What is measured with an electric balance

In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly ha

Answer:

Total four genotypes and its frequency

SsWw – 4/16

ssWw- 4/16

Ssww - 4/16

ssww - 4/16

Phenotype –

SsWw – Heterozygous Spotted skin and heterozygous wooled hair

ssWw - Homozygous non-spotted skin and heterozygous wooled hair

Ssww - Heterozygous Spotted skin and Homozygous non -wooled hair

ssww - Homozygous non-spotted skin and Homozygous non -wooled hair

Explanation:

Given -

Allele for spotted skin is "S"

Allele for non-spotted skin is "s"

Allele for Wooly hair is "W"

Allele for non-wooly hair is "w"

Allele "S" is dominant over "s"

And Allele "W" is dominant over "w"

Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman

Genotype of heterozygous spotted, non-wooly man - Ssww

Genotype of heterozygous wooly-haired, non-spotted woman - ssWw

How can pollution reduce the rate of photosynthesis? Research work (60-90 words) unnecessarily,useless answers will be reported

Anna71 [15]

$\huge\mathcal\green{answer}$

Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.

Which three organs produce enzymes that digest proteins ?

11111nata11111 [884]

1. Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.

2. Pepsin, produced in the stomach.

3. Trypsin, produced in the pancreas.

I'm probably wrong. Sorry.
