What is the order of phases in mitosis? Question 15 options: Prophase, Metaphase, Anaphase, Telophase Telophase, Cytokinesis, Metaphase, Anaphase Prophase, Telophase, Anaphase, Metaphase Metaphase, Interphase, Anaphase, Telophase.
The steps of mitosis are in the order of prophase, metaphase, anaphase, telophase.
What are mitosis and its four stages?Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei.
Mitosis comprises four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in this strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. The mitotic phase is a relatively short period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for the process of cell division. Interphase is divided into three phases: G1 (first gap), S (synthesis), and G2 (second gap).
Thus, the order of phases in mitosis is in the order of prophase, metaphase, anaphase, telophase.

What is the difference between a benign tumor and a malignant tumor? View Available Hint(s)for Part A Benign tumors will not kill you; malignant tumors will. A benign tumor is a mass of essentially abnormal cells; a malignant tumor is an abnormal mass of essentially normal cells. Benign tumors do not metastasize; malignant tumors do. Benign tumors metastasize; malignant tumors do not.
Answer:
These cells can form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, which means that it can grow and spread to other parts of the body. A benign tumor means that the tumor can grow, but it will not spread.
A population of kangaroos have a gene with two alleles that affects birth weight. AA individuals are much heavier at birth. Aa individuals are medium size at birth and aa individuals are very small at birth. Large babies sometimes die during the birth process and very small babies often die from illness. Show the selection that you think is taking place on the population
Based on the process of natural selection, individuals with genotype Aa are naturally selected for survival.
What is natural selection?Natural selection is the process by which individuals who possess features or structures best suited for survival in their environment are selected for survival.
In the population of kangaroos having a gene with two alleles affecting birth weight, it is observed that individuals with Aa geneotype for medium birth weight survive.
Therefore, individuals with genotype Aa are naturally selected for survival.

Jose is growing pea plants in his garden. He notices that some plants have green pods, while others have yellow pods. He researches the species he planted and finds that green pods are dominant to yellow pods.
According to Mendel's law (principle) of dominance, which of the following statements can be said with certainty?
Answer:
The yellow pods will be destroyed.
Explanation:
His law states that one of the species will be completely destroyed if one is dominant. His guinea pig example illustrated this. The guinea pig was the framework of his principle, and relates almost exactly to this situation, except for the pods and pigs difference.
Answer:
- The plants with yellow pods do not have an allele for green pods.
- The plants with green pods might be homozygous or heterozygous for pod color.
Explanation:
Gregor Mendel's law (principle) of dominance states that some alleles are dominant, whereas others are recessive. An organism with a dominant allele for a particular trait will always have that trait expressed, or seen, in the organism. An organism with a recessive allele for a particular trait will only have that trait expressed when the dominant allele is not present.
The question states that Jose's pea plants can have two forms of the pod color allele—a dominant green allele and a recessive yellow allele.
His plants with yellow pods must be homozygous for the recessive yellow allele. Therefore, the plants with yellow pods cannot have an allele for green pods.
His plants with green pods could have two alleles for green pods or one allele for green pods and one for yellow pods. Mendel's law of dominance states that an organism needs only one copy of the dominant allele for its trait to be expressed. So, the plants with green pods might be homozygous or heterozygous for pod color.
Incomplete dominance is a condition in which one allele is not completely dominant over another, resulting in a phenotype (outward appearance) somewhere between the two homozygous forms. Since it is known that green pods are dominant to yellow pods and no other pod colors were produced in Jose's garden, it can be concluded that the plants are not displaying incomplete dominance.

How is the goal of evolutionary classification different from linnaean classification.
Answer:
The goal of evolutionary classification
Explanation:
The goal of evolutionary classification is to group species into larger categories that reflect lines of evolutionary descent, rather than overall similarities. The goal of linnaean classification is to group species into larger categories based on physical characteristics
In domestic swine there is a dominant allele which produces a white belt around the body. The recessive allele produces uniform body color. One farmer wants to produce only belted hogs, and another wants only uniformly colored animals. Which farmer would have an easier time producing a true-breeding herd? Explain why. Tell how each farmer would proceed. (Hint: how could you tell if a herd was true-breeding?)
Answer:
The first farmer
Explanation:
The belted allele is dominant and would therefore have a higher chance of showing up in the hog.

Answer:
Explanation:
The larger the difference in electronegativity between the two atoms, the more electronegative that bond is. To be considered a polar bond, the difference in electronegativity must be large. The dipole moment points in the direction of the vector quantity of each of the bond electronegativities added together.
