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>
Answer:
D. Sunlight
Explanation:
Since photosynthesis provides the energy the plant needs for growth, lack of light will stunt the plant's growth.
When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.
Answer:
The endomembrane system includes the nuclear envelope.
Explanation:
The endomembrane is composed by the endoplasmic reticulum (ER) and the golgi apparatus. Its main function is to synthesize proteins (rough endoplasmic reticulum studded with ribosomes) proteins can also be modified in the ER of pass to the golgi apparatus where they can be modified and sort to be packed in vesicles to be exported to different parts of the body, for example hormones.
the nuclear envelope only holds the DNA and it´s not involved in protein synthesis.
Atoms, molecules, cell membranes, then cell (in order from smallest to biggest).
