The specification of the anterior-posterior axis in Drosophila embryos is initially controlled by various gene products that are
mojhsa [17]

Answer:

It is possible to determine their functions and to identify the mechanism involved in their mode of inheritance  

Explanation:

Matrilineal inheritance refers to the inheritance of genes directly from the mother, it either through the inheritance of mitochondrial DNA or by the epigenetic mechanism of genomic imprinting (in the case above indicated, maternal imprinting). By mutating genes which are inherited from the mother it is possible to study their functions as well as their mode of inheritance. By using a reverse genetics approach, many maternal imprinted genes have recently been identified to be involved in embryo development, especially in model organisms like <em>Drosophila</em>.

True or false: The energy contained in the food we eat directly powers all of our cellular activities. If false, please make it
Gwar [14]

Answer:

False

"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".

Explanation:

The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.

ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
