Answer: I think the atomic radius decreases.
Explanation: The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.
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

What kinds of things do the functional domains of proteins interact with
(at molecular level)?
Protein domains are evolutionarily conserved regions of the proteins that play different biological functions. These regions can interact with DNA, RNA, and proteins (protein-protein interactions).
In DNA binding proteins, protein domains interact with DNA in order to regulate transcription, replication, recombination, etc.DNA binding proteins such as transcription factors interact through amino acids localized in specific domains with the atoms exposed in the major groove of DNA. These atoms vary depending on the nucleotide that interacts with the transcription factor.Some of the most common motifs observed in protein domains that interact with DNA include, among others, the basic helix-loop-helix motif, leucine zipper motif, zink finger motif, etc.RNA-binding proteins (RBPs) are proteins having specific domains that interact with RNA to form ribonucleoproteins.In protein interactions, protein domains interact with each other.Learn more in:

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.
