Animal Gestation and Incubation

Kangaroos do not have a longer gestation period, and to do so would be of no advantage anyway. Kangaroos are marsupials, and all marsupials are characterised by having a shorter gestation period than placental mammals of similar size. Most of the kangaroo Joel's development occurs in the mother's pouch, over a period of 8-12 months.

A cow is pregnant, or 'in calf', for approximatly 40 weeks (9 months).

It requires about 8 months.

The length of gestation in a fetal pig can be determined by counting the number of days from the date of fertilization to the date of birth or by estimating based on the developmental stage of the fetus. Ultrasound imaging is commonly used to monitor fetal development and determine gestational age in pigs. Hormone levels and physical changes in the sow can also provide clues to the stage of pregnancy.

The long refractory period refers to the period of time after an action potential during which a cell is unable to generate another action potential. This ensures that cells have enough time to recover before firing again, allowing for proper signaling and coordination in the nervous system.

yes it takes about 2 weeks

Gravida is the Latin pronouncement for a pregnant woman. Gravida 2 means the woman is pregnant for the second time.

Around that, yes. Numbers average between 283 or 285 days, but neither is right or wrong over the other.

This is the length of time that an animal is pregnant for.

How many days in a month varies, so if you started in the beginning of a month that had 31 days till the month ended and the next month was the same, than 63 days would be 2 months and 1 days. But again it depends on how many days are in a month to be able to figure out how many months make up 63 days.

There isn't one. Bodies aren't clockwork perfect, which makes "safe periods" notoriously unreliable, one out of five women using that ends up pregnant within one year.

25 days

yes

Five months (150 days)

63 days

For a tiger, the gestation period averages around 100 days.

For a cow, the gestation period averages around 285 days.

Yes. Here is a picture of what your baby looks like at 34 weeks.http://3dpregnancy.parentsconnect.com/calendar/34-weeks-pregnant.html

A sow's gestation is anywhere from 112 to 115 days, averaging about 114 days.

38-40 weeks it differs. Some go till 42 weeks at that point they usually enduce labor

Closer to 12 months. It tends to be longer than that of a mare who has been bred multiple times.
