Describe a phase of mitosis?
Mitosis is the division of a parent cell into two daughter cells which contain the genetic material which is exactly similar to parents. The daughter cells are often called as clones.
What is Mitosis?
Mitosis is also known as Equational division. Mitosis is the process of cell division, in which the nucleus undergoes division in eukaryotic cells that occurs when a parent cell undergoes division to produce two identical daughter cells.
During the process of cell division, the karyokinesis is followed by the cytokinesis. Karyokinesis is the division of nucleus and it is divided into four phases: Prophase, Metaphase, Anaphase, and Telophase. In the prophase of mitosis, the spindle fibers starts attaching to the chromatids of chromosomes and the chromatids becomes distinct which are then arranged on the equatorial plane and later divides into two daughter cells.

Which of the following is a distinction between the innate and adaptive immune systems?
Answer and Explanation:
The innate system is basically a primitive one shotgun defense and elements of it are present even in plants. The adaptive one ia a more recent evolutionary process and is the rifle shot through the heart. Antigen>to lymphocyte, recognition as enemy> plasma cells, specific antibody production short term Igm then long term IgG> other cell populations that remember the beast and keeps their sights on further invaders of the same type. That memory can last many years even a whole lifetime.
The natural defense mechanism is essentially a innate defense, and plants even have parts of it. The adaptation process is more recent and is represented by the rifle shot to the heart.
What is an immune system?The immune system is a collection of interconnected biological systems that work together to defend an organism against illness. It recognizes and reacts to a wide range of infectious agents, from viruses to worms that are parasitic, as well as cancer cells and foreign things like splinters of wood, differentiating these from the organism's own healthy tissue in order to eliminate them.
An innate immunity is one that is typically inherited from one's parents and then passed on to their children. Because adaptive immunity is not something that can be passed down from parents to children, it cannot be inherited.

This study stresses the importance of lifestyle adaptations in primary as well as secondary prevention of non-communicable diseases. Which of the following are modifiable lifestyle behaviors that could impact health?
A. Reducing sodium Intake to 2400 miligrams per day
B. Uimiting intoke of monunsaturated fats.
C. Obtaining a minimum of 150 minutes of vigorous exercise daily
D. Aiming to eat at least 5 servings of fruits and vegetablos daily
The modifiable lifestyle that could have a more positive impact on health in the prevention of non-communicable diseases are:
A. Reducing sodium Intake to 2400 miligrams per day
B. Limiting intake of monunsaturated fats.
D. Aiming to eat at least 5 servings of fruits and vegetablos daily
Noncommunicable diseases are highly preventable and are mostly triggered by inadequate diet, sedentary lifestyle, consumption of high-calorie beverages, foods of low nutritional value, and high intake of tobacco and alcohol.
A. Reducing sodium Intake to 2400 miligrams per day
Consuming excess sodium can affect from the fluid balance to our metabolism and thus, lead to different diseases.
It can trigger arterial hypertension and associated cardiovascular problems due to its vasoconstrictive effect and on fluid retention.
The World Health Organization recommends not exceeding 2 grams of sodium per day or, what is the same, limiting the consumption of salt to a maximum of 5 grams daily.
B. Limiting intake of monunsaturated fats.
Among the many benefits of Monounsaturated fats we find:
1) Decreased cardiovascular risk
2) Improved insulin sensitivity
3) Reduction of inflammation
D. Aiming to eat at least 5 servings of fruits and vegetables daily
Consuming, on a regular basis, at least 5 servings of fruits and vegetables a day, constitutes one of the bases of healthy eating, providing the body with all kinds of valuable nutrients for the fulfillment of different processes.
Their consumption helps prevent various diseases as they are high in fiber, vitamins, minerals, water and antioxidant substances, do not contain cholesterol and provide few calories.
On the other hand, World Health Organization offers guidance on the intensity of the types of activities and exercises.
Adults should spend a minimum of 150 minutes a week engaging in moderate physical activities this stimulates the immune system.
Therefore, we can conclude that modifiable lifestyle have a direct impact on people's health in the prevention of non-communicable diseases and quality of life.

in the olfactory organs, the olfactory receptor cells are located within which type of epithelium
Answer:
In the apical layer of the pseudostratified ciliated columnar epithelium.
Explanation:
The sustentacular cells work as metabolic and material assistance for the olfactory epithelium. Analogous to neural glial cells, maintaining non-neural cells in the olfactory epithelium that are found in the apical zone of the pseudostratified ciliated columnar epithelium. The olfactory epithelium, located inside the nasal cavity, consists of olfactory receptor cells, which possess functional cilia expansions. The cilia trap odor molecules as they cross beyond the epithelial exterior. Data regarding the molecules are then forwarded from the receptors to the olfactory bulb in the brain. There exist two types of maintaining cells in the olfactory epithelium: sustentacular cells and microvillar cells.
