To maintain your body temperature, your body converts chemical potential energy into thermal energy.

Answer:

Option D, TT ´ tt

Explanation:

Allele for tallnes "T" is dominant over the recessive allele "t"

The genotype of a heterozygous tall offspring will be "Tt"

When a cross is carried out between "TT " and "tt" , the following offspring are produced -

T T

t Tt Tt

t Tt Tt

All the offspring have genotype "Tt" which is a heterogyzous allele pair.

Since "T" is dominant over "t", all the alleles would be heterozygous tall.

Thus, in order to produce 100 percent heterozygous tall offspring, the cross must be carried out between "TT" and "tt".

Option D is correct

The layer which protects the earth is referred to as magnetosphere.

Magnetosphere is termed as the region of space which surrounds astronomical object by way of magnetic fields.

They create planets which generates planets in magnetic field which include fields where they can occur in stars through interaction of plasma.

Magnetosphere blows away particles from the earth and also from the sun.

As per the details given, the offspring from this cross are expected to have a 1:2:1 ratio of homozygousred, heterozygous red, and homozygous white flowers, respectively.

The expected result of crossing two heterozygous red flowers (where the white flower trait is recessive) is as follows:

• There is a 25% chance that homozygous red flowers (RR) will display the dominant red characteristic.
• 50% chance of obtaining heterozygous red flowers (Rr), which carry the recessive white allele but nevertheless display the dominant red characteristic.
• Having homozygous white flowers (rr) with the recessive white trait is a 25% likelihood.

Thus, there should be a 1:2:1 ratio of homozygous red, heterozygous red, and homozygous white flowers in the progeny of this cross.

Your question seems incomplete, the probable complete question is:

Two heterozygous red flowers (white flowers are recessive) are crossed. What is the expected outcome when two heterozygous red flowers (where the white flower trait is recessive) are crossed?
