Answer:
B
Explanation:
Jesssica is blood type A and her husband Graham is blood type O. She is worried because they are pregnant and their future child has a rare disorder which will require him to need regular blood transfusions. Jessica worries that if their son ends up with type O blood, like his father, it will be hard to get the necessary regular blood transfusions because people with O blood can only accept O blood. What is the likelihood of their child having blood type O?
Answer:
- 50% probability if Jessica has genotype "iAi"
- 0% probability if Jessica has genotype "iAiA"
Explanation:
Blood group in humans is controlled by multiple alleles namely; iA, iB and i. iA and iB are codominant but both dominant over i. The following blood types and their respective genotypes are possible;
- Type A: iAiA or iAi
- Type B: iBiB or iBi
- Type AB: iAiB
- Type O: ii
According to this question, Jessica is blood type A (iAiA or iAi) and her husband Graham is blood type O (ii).
- If Jessica has a genotype iAi, the probability that they will give birth to a child with blood type O (ii) is 50% (see punnet square)
- If Jessica has a genotype iAiA, the probability that they will give birth to a child with blood type O (ii) is 0% (see punnet square).

which statement best describes a cause and its effect during the process or muscle contraction?
Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

a 30 rock cut cave monuments famous for its murals
Ineeditnow
Answer:
Ajanta Caves
Explanation:
Because stress is a force, it... A) takes energy out of rock B) adds energy to rock C) adds volume to rock. D) makes rock harder.
Answer:
it adds energy to the rock
Explanation:
Because stress is a force, it adds energy to the rock. This stress/force is being applied to the rock. Whether the rock moves or not you are applying a force to the rock and it has potential energy. If the rock moves, you are adding energy to it and creating kinetic energy as the rock moves. Other forces such as gravity and friction can push against your force and prevent the rock from moving. Therefore, there are many forces at play in such a scenario.
What is the period of a wave if the wavelength is 100 m and the speed is 200 m/s?
O 0.5 s
o 25
100 s
200.000 s
Answer: 0.5 s
Explanation: speed = wavelength · frequency and period T = 1/ frequency.
Frequency = speed / wavelength = 200 m/s : 100 m = 2 s^-1 and T = 0.5 s
The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?
186
214
158
200
172
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.
Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
Answer:
The type of mutation that causes this translation error is called deletion. Deletion occurs when a section of a DNA is deleted or lost. In cystic fibrosis, three nucleotides are deleted that results in the lost of phenylalanine
I was thinking B but I need another opinion.
NO LINKS AND IF YOU DO YOU WILL GET REPORTED
Answer:
YES YOU WERE RIGHT B MAKES SENSE
Explanation:
Answer:
B) 1 and 2
Explanation:
Both 1 and 2 are true in the actual Solar System. Number 3 is incorrect because Earth is only tilted at a 23.5 degree angle. Number 4 would make a oval or other shaped orbit, so it's incorrect.

As the lock for the door opens you enter another room. This one has plain cement walls with huge silver and copper pipes running from floor to ceiling. The room reminds you of a basement mechanical room even though you have just gone upstairs. Everywhere there are old wooden crates and piles of gears of all sizes, springs, gages and the hands of old clocks. As you gaze around the door you just entered closes and will not open. (and even if it would you are not sure of what has happened to the Antique Dealer and maybe there is some danger that way.) Someone in the group checks their phone but there'is no signal. Maybe all this cement and metal is blocking your signal. Next to another door is an interesting framed collage made of miscellaneous gears and pieces.
A safe room can be the difference between life and death during a home invasion. While a home security system is extremely important for immediately contacting law enforcement, a safe place for anyone inside to wait for the police is necessary. It can always be a great place to store valuables that you do not regularly use, like having
Compare marshes, swamps, and bogs.
Answer:
Marshes: Have extremely good ability to support grasses, reeds, flowers, and insects due to their high nutrient soil. They usually are around lakes/rivers/and other bodies of water. They are frequently covered in water however not always covered in water.
Swamps: Have extremely good ability to support wood like plants, trees. They are also permanently covered/submerged in water all year around.
Bogs: Basically they are a gravesite of a dead plant life. When a lake fails to support itself it turns into a bog, its plant life dies off and will start rising to the top creating almost a film. However even though the plant life dies the insects, reptiles, and Amphibians thrive.

A reliable DNA analysis is based on the DNA conditions. The importance of using undigested cells is that DNA is well-preserved, not affected by external factors, and can be used to compare it to database sequences.
------------------------------------------
Dr. Pringle studies niche partitioning and competition reduction among coexistent species in Africa.
He is interested in knowing the exact source of food of different herbivorous species. To do so, he is using the technique of DNA metabarcoding.
He collects fresh animals' dung and gets the indigested plant cells.
DNA is isolated, sequenced, and compared with the DNI of known species, which are a potential source of food for these animals.
Once he matches the cells' DNA with the corresponding plant species from the database, he can use this information to detail the animal's source of food.
The importance of getting fresh, undigested cells from the dung, is that
The animal's digestive enzymes have not broken the cell walls and digested the cell content. The dung environmental conditions such as pH, temperature, or microbiota have not affected the cell's DNA. Undigested cells' DNA is well-preserved and can be used to compare it with the plant species database.------------------------------------------------------
