Answer:
The answer is double helix.
Explanation:
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.

I'm giving Brainilest if you answer this and some points and 5 stars and a Thanks: Describe the positions of high and low pressure and the temperature of the land and water to explain how land breezes form.
Answers
Answer:
A high pressure system works downwards and brings with it good weather, while a low pressure system works upwards and brings bad weather. Due to the Earth’s rotation and friction on its surface, air currents are formed. When these currents move clockwise and out of the center, a space is formed at the center. The land quickly loses its heat whiles the water retains its warmth. That means the air over the water is warmer, less dense, and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

1. Hubble’s discoveryin 1924 astronomer Edwin Hubble used a technique pioneered by Henrietta Leavitt to measure distances to remote objects in the sky.Hubble used spectroscopic red-shift data to measure the speeds these objects were travelling then graphed their distance from Earth against their speed.He discovered that the speed at which astronomical objects move apart is proportional to their distance from each other2. discovery in the 1960s of cosmic microwave background radiationOn May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB)It states that the ancient light that began saturating the universe 380,000 years after its creation.It also supports the big bang theoryThus, Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.

Which of the following is an example of when the Law of Dominance would happen?
A. BB X BB - blue
B. Bb - blue
C. bb - white
D. BB- blue
Answers
Answer:
Bb - blue
Explanation:
Is this show the dominant trait will take over for the recessive traits so the dominant trait will still be blue even though there is a recessive trait of white
The example that demonstrates an example of the law of dominance is Bb - blue.
LAW OF DOMINANCE:
According to Gregor Mendel, the law of dominance states that one allele of a gene can mask the phenotypic expression of another allele of the same gene. For example, in a gene coding for color in a particular organism. The allele for blue color (B) is dominant over the allele for white color (b). This act of dominance will only be showcased in a heterozygous genotype i.e. a combination of both blue and white allele (Bb). The phenotype of this organism will be blue because blue allele is dominant. Therefore, the example that demonstrates an example of the law of dominance is Bb - blue.Learn more at: https://brainly.com/question/2931799?referrer=searchResults

Explanation:
The problem here is to complete the photosynthesis reaction.
During photosynthesis, green plants manufacture their food in the presence of sunlight.
They take inorganic materials from the environment which are the carbon dioxide and water and using sunlight, they produce glucose and oxygen gas.
The reaction expression is given below:
Carbon dioxide + water → Glucose + Oxygen
So;
1 carbon dioxide

A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample
A 20% cytosine, 20% thymine, 20% guanine
B 30% cytosine, 209. thymine, 30% guanine
C 10% cytosine, 30% thymine. 40% guanine
D 30% cytosine, 30% thymine, 20% guanine
Answers
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.
According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
What are Bases?Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.
There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
∴ A = T : G = C.
If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.
This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.
Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
