Answer:

The response is 32 sister chromatids

Explanation:

During interphase, DNA replicates to produce two copies (i.e., 16 chromosomes) that are further distributed among the two daughter cells. Moreover, each chromosome has 2 sister chromatids attached by the centromeres. In consequence: 16 x 2 = 32

How does the introduction of invasive species such as the brown tree snake upset the stability of the legal system
Assoli18 [71]

Answer:

Invasive species compete for the same natural resources such as food and water which the native species also need for survival.

Explanation:

Invasive species upset the stability of the ecosystem because the prey in their new environment does not have the needed defense against them. They also upset the food chain, consume so much, and overpopulate in the new territory thus causing the extinction of the native species.

The introduction of brown tree snakes in Guam disrupted the ecological system as their population increased rapidly because their preys in this new environment lacked the ability to defend themselves against the brown tree snakes. For this reason, more than twelve native birds in the Guam Islands went into extinction. They also consumed the natural resources needed for the survival of the native species.

The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.

How do they use bias to sell their products? How would you use skepticism to evaluate the data that these companies use in their
Fittoniya [83]
 They use cognitive biases like framing, loss aversion, status quo etc. to elicit an emotional response in hopes of you making impulsive purchases.

You can use skepticism by listening more carefully to what is being said and looking up any claims made by the advertiser. Like if they say they are the cheapest car insurance, you don't just believe them you compare prices.

Anit [1.1K]

Answer: DNA ligase.

Explanation:

Polymerase chain reaction is a technique used in molecular biology by scientists to make several copies of a DNA sample which enable them to take a smaller portions of it and expand it for more detailed study.

PCR mixture is premixed and contain thermostable DNA polymerase, oligonucleotides primer, four deoxynucleodide triphosphates, Magnesium chlorides, a propietary buffer.
