The phenotypic ratio in this case is 9:3:3:1.
<h3>
What is phenotypic ratio?</h3>
- A phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
- The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
- A test cross is a technique used in genetics to investigate and collect potential genotypes and traits of offspring of organisms. An organism's genotype is its genetic make-up; it lists the alleles and genes that the particular organism possesses.
- The expression of genes and alleles in observable traits is referred to as the phenotype. Eye color, height, and even hair texture are examples of phenotypes.

Question:
Two pea plants are crossed. Both are heterozygous for purple blossom color, while one is homozygous for being short and the other is heterozygous for being tall. In pea plants, tall is dominant to short, and purple flowers are dominant to white. Find the phenotypic ratio.

Hey there again, Queen Messy here!
A tsunami is a series of ocean waves with very long wavelengths (typically hundreds of kilometres) caused by large-scale disturbances of the ocean. The deeper the water, the greater the speed of tsunami waves will be. Tsunami retain their energy, meaning they can travel across entire oceans with limited energy loss.
Yes. All tsunamis are potentially dangerous, even though they may not damage every coastline they strike. A tsunami can strike anywhere along most of the U.S. coastline. The most destructive tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska, and Hawaii.

Nucleolus is the Answer, Nucleolus, Nucleus, then Cell Membrane
Answer:
first-level consumers- about 100units
Second-level consumers- about 10units
Third-level consumers- about 1unit
Explanation:
A food chain represents the series of energy transfer from one organism to another. This energy is transferred when one organism feeds on another organism. A food chain always starts with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. The producer creates the energy that is transferred as the food chain progresses.
However, only about 10% of the available energy in one organism is transferred to another, this is because most of the energy (about 90%) is lost as heat when the organism undergoes metabolic activities. Hence, if 1000units of energy are available at the producer level, a primary/first level consumer will feed on the producer and 10/100 × 1000 = 100units of energy will be available for the primary/first level consumer.
Likewise, 10% of 100units= 10 units of energy will be available for the second level consumers when it feed on the first level consumers. Lastly, 10% of 10units = 1 unit will be available for third level consumer when it feeds on second level consumer.
Oxygen makes up 20% of the atmosphere while nitrogen makes up 78%. The other two percent is made up of other gases. Population growth would slow. Organisms need water to survive and if there is a limited amount of water, populations will decline.
