Answer:
She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant
Explanation:
The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells (e.g. egg or sperm), each with half the number of chromosomes of the parent cell. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. Mitosis includes one division, while meiosis includes two.
What we can observe in order to visualize Mendel's Law of Segregation is homologous chromosomes separating during meiosis I. The correct answer is E.
Answer:
c. lack the enzyme needed to break down cellulose
Explanation:
Starch is the form of carbohydrate which is taken through food by humans and animals and digested by them. Amylase is the enzyme that is used to digest starch in them.
Wood is made up of cellulose and the enzyme which is used to digest cellulose is cellulase. Humans and animals do not have cellulase enzymes therefore they are not able to digest and breakdown cellulose.
Therefore as humans and animals lack enzymes needed to digest cellulose they can not digest wood.
I think the answer is 23?
