The correct answer would be A. Repaired - Preserved is incorrect
Answer:
The scanning electron microscope allows the elaboration of an image in which the surface characteristics of the sample are reflected, thus providing sufficient information on the shapes, textures, and chemical composition of the constituents.
Explanation:
The scanning electron microscope uses electrons instead of light for imaging.
To achieve this, the team has a device that produces an electron beam that allows the entire sample to be illuminated and, through different detectors, the electrons that are produced from the interaction with the surface of the sample are later collected.
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.
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.
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.

Answer:
Explanation:
Fertilization is the process by which haploid gametes (n- sperm and egg) fuse together to form a diploid cell called ZYGOTE. A gamete is a reproductive or sex cell produced by a sexually-reproducing organism during meiosis. Diploid organisms produce gametes that contains one set of chromosomes i.e haploid. Male organisms produce sperm while female organisms produce egg/ovum.
To ensure that the zygote, which grows into the full organism, has the correct number of chromosomes, only one sperm can fuse with one egg. It is worthy to note that, fertilization can either occur internally (union of sperm and egg within the body of the female parent) or externally (joining of gametes outside the body).
