It can trap in oxygen and other gases
The correct answer is D. Abduction
Explanation:
In medicine, the movement of limbs or bones is classified into different types including abduction, adduction, extension, and circumduction. In this way, adduction occurs when the bone or limb moves towards the middle line of the body or center of it while abduction occurs if the movement makes the bone or limb be away from the center of the body. On the other hand, extension occurs when a movement makes the angle of body parts wider and circumduction occurs when the movement is circular. Considering this, the type of movement in which a bone moves away from the midline of the body is the abduction.
The correct option is BY CONDUCTING EXPERIMENTS THAT EXPOSE THEIR PROPERTIES.
Scientific investigations are always ongoing in all parts of the world, scientists strive to build on existing knowledge by carrying out more experiments that are targeted at obtaining more information above that which is already known.

In the spermatheca, females of many insect species, including honeybee queens, can store gametes secreted by their sex partners.
<h3>What is Spermatheca ?</h3>
The female insect's spermatheca is an ectodermal structure that receives, stores, and releases sperm for egg fertilization. According to the species, spermathecae differ in size and shape.
- They often come from the median oviduct, which is located close or on the genital chamber. A secretory duct called the ductus seminalis connects the spermathecal sac, also known as the receptaculum seminis, to the genital chamber, where the sperm are released.
- The number of spermathecas varies among taxa, however the majority of insects only have one. Depending on the species of insect, the spermatheca has different morphologies. The spermatheca is composed of the spermathecal gland, duct, and reservoir. Both of these fluids feed the sperm. Both the spermathecal glands and the male accessory glands secrete substances that feed the sperm.
So lastly we can say that, t females of many insect species, including honeybee queens, can store gametes shed by their mating partners in - the spermatheca.
