Explain how can variations lead to adaptations and evolution

Biology
1 answer:
Romashka [77]3 years ago

Which reading is expected from a thermometer near Earth’s surface during a period of freezing rain?
frosja888 [35]
Freezing rain refers to the rain that falls through a shallow layer of cold temperature at zero degree Celsius or below zero degree Celsius near the earth surface. Celsius and Fahrenheit are two types of measurement that are used to measure temperature. The freezing temperature of water is zero degree Celsius. Zero degree Celsius is the same thing as 32 degree Fahrenheit. 
Thus, the thermometer reading that is expected from a thermometer near the earth's surface during a period of freezing rain is 32 degree Fahrenheit.

A lizard with a striped tail and a normal head is crossed with one having a normal tail and a spotted head. All the F 1 progeny
gavmur [86]

Answer:

9 normal : 3 striped : 3 spotted: 1 striped and spotted.

Explanation:

The F1 progeny contains no spots or stripes and are considered as normal, it means normal tail and normal head are dominant on their alternative traits. So, it means that the F1 progeny are heterozygous in nature for both of the traits.

The cross between 2 F1 progeny is dihybrid cross of lizards (heterozygous) which will produce offspring in 9:3:3:1 ratio, where 9 are normal, 3 striped which are dominant in the one character, 3 spotted which are dominant in other, and 1 will be stripped and spotted which is recessive in nature.
