Answer:
lungs and kidneys
Explanation:
The median plane divides the body into two halves through a mid line.
The transverse plain is also known as the axial plane and it divided the body into the upper part and a lower part.
The frontal plane is also known as the coronal plane. It divided the body into the dorsal and ventral sections. The dorsal and ventral sections are the front and back sections ( belly and back).
Lungs and kidneys are the only parts which cannot be seen through all the three plains.

Answer:
few predatory lacewings exist in the trees now because they were killed by the spray.
Explanation:
The spray that farmers used, as noted, also killed the populations of a predatory lacewing.
Due to this, few predatory lacewing remained that could not fully deal with the scale population.
This in turn led to the multiplication of scale now that their predators had been done away with.
Answer:
The recombination frequency between two genes can not be more than 50 percent due to the independent and random assorting of the genes that are linked generating 50% recombination.
* Genes should be located far enough from one another so that crossover points can be made.
Example: Genes present at the 2 extreme ends of the chromosome.
* There should not be the linkage between the two genes due to linked genes go together. So no recombination happens.
It may be more than 50% if selected parents are heterozygous. But Mendel took homozygous parents. So, the maximum is 50%. There will be no recombinant if the two genes are linked.
I’m guessing friction of the wheels and the floor help stop it, or the friction of the brake and the wheels cause the wheel to stop moving thus stopping the bike
Brake applied->brake stops wheels from turning->wheels and the floor cause friction and stop the bike
I’m probably wrong but trying to help
