Answer:
Binary fission is a method of asexual reproduction in prokaryotes such as bacteria. The advantages of binary fission is that this process requires only one individual. Secondly, it is a fast process of division as some in some of the bacteria divides in every 20 minutes. Binary fission produces offspring without genetic variation.
The percentage of the offspring that will be expected to have the TTYy allele combination is 25%.
A cross or breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.
Two heterozygous plant crosses will result:
T T Y y
T TT TT y Yy yy
t Tt Tt y Yy yy
The ratio of TT = 1/2 The ratio of Yy = 1/2
The total ratio of TTYy is 1/2 x 1/2 = 1/4 = 25%.
Therefore, 25% of the progeny should carry the TTYy allele combination, according to expectations. The offspring produced is heterozygous.

Answer:
1/4 in fraction and 25% in percentage
Explanation:
Study the graph below. At what depth does the thermocline begin?
A line graph relating ocean depth to water temperature. At 0 meters, temperature is approximately 27°C. At 100 meters, temperature is approximately 24°C. At 200 meters, temperature is approximately 11°C. At 300 meters, temperature is approximately 8°C.

0 meters
100 meters
200 meters
300 meters
Answer: 100 meters
Explanation:
The thermocline begins at 100 meters of depth. Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth. From the given graph it cam be seen that at 100 meters the thermocline begins such that the temperature drops from to.

Correct answer: B). People are warned to avoid eating shrimp and lobster.
People are warned to avoid eating of lobster and shrimp that would be least likely to be seen on a pamphlet of red tide because lobsters and shrimp are not affected by the red tides.
The fishes that are affected by red tide are shellfish and oysters. so if someone consumes shrimp and lobster then it would not create any problem related to red tide. Red tide is considered harmful to humans and they can cause death if consumed.
The information pamphlet for red tide is ‘People are warned to avoid eating shrimp and lobster’. Because eating one will likely cause death du tot poisononing.
Answer:
Receiving the same amount of light intensity and water. Being grown in the same type of soil ensures that the above listed constant variable is maintained to ensure that any changes to rate of plant growth is solely due to changes in pH level.
Explanation:
The variable that u are testing Is change in pH level. Hence, to ensure results are reliable, u need to hold the other variables constant.
To increase the validity of this experiment, the researchers should replicate the experiment under different conditions or with a larger sample size. Further, running additional experiments with watering solutions having different pH levels could help in understanding the optimal pH for radish growth.
The activity that might aid in increasing the validity of this experiment on whether the pH of water affects the growth of radish plants is the replication of the experiment, preferably under different conditions or with a greater sample size. More experimental groups with varying pH levels may also make the results more valid and reliable. This means, instead of just having a group with a pH of 3.0 and another with a pH of 7.0, the researchers could consider using watering solutions with a pH of 4.0, 5.0, 6.0, and so on. This would help in pinpointing an optimal pH for the growth of radish plants and make the results of the study stronger.
