Mangrove trees can provide safety and shelter to many juvenile fish and small creatures. They also help filter out pollution.
Transcription is when DNA segments are copied into RNA.
1. RNA Polymerase bonds to a promoter (Those cool start/stop codons)
2. RNA Polymerase breaks all the hydrogen bonds between the two stands of DNA
3. RNA Polymerase create the pair strand for one of the DNA strands (Uracil instead of Thymine!)
4. Hydrogen bonds break between the DNA strand and RNA strand
5. DNA is zipped back up and RNA either floats around in the Nucleus (if there is one) or exists through a pore
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.

An amoeba is considered a "single celled animal". It does not classify as a specialized cell.
