Miss Estruch I found your channel through a quick KZread search for a specific topic I will definitely be sharing with my friends also I’m a year 12 student and recently we’ve started year 13 content for aqa starting with photosynthesis so maybe some more year 13 based content would be good as I’m a little worried about learning the new content by myself I know year 13 content is a little on the heavy side 😬 especially because we don’t have the textbooks either to have something to refer to when trying to learn. thank you for asking x

Hello, I few people have mentioned they are now on Photosynthesis so I will pump this higher up the priority list. I do have a photosynthesis required practical and respiration, when you get onto that bit. I will try my best to get some thing on LDR and LIR up within the fortnight
Omg your videos are SUPER helpful, especially the online resources and the exam questions. Thank you soo much.

hello Which minute in the video is that mentioned in?
hi miss thanks for the video, i just wanted to ask if you could please clarify the species definition in many textbooks, where it says "a species is a group of organisms that can interbreed and produce fertile offspring" - doesn't interbreeding mean organisms from different species breeding together and doesn't that then produce infertile offspring? it doesn't make any sense

i thought inbreed was the correct term to use for breeding within the same species
@MissEstruchBiology
3 жыл бұрын
Hello, inbreed is breeding within the same family. Interbreeding is between the difference races of species. I know what you are saying, I don't like the use of 'interbreed' as that often means between different species. I phrase it as 'when individuals breed to create fertile offspring' instead.
