It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.
<h3>What makes Drosophila unique?</h3>
The use of Drosophila over vertebrate models has many technological advantages;
- they are simple and affordable to culture in lab settings,
- have a significantly shorter life cycle,
- produce huge numbers of externally deposited embryos
- may be genetically manipulated in a variety of ways.
<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>
- Drosophila, which means "dew loving," is derived from the Greek word drósos.
- Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
- This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.

Complete question:
Phenotype Genotype Number of Individuals
Long-tailed TT 260
Long-tailed Tt 160
Short-tailed tt 80
If 20% of the long-tailed cats got their tails stuck in something and failed to reproduce, what would be the expected change in frequency of T in the next generation
Answer:
The expected change in allelic T frequencies probably changes from 0.6 to 0.57 in the following generation.
Explanation:
Due to technical problems, you will find the complete question, answer and explanation in the attached files.
Answer:
True
Explanation:
In phase-contrast objective and a phase contrast optical systems is equipped with Light microscope .
Phase contrast microscope is used to differentiate unstained structures in a cell that differ in refractive indices and thickness. Thus it is usefull for examining living unstained organisms.
Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.
Hoping this might help!!!
Answer:
WAVE #3
Explanation:
Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz
C because if there isn’t enough of something, more can be added but if there is max capacity, nothing can be added
