For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
What are the four ways in which genetic variation is increased in the zygote that eventually is made?
- Fusion of maternal and paternal DNA in the gametes (each gamete contains 23 chromosomes)
- Segregation and independent assortment
- Recombination: crossing over during late prophase
- Random fertilization
What does segregation and independent assortment refer to?
- To the random distribution of the chromosomes from the stem cell and segregation to two daughter cells in meiosis I
- The alleles on different pairs of chromosomes are again distributed independently in meiosis II.
What is the number of different types of gametes that a man can produce?
Where within the seminiferous tubule do the spermatogonia develop into spermatozoa ?
How does the development from spermatogonia into spermatozoa go?
↓
(division by mitosis, 1 goes into:)
primary spermatocytes
↓
(division by meiosis)
secondary spermatocytes
↓
spermatids
↓
spermatozoa
How is the development from spermatids into spermatozoa called?
How is the whole process of sperm cell formation called?
What happens with the spermatozoa, after they have been produced?
How is the acrosomal vesicle formed, and what will it eventually become?
- It will become the acrosomal cap of the mature sperm cell.
What is the role of the sustentacular cells in the spermiogenesis?
- They phagocytose the shed cytoplasm
- They provide nutrients.
What does the mature spermatozoon lack?
- ER
- Golgi apparatus
- Lysosomes
- Peroxisomes
- Inclusions
How does the spermatozoon get nutrients?
What does the acrosomal cap contain?
What does the tail consist of?
What are the 6 major functions of the sustentacular cells?
- Remain blood-testis barrier
- Support mitosis and meiosis
- Support spermiogenesis
- Secrete inhibin
- Secrete androgen-binding protein
- Secrete Müllerian-inhibiting factor
How can the sustentacular cells play a role in maintaining the blood-testis barrier?
What is the role of the hypothalamus in the male reproductive system?
What does LH stimulate?
What do the sustentacular cells do?
- Stimulate synthesis of ABP (androgen-binding protein) and spermatogenesis and spermiogenesis
- Stimulate synthesis of inhibin, which inhibits FSH secretion
What does androgen binding protein (ABP) do?
What type of cells secrete Müllerian-Inhibiting Factor (MIF), and what does MIF do?
- MIF causes regression of the fetal Müllerian ducts.
To what does inadequate MIF production during fetal development lead?
What is functional maturation?
When do spermatozoa become motile?
When do spermatozoa become capable of fertilization?
Which two things are vital for capacitation in the female reproductive tract?
- The Ca concentration has to be regulated
- The membrane cholesterol of the sperm cells has to be lost
What are GPI-anchored proteins and what happens with them?
- They are lost from the membrane of the sperm cell during capacitation.
What cleaves the GPI-anchored proteins from the membranes?
What are the four major functions of the male glands?
2. Providing nutrients spermatozoa need for motility
3. Propelling spermatozoa and fluids along reproductive tract (mainly by peristaltic contractions)
4. Producing buffers: to counteract acidity of urethral and vaginal environments.
What do the seminal vesicles secrete?
What does the prostate gland secrete?
What do the bulbourethral glands secrete?
