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>
Explanation:
<u>-how long it takes for the voltage-gatedNa+ channels to close at the end of an action potential</u>
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient.
The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.

Answer:
OmRNA
Explanation:
The end product of transcription is RNA.
Answer:
Zero %
Explanation:
Male is BBCc and Female is bbcc , then
BBCc x bbCc will always give the B allele in all the F1 generation combinations. That is, all individuals will be coloured, although a half can be straight coat.
If you use a Punnett square, it will be easy to visualize the cross
An example of two commonly exploited fungal species are Sacchromyces cervisiae and Streptococcus thermophilus.
Sacchromyces cervisiae is mainly used for bread production. Sacchromyces cervisiae is a yeast and as such is very active metabolically. Through its metabolism, produces
from the fermentation of the cereal's sugars to alcohol<span> which makes bread rise.
</span><span>Streptococcus thermophilus are important on the yogurt industry. These bacteria ferment lactose (milk's sugar) producing lactic acid turning milk into yogurt.</span>
