Should girls cook during menstrual days or not? Why? plz tell me fast​
Len [333]

Answer:

IN OLDEN TIMES:

A girl, when she reaches puberty is barred from entering the prayer room or performing any religious prayers during her menstruation. The only reason mentioned in our scriptures is that she is (ashudha) unclean during that period.

During ancient days, women would take bath in the river, pond or near the well. During the time when the girl would be menstruating, it would be awkward to bathe outside in the river as it would probably ‘pollute’ the water.

So, the ladies did not take bath. Since the ladies did not take bath, they were naturally termed ‘unclean’ during that time. Hence, their being barred from the clean’ places in the house, namely the prayer room or the kitchen.

However, Science has a different meaning for the menstruation. As per science, a woman is more irritable during those days because of a hormonal imbalance. Psychics claim that there is a different aura around a menstruating woman, maybe again a chemical reaction.

Segregating to pray requires a positive attitude and people tend to respond to the negative virations of a person standing with you; maybe that was the reason why a woman was barred from public places and the kitchen.

TODAY:

Times have changed,

It is the old saying of old people. But of a girl cooks during periods then it is not to become bad in taste or it won't get spoiled. The taste of food is going to be same as she cooks on other days. So I think this saying is wrong and girls can cook during their mensuratl days. It is a natural cycle and they r not responsible for it

Tratando-se sobre atividades aeróbias, segundo Cooper (1972), qual das alternativas abaixo não está correta? a) Aumento da efici
olya-2409 [2.1K]

Answer:

Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)

Explanation.

Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.

Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.

En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.

Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.

Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.

This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.

Basically, exercise boosts the  HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.

Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.

Therefore, when calculated per week this would be an average of  20 minutes of exercise per day.

Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.

With the assumption that schmid-type metaphyseal chondrodysplasia is rare, is this type of dwarfism inherited as a dominant or r
Marrrta [24]

Answer and explanation;

-The nearly one-to-one ratio seen in the offspring suggests it is likely inherited as a dominant trait, with the dwarf parent being heterozygous for the dwarf allele along with the normal parent being homozygous for the normal allele.

-Metaphyseal chondrodysplasia, Schmid type (MCDS) is a type of skeletal disorder in which there is abnormal bone formation at the end of the long bones (metaphyses).  MCDS is caused by a mutation in one of the collagen genes. The MCDS mutation is passed on in an autosomal dominant manner.
