Is it possible to be 10 weeks pregnant with no yolk sac and no embryo?
No, by this stage the fetus should be clearly visible. The yolk sac is visible from 5 weeks.
What is difference between animal pole and vegetal pole?
The part of egg which has more concentration of yolk is the vegetal pole and the part with less concentration of yolk is called the animal pole.
What are the nutrients contain in egg?
Egg white and yolk.
Are Branston mayonaises vegan?

How do fish eat when they are not born yet?
Fish develop from eggs that contain a yolk. The yolk (like the yolk of a chicken egg) provides the fish embryo with all the food energy it needs to grow until it hatches.
How does the amount of yolk affect blastulation?
The amount of yolk present in an egg can affect blastulation by influencing the cleavage pattern and rate of cell division. Eggs with more yolk tend to have slower and asynchronous cleavage, which can impact the formation of the blastula. Higher yolk content may also affect the size and nutrition available to the developing embryo during blastulation.
Who has more yolk frog eggs or sea star egg?
Sea star eggs have more yolk compared to frog eggs. Sea star eggs are considered macrolecithal, meaning they contain a large amount of yolk which is necessary for the development of the embryos. Frog eggs, on the other hand, are typically microlecithal and contain less yolk.
How does the vegetal pole differ from the animal pole of a zygote?
The vegetal pole of a zygote contains more yolk-rich cytoplasm compared to the animal pole, which has less yolk and more nutrient-rich cytoplasm. This difference in yolk distribution influences cell division and differentiation during early development.
Could blighted ovum be mistaken for prenancy to earl y to see?
Yes, it definitely can be mistaken for a viable pregnancy. An ultrasound can usually help in determining whether it is a blighted ovum or a pregnancy. If the sac is >8mm without a visible yolk sac (transvaginal ultrasound) or >16mm without a visible embryo (also transvaginally), it is considered a blighted ovum. Transabdominally, it is a blighted ovum if it measures >20mm without a visible yolk sac or >25mm without a visible embryo.
What group of vertebrate embryos contain a moderate amount of yolk because their larvae can obtain their own food?
Amphibians
Does a chicken grow from the white or the yolk of an egg?
The germinal disc is located on the yolk, so that is where the initial cellular division takes place. But a chick can not develop with out both the yolk and the whites (albumen). The yolk is a high concentration of fats which provides energy for growth where as the albumen is high in proteins also needed for tissue growth.
