Correct Answer: C. II< III< I

Explanation

Alpha particles are highly ionising because of their double positive charge, large mass (compared to a beta particle) and because they are relatively slow. They can cause multiple ionisations within a very small distance. And the gamma radiation has the least ionising power.

Correct Answer: D) Barnabas and Matthias

Explanation

This question is asking about the two men who were nominated by the Apostles to replace Judas Iscariot. Judas Iscariot was one of the twelve disciples of Jesus Christ who betrayed him and later committed suicide.

The correct answer to this question is Option D: Barnabas and Matthias. The Apostles nominated these two men to replace Judas Iscariot as one of the twelve disciples.

Barnabas was a prominent member of the early Christian church, known for his generosity and encouragement of new converts. He was also a close associate of the Apostle Paul. Matthias, on the other hand, was chosen by the Apostles to replace Judas Iscariot based on the criteria that he must have been a witness of Jesus' resurrection.

It is important to note that the Bible does not provide much information about Matthias, and some scholars believe that he may have been a lesser-known figure compared to other disciples.

In conclusion, the two men nominated by the Apostles to replace Judas Iscariot were Barnabas and Matthias, as stated in Option D.

Correct Answer: B) chemotaxis

Explanation

An amoeba is a tiny, single-celled organism that moves by extending and retracting its pseudopodia or false feet. The question is asking what the movement of an amoeba towards a crumb of cake in a pond is called. The answer is Option B, chemotaxis. Chemotaxis is the movement of an organism in response to a chemical stimulus. In this case, the chemical stimulus is the scent of the cake crumb that the amoeba is moving towards. The amoeba detects the scent using its sense of smell and moves towards the source of the scent. Phototropism (Option A) is a different type of movement where an organism moves towards or away from light. Thermotaxis (Option C) is movement in response to temperature changes, and nastic movement (Option D) refers to non-directional movement in response to a stimulus, usually involving changes in turgor pressure. It is important to note that amoebas do not have a sense of smell in the way that humans or other animals do. Instead, they are able to detect chemicals in their environment using specialized receptors on their cell surface. Overall, the movement of the amoeba towards the cake crumb is an example of chemotaxis, where the organism is moving in response to a chemical stimulus.
