what does the author mean when she describes easter island as ""a destination with solitude built into its dna""?

Answers

A destiny with loneliness built into its DNA why, the DNA of the peoples of Easter Island is unique, there is a theory that suggests that long before Europeans discovered the island (in 1722), it served as a meeting place for the Polynesian people and Native Americans. Thus, the Rapa Nui would have in their DNA a mixture of these peoples. That theory was driven by an article published in 2014 that showed that today's Rapa Nui have 8% Native American DNA in their genome.

The why of solitary DNA

The Rapanui, who populated Easter Island,

Had no contact with the Native Americans until the arrival of the Europeans. Or if they did, it left no trace in their genes. That's what a study that analyzed ancient DNA of the island's inhabitants claims.

These results call into question previous research that claims that there was contact and that it may have occurred several centuries earlier.

This is the first time Rapa Nui's ancestral DNA has been sequenced. It's the result? None of the five samples showed DNA from Native American ancestors.

What is right so far? It doesn't seem like much... the mysteries of Easter Island continue...

In this way, the author wanted to say that the DNA of the peoples of Easter Island is unique.

What is the equation for a photosynthesis???????????????​

Answers

[tex]\large\huge\green{\sf{Answer:-}}[/tex]

6CO2 + 6H2O → C6H12O6 + 6O2.

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

Photosynthesis

Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.

Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.

During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

If a cell that is about to divide has 22 chromosomes how many chromatids does it have? How many centromeres does it have?

Answers

44 chromatids 2 centromeres

44 chromatids 2 centromeres, If a cell that is about to divide has 22 chromosomes.

What are chromosomes?

In the synthesis phase, the number of chromatids doubles while the number of chromosomes remains constant. Although the number of chromatids is unaffected, anaphase doubles the number of chromosomes.

Depending on whether or not the DNA has replicated and when the sister chromatids split, the chromosome changes during the cell cycle.

Meiosis I and Meiosis II are the two division cycles that occur during a meiotic cell division. Since the genetic material duplicates during the S phase of meiosis I, there will be 2n chromosomes during metaphase I.

Therefore, if a cell that is about to divide has 22 chromosomes it have 44 chromatids and 2 centromeres.

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.

Answers

Answer: the answer is A

Explanation:

Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.

On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

Answers

Answer:

Enzyme inhibitor

Explanation:

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.

define the following terms:dispersion and refraction ​

Answers

Explanation:

Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Refraction is responsible for dispersion in rainbows and many other situations. The angle of refraction depends on the index of refraction, as we saw in The Law of Refraction.
