The root cap is a small structure but one that serves a very important function for a plant. Protecting the root apical meristem allows for primary growth in the root, which paves the way for lengthening of the plant as well as cell specialization.
The organs forming the male duct system as listed from the male gonad to the body exterior are;
Epididymis = Vas deferens = Urethra
Epididymis is a tube located at the back of the testicles that stores and carries sperm. Vas deferens transports sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. The urethra carries urine from the bladder to outside of the body. Additionally, it has function of ejaculating semen when the man reaches orgasm.
the answer is A. covalent bonds
The mode of evolution that is represented by this example is
called coevolution. Coevolution is the process in which two independent species
influence the evolution of each other. This process involves natural selection.
There is nothing working as a forcing agent. Since this orchid named bumblebee
orchid is totally dependent on a single species named bumblebee for its
pollination and this evolution process, so this process is called coevolution. Various
other organisms also follow this method of pollination to continue their cycle
of evolution.
