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.
Answer: Plant vegetation so that their roots hold the soil firmly.
Build walls around the farm area.
Add natural fertilizers to the soil.
Soil erosion is a process of removal of top layer of soil which get sediment at some other place due to the affect of agents like wind and water. The superficial upper layers of soil are rich source of nutrients and organic matter and active region for germination of seeds and plant growth. Soil erosion removes these superficial layers making soil less fertile or not fertile and less useful for plant growth.
Plants growing in a vegetation have roots which can hold the soil and will prevent soil erosion from wind and water or any other agent. Building of walls around the farm area will prevent flood water to get inside the farm area and hence, prevents soil erosion by water. Addition of natural fertilizers to the soil adds up nutrients to the soil which facilitate plant growth and plant roots hold the soil therefore, prevents soil erosion.
Plants have cell wall, large vacuole, chloroplasts, flagella only in gamets,
animal cell has , no cell wall, small or no vacuole, no chloroplasts, flagella
Answer:
BBBB = 0.64
BBBG = 0.20
BGBG = 0.16
Explanation:
Genotype frequency = individuals of that particular genotype / total number of individuals
Genotype frequency of blue geckos (BBBB) = 160 / ( 160 + 50 + 40 ) = 160/250 = 0.64
Genotype frequency of turquoise geckos (BBBG) = 50/250 = 0.20
Genotype frequency of green geckos (BGBG) = 40/250 = 0.16
Answer: A
Explanation:
Exponential growth simply means a rapid increase in size and a constant growing rate
