Answer:
The correct option is <em>B. 25 %</em>
Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.
Archaebacteria are obligate anaerobes, i.e., they flourish in the strict absence of oxygen., and that is why only they can undergo methanogenesis.
The cell membranes of the Archaebacteria are composed of lipids.
The rigid cell wall provides shape and support to the Archaebacteria.

Answer:
1. Scientific probe.
2. Weather station.
3. Weather station.
4. Scientific probe.
Explanation:
1. <em><u>Scientific probe</u></em>: measures a variety of data, including pH levels and conductivity. Thus, a scientific probe is a device that is typically used for measuring science-based data such as electrical conductivity, pH levels, salinity etc., of various materials.
2. <em><u>Weather station</u></em>: measures temperature, humidity, wind speed, and pressure. Basically, a weather station comprises of various devices for measuring atmospheric conditions such as thermometers, barometers, hygrometer, wind vane etc., used for the measurement of temperature, atmospheric pressure, relative humidity and wind speed respectively.
3. <em><u>Weather station</u></em>: gathers information about local atmospheric conditions.
4. <em><u>Scientific probe</u></em>: can digitally record data, such as flow rate.
D.) people may disagree in their interpretations of instant data.
