Genetic defect is the most likely cause for a miscarriage during the first three months of pregnancy. The most likely time for a miscarriage is during the first three months of pregnancy. It is the common type of pregnancy loss or spontaneous abortion, it is the natural death of an embryo or fetus before it is able to survive independently.
It is believed that this happens because some signals that regulate development are the same between different species and because <span>they share ancient genes. </span>These ancient genes are expressed during a middle "phylotypic stage" of embryonic development for all species.
For example, human and animal embryos go through very similar stages of early development and share similar features such as tails and gill-like structures. The major difference appears to be how long it takes to reach each of these same stages.
Answer:
I believe the answer is 3/4
Explanation:
18 and 24 both have common factors of 6. So you would divide both 18 and 24 by 6. 18÷6=3 and 24÷6=4. 3 and 4 don't have any common factors so this is the lowest it can go and can't be divided anymore. So, 3/4 is the simplest form. Hope I helped! :)
Answer:
DNA
proteins
genes
chromatin
chromosomes
chromosome
Explanation:
The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into chromosomes. Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.
