Animal Gestation and Incubation
The Gestation period of an animal is the length of time from conception to birth. In this category you'll find questions and answers about the gestation period of most animals including embryo development inside the body of the mother (viviparous) and outside the mother (Oviparous) such as animals that lay eggs.
806 Questions
How is their length of gestation determined?
The length of gestation is determined by factors such as the species involved, genetics, and environmental conditions. Biological factors like hormone levels, development of the fetus, and size of the species also play a role in determining the duration of gestation. Ultimately, different species have evolved to have specific gestation periods that are optimal for the healthy development of their offspring.
How long is the gestation period for English setters?
The gestation period for English Setters is typically around 63 days, similar to most other dog breeds. It is important to monitor the pregnant dog closely during this time and provide proper care and nutrition to ensure a healthy pregnancy and delivery.
The gestation period of a zebra is around 12-13 months, depending on the species. This is the period of time between conception and birth, during which the zebra develops inside the mother's womb.
Do packsaddle caterpillars come from eggs?
Yes, packsaddle (or saddleback) caterpillars come from eggs. The dark brown female moth (Acharia stimulea) lays clusters of 30 - 50 light yellow, transparent eggs each of which measure 0.06 - 0.08 inch (1.5 - 2.0 millimeter) in length and 0.04 inch (1 millimeter) in width.
How long does it take to roast a pig?
Most 275 gallon oil drum type of cookers are long enough for a 60-75 lb pig if part of the legs are removed to fit.
7 hours is probably the outside length of time and would likely be a stuffed pig. If the pig is stuffed with fruit, veggies, sausages, poultry, etc. you will need to cook until they are done. If the cavity is open to the heat, the pig will cook from inside and outside but exposing the inside will cook it faster as the heat does not have to penetrate the thick skin and fat layer beneath it.
BEST practice is to use a thermometer and occasionally stick it into the rump to check to see if it hit 140+ When the rump hits that, give it no more than 1 hour. Tend your coal and try not to open it up too often. Remember if it is enclosed, it is an oven and you are letting the heat out.
What are the advantages of reproduction in a stable environment?
Disadvantages Often slower than asexual reproduction, and less reliable. The new organisms are genetically identical to their parents. This means they will look exactly the same as each other. There will be no diversity and species will die out. Examples All animals reproduce sexually (e.g. fly, human, snake, frog. All flowering plants and those that make seeds reproduce sexually. E.g. daffodil, grass, rose, oak tree. Plants that make spores e.g. moss, ferns. Fungi e.g. mould, which make spores. Single cells, which reproduce by binary fission, e.g. Amoeba Budding, e.g. spider plant Runners, e.g. grass, strawberry == ==
What anatomical direction is distal?
Distal refers to 'further from the attachment point'. For example, the ankle is distal to the knee.
How does gestation vary among animals?
Gestation varies widely among animals, with some species like elephants having a gestation period of around 22 months, while others like mice have a gestation period of only 19-21 days. The length of gestation is influenced by factors such as the species' size, metabolic rate, and reproductive strategies.
Why is having only one parent both an advantage and a disadvantage of asexual reproduction?
Advantage:
·Only need one member of species to procreate
Disadvantage:
·Since they are pretty much clones they have the same immunity, diseases that kill one will likely kill them all
Have a nice day :)
How long does a hippopotamus stay pregnant?
A hippopotamus stays pregnant for around 8 months before giving birth to a single calf.
What is the gestation period for a pig and how does it compare to human gestation?
The gestation period for a pig is around 3 months, 3 weeks, and 3 days (approximately 114 days). In comparison, the gestation period for a human is around 9 months (approximately 280 days), making human gestation significantly longer than that of a pig.
The gestation perod for all mammals is?
The gestation periods for mammals differs greatly. In general it appears to be very short in small mammals, (some shrews and mice are only a few days) while increasing in length as the mammal increases in size. Elephants, hippos, bears whales and other large mammals have gestation periods lasting 9 to 18 months.
What is the scientific name for the morning dove?
