Answer:

<u>Part A</u> : 70 secondary oocytes will be formed.

<u>Part B</u> : 70 first polar bodies will be formed.

<u>Part C</u> : 70 ootids will be formed.

Explanation:

During oogenesis growth maturation of a single oogonium produces one primary oogonium.

the primary oogonium then undergoes meiosis -1 and produces  one secondary oocyte and first polar body.

The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.

The ootid then differentiates into the ovum.

As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.

As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.

As women age, many experience an increased sense of urgency to void, as well as an increased risk of incontinence. this is usual
ad-work [718]

As women age, many experiences an increased sense of urgency to void, as well as an increased risk of incontinence. This is usually the result of age-related changes in the bladder.

Incontinence is the inability to regulate urination, which can range from a minor leak of pee after laughing, sneezing, or coughing to a full lack of bladder control. Numerous conditions, such as urinary tract infections, vaginal infections or irritations, or constipation, can cause incontinence. Some drugs have the potential to induce momentary bladder control issues. Weak pelvic floor muscles or a weak bladder may be to blame for incontinence that lasts longer.

The bladder wall may stiffen with age and lose some of its capacity to store pee. You lose some of your ability to hold it. Additionally, you might need to urinate more frequently and be more likely to get urinary tract infections. Bladder control concerns, such as leakage or urinary incontinence (inability to contain pee), or urinary retention are among the kidney and bladder issues that are more likely to develop as we age (not being able to completely empty your bladder) infections of the bladder and other urinary tracts (UTIs)

Does the size of a bouncy ball affect the bounce hight
Inessa [10]
I'm pretty sure it does. Because if the ball was small, it bounces more higher than a ball that is big. It has much more mass and density.

What happens to RNA polymerase II after it has completed transcription of a gene? a. It begins transcribing the next gene on the
Over [174]

The correct answer is: b. It is free to bind to another promoter and begin transcription

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter  

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA  

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex.

RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
