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?
Answers
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

Read God's rules of health and sanitation for Israel in
Lev. 11:1-8 and Deut. 23:12-14. How might these
rules have protected His people from diseases such as
those caused by parasitic worms? Relate your answer
to the mode of transmission of many parasitic worms.
Answers
Answer:
It is transmitted in the body through contaminated food.
Explanation:
These rules of God's about health and sanitation have protected Israeli people from diseases which was caused by parasitic worms because these parasitic worms entered the body by not washing hands and contaminated food. These parasitic worms are present on the skin as well as in the food so the person can save itself from these parasitic worms if he or she wash hands properly before eating the meal and eat clean, fresh and healthy food.

Which best describes how to classify water?
A It is an element because it is made
from a pure substance.
В
It is a compound because it is made
of a single kind of molecule.
© It is a mixture because it is composed
of more than one molecule.
D It is a solution because it is a
homogenous mixture of different
compounds.
Answers
Answer:
D
Explanation:
Water is a compound and scientifically known as H[tex]_{2}[/tex]0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...
Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.Ngl this was tricky, but I hope this helps :)
which statement best describes a cause and its effect during the process or muscle contraction?
Answers
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.

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?
Answers
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).
Provide two reasons why it is important to isolate undigested plant cells.

Answers
Answer:
It helps to support growth and helps producing energy to do vital functions.
Hope this helps!
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.------------------------------------------------------

186
214
158
200
172
Answers
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.
