Answer: Internal fertilization
Explanation: Most birds and reptiles undergoes internal fertilization in which the sperm cells are ejected and fertilizes the egg cell inside the body of the animal.
I’m pretty sure it would be:
NH4+Cn
The density of the wood : 1.45 g/cm³
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
![\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}](https://tex.z-dn.net/?f=%5Clarge%20%7B%5Cboxed%20%7B%5Cbold%20%7B%5Crho%20~%20%3D%20~%20%5Cfrac%20%7Bm%7D%20%7BV%7D%7D%7D%7D)
ρ = density
m = mass
v = volume

Answer:
less reactive less potential
Explanation:
The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.
The angle that exists among two covalent bonds that come from the same atom is known as a bond angle.
When there have four bonds and no lone pairs, the tetrahedral geometry occurs. Given that many molecules would adopt this geometry, it represents one of the most significant and prevalent geometries. For example,
assumes a tetrahedral geometry. Tetrahedral molecules have a bond angle of around 109.5°.
Therefore, The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.
