Hello, I am currently undergoing a research investigation into the Jewish application of belief for the medical practice of Xenotransplantation, and I was wondering how the Jewish application of beliefs would impact adherents choice surrounding this medical technology.

Is it permitted for females to slaughter animals in halachic process?

I am a bat anusim with 4 generations maternal genealogy and evidences awaiting to meet with the beit din for review of my case. In searching for a synagogue to learn Torah with, I was suggested by the local orthodox rabbi to drive to Shabbat services to begin experiencing Jewish communal life. When I asked if I could leave after Havdalah, he said I shouldn't stay for it. Can a ben or bat anusim in the process of a giur le'chumra drive to synagogue on Shabbat, or be asked to do one counter-mitzvah as a standard ger would? Can they light nerot, make kiddush, and havdalah? As a bat anusim, should women be treated like a geriah or counted as a Jewess? Thank you.

Does the prohibition against shatnez include only single garments containing wool and linen? Or does it apply to wool and linen worn in separate garments simultaneously? For example, what are the laws pertaining to wearing a linen shirt with wool pants, or a linen hat and woolen socks?

Today my wife mounted a green wreath on our front door. It looks like the attractive wreaths hanging on many front doors in our neighborhood. Fortunately, it does not feature holly berries. I question whether this wreath is permitted. I feel that it is reminiscent of pagan practices. I know we are not supposed to follow the practices of the nations, and I can't help feeling that this wreath has a pagan symbolism that I don't know. I would appreciate learning whether this wreath is permitted, and if not, what the relevant halakhah is. Thank you very much.
