Gene combination and their expression in the embryo
It has countless uses in medicine, but is most commonly used by the doctor to "see" a developing fetus in a pregnant woman.
I'm assuming you meant fetus. A fetuses of most of the animal kingdom are identical in the early stages for example there is a time period where someone could not visually identify the differences between a developing human and a developing chicken. As the human fetus progresses it will no longer resemble a developing chicken but will still be similar to other mammals fetuses until the final stages of development. A growing fetus at certain stages will have a tail, webbed fingers, and gills all of which once fully developed are no longer there because we have evolved to no longer have a use for them unlike our ancient ancestors.
The fate of most fetus is to be born and become humans, or other life forms that start out as a fetus.
Cytomegalovirus (CMV) is the most common infection that can be transmitted to a fetus.
Africa has the most developing countries.
China is the most developing Country.
Sudan is a developing country.
All organs of the Fetus are formed during first three months of Pregnancy. So drugs taken during this period have high chances of 'Structural' damage to the Fetus. Afterward 'Functional' damage can occur.So your Doctor will be very careful about drugs given in First Trimester ofPregnancy.
Exposure to a harmful substance during the first trimester of pregnancy is most likely to damage many organs in a developing embryo since this is the period when organs are forming. Any disruption during this critical period can have long-lasting effects on the overall development of the fetus.
the most obvious characteristic of the skin is the colour and the texture.
Color is often considered the most unreliable characteristic of a mineral because it can vary widely even within the same mineral species. Factors such as impurities, alteration, and external conditions can all influence the color of a mineral, leading to inconsistencies in color as a reliable identification feature.
The mass of the fetus increases most rapidly during the third trimester of pregnancy. This is when the fetus experiences significant growth and development, resulting in a noticeable increase in mass and size.
