The inversion would suppress recombination.
In Drosophila, the mutations which are recessive are lethal or recessive sterile. Balancer chromosomes are used to hold the deleterious mutations in stable shares as well as to save you recombination with the aid of suppressing.
Chromosomal inversions prevent the recuperation of recombinant chromosomes in ways.
- the crossovers do now not shape within the location of inversion breakpoints, due to the fact synapsis is inhibited.
- unmarried crossovers' inner inversions result in aneuploid gametes that cannot give upward push to normal progeny.
Drosophila is a genus of flies, belonging to the own family Drosophilidae, whose participants are often referred to as "small fruit flies" or (much less regularly) pomace flies, vinegar flies, or wine flies, a connection with the feature of many species to linger around overripe or rotting fruit.

Answer:
Transporters are the integral membrane proteins that serve to move the substances across the membrane.
Explanation:
Transporters are the membrane proteins that serve to move specific ions or molecules across the lipid bilayer. These are the integral membrane proteins. Transporters include carriers, channels, pumps, etc. Channels are the integral membrane proteins that serve to provide a pathway for transport of charged and/or polar substances that otherwise can not cross the non-polar core of the lipid bilayer.
Pumps are involved in the active transport of substances against the concentration gradient and use the energy of ATP hydrolysis. Some of the examples of transporters are voltage-gated ion channels, GLUT1 glucose transporter, F₀F₁ ATPase proton pump, etc.
Answer:
Independent variable
Explanation:
In a scientific experiment, an independent variable is that variable which the experimenter changes or manipulates in order to effect an outcome. Only one independent variable should be tested at a time in a good experiment, all other variables should be kept constant. The initial independent variable in this experiment is TYPE OF SUBSTANCE put in the students' eyes.
However, according to the question, the researcher did not keep track of what they did in that free time. Hence, many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The location of every student should be a CONSTANT VARIABLE i.e. same for all students but now it has become an INDEPENDENT VARIABLE because it has been changed.
Answer:
There are 7 obligate categories included in hierarchical classification The highest rank is the kingdom, followed by division, class, order, family, genus and species.
