What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answers
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

In this lab, you will simulate birds with three different beaks. After watching the birds feed, you will remove fruit to simulate a change in the environment. What question are you answering by doing this observation?
Answers
Answer:
How does a change in food resources model the type of beaks in birds?
Explanation:
We know that phenotype results from the interaction of the genotype and the environment. Any change in the environment produces a change in the phenotype of the animals. By performing this experiment, we probably want to know the influence of the environment on animals. In this particular example, we change a source of food by removing fruit (which would be acting as the independent variable of the experiment) and evaluate its effects on the birds´ beak (the dependent variable). Which of the three different beaks increases their frequencies by removing the fruit, and which one decreases its frequency.
So here, the absence of fruit is acting as a selective ecological pressure on birds. It is modeling birds´ beaks and adapting animals to feed on some other resource.
Change in food resources ---> Selective ecological pressure.Change in beaks frequency----> Adaptative response.In cherry tomatoes, red color (R) is dominant to yellow color (r). If two heterozygous plants are crossed, what percentage of the offspring will be yellow?
Answers
Answer:
50
Explanation:
If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.
Explain h0mozygous and heter0zygous?If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.
In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).
Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.
In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.
Thus, That makes your percentage A. 50%.
