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.

A. is the correct answer. Qualitative observation deals with data that can be observed with our senses.
Answer:
Burning trash.
Explanation:
When we burn trash, it creates small particles of ashes. This small particle of ashes become mix up with the air. Air can blow these particles to the river or any other water resources, which contaminate the water and make a negative impact.
Raising livestock also has some negative impact on contaminated water and makes a negative impact, but burning trash makes the more negative effect more.
Answer:
The correct answer is option A. demonstrates that the E. coli cultures were viable.
Explanation:
In this lab experiment or culture, Plate I and plate III demonstrate, that E.coli bacteria can grow both in the presence and absence of plasmid DNA if ampicillin is not there.
So, which means that plasmid DNA is not required for the growth of E.coli in absence of ampicillin. The presence of growth in wild type (plate 1) and a plasmid containing bacteria (plate 3) in media without ampicillin shows that bacteria are viable in nature.
