The correct answer is option C, that is, both the organisms generate haploid spores and exhibit diploid and haploid stages.
The sporophyte (of the haploid stage) in pteridophytes produce spores. The diploid stage in pteridophytes may take place when two of the spores combines and give rise to a prothallus, that is, the diploid stage of the pteridophytes.
In fungi, the production of spores takes place by sporangiophores (haploid stage). At a certain stage, two horizontal hyphae among the two species of fungi, may amalgamate at the tips and produce a zygote (diploid) via plasmogamy and karyogamy.
The answer is carbon dioxide, methane, and other gases; infrared. The greenhouse effect is the procedure by which radiation from a planet's environment warms the planet's surface to a temperature above what it would be without its air. Earth's regular greenhouse effect is basic to supporting life. Human exercises, primarily the consumption of non-renewable energy sources and clearing of backwoods, have fortified the nursery impact and caused a dangerous atmospheric division.
The phosphorylation of fructose 6-phosphate to fructose-1,6-bisphosphate is the committed step in glycolysis because<u> fructose 1,6-bisphosphate can undergo no other reactions than those of glycolysis.</u>
<h3>
What is phosphorylation?</h3>
- The crucial process of glycolysis involves the breakdown of glucose into two molecules of pyruvate. It involves a number of steps and many enzymes.
- It takes place over the course of ten phases, demonstrating how important and crucial phosphorylation is to the production of the final goods. Step 1 of the preliminary step (first half of glycolysis) and step 6 of the payout phase reactions are started by phosphorylation (second phase of glycolysis).
- Because fructose-6-phosphate cannot cross the cell membrane, it is forced to remain inside the cell. Step 3 involves phosphorylation, when fructose-6-phosphate is changed into fructose-1,6-bisphosphate.

Answer:
Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.
Explanation:
Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
