner Lake, California, scientists from the University of California, Davis, found that in the summer the half-life of MTBE in the lake was 26.01 days. Assume that the transport process is first order. What was the transport rate constant of MTBE out of Donner Lake during the study
Answer:
k ≈ [tex]2.7 *10^{-2} d^{-1}[/tex]
Explanation:
For a first order reaction
Half life ( [tex]t_{1/2}[/tex] ) = 0.693 / k
k = rate constant
[tex]t_{1/2}[/tex] = 26.01
hence k = 0.693 / ( 26.01)
k ≈ 2.7 * 10^-2 d^-1
This is a detailed simple solution as required

~AH1807Which of the labeled structures is an adaptation that is primarily responsible for helping a paramecium control its water balance?
Paramecium diagram
A. Structure A
B. Structure B
C. Structure C
D. Structure D
Structure D , The term "contractile vacuole" refers to this structure. The vacuole gathers extra water from the cytoplasm and contracts to release it. As a result, paramecium doesn't swell and explode in hypotonic liquids.
Why are contractile vacuoles necessary for organisms?Specialized contractile vacuoles control the amount of water in cells. Its spherical form allows it to gather extra cell fluid and empty it outside. It is essential for preserving the osmotic pressure inside the cell. Protists are eukaryotes with only one cell and are found in wet and aqueous habitats.
The name "contractile vacuole" refers to what?As its name implies, the contractile vacuole expels water from the cell by contracting. The contractile vacuole periodically expands (collecting water) and contracts (releasing water). Several seconds are required for one cycle, depending on the species .

One hummingbird is born with a short, stout beak as a result of a genetic mutation, the humming bird will not live as long as the others.
What is mutation ?Mutations are defined as the change in the nucleotide sequence of genetic material due to different process such as substitution, deletion or insertion of the nucleotides leading to changed or faulty protein.
The type of mutations leads to the early and delayed termination of the transcription of a gene, mutation of a single nucleotide leads to termination of transcription otherwise called as nonsense mutation.
If a mutation shows no effect on the protein, known as the silent mutation.
It won't be able to gain sufficient resources/ necter like the others hence it will most likely have poor body condition and will not live as long.

Compare and contrast prokaryotes, eukaryotes, and viruses. Be as detailed as possible. Include 2 examples of each type of cell and 2 examples of viruses.
1 or 2 pg
please
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Answer:
Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the basis of their cellular characteristics. For example, prokaryotic cells lack a nucleus and other membrane‐bound structures known as organelles, while eukaryotic cells have both a nucleus and organelles. Prokaryotic and eukaryotic cells are similar in several ways. Both types of cells are enclosed by cell membranes (plasma membranes), and both use DNA for their genetic information.
Prokaryotes include several kinds of microorganisms, such as bacteria and cyanobacteria. Eukaryotes include such microorganisms as fungi, protozoa, and simple algae. Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells). Viruses - Corona virus, HIV.
