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.
A DNA is made up 4 nucleotides bases The four ntd bases are ADININE, THYMYNE...
Answer:
chips are a simple carbocarbohydrate and celery is a complex carbocarbohydrate
Explanation:
There is a direct relationship between a glucose molecule and the products it makes during cellular respiration because of the same number of molecules.
<h3>What is cellular respiration?</h3>
Cellular respiration is defined as the process by which oxygen combines with food molecules i.e. glucose changing the chemical energy in these substances into energy molecules along with the production of waste products such as carbon dioxide and water. During cellular respiration, a glucose molecule is broken down into carbon dioxide and water. Some ATP is produced directly in the reactions that change glucose into other forms. Much more ATP is produced in a process known as oxidative phosphorylation. The purpose of cellular respiration is to provide cells with the energy they need to do their function while on the other hand, photosynthesis is a process in which glucose is produced from the combination of reactants such as carbon dioxide and oxygen.
So we can conclude that the products of cellular respiration depend on the glucose molecule.

Answer:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
Explanation:
cDNA is the acronym for complementary DNA. This DNA is a single or double stranded moolecule that is synthesized from a messenger RNA molecule. This molecule is used in studies that aim to clone eukaryotic genes in prokaryotic individuals. The result of this is the expression of a protein from a eukaryotic individual in prokaryotic individuals.
To form a double-stranded cDNA molecule, the following steps would be required:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
