1) Birthrate. Because you need to accommodate for all the little humans on earth, whether that be housing or taxes and such. Plus we don’t want overcrowding in certain areas.
2) death rate. It’s important to look at the death rate of a population because it can show the condition quality of certain areas. If a place has a higher death rate or the rate increases too quickly, then that should signal that something is wrong.
Psoriasis is a skin disease that manifests itself in symptoms of varying severity. It is a chronic disease that can not be cured but can be alleviated by many treatments (like chemotherapy).
Photochemotherapy: also called P-UVA. It consists of the combination of UVA (a type of UV light) radiation after the local or oral administration of a psoralen that acts as a sensitizing photo. It is used alternately in patients for whom UVB (another type of UV) has no effect, as P-UVA is more effective and longer-lasting, but is associated with basiloma (basal cell carcinoma) and melanoma.
Irregular galaxy
A galaxy that has an unidentified shape is best classified as an irregular galaxy.
An irregular galaxy is a galaxy that has an undefined regular shape. These galaxies are composed of large amounts of young stars, gas, and dust.

Answer:
<h2>2)</h2>
Explanation:
given
In pea plants, flower color is determined by different genes,
allel P= purple;
allele p= red;
allele L= long;
allele l= round
P is dominant on p and L is dominant on l.
Parents are as given;
PpLl crossed with ppll
F1 generation are;
PpLl, Ppll, ppLl and ppll,
as given Purple, long ( PpLl)= 47;
Red, round ( rrll )= 47;
Purle, round ( Ppll )=3;
Red, long ( ppLl)= 3
Purple, long and Red, round each are 47 in number, their genotype are same as parental genotype, so genes P and L are close together on the same pair of homologous chromosomes.
