Embryology

The gestation period for a cat is typically around 63-65 days. During this time, the embryo develops into a fully-formed kitten inside the mother's womb. At birth, the kitten is ready to survive and navigate the world outside the womb.

Embryo size depends upon size of animal .

An amniote is any of a variety of types of vertebrate which have an amnion - the sac in which an embryo is suspended - this includes mammals, birds, and reptiles.

There really isn't much difference between a zygote, embryo, and fetus. A zygote forms after fertilization and becomes an embryo, which later becomes a fetus.

I dont freaking know

Yes it is. The Ovum combines with one Spermatozoa to first form a Zygote; this develops into the multi-Celled Blastocyte which quickly develops into an Embryo.

This may be wrong, but I believe that it comes with the embryo it's self and provides nutrients.

The tissue that provides food and oxygen for an embryo is called the placenta. It is a temporary organ that forms during pregnancy and connects the developing fetus to the uterine wall to exchange nutrients, oxygen, and waste products between the mother and the developing baby.

At 16 weeks, a human embryo is about 4.6 inches (11.6 centimeters) long. It is about the size of an avocado and is starting to develop more defined features like facial expressions and fingernails.

• During cleavage G1 and G2 stages are by-passed so cells simply progress from S (DNA synthesis) to M (mitosis) without the intervening growth phase
• As a result cleavage cells continue to decrease in sizeuntil they approximate the size of normal somatic cells

When you have an embryo with two similar parts, this means that there will be identical twins. They are formed when a single egg are split into two. Identical twins will always be the same sex.

The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta

An egg contributes the majority of the genetic material needed for the embryo to develop, including the mitochondria for energy production. In contrast, a sperm cell provides only half of the genetic material necessary for embryo formation.

the phylogenetic relationships between species of different phyla

During development, the blastula undergoes a process called gastrulation, in which the cells rearrange and differentiate into the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to all the tissues and organs in the embryo. This process is essential for the formation of a complex, multicellular organism from a simple, single-celled embryo.

it goes on drugs and steriods and takes up smoking

Yolk or blood are food for embryo .

4 extremely visible

this website stinks it has no answers to my questions

Your question is wrong as there are various types of hernia . Males have inguinal hernia which can't occur in females .On the other hand females have femoral hernia not present in males .

At 4 weeks of development, the embryo is significantly larger than the original zygote. The zygote is a single cell formed from the fusion of sperm and egg, while by 4 weeks, the embryo has undergone multiple rounds of cell division, resulting in a structure that is now several millimeters in length and beginning to develop distinct features. This growth marks a critical stage in the transition from a single cell to a multi-cellular organism.

The precise color of an embryo will change as it develops, but for much of development, pigmented cells have not yet formed, so the embryo will mostly be white-pink in color. The embryo proper will be white or off-white, but the circulatory system forms pretty early so the red of the blood moving through the embryo gives it a pinkish hue.
