Weights (kg) of poplar trees were obtained from trees planted in a rich and moist region. The trees were given different treatments identified in the accompanying table. Use a 0.05 significance level to test the claim that the four treatment categories yield poplar trees with the same mean weight. Is there a treatment that appears to be most effective? E Click the icon to view the data table of the poplar weights. Determine the null and alternative hypotheses. Но H1

Answers

Answer 1
Answer:

Answer:

Null hypothesis (H0): The four treatment categories yield poplar trees with the same mean weight.

Alternative hypothesis (H1): The four treatment categories yield poplar trees with a different mean weight.

Based on the data table, it appears that Treatment A yields the highest mean weight for the poplar trees. Therefore, Treatment A appears to be the most effective.

Answer 2
Answer:

Final answer:

To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight, while the alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.

Explanation:

To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. This means that if the p-value is less than 0.05, we will reject the null hypothesis and conclude that there is evidence to support the claim that the treatment categories yield poplar trees with different mean weights. On the other hand, if the p-value is greater than or equal to 0.05, we will fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the treatment categories yield poplar trees with different mean weights.

The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight. The alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.

The type of insects and the stage of the insect's life can give some indication on how long a body has been dead. True False

Answers

In general, no, it is false that the type of insects and the stage of the insect's life can give some indication on how long a body has been dead. 

Answer: True

Explanation:

Forensic entomology is a sub-discipline of forensic science. It deals with the study of insects and their life cycles which are found in close proximity of the dead body. The type of insects grow over the body depends upon the stage of decomposition of the body. Also the life cycle varies depending upon the feeding nature of the immature stages of the developing insect on the dead body. More deformed body by the insects as evident by the colonization of eggs, and other immature stages as well as the mature insects can give indication of the time since death.

neumatophores are erect roots that are some form of upward appendage or extension of  the root system can obtain oxygen in an otherwise anaerobic substrate They also help in aeration. eg red mangrove,swampy plants:
pneumatopores specialized 'breathing' root developed in some plant species that grow in waterlogged or strongly compacted soils, e.g-mangroves. The aerial part of the root contains many pores, enabling gas exchanges with the atmostphere. Internally, a well developed system of incellular spaces allows gases to diffuse throughout the submerged portion of the roots

Explain incomplete dominance using snapdragon flowers as an example

Answers

Incomplete dominance is a type of inheritance pattern that occurs in snapdragon flowers.

When none of the factors of a gene is dominant, the phenotype of a heterozygous dominant individual is a blend of dominant and recessive traits called incomplete dominance inheritance pattern.

  • flower color in Mirabilis jalapa (Snapdragon)
  • The red flower is the dominant character and the white flower is the recessive character.
  • There is the blending of the two alleles.
  • The flowers in the F1​  a generation will be pink in color due to the mixing of the alleles

Thus, Incomplete dominance is a type of inheritance pattern that occurs in snapdragon flowers.

Answer:

Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant.

Explanation:

when plants have a red color the dominant trait  the snapdragon flower is crossed with a plant having white color the recessive trait it resulted with a production of the plants with pink flowers you get the intermediate of a red and white flower.

Another Answer:

Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

How has climate influenced the size of house sparrows? a. They have gradually become smaller in colder parts of the country.
b. Their size has not changed in response to climate.
c. They have gradually become larger in colder parts of the country.
d. Their size has increased in response to heavy rainfall.

Answers

The study of living things is called biology. There are two types of living are these are plants and animals.

The correct answer to the question is A that is They have gradually become smaller in colder parts of the country.

What is climate?

  • Climate is the long-term weather pattern in an area, typically averaged over 30 years.
  • More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years.

According to the question, the size is directly proportional to the temperature of that given area. Colder the climate smaller the organism and vice versa. This statement is given by Allens and is known as Allens rule

Hence, the correct answer is option A.
