What happens when you draw in or exhale air?
VikaD [51]
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale<span />

The embryos of a bird, a reptile, and a mammal are similar in appearance. How does comparing the physical appearance of embryos
Blababa [14]

Answer:

I believe the answer is A.

Explanation:

Species may share similar physical features because that feature was present in a common ancestor. These features are known as homologous structures.

Answers b, c, and d sound probable, but those responses of foods, habitat, and genetic mutation don't directly correlate with the theory of evolution.

For example: In option d, these organisms all most likely suffered from a genetic mutation, but the similarity of the embryos does not prove that.

from 150 gram of Urea 3 into 10 power 23 molecules are removed then how many molecules are remain....​
Vikki [24]

Answer:

Amount remaining = 1.205 * 10²⁴ molecules of urea

Explanation:

The molecular formula of urea is CH₄N₂O. It has a molar mass of 60 g/mol.

Number of moles of urea present in 150 g of urea = mass/molar mass

Number of moles = 150 g/ 60 g/mol = 2.5 moles of urea

I mole of urea contains 6.02 * 10²³ molecules of urea

2.5 moles of urea will contain 2.5 * 6.02 * 10²³ molecules of urea = 1.505 * 10²⁴ molecules of urea

If 3 * 10²³ molecules are removed from 1.505 * 10²⁴ molecules of urea, amount remaining will be:

1.05 * 10²⁴ - 3 * 10²³ = (15.05 - 3) * 10²³ molecules of urea

Amount remaining = 12.05 * 10²³

Amount remaining = 1.205 * 10²⁴ molecules of urea
