alleles of different genes tend to be connected together when does genes are on the same chromosome the Offspring received one recessive allele from each parents
Hope it helps
Answer:
No
Explanation:
Both A alleles and B alleles are dominant over the O alleles. This means that both parents must have an O allele present to even have a chance of having a child with type O blood. Lets say the mother has type O blood with the father having type AB blood. The possible combination would be: AO, BO, AO, BO. The punnett square should look like this:
A B
O AO BO
O AO BO
Chemical messengers and the Electrical signals are the two main methods by which cells communicate with each other to coordinate their functions and metabolic activities.
According to biologist, A cell communicates through chemical messengers, by sending the chemical signals to other cells and also receive that signal from another cell. Similarly, Electrical signals or impulses also work in the same way.
Therefore, body contains many types of lipids which works as a chemical messengers also electical signal or impulses can easily travel throught these lipids. Cell uses these chemical messengers and electrical impulses to communicate with other cell. Although, In order to trigger a response, these signals are transmitted across the cell membrane of the cell.

Answer:
The resistance of the device is 27Ω
Explanation:
When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.
In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.
Using Ohm's law
Ω
