Answer:
Sequential or integrated screening
Cell-free fetal DNA testing
Proteins in your blood that can mean your baby has a higher risk of birth defects
Explanation:
Sequential or integrated screening
Sequential screening is a test that uses a mix of ultrasound and blood tests to look birth defects at 10 and 13 weeks of pregnancy.
Integrated screening is similar and is done at around 12 weeks and is slightly more accurate
Cell-free fetal DNA testing is testing the baby's DNA that ends up in the mothers blood for signs of birth defects
Answer:
Examples of scientific theories in different areas of science include: Astronomy: Big Bang Theory. Biology: Cell Theory; Theory of Evolution; Germ Theory of Disease. Chemistry: Atomic Theory; Kinetic Theory of Gases.
Answer: Usually a human body cell contains 46 chromosomes. We get 23 chromosomes from dad and 23 chromosomes from mom for a total of 46.
Answer:
The correct answer will be option-E.
Explanation:
The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.
The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.
The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism
Thus, option-E is the correct answer.
Answer:
The Gibbs free energy (G) of a system is a measure of the amount of usable energy (energy that a job can do) in that system. Changing Gibbs free energy during a reaction provides useful information about the energy and spontaneity of the reaction while Helmholtz free energy is a thermodynamic property that can be used to predict whether a process occurs spontaneously at constant volume and temperature.
Explanation:
<u>Gibbs free energy is the most used for biological systems</u> since it allows to relate the enthalpy change of the reactions occurred in the system and determine for example if they occur spontaneously or not, if they produce heat or absorb heat.
On the other hand, Helmholtz energy (also called Helmholtz function, Helmholtz free energy or work function) is an extensive quantity, thermodynamic potential and state function, of a thermodynamic system that measures the work obtainable in a closed system, in constant temperature conditions. . It does not depend on the process suffered, but on the final and initial state of the system
