If the interference value is 1, then what is the probability of recombination between genes A and B if: 1.There is a recombination between genes B and C, where the gene order is A-B-C; 2.The recombination fraction between A and B is 0.05; 3.The recombination fraction between B and C is 0.45?
A. 0.45.
B. 0.05.
C. 1.00.
D. 0.15.
E. 0.0.
Answer:
E. 0.0.
Explanation:
The measure of crossing over coincidence interrelatedness between one cross over and another in a given pair of chromosome is known as what is called Interference.
Given that :
the interference value = 1
The probability of recombination between genes A and B is zero i.e 0.0 because:
when another gene co-occur with a particular gene during cross over, the coefficient of coincidence decreases. We know that the interference is maximum at 1, we can say it ranges from 0-1; now that two recombination is taking place in two genes,the probability is likely to decrease from 1 to 0.0
Similarly; Since the probability of recombination is taking place between two genes i.e genes A and B. Then there is no probability of double crossover when interference value = 1 but when it is zero there is probability of double crossover to occur. With that being said, the probability of recombination between genes A and B is 0.0

Why the rainforest in Costa Rica is not rich with plants? Remember to use scientific language
Answer:
Deforestation is the major problem causing lack of rich species in Costa Rica. This is due to over grazing by cattle.This may lead to flooding which affect fertility of the soil.These animals graze on the plants without regulations,and cause erosion as their hoofs percolate the soil, further reducing soil fertility.
In addition to sustain the beef production, trees were fell to for cattle ranching.This ultimately contributed to loss of the forest species.
Banana plantation is an additional factor.Forest were cleared to cultivate banana, which affects forest population.

Suppose that a population composed of 100 individuals existed on an island in the Caribbean Sea. Two different alleles of the A gene were present in this population ( a1 and a2 ) at equal frequency. The following events occurred to this unlucky population. Determine what evolutionary force (mutation, migration, drift, or selection) is represented by each event. In addition, tell the effect of each eventon the genetic composition of the population.A) A devastating fire caused the death of 10 individuals.
B) A disease swept through the island and killed 13 individuals. The a1 confers resistance to the disease.
C) A disease swept through the island killing 13 individuals. Neither a1 nor a2 confers resistance to the disease.
D) A boat containing individuals from a different island containing a1, a2, and a3 alleles landed at the island.
E)The leader (whose genotype is a1a1) declared that only individuals with the a1 have the right to be on the island and mate. All a2, a3 individuals moved to another island.
F) A man stumbles upon a barrel that has spilled its contents on some rocks. Unknown the to man, who cannot read, the barrel says "Radioactive". He decides to bring one of the new glowing rocks home to show his wife and puts it in his pants pocket.Some of their babies had an a4.
Answer:
Explanation:
D) A boat containing individuals from a different island containing a1, a2, and a3 alleles landed at the island.
This is an example of migration. It is the movement of an organisms into a particular place or habitat. It increase the population of its new environment and decrease the population of the environment it migrated from.
E)The leader (whose genotype is a1a1) declared that only individuals with the a1 have the right to be on the island and mate. All a2, a3 individuals moved to another island.
This is example of selection. Selection is done in a large population to select traits with desired characteristics. Selection helps to have individual with the best features.
F) A man stumbles upon a barrel that has spilled its contents on some rocks. Unknown the to man, who cannot read, the barrel says "Radioactive". He decides to bring one of the new glowing rocks home to show his wife and puts it in his pants pocket.Some of their babies had an a4.
This is an example of mutation. It a sudden heritable change in the genome of an organism. it can be caused by exposure to radioactive material. Mutation can have a detrimental effect on individual carrying it or useful.
A) A devastating fire caused the death of 10 individuals
Drift- Genetic drift leads to the loss of genotype that are less frequently perpetuated or less occuring and are selected against.
B) A disease swept through the island and killed 13 individuals. The a1 confers resistance to the disease.
Selection- they have selective advantage of been resistance to disease.

