Centrioles are organelles that are found only in animal cells and they produce D) flagellum and centrosomes.
Centrosomes help organize the microtubules present in the animal cell during cell division and also regulate the cell cycle.
Furthermore, the flagellum produced by centrioles in sperm cells help the cell move towards the egg and cause fertilization.
Prokaryotes do not have a nucleus or membrane bound organelles while eukaryotes do
Answer:
Option B is correct.
Explanation:
Carbohydrate fermentation test; its main purpose is to know if a bacteria can ferment a specific carbohydrate or not. The test can be used for distinguishing bacterial species.
When fermentation of carbohydrate occurs, gaseous acids are produced. This production of the acid lower the pH of the medium undergoing the test, which can be detected by the color change of the pH indicator.
The Color changes only when sufficient amount of acid is produced. Phenol red can easily detect single acid production but METHYL RED NEED MORE ACID.
Answer:
100%
Explanation:
The probability is shown by the punnet square below. While the genotype of 50% of the offspring may be heterozygous, since the allele for straight hair is dominant over that of curly hair, their phenotypes too will be of straight hair similar to the homozygous dominant offspring.
