You have a basket of vegetables which contains carrot, potato, tomato, ginger, radish, sweet potato. Select two vegetables to represent the correct homologous structures.

Slides of binary fission in amoeba and budding in yeast were given for observations to a group of students. Some of the observations reported by the group are given below:

I. Cytokinesis was observed in the yeast cell.

II. A chain of buds were observed due to reproduction in amoeba.

III. Single cell of amoeba and single cell of yeast were undergoing binary fission and budding respectively.

IV. Elongated nucleus was dividing to form two daughter nuclei in amoeba.

The correctly reported observations are:

Study the different conclusions drawn by students on the basis of their observations of fresh available specimens of plants and animals:

I. Potato and sweet potato are homologous organs.

II. Wings of insects and wings of bird are analogous organs.

III. Wings of insects and wings of bats are homologous organs.

IV. Thorns of citrus and tendrils of Cucurbita are homologous organs.

The correct conclusions are:

Name two salts each of calcium and magnesium which make the water hard?

Name the process of asexual reproduction shown by yeast. What type of living being is yeast? What is its commercial importance?