1. The length of a dog's tail is an inherited trait. The allele for short tails is dominant (T) over the
allele for long tails (t). A dog breeder mates two short-tailed dogs (parents). One parent is
homozygous and the other is heterozygous for this trait (10 points).
a. Complete the Punnett square for the genetic cross described above:
Answer/Explanation:
Given==> short tail allele (T) is dominant, and long tail allele (t) is recessive.
Genotype of homozygous short-tailed dog = TT, while genotype of heterozygous short-tailed dog = TT
Required==> Punnett Square showing a genetic cross between both parents: i.e. TT X Tt
*See attached image for the Punnett Square
From the Punnett Square, 50% of the offspring of the First generation would be homozygous short-tailed, while 50% would be heterozygous short-tailed.
All the offspring would be all short-tailed as well.

Name the ionic compound PbCO3
Answer:
lead carbonate
Explanation:
The ionic compound PbCO3 is called lead(II) carbonate.
Let's break down the name to understand it better:
1. The symbol "Pb" represents the element lead.
2. "CO3" is the chemical formula for carbonate, which is a polyatomic ion consisting of one carbon atom and three oxygen atoms.
To name the compound, we use the Stock system for naming compounds containing transition metals like lead.
1. The Roman numeral "(II)" indicates the charge of the lead ion in the compound. In this case, lead has a +2 charge. The Roman numeral helps differentiate between different possible charges of the metal ion.
2. The word "carbonate" represents the polyatomic ion CO3.
Therefore, the name of the ionic compound PbCO3 is lead(II) carbonate.

Explain the relationship between mutations, adaptations,
natural selection, and extinction.
Answer:
Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.

Answer:
the answer is D
Explanation:
The oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is an endergonic reaction, but the flow through this point in glycolysis proceeds smoothly. Part A How is the unfavorable equilibrium constant overcome
Answer:
This inbalance is constantly overcome by the production of excess product (1,3-bisphosphoglycerate) which triggers the reversible reaction through the action of the enzyme called glyceraldehyde 3-phosphate dehydrogenase in the process called gluconeogenesis .
Explanation:
A cofactor (NAD+) and a phosphate molecule are crucial to this reaction to produce NADH which results in ATP a high energy molecule. an OH ion is removed from the glyceraldehyde-3-phosphate molecule and transferred to the NAD to form NADH molecule and an intermediate (thioester). The Phosphate molecule then binds to the thioester to form 1,3-bisphosphoglycerate

It was believed for a long time that Jellyfish were a trophic “dead end” and that no organisms utilized jellyfish as a food source. Based on the illustration above, is it true that Jelly fish are at the top of the food chain? Explain your reasoning using the data.
In the Irish sea, a lot of different types of water animals eat jellyfish. It would be hard to say that they are on the top when all these animals/fish eat the jellyfish. Out of 2500 examples of different species the herring had more than 20 percent of jellyfish in them out of 512 that were cut open to see if a jellyfish was in them. In this whole experiment 2500 sea creatures were gutted and the results definitely weren't in the jellyfishes favor. Although the Grey Gurnard, Dab, Sprat, Poor Cod and Squid do not eat much Jelly Fish. The Herring and Dragonet do. I def finitely do not think they are on the top, but they sure do not have that many sea creatures eating them. And you would of thought that the ones that did would be bigger. I am actually very surprised to see that so many creatures were found with the Jelly Fish inside of them. I also wonder what other creatures eat it that we may not know about yet.
how lysosomes may be involved in the removal of the interdigital membrane of the developing mammalian fetus.
Answer:
Lysosomes are organelles that contain hydrolytic enzymes (lysozymes) which are required for membrane degradation, thereby they may be important during the removal of the interdigital membrane.
Explanation:
Lysosome plays a critical function by digesting cellular components such as, in this case, the interdigital membrane. During mammal embryo development, the interdigital membrane is reabsorbed, it is a structure between the digits that appeared during evolution in aquatic animals. However, in terrestrial mammals, it is a vestigial structure leftover from their ancestors.