To cite Birds of Oregon, written by Roger Burrowsand Jeff Gilligan, published by Lone Pine Publishing,in 2003, the scientific name for the morning dove is Zenaida macroura. The name Zenaida honors the princess of Naples who was the wife of Charles Lucien Bonapartean early 18th century zoologist.
Name the mammal that has the shortest gestation period of 8 days?
It is a fallacy that any mammal has a gestation period of 8 days.
Two marsupials share the shortest gestation period. The Virginian opossum and the yapok (an unusual, rare water opossum) have a gestation period period of 12-13 days.
Several sources cite the Eastern quoll of Australia as also having a gestation period of anywhere between 8 and 13 days, but this is incorrect. The Eastern quoll's gestation period is 20-24 days.
What is a gestation period in animals?
It varies from animal to animal, but here are a few:
elephant - 645 days,
beaver - 122 days,
domestic cat -61 days,
domestic dog - 64 days,
kangaroo - 42 days,
horse - 336 days,
mouse - 19 days,
whale - 490 days,
zebra - 365 days
domestic cow - 285 days
domestic pig - 114 days
human - 260 days
What are some of the functions of waxes in organisms?
Waxes can serve many different purposes for different organisms.
In plants waxes help prevent water loss.
Waxes make insects chitin impermeable .It protects leaves from abrasive damage . It makes some birds e.g. ducks water proof .
What is the gestation period of an antelope?
The gestation period of an antelope varies depending on the species, but generally ranges from 6 to 9 months.
The shape of an egg is generally oval with one end larger and rounder than the other. It is smooth, tapered, and symmetrical, designed to protect and enclose the growing embryo inside.
Which animal has the shortest gestation period?
Marsupials in general have short gestation periods since the babies are born into the pouch at a rather underdeveloped state. I think the shortest animal gestation period if I remember correctly is that of the opposum, it's 12-13 days long.
How many times does the bee queen mate?
the queen bee flies on her mating flight for 2-3 days during which time the males chase her and mate with her. estimates are that she mates with 10-25 males during that time. afterwards she goes into the hive and never mates again. the sperm lasts her for 2-3 years and when she runs out the worker bees kill her.
What are the advantages and disadvantages of asexual reproduction?
The disadvantages are that it is hard for a species to vary and/or evolve with asexual reproduction because the offspring really only have one parent. another disadvantage is that most species that asexually reproduce are small organisms (single celled bacteria or protists), although there are some plants that are known to asexually reproduce. some advantages include that you do not need another gender partner to reproduce, as long as you have an energy source, you can reproduce all you want
Some advantages of asexual reproduction are
- Large numbers of offspring are reproduced very quickly from only one
parent when conditions are favourable.
- Large colonies can form that can out - complete other organisms for nutrients and water.
- Large numbers of organisms mean that species may survive when conditions or the number of predators change.
- Energy is not required to find a mate.
Some disadvantages of asexual reproduction are
- Offspring are genetic clones. A negative mutation can make a sexually produced organisms susceptible to disease and can destroy large numbers of offspring.
- Some methods of asexual reproduction produce offspring that are close together and compete for food and space.
- Unfavourable conditions such as extreme temperatures can wipe out entire colonies.
The advantages are that if the plant is good at producing ripe fruit or vegetable quickly or is quick at photosynthesis, you take a cutting from the plant and replant it and when it grows it identical to the original. Or it might be a that it is immune to some types of pesticides and other chemicals.
The disadvantages are that if the plants are all the same species there is no differentiating and therefore they can be wiped out by a disease or a change in the climate.
Where does the blue bird of paradise live?
The blue bird of paradise is native to the rainforests of Papua New Guinea, specifically on the island of New Guinea. They inhabit the rainforest canopy and are known for their vibrant blue and black plumage, as well as elaborate courtship displays.
What day of a pregnancy can you differentiate between a chimpanzee fetus and a human fetus?
Around day 40 of a pregnancy, you can distinguish between a chimpanzee fetus and a human fetus based on their physical characteristics and developmental stages. Chimpanzee fetuses have a shorter gestation period compared to human fetuses.
