Answer:
The correct option is <em>C. A gene is a specific segment of DNA on a chromosome</em>
Explanation:
Option A is false because a gene is a segment on a chromosome.
Option B is false because a chromosome carries many genes.
Option D is false because a gene carries a segment of DNA, not all of the DNA.
Option C is correct because there are many genes present on a single chromosome. Each gene carries a segment of DNA. The position of a gene on the chromosome is known as its loci.
Answer: Option C
6CO2 + 12H2O + light --> C6H12O6 + 6O2 + 6H2O
Explanation:
Photosynthesis is the process by which autotrophs such as green plants generate their food (usually sugar molecules) from simple inorganic molecules like atmospheric carbon dioxide and water, in the presence of sunlight trapped by chlorophyll.
From the equation of photosynthesis,
- several units of glucose molecules (C6H12O6) is produced and then stored in plants tissues as starch.
- Oxygen is released as by-product
- Some water is given off also
Answer:
The correct answer will be option- leukocyte.
Explanation:
The granulocytes are the cells which contain secretory granules in its cytoplasm. The granulocytes are a part of the white blood cells or "leukocytes" which provide immunity to the organism.
The granulocytes are of three types called mainly the neutrophil, basophil, or eosinophil which provide immunity by ingesting the foreign material and digest the invading microbes by the action of enzymes produced by the granules in the cytoplasm.
Thus, option- leukocyte is the correct answer.
Frogs exchange gases through their skin and the lining of their mouths. This exchange of gases is referred to as respiration. During the larval stage in frogs development, it lacks functional lungs but they can take in oxygen through gills which are in process of metamorphosis.
The gills take in oxygen when water is being passed over them. Once lungs are mature, they lose their gills and are able to bring in oxygen through lungs.
They rely on lungs to breath when they are active and they need more oxygen than what skin respiration alone can provide.
Although they have oxygen, most of their respiration occurs through the skin.
