Answers
Answer:
100% correct if you use the answers below :)
Explanation:
1. AGC TTT CG
2. CCA TAA CT
3. deletion
4. Chromosomes contain DNA
5. epigenetic change
A frameshift mutation involves the insertion or deletion of nucleotides in a DNA sequence, which modifies its open reading frame. A deletion is a mutation that involves the elimination of one nucleotide in DNA sequence.
With regard to the questions above described:
1. The sequence AGC TTT CG suffered a deletion of the Adenine (A) base at the second codon (i.e., AGC TTA TCG).2. The sequence CCA TAG CT exhibits a deletion of the Cytosine (C) base at the first codon (i.e., CCC ATA GCT).3. Cystic fibrosis is a recessive inherited disorder caused by a three-nucleotide (codon) deletion in the CF transmembrane conductance regulator (CFTR) gene. This deletion is associated with the loss of phenylalanine (Phe) amino acid in the exon 10 of the CFTR gene.4. The statement 'chromosomes contain DNA' is TRUE. Chromosomes are thread-like structures that contain part or all of the genetic material (DNA) of an organism.5. Epigenetic changes are modifications that affect an organism’s phenotype while leaving its DNA sequence. Epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation).In conclusion, frameshift mutations involve the modification of the Open Reading Frame. Deletion involves the elimination of a nucleotide in DNA. Chromosomes are thread-like structures that contain genetic material. Epigenetic modifications don't modify the genetic (nucleotide) sequence.

7. If you have a 100-base pair DNA molecule that contains 45 cytosines, how
many adenines are there?
Answers
Answer:
5 adenines
Explanation:
Cytosine pairs with Guanine, and Adenine pairs with Thymine. This means, that if there are 45 cytosines, there must be 45 guanines. So that's 90 base pairs down. That means that there are 10 left between adenine and thymine- so that means there are 5 adenines

If a cubical cell with 2-cm sides doubles the dimensions of its sides, what relative change occurs to the ratio of its surface area to volume ratio?
Answers
Answer:
When the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.
Explanation:
Surface area of a cube is given by the formula below:
Surface area of a cube = 6a²
Volume of a cube is also given by the formula below:
Volume of a cube = a³
Where a is the length of a side of the cube.
For the first cube, a = 2 cm
Surface area of the first cube = 6 * (2 cm)² = 24 cm²
Volume of the first cube = (2 cm)³ = 8 cm³
When the side length of the cube doubles, a = 4 cm
Surface area of the second cube = 6 * (4 cm)² = 96 cm²
Volume of the first cube = (4 cm)³ = 64 cm³
The ratio of the area and volume of the new cube is given below:
Area = 96 cm² / 24 cm² = 4
Volume = 64 cm³ / 8 cm³ = 8
Therefore, when the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.

O Type O

Answers
Answer:

Pat's has type A blood & his mom has type O blood, the blood type of his dad must be the type AB blood. One of the parent must possess at least of copy of the A allele.
For Pat having A type blood to have a mom with type O blood, it means, his genotype for the type A blood is heterozygous IAO. His mom's genotype is OO.
Therefore for a couple with the mom as OO to produce a child with AO, there are two scenarios; the father has to possess either AB or AA
If the father is AA and the mom is OO, their offspring could be all AO from the cross between the two.

Explanation:

Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.
What is Coastline?There are approximately 312,000 kilometers of coasts on the continents of the world (193,000 miles). They have changed positions during geologic time as a result of significant alterations in the relative levels of land and sea.
All coastal regions were impacted by sea level dips brought on by the loss of water from the oceans during glacial advances, according to studies of glaciations during the Pleistocene Era.
The sea level during the last Pleistocene glacial epoch is considered to have been nearly 122 m lower than it is now, exposing a significant chunk of what is now the continental shelf.
Therefore, Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

Which type of mixture is it, if the solid settles out of the mixture over time?
O suspension
o homogenous

solution
Answers
Answer:
Suspension
Explanation:
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water).
If the solids settle out of the mixture over time, such a type of mixture is called suspension.
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing.
What are the different types of mixtures?
there are mainly two types of mixtures that are:
homogeneous mixture
homogeneous mixture
A homogeneous mixture is a mixture throughout the solution in which the composition is uniform throughout the mixture.
A homogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
Hence, a suspension is a heterogeneous mixture in which some of the particles settle out over time.

Discuss the possible outcome of an epiphyseal fracture in a 14 year old patient compared to a 40 year old one
Answers
Answer:
It could close growth plate in a 14 year old leading to shorter limbs or crooked limbs
Explanation:
Compared to a 40 year old patient, an epiphyseal fracture on a person of 14 years can be a cause for great concern.
The epiphyses are found at the ending of long bones. New bones are produced from here.
A person of 14 years is an adolescent and still at the puberty stage compared to a 40 year old. Such a person is not yet mature. An injury such as a fracture can cause the growth plate to close thereby disrupting the growth of the bone. A fracture through growth plate can cause shorter limbs.
The possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.
What do you mean by Epiphyseal fracture?An Epiphyseal fracture may be defined as a combination of a horizontal fracture line through the physis and a vertical fracture line that runs from the growth plate through the epiphysis to the articular surface.
The 14-year-old patient is under adolescence so their bone is not completely formed, while a 40-year-old patient almost completed the adulthood stage, so their bone is completely formed and strengthened, which may reduce the chances of bone adjoining.
Therefore, the possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.
