Embryo
The fertilized egg cell is called a zygote and divides to form an embryo.
Humans don't ever really look very pig like during development. There are early periods in development where pig and human embryos look similar but by the time human and pig fetuses have developed to the point of looking even somewhat like their future selves they in no way resemble each other.

No, the chromosomal difference between cattle and humans would prevent a human female from conceiving a fetus with a bovine male.
In direct development there are only a few minor differences between an adult and offspring. No metamorphosis or larvae will occur.

A zygote is a fertilized egg in the womb before it starts to have any recognizable characteristics of a human. Usually a fetus is when the zygote starts to resemble a baby

Think of what steps a human life form must go through between being conceived and being born. Zygote, being the earliest stage of development, and a fetus being the last stage of development before birth. A zygote is the initial cell formed after a sperm and egg have joined. A blastocyst begins at day 5 in mammals after fertilization. This all occurs during the first week of being conceived. After the first week, the developing life form becomes an embryo, and the embryo is the stage where DNA is built.. After week 9 in a human lifeform, it is considered a fetus. This is where vital organs and bone begin to form.
The cell formed by the sperm and the ovum is called a zygote. It is the earliest stage of human development and contains the complete set of genetic information from both parents. The zygote then undergoes cell division to form an embryo, which eventually develops into a fetus.
fetus
same as a human :)
Human fetus
Apoptosis is programmed cell death. It's important to human development because it kills many unnecessary cells in a fetus, such as the ones between fingers and toes.
nothing.
The embryonic period extends to the end of the eight week. After the embryonic period (8weeks), the developing human is called a fetus.
