Answer:

The correct answer will be options-A, C and E

Explanation:

The amount of dissolved salt present in the water is calculated in the terms of the practical salinity unit or PSU or ppt.

The salinity of the inter-tidal zone lies between 20-25 ppt whereas the salinity of the ocean lies between the 33-35 ppt. The salinity of the coral reefs lies between the 30-40 ppt.

The stream is the freshwater source which contains very less amount of salt and the neritic zone is the zone of the ocean in which sunlight can easily reach which contains low salt concentration.

Thus, the selected options are the correct answer.

IgorC [24]

The correct answer is D. Vacuole

Explanation:

In cells, the vacuole is the organelle in which different substances or solutions are stored, this includes wastes, water, food, and even solids that the cell does not require because they are waste and therefore might contaminate the cell or substances the cell store to be used later. Due to this, the vacuole is a chamber that contains specialized membranes that allow certain substances to go in or out. Also, vacuoles can be found in plants, animals, fungi, among others although in organisms such as plants they are bigger. According to this, it is vacuoles the organelle that stores wastes, water or food.

Lorico [155]

Each hemoglobin contains four iron-containing heme groups and four polypeptide chains. Four oxygen molecules can bind each Hb molecule.

True, four hemoglobin chains will contain one heme group, which will bind exactly one oxygen molecule. Since hemoglobin contains four globin chains with four heme groups, four oxygen molecules can bind to one hemoglobin molecule.

<h3>What is hemoglobin ?</h3>

Blood-carrying protein hemoglobin (haemoglobin BrE) is derived from the Greek word haîma and the Latin term globus. (/hi-m-lo-bn, h-mo-/ abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein found in the tissues of some invertebrates as well as the red blood cells (erythrocytes) of practically all vertebrates (with the exception of the fish family Channichthyidae). The blood's hemoglobin transports oxygen from the respiratory system, including the lungs and gills, to the rest of the body (i.e. tissues). There, the oxygen is released, allowing aerobic respiration to take place and produce energy for an organism's metabolic processes. Every 100 mL of blood in a healthy person has 12 to 20 grams of hemoglobin.
