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.

If the seawater carbonate ion concentration is 250 µmol/kg, a) what is the approximate rate of calcification, and b) approximately how many days would it take 1 square meter of reef to accumulate 30 mmol of calcium carbonate?
a) The approximate rate of calcification = 10 mmol CaCO₃ per m² per day
b) The approximate number of days for 1 m² of reef to accumulate 30 mmol = 0.3 days
a) Determine approximate rate of calcification
making use of the calcification rate map attached when the seawater carbonate ion concentration = 250 µmol/kg the rate of calcification = 10mmol CaCO₃ per day
b) determine number of days
using the relation below
Amount accumulated = Area * rate of calcification * time taken
where amount = 30 mmol
rate = 10 mmol
Area = 1 m²
time = ?
∴ Time = amount / ( Area * rate )
= 30 / ( 10 * 10 )
= 0.3 days

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.
