Answer:
Doppler Red-Shift Evidence
Explanation:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
The arteries carry blood away from the heart
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
Yes because if the water gets too high it will fill the reservoirs before it gets to land so its true
Air passes from the trachea into the lungs through two large tubes called : Bronchi
Bronchi has the function to conducts air to the lungs (it somehow acts as an airway to the respiratory system)
hope this helps
