Answer:
20 percent
Explanation:
There are some conditions and agents which can impair prenatal development and lead to birth defects or even death knows as teratogens. For example, viruses, drugs, stressors, and malnutrition. Teratogens that can harm the prenatal brain, affecting the future child's intellectual and emotional functioning know as Behavioral teratogens. These increase the risk of harm to developing children. Some can influence the effect of teratogens.
1. Timing--- at which phase of pregnancy, developing organism exposed to the teratogen, either in 1st, 2nd or 3rd trimester.
2. Exposure-- at what dose or frequency of exposure of the teratogen, newborn is going to expose.
3. Genetic variability-- genetic makeup of newborn makes her more susceptible to the effect of a teratogen.
According to literature, 20 percent of behavioral teratogen can affect the newborn.
Answer:
The correct answer will be option-C.
Explanation:
The proton motive force is the force generated by the movement and difference of the charge inside and outside the membrane. The proton motive force is generated due to the electron transport chain as the flow of electron causes the movement of hydrogen ions from the matrix to the inter-membrane space.
This leads to the increase of H⁺ ion concentration in inter-membrane space and lowering of the H⁺ ions in the matrix. This difference in the charges causes the generation of force called proton motive force which helps the synthesis of ATP.
Thus, Option-C is the correct answer.
Answer:
16
Explanation:
A diploid organism that produces gametes will undergo meiosis to do so. Meiosis reduces the chromosomal number in the gametes by half. Hence, each gamete will have 4 chromosomes (haploid,n). Crossing-over will likely occur during the meiotic process leading to recombination in the arrangement of chromosomes in the gametes.
If this occurs, a mathematical expression of 2^n is used to determine the number of possible combinations, where n is the number of chromosomes in the gamete.
Hence, 2^4 = 16 possible combinations of chromosomes in the gamete.

Explanation:
The specialized muscle cells are skeletal muscle cells belonging to the striated muscle cell category. These are the muscles that are utilized for movement, and are organized into compartments of specific muscle tissues all over the body, including the biceps. Structures known as tendons are responsible for attaching skeletal muscles to bones, generally two to three cm long.
