Geiger-Muller tube is instruments requires you test three times the background of the work area.

<u>Explanation</u>:

These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds

Which of these describes a situation where natural selection could lead to evolution?
Gennadij [26K]

Answer:

B. Predation removes slower antelope from the herd.

Explanation:

Natural selection is defined as the differential survival and reproduction of individuals due to differences in the physical characteristics.

A predator-prey relationship results in a very fast-slow dynamical system for rapid predator evolution.

Predation removes slower antelope from the herd and hinders passage of the slow trait to offsprings. The ones who are fast reproduce and give birth to other fast animals.

Which guinea pig parent(s) in Punnett Square B is homozygous? Which is heterozygous? Explain how you know.
ArbitrLikvidat [17]
You did not provide an image for me, but I can explain.

Homozygous, with the root homo, means same. Therefore, a guinea pig parent with homozygous traits would have the traits being the same - either both recessive or both dominant, ie TT, tt.

Heterozygous on the other hand means different, therefore the traits would be one dominant and one recessive - for example, Tt.

If for the punnet square it has different traits (Combo RB for red and black or combo RW red white for like fur color) than heterozygous would be any that isn’t like TT or tt or any other letters used.

Hope this helps!
