The zebra fish mutation that reduced coloration created a null allele of the transport protein gene. Which of the following type

s of mutation would be most likely to create this null allele?A) a neutral mutation B) a silent mutation C) a missense mutation D) a frameshift mutation

Answer:

Correct answer is D.

Explanation:

Silent mutations have no observable effect while neutral mutations does not cause harm or benefit the organism in any way. Missense mutations are single nucleotide changes that only affect one codon and one protein. In this case answer is frameshift mutation because this type of mutation is result of DNA insertion or deletion which changes the way DNA sequence is read and may affect more than one gene.

What are chromosomes? When do chromosomes form?
defon

Answer:

Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Hope this helped! :)

he burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other
Arturiano [62]

Hey there!

A Burrowing owl's habitat is destroyed which is due to human activities and will come under Artificial destruction via human influence and not due to a natural destruction like cyclones, High Richter scale earthquakes, hurricanes with extremely high knot speeds, etc. Instead I'll say because of which the population of the burrowing owl will obviously decrease because they're more adapted to "their previous environment" and most likely "wouldn't adapt to a new unfamiliar environment".

To break these contradictions down simply said "they're unaware of the rules, regulations, type of soil, type of trophic levels, number of predatory organisms, etc. this makes it pretty hard to move from their once said naturally provided nature-made habitat to the burrowing owl, which got lost due to habitat annihilation by human cause. Further making the owls to adapt and change their "NATURAL TRAITS" to make it "CUSTOM" because of which these aren't going to help them instead they'd go either extinct by moving to a newly known unfamiliar habitat rather than their naturally nature gifted habitation.

So Yeah, the correct option [after the question mark ends] to be the least likely outcome would've been  "the population of species of burrowing owl maybe increase as per arriving in a new habitat or introduced to newly made surroundings". This is "Highly and the most unlikely" or the "least likely predictable outcome" for burrowing owls. Introduction of species to newer habitats without any prior training, kills the species and it's progenies.

Hope this helps  you and gives you the detailed analysis for this query for burrowing owls!!!!

Why are raptors a indicator species?
Arturiano [62]
Indicator species may provide useful substitute for large scale surveys to monitor biodiversity. Weconducted surveys in the Afro-alpine habitats of the Bale Mountains National Park (BMNP) with theobjective of identifying indicators for the species richness of the raptor guild. Raptors were countedby scan sampling technique from a suitable vintage point. Three classes of 18 sample units groupedaccording to the variability of the moorland ecosystem in the magnitude of process variables importantfor raptor species richness were used in determining the indicator value of species as a function of their abundance concentration and the percentage of species occurrence per sample group. Thisprocedure determined indicator values for all species in the resident raptor community. Comparisonwith randomly expected values demonstrated that only<span> Aquila verreauxii</span>and<span> A. chrysaetos</span>haveindicator values that were significantly larger than the randomly expected values. The species richnessestimated using the abundances of these two species predicted the observed species richness of thewhole community in a linear regression model that explained 66% of the deviance in the data set.Furthermore, the species richness of the community predicted by process variables had correlation of very high significance with that predicted by the indicator species. We have thus identified twoindicator species to a raptor guild of the BMNP and demonstrated that these two species encapsulatedmost of the information regarding the species richness response of the guild to key process variablesin the Afro-alpine moorland ecosystem. Our findings contribute significantly to current and futureefforts of monitoring the biodiversity of the park providing a cheap and quick means of data generation<span>relevant for making management decisions.                               Hope this helped! :)</span>
