Question

Tell me some contrasaptive methods of analogous and homologous with the defination of each series...

Answer 1

Condoms: One method is a creation of a mechanical barrier so that sperms does not reach the egg. Condoms on penis or similar covering can serve this purpose.

Hormonal method: Another category of contraceptive acts by changing the hormonal balance so that eggs are not released and fertilization cannot occur. These drugs commonly need to be taken as pills.

Copper-T: This small device is placed in the uterus to prevent pregnancy. It is T-shaped and coiled with copper wire of which copper-ions kills the sperms and hence, egg is not fertilized.

Surgical methods: Surgical methods can also be used to block the deferens in male and fallopian tube in females.

Answer 2

hey

here is answer

homologous series.

homologous series may be defined as follows

a group of organic compounds containing a particular functional group is termed as homologous series.

a member of. homologous series is called a homologue.

characteristics.

1. all the members of homologous series can be described by a common general formula

2. each member of homologous series differs from its higher and lower neighbouring members by common difference of -CH2

3. all the members of homologous series shows similar chemical properties.

4. physical properties in a homologous series show a regular variation with an increase in molecular mass

hope it helps

thanks
