Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.
iii) Fragile teeth.
iv) Stiff joints.
Answer:
Specie
Explanation:
They are a group that interbreed with each other, only, since they cannot produce fertile offspring with those of another species.
Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.
In a study, competition among plants
are normal. Hence, all plants required a few basic elements like the light,
water, nitrogen, or phosphorus, depending upon the species and the location. Evidence
that can conclude that competition do really happen in plants is that some plants
release toxins into the soil, in their dropped leaves which wipe out the competition
for soil nutrients (such as weeds). And when it come an area with many trees in
close proximity such as a forest, height is also indicative of competition for
light.
