The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
Cells divide in an effort to reproduce and create more of themselves to keep their larger- encompassing species sustained.
Answer:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain. The pyramid base contains producers—organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers

Answer:
The correct option is : c. gas gangrene
Explanation:
Gas gangrene is a serious bacterial infection caused by the infection of the Clostridium perfringens bacteria. This bacteria is always present in the nature and is a rod-shaped, gram-positive bacteria, that belongs to the Clostridium genus.
This disease can cause gas production in gangrene, death of the muscle tissues and also sepsis.
<u>Therefore, Gas gangrene is most associated with the bacteria Clostridium perfringens.</u>
