<span>Based on a simple Punnett square, you could predict that one of the offspring (with the genotype yy) would present with red leaves. The other three offspring would present the phenotype of the yellow leaves, because the dominant gene (Y) is present (genetypes Yy, yY, and YY).</span>
Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.
Answer:
The frequency would be stable.
Explanation:
Based on the most common symptoms of cystic fibrosis, the disease only appears on adults and elderly. This feature means that the frequency of the disease would not drop or raise because they would still reproduce and pass the allele from generation to the next, maintaining the frequency stable.
Answer:
<u>independent variable:</u> size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
<u>independent variable</u>: size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Answer: The narrator can be a witness or a reteller of events.
Explanation:
A first-person narration is a way of storytelling in which the storyteller narrates the first hand experiences. The narrator recollects or recounts the events specific for a story through own point of view introducing oneself as first person.
