How does reproduction take place in yeast

Posted by Bharat Kumar Raj 7 years, 9 months ago

CBSE > Class 07 > Science

Amar Kumar 7 years, 9 months ago

Budding in Yeast: Yeast are unicellular (some are multicellular) eukaryotic micro-organisms belonging to the kingdom fungi. Most yeasts reproduce asexually by an asymmetric division process called budding. First it produces a small protuberance on the parent cell that grows to a full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell. The bud detaches from the mother’s body by forming a constriction at the base. Budding will repeat to form a chain of bud cells. The daughter cell produced during the budding process is generally smaller than the mother cell.

What is Mean by plasma

CBSE > Class 07 > Science

2 answers

Amar Kumar 7 years, 9 months ago

Plasma is a form of matter in which many of the electrons wander around freely among the nuclei of the atoms. Plasma has been called the fourth state of matter, the other three being solid, liquid and gas. Normally, the electrons in a solid, liquid, or gaseous sample of matter stay with the same atomic nucleus.

Plasma is the colorless liquid part of blood. Plasma holds blood cells but is not made from them. Plasma, a crucial part of blood, can be donated for use in medical procedures, either from plasma donation or as part of a regular blood donation.

How we can make electromagnrt?

Posted by Anjali Deshmukh 7 years, 9 months ago

CBSE > Class 07 > Science

1 answers

Amar Kumar 7 years, 9 months ago

Wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism. Use a pair of wire strippers to remove a few centimeters of insulation from each end of the wire. Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Make certain that you leave enough of the wire unwound so that you can attach the battery.

How do plants respire

Posted by Hrishika Raj 7 years, 9 months ago

CBSE > Class 07 > Science

1 answers

Kritika Trehan 7 years, 9 months ago

Plants respire through stomata present in leaves..photosynthesis and respiration both are different.
During respiration in plants, very little transport of gases takes place from one plant part to another. Therefore, each plant part takes care of its own energy needs, or in other words, its gas exchange need. Roots, stems and leaves of plants exchange gases for respiration separately. We already know, leaves of plants have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by the cells in the leaves to break down glucose into carbon dioxide and water.

Describe the events that lead to the formation of a cyclone.

Posted by ? Sr Kaur ? 7 years, 9 months ago

CBSE > Class 07 > Science

1 answers

Kritika Trehan 7 years, 9 months ago

Cyclone refers to any spinning storm that rotates around a low-pressure center. The low-pressure center is also referred to as the 'eye' of the storm, which is well known for being eerily calm compared with the areas under the spinning 'arms' of the storm. You could say that the eye is watching what's going on down below, so it needs a clear path, but the arms are where all the action happens because this is where the storm is throwing out all of its rain and wind.

Even though they form over different areas, cyclones tend to come about in the same way and revolve around that low-pressure eye. Warm air likes to rise, and as it rises, it cools. Cool air can't hold as much moisture as warm air, so that water gets squeezed out of the condensing air and a cloud begins to form. If the warm air rises very quickly, this creates an updraft.

Likewise, if the water in the cloud builds up enough, it may fall back to the ground as rain and draw cool air down with it as a downdraft. When they work together, that warm updraft and cool downdraft create a storm cell. As this process continues, the cloud grows and we eventually get a large thunderstorm cloud.

This thunderstorm cloud is now ready to diversify into other storms like tropical cyclones and tornadoes. But this can't happen unless the air in the cloud starts spinning horizontally. If this occurs over the tropical ocean, this is called a tropical depression. This is like a baby tropical cyclone, with wind speeds less than 39 mph.

If it starts spinning even faster and has wind speeds between 40-73 mph, we have a tropical storm. If the storm grows even larger over the tropical ocean and has wind speeds above 74 mph, we have our full-grown hurricane, typhoon or cyclone, depending on where that storm is found.
