Answer:

By test crossing the pea plant with a homozygous recessive pea plant

Explanation:

<em>A test cross involves crossing of an individual with doubtful genotype with an individual that is homozygous recessive for the same trait in order to determine whether the individual with doubtful genotype is homozygous or heterozygous for the trait in question.</em>

Assuming the gardener's pea plant is homozygous (SS), one would expect all the progeny to be smooth seeded when the pea plant is test-crossed with a homozygous recessive pea plant such that

SS x ss = Ss, Ss, Ss and Ss (assuming the allele for seed texture to be S)

Assuming the gardener's pea plant is heterozygous (Ss):

Ss x ss = Ss, Ss, ss and ss. Hence, one would expect 50% of the progeny to be smooth seeded and 50% to be wrinkled seeded.

Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power home
Keith_Richards [23]
Geothermal is a renewable energy, because it is from the heat produced by the earth. The earth gets heat from the sun, which will be there for the next million of years. Geothermal has benefits, because if we harness the use of it, instead of mining out all of our coal and oil, we can use this for a long run, and only leave non-renewable energy resources for backup. However, there are consequences to communities and surroundings. The geothermal only benefits when the earth is warm. When the earth becomes too warm, we wouldn't even need the energy anymore cuz everythings dead. So we can use this, but overall we must try to lower the amount of resources that produce this thing as possible.. ( use other renewable energy)

hope this helps

In which part of the body would you find striated muscle tissue with relatively small cells that have one or two nuclei?
Ilya [14]

Answer: Heart

The striated muscle tissue with relatively small cells that have one or two nuclei can be found at the heart. The intracellular calcium signaling is an intrinsic component of signal transduction pathways that regulate vital aspects of muscle function including excitability, force production, protein synthesis, and energy expenditure that occurs in the striated muscle tissue of the heart.

Introns and transposons can act as sites where recombinational crossovers occur. Transposons can also catalyze genetic rearrange
Feliz [49]

Answer:

False

Explanation:

Rearrangements on introns and transposons usually don't cause severe consequences because those sequences are not part of coding genes and therefore cannot code for proteins, and if a rearrangement occur within a coding sequence of a gene might cause an incomplete and non-functional protein causing severe consequences to expression levels of that particular gene.
