Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.)
Since it has a 4 protons and 5 neutrons, it has a mass number of 9.
Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions
Answer:
Polygenic.
Explanation:
A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes".
The correct answer is controlled braking.
If someone suddenly pulls out in front of the person while driving, the natural reaction is to apply the brakes. Although, this is a good reaction if there is the adequate distance to stop and one applies the brakes accurately.
While in case of emergency stops, one should apply brakes in a way, which will maintain the vehicle in a straight line and permits one to turn if it becomes essential. For this, the person can use stab braking method of controlled braking.
In controlled braking, one applies the brakes as hard as one can without locking the wheels. There is a need to keep steering wheel movements very slight while attempting this. If one needs to make bigger steering amendments or if the wheels lock, release the brakes.
Answer:
Blue offspring only
Explanation:
If A blue budgie is crossed with a white budgie.
i.e yyBB or yyBb × yybb
let use yyBb for blue budgie,so we have; yB, yb, yB, yb representing the columns on the horizontal rows of the punnet square.
on the other hand, in white budgie yybb, we will have yb, yb, yb, yb representing the rows on the vertical column of the punnet square.
if a dihybrid cross occurs among these representative, all progeny in the punnet square will be yyBb, showing that they are all Blue offspring only.
