18. Replicate the following four DNA strands using what you know about complementary base pairs.
a. AATACGTCCAGATTTT
c. CCCGCGGAATATACA
b. TTAACCGAGTTCAGA
d. AGGGCTACTTCAGAC
Answer:
a. TTAGCAGGTCTAAA
b. GGGCGCCTTATATGT
c. AATTGGCTCAAGTCT
d. TCCCGATGAAGTCTG
The replication can be TTATGCAGGTCTAAAA, GGGCGCCTTATATGT, AATTGGCTCAAGTCT, and TCCCGATGAAGTCTG respectively.
What is complementary base pairing?Complementary base pairing occurs when guanine always hydrogen bonds to cytosine and adenine always binds to thymine in DNA.
In comparison to the A-T bond, which always shares two hydrogen bonds, the bond between guanine and cytosine shares three hydrogen bonds.
Each strand of the double helix contains all of the information required to reconstruct the other half using the base pairing mechanism.
The strands are said to be complementary because each can be used to make the other.
Complementary base pairing describes how the nitrogenous bases of DNA molecules align with one another. The double-helix structure of DNA is also due to complementary base pairings.
TTATGCAGGTCTAAAA, GGGCGCCTTATATGT, AATTGGCTCAAGTCT, and TCCCGATGAAGTCTG are possible replications.
Thus, these are the complementary base pairing for the given codes.

science questions , may be out of order but please help asap ( about mitosis ) may be out of order so i made two questions
Answer:
8. Prophase
9. Gap 1
10.Metaphase
Explanation:
Basically from what I remember
Prophase: Mitosis begins, nuclear envelope is gone
Metaphase: Chromosomes line up and spindle fibers attatch
Anaphase: Chromosomes are torn apart to separate sides of the cell
Telophase: Separates duplicated genetic material into 2 identical nuclei
Cytokenesis: The cytoplasm itself separates and forms 2 cells.
Gap 1: Cells increase in size as new organelles are formed
Synthesis: DNA is formed
Gap 2: DNA is checked as cell begins to divide
Mitosis: Cell divides
So from the simplified versions of things I remember, I think the answers listed above probably suit each question best.

In general, did the simulated mice align with your predictions from the Punnett squares?.
Research studies are often carried out using mouse. From the study, the simulated mice was said to align with the predictions from the Punnett squares. So the answer is Yes.
The reason why some of the percentages did not exactly match your predicted results because the Mice don't have large litters, so the sample size was not large enough.
If the experiment is to be done again, I can improve upon experimental design by;
Increase the number of mice bred. Examine a different trait within mice. Examine a trait in another species. Test patterns for future generations.A lot of studies is been carried out on the Genetics of the mouse. The early development of inbred lines were studied. The mouse is known to be a good tool to identify the genetic basis of both normal and disease traits.

if you visit the beach on a hot summer day you will probably feel a Sea Breeze coming off the water onto the land. Which of the following causes this sea breeze?
A. The water is warmer than the land during the day.
B. Hurricanes that form in the oceans blow air into the shore.
C. During the day,solar radiation warms the land faster than the water.
D. Earth is tilted toward the Sun, causing air to move inland from the water
If I am correct, the answer is supposed to be C due to on hotter portions of the day, land warms much faster than the water. This causes cooler air to rise from the oceans and the wind currents then push the air towards the land.
Which process can cause chemical overheating
Answer:
Thermal Runaway
EX- Thermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature.
Explanation:
For a more simpler explanation , picture a pot of water and as you increase the volume of fire so does the energy (HEAT) inside . As air bubbles (ENERGY) start to quickly evaporate (BOILING) this actually increases the temperature inside causing Thermal Runaway.
4. Using the Celsius scale, at what temperature does water freeze? At what temperature does water boil?
Answer:

The Diagram shows structures that form the surface of the trachea.
Which level of organisation is the structure labelled S ?
A. Cell
B. Organ
C. Organ system
D. Tissue
Structure S is a simple columnar epithelium, which is a type of tissue.
The diagram shows the structures that form the surface of the trachea. The trachea is a tube that carries air from the lungs. The surface of the trachea is lined with a layer of tissue called the epithelium. The epithelium is made up of cells that line the inside of the trachea.
The structure labelled S is a type of epithelium called a simple columnar epithelium. Simple columnar epithelia are made up of cells that are arranged in a single layer. The cells in a simple columnar epithelium are tall and column-shaped.
The simple columnar epithelium in the trachea helps to protect the trachea from infection. The cells in the epithelium produce a mucus that traps dust and other particles. The mucus is then carried away by the cilia, which are tiny hairs that line the trachea.
The other levels of organization in the diagram are organ, organ system, and cell. The trachea is an organ, which is a collection of tissues that work together to perform a specific function. The respiratory system is an organ system, which is a group of organs that work together to perform a common function. Cells are the basic units of life, and they are the building blocks of tissues, organs, and organ systems.

To read signs, you need to have good ________ . focal vision peripheral vision paracentral vision double vision
To read signs, one needs good peripheral vision. The capacity to see things that are beyond of one's direct line of sight is known as peripheral vision. It is the capacity to perceive things that are beyond of one's direct field of vision.
Because it enables a person to perceive items that are situated at the boundaries of their peripheral vision, this form of vision is crucial for reading signs.
For instance, it's crucial to be able to understand signs that are placed along the side of the road when driving. A person might not be able to see the signs and might miss crucial information without adequate peripheral vision. Aside from peripheral vision, clear focus vision is crucial for reading.

A test cross performed between the individual with unkown genotype and the h0m0zyg0us recessive individual. 9) hh. 10) Hh or HH. 11) HH x hh. 12) 100% Hh. 13) Hh x hh. 14) 50%Hh and 50% hh. 15) -16) in the text.
-----------------------------------
Available data:Single diallelic gene codes for hair in Guinea pigsAllele H is dominant and codes for having hairAllele h is recessive and codes for not having hair
For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.
According to this information, we can say that
Genotype Phenotype
HH Hairy pig
Hh Hairy pig
hh Hairless pig
9) Geneviene does not have hair ⇒ Its genotype is hh
10) Fred has hair ⇒ Its genotype is HH or Hh
Possible crosses
11 and 12)
Cross1: If Fred was genotype HH and bred with Genevieve
Parentals) HH x hh
Gametes) H H h h
Punnett square) H H
h Hh Hh
h Hh Hh
F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.
13 and 14)
Cross2: If Fred was genotype Hh and bred with Genevieve
Parentals) Hh x hh
Gametes) H hh h h
Punnett square) H h
h Hh hh
h Hh hh
F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.
50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.
15)
• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.
• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.
16)
The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.
So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.
