Answer:
The water vascular system of echinoderms functions in locomotion and feeding.
Explanation:
The water vascular system of echinoderms is responsible for the functions in locomotion and feeding. The water vascular system is a hydraulic system that is used by echinoderms for example sea stars and sea urchins, for the purpose of locomotion (movement), food and waste transportation, and respiration. This system is composed of canals connecting numerous tube feet.
Answer: The bubbles will form due to the liberation of oxygen gas and white spots will develop on the liver.
Explanation:
The liver is a vital organ, its function is to metabolize the toxins into less harmful metabolites, that are excreted out of the body.
The catalase is one of the enzymes that participate in the metabolic activities of the liver. In the given condition, when hydrogen peroxide and liver were combined. The catalase enzyme breaks down the hydrogen peroxide into water and oxygen. In this reaction, the oxygen gas is liberated, in the form of bubbles and this reaction produces white colored foam which later leaves white spots on the liver.
Answer:
Explanation:
1- Capping occurs at the 5' end of mRNA.
2- The nucleside added is 7-methylguanosine.
3- The nuceloside is connected to the mRNA through a 5′ to 5′ triphosphate linkage.
4- The added nuceloside is modified by methylation at the nitrogen atom.
5- The mRNA is modified by methylation of ribose residues at the 2'-hydroxy position.

Answer:</h2>
Generally, <u>D) non-metals are gases</u> which are at room temperature.
<h2>
Explanation:</h2>
Those metals which lack the property of the metal are called as non-metal. Usually they are characterized by the following features:
- Nonmetals don't conduct electricity through them.
- Nonmetals don't allow heat to pass through them.
- They don't show ductility and malleability.
- The nonmetals not only include gases but there are some solids which do not exhibit the above mentioned characters are also nonmetals. Some of the solid nonmetals includes graphite, carbon, wood, and so on.
Thus, from the above data, it can be inferred that option D which states that gases at room temperature is considered as most suitable answer for non-metals, as option A, B, and C are characteristic of metals.
