The developing embryo feeds on what besides the yolk in order to grow?
The embryo is the yolk and feeds what would be the white of the egg if cooked.
When does a goose reach sexual maturity?
It's different with every goose, but as an overall generalization, it seems that the geese I come into contact with tend to reach sexual maturity around the age of 4 (18 in goose years, its legal)
What structure do chicken embryos have around them that human embryos do not?
Chickens have an actual shell. The shell along with the embryo is called an egg. Human embryos are inside a females' womb which is made of skin, not keratin like egg shells are.
tail bud, wing bud, nasal pit, allantois, and vitelline vein.
In 72 hours the tail bud and allantois vitelline vein, wing bud, also the nasal pit appears, all the things that are not present in the 48 hour chick.
Why does the sea star embryo have no need of the yolk associated with the chicken embryo?
Lancelets and amphibians have less yolk because they have swimming larvae which can obtain their own food. Reptiles and birds are terrestrial species with eggshells to prevent desiccation, so they are unable to obtain their own food.
What if i am 5 weeks pregnant and no embryo sac?
From what I understand it can take 6 weeks before a sac is detectable on a vaginal ultrasound. If there is no sac at 6-7 weeks there is reason for concern.
"Yes! Fish eggs are jelly-like in texture. There are two different ways fish moms give birth. Some will lay their eggs in a safe, hidden environment where the eggs can grow safely in a nest. Others will keep the fertilized eggs in their bellies, until they hatch inside them and give birth."
How does a chick embryo get nutrients to survive?
The main nutrients that a chick needs to hatch, is the yolk. They do need some air, and some moisture. These things can pass through the egg shell. Egg shells have many small holes that things like this can pass through. If the eggs are kepet at the right temperature, they will hatch.
A fish embryo feeds from the yolk in the egg. Once they are hatched, they still have a supply of yolk in a sac to last them for a few days.
What happens after embryo transfer?
Hopefully it implants to the uterine lining and grows into a fetus
Is there an embryo in every egg?
No. Many, in fact most eggs are not fertilized and are therefore not viable.
How is the embryo of the bird kept in its place?
Strong protein strands called chalaza are attached to both sides of the yolk. Chalaza holds the yolk centered within the albumen (egg white).
What protects a chicken embryo?
When you crack open an egg you will see the yellow part called the yolk. The yolk is surrounded by the clear white substance called albumen. As the embryo develops within the shell, it is protected by the albumen.
In general, the more embryos produced by a mating, the lower the individual survival chances of each embryo due to competition for resources. However, producing more embryos can increase the likelihood that at least some survive to reproductive age, thus potentially increasing overall reproductive success. It ultimately depends on the species and its specific reproductive strategies.
How do you determine if a palomino is a hybrid or a purebred trait?
Palomino is a color and not a breed produced by the introduction of the Creme gene
on an otherwise chestnut horse.
A palomino is eeCrcr and has to be heterozygous at the creme dilution locus.
A homozygous creme horse that is otherwise chestnut at the extension site is
eeCrCr which produces the double dilute color of cremello, a horse that is nearly
white with blue eyes.
Is the presence of large number of chromosomes in an organism a hindrance to sexual reproduction?
No. Sexual reproduction process does not depend upon the number of chromosomes in an organism. Chromosome numbers usually are expressed in sets. 2 sets of chromosomes are present in body cells of organisms. For example, human bears 23 pairs which means 46 numbers of chromosomes. The cells with 2 sets of chromosomes are called diploid cells (2n) and haploid cells contain only one set (n) of chromosomes. Gamete cells are always haploid which are obtained by meiosis cell division of diploid cells. In sexual reproduction fusion of two haploid gametes (male and female) results in formation of zygote which id diploid.So, the number of chromosomes present ina cell whether it is small (cat - 38 chromosomes) or large (butterfly- 380 chromosomes) does not affect sexual reproduction.
How much does it cost to freeze an embryo?
I live in Long Island, NY and my doctor charges $1,200 for the freezing process, no matter how many embryos you have. There's also a maintenance fee, $200 every 6 months. Hope this helps...
How many chromosomes are in a mature erythrocyte?
There is no nucleus or chromosomes in a mature erythrocytes .
What is the first organ to develops the embryo?
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )
