Answer:Hummingbirds have long, needlelike beaks they use to probe deep into flowers. The hummingbird's beak is just a protective sheath for its tongue, which is actually what the hummingbird is using to get the nectar out of the flower. The tip of their tongue is forked and has little hairs all over it.
Explanation:
An adaptation is a physical or behavioral feature that helps an animal stay alive.
1. An adaptation an animal needs to meet the need for food: Sharp teeth.
An adaptation to meet the need for water: A tongue.
An adaptation for shelter: Sharp claws to climb trees for shelter.
3. Starts storing more fat, bears a warmer coat, and sleeps for hibernation.
5. If it's cold outside, fur can help keep an animal warm. A chameleon uses his skin (or covering) to blend into this surroundings.
6. "A". Sharp eyesight.

Answer:
Three halogens:
Fluorine, chlorine, bromine.
Explanation:
Halogens are present in group seventeen of periodic table.
Their are five elements in this group fluorine, chlorine, bromine, iodine, astatine.
Three halogens:
Fluorine, chlorine, bromine.
All these share common properties such as,
All of these have seven valance electrons.
When combine with hydrogen they form acids.
H₂ + Cl₂ → 2HCl
All of these are toxic in nature.
They are highly electronegative and most reactive elements.
When combine with metals they form salts such as sodium chloride, magnesium bromide.
2Na + Cl₂ → 2NaCl
2Na + Br₂ → 2NaBr
Mg + Br₂ → MgBr₂
Mg + Cl₂ → MgCl₂
Answer:
The total number of atoms when glucose and oxygen reacts stays the same when carbondioxide and water are produced.
Explanation:
Chemical reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
We can see that the number of atoms of each element remain same on both side of reaction so law of conservation of mass is followed by this reaction. Six number of carbon atoms twelve number of hydrogen atoms and eighteen number of oxygen atoms are present on both side.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
