Question

which of the following has highest electronegativity​

Answer 1

Answer:

All children will inherit an X chromosome from their mother regardless

of whether they are boys or girls. Thus, the sex of the children will be

determined by what they inherit from their father. A child who inherits

an X chromosome from her father will be a girl, and one who inherits a

Y chromosome from him will be a boy.

28 Use of Plastic cups raised the concern towards hygiene thus they were

replaced by disposable plastic cups.

Plastic cups are non-biodegradable and harm the environment friendly.

They were thus replaced by Kulhads.

Making Kulhad made of clay on a large scale resulted in the loss of top

fertile soil.

Now, disposable paper cups are used because - the paper can be

recycled, it is biodegradable and is eco-friendly material which does not

cause environmental pollution.

- Passes through glomerulus in the Bowman's capsule - Ultra

filtration

- Filtrate initially has glucose, amino acids, water, salts and

nitrogenous waste

- Reabsorption – Water (as per the need of the body), Glucose and

amino acids are all reabsorbed –

- Secretion of excess water, salts and urea (nitrogenous waste)

which makes up the urine
