The academic performance of students can be improved if parents are encouraged to supervise the work of their wards. Parents should choose to become involved in homework. They should be involved, believe their involvement will make a positive difference in their children's learning, and perceive that their involvement is invited, expected, and valued by school personnel. The parents need to be engaged in a wide range of activities in this effort, from establishment of basic structures for homework performance to more complex efforts focused on teaching for understanding and helping students develop effective learning strategies.

The greatest cause of failure of a new teacher is in the area of interpersonal relations. If the teacher is not able to develop a bond or relationship with the students, she will be rejected by the students and will face a lot of hardships.

According to the law of conservation of energy , energy can only be transformed from to form to another , it can neither be created nor destroyed . The total energy before and after the transformation always remains constant.

The correct option is A.
Current (I)= 0.20 A
Time(t)= 15 min

t= 15 × 60= 900 seconds
[1 minute= 60 seconds]

We know that,
I = Q/t

0.20 = Q/900
Q= 0.20 × 900
Q= 180 C
Hence, the amount of electric charge that flows through the circuit is 180 coulombs.
 

Independent variables are plotted along X-axis and Dependent variables are plotted along Y-axis. In the distance-time graph, time is independent and distance is a dependent variables. Y-axis is Distance

While introducing every concept to the students and important activities should be done to make students interesting and curious about the concept. The concept should be started in such a way that as it progresses further the students should be more involved to construct knowledge.
Key Points
Asking students to vote on which of the four given organs is most important and asking them to explain why would be the best hook activity to introduce the heart as:

• The heart is the most important organ of our body which pumps the blood to hold the body and runs the total circulatory system.
• The students would be given organs like kidneys, heart, liver, and pancreas.
• The students will be individually asked to select one of the organs from the four which they consider to be the most important organs of our body.
• Then each student will be asked to explain the reasons why he or she considers that particular organ to be the more important organ of our body than the other three.
• As the discussion progresses the important functions of the heart will be familiarized to the students and they automatically know the importance of the heart and are so interested to know more about it.

Hence asking students to vote on which of the four given organs is most important and asking them to explain why would be the best hook activity to introduce about heart.
Additional Information

• On the other hand asking the students to draw the shape of the heart, giving them chance to choose if they want to learn about the heart or kidney first, and showing students a movie clip with the heart rate on the monitor or not best hook activities to introduce the topic because in this the curiosity of students and knowledge construction will be less.

• a) In oxidation, oxygen is added to a substance: This is correct. Oxidation involves the addition of oxygen or the loss of electrons.

• b) In reduction, hydrogen is added to a substance: This is correct. Reduction typically involves the addition of hydrogen or the gain of electrons.

• c) Oxidizing agent is oxidized: This is incorrect. The oxidizing agent is actually reduced as it gains electrons during the reaction, thereby oxidising the other substance.

• d) Reducing agent is oxidized: This is correct. The reducing agent loses electrons (is oxidized) while it reduces the other substance by donating electrons.

Where does fertilisation take place?

• Fertilisation: The process in which a sperm cell fuses with an egg cell to form a zygote, which eventually develops into an embryo.


• Location: Fertilisation takes place in the Fallopian tube of the female reproductive system.

Explanation:

• The female reproductive system consists of several organs, including the uterus, vagina, fallopian tubes, and cervix.


• During sexual intercourse, sperm is deposited in the vagina.


• The sperm then travels through the cervix and enters the uterus.


• From the uterus, the sperm continues its journey through the Fallopian tube.


• If an egg is present in the Fallopian tube, fertilisation can occur.


• The sperm penetrates the egg, and their genetic material combines to form a zygote.


• The zygote then implants itself in the uterus, where it develops into an embryo.

Conclusion:

• Fertilisation takes place in the Fallopian tube of the female reproductive system.


• It is the process of sperm fusing with an egg to form a zygote.


• The zygote then develops into an embryo and implants itself in the uterus.
