Answer:
Bacteria has 1 cell and An Animal has multiple cells.
Explanation:
Bacteria is a cell its self. While An Animal, It has multiple cells that create multiple tissues, and those tissues create multiple organs, those organs make up an organ system. After the Organ System, it's an organism.
Organism = Animal, Human, Ect.
Meanwhile, Bacteria is made up ONE CELL (bacteria it's self is 1 cell)
So the answer is "Bacteria has 1 cell and An Animal has multiple cells."

Explanation:
rice and rice coatssalt and sugarsand and mudwheat flour and corn flour32.5 g to fluid ounces
In your conversion from Milli- to Centi- units, would you move the decimal point to the left or the right?
Answer:
one unit to the left
Explanation:
cm are 10 times mm, so to convert you have to divide by ten
Examples
100 mm = 10,0 cm
0.50 mm = 0.05 cm

where did they start water conservation in tamil nadu . short answer
Explanation:
The 2019 water crisis in Chennai has made us realize the importance of saving water more than ever. Water, as we all know, is a finite resource without which our planet would be a barren wasteland. Today with our increasing population it would be logical to say that our water consumption has also increased. And with increasing demand and lesser supply, water scarcity arises. Our ancestors who had foreseen the potential dangers of water scarcity had developed methods to conserve water that was suited for the varied terrain of the Tamil-speaking kingdoms.
Traditional Rainwater Conservation methods of Tamil Nadu
Eri
There are no perennial rivers in Tamil Nadu except the Thamirabharani River which flows through Thirunelveli district. And so, several hundred years ago a simple system was devised to utilize the rainwater to the fullest. An Eri or tank system is one of the oldest forms of water conservation systems in India. Many Eris are still in use in Tamil Nadu and play an active role in irrigation. They act as water reservoirs and flood control systems. They prevent soil erosion, recharge groundwater, and prevent wastage of runoff water during heavy rainfall.
Kudimaramathu
Kudimaramathu is one of the old traditional practice of stakeholders participating in the maintenance and management of irrigation systems. During earlier days, citizens of a village used to actively participate in maintaining the water bodies of their village by deepening and widening the lakes and ponds and restoring the water bodies back to their original form. The silt, rich in nutrients, collected in the process would be used by the farmers themselves in their field. A sense of collective ownership ensured the continued survival of the water bodies.

Density and Years: What do you know?Objectives: determine and compare density of pennies to assess composition. Procedure:1. Read the directions and create a data table accordingly.2. Place 15-20 pennies in order of consecutive dates. Find the mass of each penny and record.3. Find the volume of all 5 pennies by water displacement and record in your data table. Record the volume adding 5 more pennies at a time until you have measured them all (15-20).a. Find the average volume of 1 penny.4. Calculate the density of each penny and graph according to the year.5. If the density of copper is 8.96 g/cm3 what would the mass of a pure copper penny be?6. Draw a conclusion.7. How might this relate to a real world example?

What is the difference between luminous objects and non luminous objects
Answer:
Objects that can emit light energy by themselves are known as luminous objects. Objects that cannot emit light energy by themselves are known as non-luminous objects.
Explanation:
Explanation:
Luminous objects:- The objects that can emit light energy by themselves are known as luminous objects.
Objects like the sun that give out or emit light of their own are luminous objects.
Other examples of luminous bodies are Electric bulb, torch etc.
Non-luminous objects:- the objects that can not emit light energy by themselves are known as Non- luminous objects.
Objects like the moon that do not give out or emit light of their own are Non- luminous objects.
Moon is an example of a non-luminous object as we can see the moon because it reflects light from the sun.
Other examples of Non luminous bodies are pen, pencil, chair, wood etc.
Luminosity – It is defined as the luminous intensity in a particular direction; or we can say it is the apparent brightness of an image.
The brightness of a star is defined as the total energy radiated in unit time. It is related to the surface area (A) and the effective temperature (TT) ( the temperature of a black body having the same radius as the star and radiating the same amount of energy per unit area in one second ) by a form of Stefan’s law, here is given by
⇒L=AσT4⇒L=AσT4
where
σ is the Stefan’s constant and L is the luminosity.
Note:
The laptop screen, mobile screen you are looking at right now is luminous but the page of your book is a non-luminous object, which is why you need a light on to read it.
