Good job ❤

Haha short and sweet. I LOVED that you explained dominant vs recessive genes in terms of the functional vs non-functional enzymes they encode. This was never clear to me in my high school biology classes and it didn't seem obvious to my professors either "what makes a gene dominant or recessive?". Of course, other mechanisms could be involved but I'm glad you indeed kept it short and simple. Thanks!

Hello ma'am, Thank you for this great video and being so kind to the students by explaining everything so beautifully. QUERY- At 5.45, you said that water enters the root through diffusion. This has confused me as in the texts we follow, it says that water enters the root through osmosis. Request you to please clear this doubt. Thank you.

it is a shame this isn't what comes up first when looking for A Level B biology stuff because this channel is so underrated compared to other bio a level channels, especially for visual learners, the fact you draw everything out instead of using static images really really helps, thank you so much.

You are a great teacher 🫶🏼🫶🏼

u are a life saver

educative and informative love it ❤

Omg I can’t tell how much this helped! Thank you!!

amazing video, thank you ! I have a question though, how can abscisic acid can open and close the stomata ? like its the same chemical but has 2 different effects. do we simply choose which one would occur based on the information given ? (Ex if hot and dry climate then say it closes etc)

This deserves more likes and views, thank you so much.

Best explanation EVER!

thank you so much this was explained really well

thank youuuuu

What does km stand for

I'm so grateful for this video, I just wished I'd have found your channel before - my exam is tomorrow 😅

Is this the complete chapter I feel like 2 videos are two less

You are a life saver 💗

thank u soooooooooooo much for the explanation it was soooooooooo good!!!!!!!!

Super helpful, thank you for this! Did you have a cold while recording this? Didnt sound to well, but hope you are all right!

Thank you soooo much ❤❤❤❤

Thank you!

can i use the equation in serial as well? as i find that easier

Hey!! The volume of the serial dilution ten fold changed from 10 cm cubed to 9 cm cubed in each test tube, correct?

thank you!

4:30 second main lead syndrome :(

love your videos but please try to increase the volume

I learned a lot from this, thank you!!

literally saving me

thank you so much

she ateeee

Awesome explanation. Hats off to You. Madam

Here's how Gregor Mendel's laws of independent assortment and segregation connect to meiosis: **Meiosis:** Meiosis is a type of cell division that shuffles and reduces the genetic material (chromosomes) of a diploid cell (2n) to create four haploid (n) gametes (sperm or egg cells). This process is crucial for sexual reproduction, ensuring genetic diversity in the offspring. **Mendel's Laws:** * **Law of Segregation:** This law states that during gamete formation, the alleles (different versions) of a gene for a single trait separate from each other. Each gamete receives only one allele for each gene. **Connection to Meiosis:** During meiosis I, homologous chromosomes (chromosomes that code for the same trait) pair up. However, these pairs then undergo **independent assortment** during meiosis I. This means that the homologous pairs separate **randomly** from each other, with one chromosome from each pair going to each daughter cell. This random separation is the key to segregation. * **Law of Independent Assortment:** This law states that the inheritance of traits coded for by different genes is independent of each other. The alleles for one trait separate from each other independently of the alleles for another trait. **Connection to Meiosis:** Since homologous chromosome pairs separate **independently** during meiosis I, the alleles for different genes located on **non-homologous chromosomes** are also **separated independently**. This allows for various combinations of alleles for different traits to end up in the gametes. **Example:** Imagine a pea plant with genes for flower color (purple or white) and pod shape (round or wrinkled). These genes are located on different chromosomes. * **Segregation:** During meiosis, the alleles for flower color (P or p) on the homologous chromosome pair separate, with one allele going to each daughter cell. The same happens for the alleles for pod shape (S or s) on another chromosome pair. * **Independent Assortment:** Since these genes are on different chromosomes, their separation is independent. This means a gamete could receive a P allele for flower color along with an S allele for pod shape, or a p allele with an s allele. All possible combinations (PS, Ps, pS, ps) can occur in the gametes due to independent assortment of chromosomes. **Combined Effect:** These laws working together in meiosis create a vast pool of genetic variation in the gametes. When fertilization occurs (sperm and egg fuse), the resulting zygote receives a unique combination of alleles from both parents, leading to genetic diversity in the offspring. **In summary, Mendel's laws of segregation and independent assortment are based on the random separation of chromosomes and alleles during meiosis. This shuffling of genetic material creates the foundation for genetic variation in sexually reproducing organisms.**

I had a question tht is, does the Na+ ions jump nodes to the nodes of ranvier? Bcz of that fact that impulses travel by jumping from node to node if I m correct hence is it that? I m really confused abt it for which my question might sound confusing as well, but I hope u understand what I mean

Thank you so much

how do you get like 10 cm^3 of each successive solution when doing a serial dilution. like when diluting by a factor of 10 and have each successive beaker with a volume of 10cm^ as what stays in it

Ur amazing ❤️❤️❤️

watch this in 1.25x trust me 👍🏻👍🏻

Please upload genetic variation videos if you can

Thanks

fuck yea

thankss this vid really helped

In 6:58 why is it 10 e.g.u not 100? Is one egu per one big division?

thanks!

the volume of your sound is too low

thank u sm :)

KZfaq teaches us more effectively than in class

Thank youu for making these!! they are sooo helpful!!!!

Productions ideas goodnight

Incredible explanation
