A testable question is a question that can be answered and solved by creating and conducting an experiment. Testable questions are often about changing one item to see what impact it has on another.
Example:
Does changing the height of the ramp affect the speed of the skateboard going down the ramp?
The criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide.
Answer:
The correct answer will be option-annelids
Explanation:
Annelids in the phylum of animals which includes about 22000 extant species. The animals of this group possess segmented body and thus are called ringed worms.
Each segment of the body contains the same organs and are usually found in the aquatic environment in the hydrothermal vents and the tidal zones. Some species are found in the terrestrial environment.
Since the biologist found the animal from the deep ocean with a segmented body and soft skin therefore, the animal belongs to the annelids.
Thus, option-annelids is the correct answer.
1. 50% will have the RR phenotype and 50% will have the Rr phenotype.
2. 25% will be RR, 25% will be rr and 50% will be Rr
3. 100% will be rr
The karyotype of a child born with Down syndrome includes a trisomy in chromosome number 21. The rest of the karyotype remains normal.
<h3>What is a karyotype?</h3>
A karyotype is a representation to indicate the chromosomes of a somatic cell in an individual.
In humans, somatic cells are diploids, thereby karyotypes will be formed by two sets of homo-logous chromosomes.
Down syndrome is caused by the presence of an additional chromosome number 21, and therefore the karyotype will exhibit three (trisomy) 21 chromosomes.
