Explanation:
Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.
<u>It includes the following phases -
</u>
1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .
2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .
3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .
4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.
5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.
6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.
Answer:
Spend more time outdoors, eat more red meat, supplement their deficiency with vitamins
Explanation:
Hello!
Vitamin D is a very important micronutrient within our bodies. This is due to its ability to regulate the amount of calcium and phosphate in the body. If a patient is Vitamin D deficient it can lead to a magnitude of problems such as bone deformities such as rickets, significant loss in bone density and depression. Thankfully, Vitamin D is one of the easiest vitamins to obtain. If a patient is not at risk for Melanoma, or other forms of skin diseases, they can obtain Vitamin D by simply spending more time outdoors in direct sunlight. Vitamin D can also be obtained through altering ones diet to include more red meat, egg yolks, liver, fish, and select breakfast cereals. If these options are not applicable to a patient a healthcare physician can supplement them in the form of Vitamin D tablets of varying concentration.

Current Procedural Terminology
Current Procedural Terminology (CPT) is a medical code set that is used to report medical, surgical, and diagnostic procedures and services to entities such as physicians, health insurance companies and accreditation organizations. Might not exactly be an answer, but I hope it helps
Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
