#female reproduction #menstrual cycle 

 Here are some events in the process of Fertilization. The correct sequence to complete the fertilization of the egg is: 1. a single sperm nucleus and a egg nucleus fuse to form a zygote. 2. Many sperm cells travel a path through the outer layer of a egg cell. 3. The eggs plasma membrane is penetrated by a sperm cell. 4. A rapid depolorization of the egg plasma membrane occurs . My answer is 2,3.4.1 but I am not 100% sure if that is even right. Help me please :) Also i have another question to ask: Some steps involved in the Process of Fertilization: 1. Zygote. 2.Morula 3.Oocyte 4.Fertilization 5. Cleavage 6.Blastocyst. The order in wihich the steps numbered above occur in the process of fertilization is. I couldn't find this answer in my textbook its not clearly written nor even online. Please get back with me whenever you can with these questions. This helps me a lot. Thank you and have a great day! Answer

#fertilization 

Which of the following rows identifies structures responsible for maintaining the endometrium before and after implantation?

a. Before Implantation: Corpus Luteum After Implantation: Placenta. B. Before Implantation: Corpus Luteum After Implanation: Trophoblast. C: Before Implantation:Maturing Follicle After Implantion: Trophoblast. D. Before Implantation:Maturing Follicle After Implanation: Placenta. I think the answer is either B or C but I'm not 100% sure. I posted the same question but the order got messed up feel free to delete that :) And thank you for your help with my other question . Have a great day :)

#endometrium #fertilization #before and after implantation 

Which of the following rows identifies the site of fertilization and the area in which a fertilized egg implants, respectively?

a. Site of fertilization: uterus Site of Implantation: Endometrium. B.Site of fertilization:uterus Site of Implantation Placenta. C. Site of fertilization:fallopian tube Site of Implanttion Endometrium. D.Site of fertilization:Fallopian tube Site of Implantation:Placenta. I have my answer as D but i'm not sure if its right or not. I have a few more questions. I thought it is more easier to give them at the same time rather than posting them 1 by 1. :) 

Which of the following statements does NOT correctly describe the events following fertilization?

Select one:
a. Only the inner cell mass cells in a blastocyst are pluripotent.
b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding.
c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican.
d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body. 
The chance of successful fertilization is approximately 18% in every cycle. Why does this statistic seem so low? All of the following statements provide a reason as to why the chance of fertilization is only 18% for every ovarian cycle EXCEPTSelect one:
a. If more than one sperm fertilize an egg, multiple embryos can result. 
b. The vagina is very acidic, killing many sperm cells.
c. Some sperm cells are not very motile, while others are formed without a tail.
d. There are two Fallopian tubes and two ovaries, but only one of them releases an ovum every cycle.
 
 
Human chorionic gonadotropin (hCG) hormone is produced by a fertilized egg in order to maintain elevated levels of estrogen and progesterone. hCG is also used to induce ovulation during IVF procedures and is known to stimulate the production of testosterone in the testes. 
Which of the following hormones has similar functions as hCG?
Select one:
a. Estrogen
b. LH
c. Inhibin
d. FSH
Thank you so much for your help last time. :)

#fertilization #pregnancy 

When doctors discuss prenatal development, they often calculate the due date from the first day of menstruation. In fact, the baby’s gestational age is calculated from the first day of menstruation. At a maternity clinic, an obstetrician mentions that when a woman is 10 weeks pregnant, the baby is referred to as a fetus. Which of the following is the correct calculation of the baby’s age from the moment of fertilization, assuming a 28-day ovarian cycle?Select one:

a. The baby is 8 weeks old. This is when organ formation has completed.
b. The baby is 10 weeks old as stated by the doctor.
c. The baby is 12 weeks old and at the end of the first trimester.
d. The baby is in its second trimester. This is when they are referred to as a fetus. I think the answer is d but i'm not 100% sure.

#pregnancy #fetus 

 #9. Which mechanism prevents an ovum from being fertilized by multiple sperm cells?Select one:

a. Once a sperm penetrates the jelly-like coating of the egg, no other sperm cells can penetrate the coating.
b. When more than a single sperm cell fuses with the plasma membrane, multiple zygotes can form, leading to the conception of twins or triplets.
c. When a sperm fuses with the plasma membrane of the egg, depolarization of the membrane occurs.
d. The egg can only survive in the Fallopian tube for 24 hours as it does not have mitochondria to produce energy.
 
#10.Which of the following scenarios does NOT describe an event that leads to the conception of twins?
Select one:
a. High levels of FSH stimulates maturation of three ovums. 
b. One egg is fertilized by one sperm but divides into two zygotes, resulting in two babies of the same gender.
c. Two eggs are fertilized by two sperm cells, resulting in fraternal twins.
d. Two eggs are fertilized by one sperm cell, resulting in monozygotic twins.
For 9 i think its a and for 10 a as well. Not sure if these are correct or not. This is my first time taking bio 30 online. Thank you so much for getting back with me with my questions, this realy helps me to make sure I am on the right track. :)
