Explanation:
DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint. Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases. Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme. I hope this makes sense to you!

In your own words, explain how background noise detected in space provides evidence for the Big Bang Theory.
Answer:
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.
Explanation:
Answer:
Cosmic microwave background radiation (CMR) found a mysterious microwave a signal causing background noise in the radio telescope the signal came from everywhere. The early universe should have been very hot the cosmic microwave background radiation (CMR) is the remnant heat left over from the big bang.

Explanation:
Describe the situations in which a normal human cell would enter the cell cycle and undergo mitotic cell division. Explain how spindle fibers help ensure the products of mitosis are two identical cells with a full set of chromosomes.
Answer: An example of a specific case is when a skin lesion occurs. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other. The spindle fibers are structures formed by microtubules extending from one pole to another to orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase.
Explanation:
Mitosis is a process of cell division that occurs in eukaryotic cells, i.e. cells that have a nucleus where their genetic material is located. This process generates two identical cells with the same DNA, that is, with two identical nuclei, so it does not provide genetic variability except in case of specific mutations. The objective of mitosis is cell multiplication while preserving genetic information. But in general, in mitosis there is an equal distribution of the cell nucleus as well as the rest of the cell content.
The phases of mitosis are as follows:
Interface: The cell duplicates its organelles and its DNA to have twice everything before division.Prophase: The nuclear membrane breaks, the chromosomes condense, the centrosome duplicates and migrates to the opposite poles of the cell forming microtubules. Also, fibers of the mitotic spindle are formed. Prometaphase: The microtubules invade the space where the genetic material is.Metaphase: The replicated chromosomes line up in the middle of the cell, called the equatorial plane.Anaphase: Microtubules separate chromosomes towards the opposite poles. Telophase: The nuclear envelope is re-formed from the remaining fragments of the original.Cytokinesis: A cleavage groove is created in the common cytoplasm of the two new cells where the chromosomes were aligned. The cytoplasm is thus strangled until the membrane allows total separation.Mitosis is then a cellular process that occurs in multicellular organisms to repair damaged tissue, or for growth or development. An example of a specific case is when a skin lesion occurs. When a person suffers an injury, many reactions take place in the repair process to repair the damage including inflammatory, proliferative, and remodeling phases. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other, to have the same genetic fingerprint and the same function.
The spindle fibers are structures formed by microtubules extending from one pole to another. The kinetochore microtubules attach to the kinetochore, a structure that forms at the centromere of each duplicated chromosome, and orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase and attracting the newly separated chromosomes to the poles during anaphase.
Spindle fibers has a great contribution in the process of mitosis.
The spindle fibers help to ensure the products of mitosis which is two identical cells with a full set of chromosomes due to attracting the chromosomes towards the poles. Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres and drag the chromosomes towards the pole.
This movement of chromosomes leads to the formation of one parent cell into two daughter cells having equal and same set of chromosomes so we can conclude that spindle fibers has a great contribution in the process of mitosis.

Hope this helps!
According to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.
What is Community?A Community may be defined as a group of individuals belonging to different species living in the same area at a given time.
The individual is the unit of the population, while the population is the unit of evolution. This form of evolution is significantly required in order to construct a community where the different groups of individuals of different species are gathered in such a way that one depends on another.
Therefore, according to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.

ANSWER ASAP PLEASE. What process occurs after glycolysis if oxygen is still available for cellular respiration?
Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.
What is Kreb's cycle?Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.
In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.
Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.
