Correct Answer: D. surface tension

Correct Answer: B. undercasting

Explanation

The errors that will affect the agreement of the trial balance are: one sided omission, two entries on the same side, undercasting or overcasting of balances etc.

Correct Answer: B. bring government nearer to the people

Correct Answer: C. Kg m\(^{2}\) s\(^{-2}\)

Explanation

Joule as the unit of work done or energy used.

Force = mass × acceleration

Work = Force × Distance

Work = mass x acceleration x distance

Joule = kg × \(\frac{m}{s^2}\) × m

→ kg m\(^2\) s\(^{-2}\)

Correct Answer: D. characters

Correct Answer: A) K and Na ions

Explanation

Neurons are cells in the nervous system responsible for transmitting information throughout the body. The question is asking which pair of ions is involved in the transmission of impulses by neurons. Impulses are electrical signals that are transmitted along neurons to communicate information. The correct answer is option A: K and Na ions. These two ions are involved in the process of action potential, which is the electrical signal that travels along a neuron. When an electrical signal reaches the end of a neuron, it triggers the release of neurotransmitters, which are chemicals that communicate with the next neuron in the pathway. K and Na ions are important in this process because they are responsible for the changes in electrical charge that occur in the neuron during transmission. When a neuron is at rest, the inside of the cell is negatively charged compared to the outside. When a signal is received, Na ions rush into the cell, causing it to become positively charged. This change in charge triggers the release of K ions, which then flow out of the cell to restore the negative charge. This process of ion flow creates the electrical signal that travels along the neuron. Option B, Na and Mg ions, are not involved in the transmission of impulses by neurons. Option C, K and Cl ions, are involved in the maintenance of the resting potential of a neuron but not in the transmission of impulses. Option D, K and Ca ions, are involved in the release of neurotransmitters but not in the transmission of impulses. In summary, K and Na ions are involved in the transmission of impulses by neurons, playing a crucial role in the action potential that allows information to be transmitted along neurons.

Dear Marvelous,

How are you and everybody over there. I hope school is going on well, it being so long that I have written to you. So, I am very sorry and thus ask for your forgiveness.

To start with, it is a great pleasure that I write to inform you about the prestigious house father built for us as family. The house is located around Lagos, close to Lekki. It was built around 25th of December 2016 and we moved into the house on the 23nd of april 2017. The colour of the house was painted Brown and Cream, which dad know that it is your favourite colour. The type of house that was built was duplex. It has five bedroom (2 down, 3 up ), including swimming pool. The house was so great that people was demanding for the plan of the house from the construction manager.

However the house has actually add prestige and respect to our family, yesterday father received a call from unknown person and was told to come and received a contract which was worth over ? 2 million. Also he had a call from the Ministry of Education to come and direct the contractor on how to built a day and boarding school in our area.

The community has also decided to give a chieftancy title to daddy because of the new status the new building has bestowed on our family, Due to the house we are now the new bride of the entire community, Even the school. I attended, the teaching and non-teaching staff plus my mates looked at me with a special attention and awareness.

Furthermore, the new house that father built has brought us respect and great favour in so many ways. Finally, brother I know and I pray that your holiday of this year will be filled with Joy due to what father has done for us. Extend my greetings to everybody over there, see you soon.

Yours Sincerely,

Sandra.

Correct Answer: D. 194

Correct Answer: D. homologous pairs separate and are pulled toward opposite poles of the cell

Explanation

There are no homologous pairs in mitosis. Mitosis has sister chromatids that separate and result in two identical daughter cells. Meiosis has homologous pairs because it occurs in sex cells and has one chromosome from the father and the other from the mother. These chromosomes pair up in Metaphase I and then separate in Anaphase I. Mitosis occurs in somatic cells so there is only one chromosome made up of two sister chromatids that separate during Anaphase.
