The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.
Answer:
The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.
Explanation:
As you can see in the attached table
1. For the size of the flagella we gave that:
- 241 organisms have long flagella
- 79 organisms have short flagella,
As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.
2. For the number of vacuole we have:
- 247 organisms have one vacuole
- 73 organisms have two vacuole
As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.
Then
Dominant phenotypes = Long flagella and one vacuole
Recessive phenotypes = Short flagella and two vacuoles
Answer:
a) During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
Identical twins are formed through the process of meiosis where a fertilised egg separates to form two identical cells with a common genetic information.
Fraternal twins on the other hand are developed from the fertilisation of two different eggs and two sperm cells. This type of twins possess unique genetic information.
Taenia saginata/Taenia solium are commonly known as tapeworms is a <u>true</u> statement.
Explanation:
Tapeworms are long segmented parasitic flatworms which reside in the intestines of the host’s body. They belong to the phylum Platyhelminthes and scientifically called the Cestoda.
Tapeworm belonging to the Taenia species like the T. saginta, T. solium, T. asiatica etc causes parasitic infections called Taeniasis in the human body and affects the intestines.
Taenia saginata is the tapeworm which resides in pork and Taenia soleum resides in beef.
Humans can be infected with tapeworms when raw or improperly cooked pork or beef is consumed
