1)Turn off faucets. Start saving by breaking a bad habit: Never let faucet water run needlessly as you wash or rinse dishes, wash your hands or face, brush your teeth or shave. --------------------------------------------------- 2.( Use every drop. Learn to repurpose water. One easy way is to capture under your colander the potable water you use to rinse fruits and veggies, and deposit it in the garden. Do the same while you wait for your hot water to come in. -------------------------------------------------------------- 3) Fix all the leaks in your home . Leaks can lead to a lot of wastage of water. -------------------------------------------- 4)Use Water harvesting methods. Mainly, Rainwater harvesting, is a cheap and effective way to save water. ----------------------------- 5)use for your need, not for greed

How are summer monsoons caused over India? How are they useful?

Posted by Harshitha R 6 years, 2 months ago

CBSE > Class 07 > Science

1 answers

Sia ? 6 years, 2 months ago

Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. The summer monsoon is associated with heavy rainfall. The summer monsoon brings a humid climate and torrential rainfall to these areas. The seasonal rains make it possible for agriculture, forests and inhabitants of the region to store water for the next dry cycle of the climate. The monsoon season also brings lower temperatures to the Southwest.

.. ... 6 years, 2 months ago

Summer monsoons are associated with heavy rainfall.[3] As winter ends, warm winds from the southwestern Indian Ocean flow up towards Southern Asia bringing with it humid climate and intense rainfall. This hot air is caused by the intense radiant heat received from the Sun during its solar maximum in late spring which results in uneven heating of the Earth, and therefore increased winds.[5]

1 answers

.. ... 6 years, 2 months ago

A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transaction (e.g., text message) that passes through that facility or device.---------------------------------- For telephone service providers, they are critical to the production of revenue, in that they provide the basis for the generation of telephone bills. For law enforcement, call detail records provide a wealth of information that can help to identify suspects, in that they can reveal details as to an individual's relationships with associates, communication and behavior patterns, and even location data that can establish the whereabouts of an individual during the entirety of the call. For companies with PBX telephone systems, call detail records provide a means of tracking long-distance access, can monitor telephone usage by department or office, and can create listing of incoming and outgoing calls.

How do reproduction done in human in especially boys and girls

Posted by Surya Basuri 6 years, 2 months ago

Meghna Thapar 5 years, 9 months ago

Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father.
