Answer:

Double fertilization. (Ans. 5)

Explanation:

Double fertilization is a complex fertilization process occurs only in flowering plants known as angiosperm. In this process two male gametes or sperm cells fertilization occurs, first one is fertilized with the egg and form the zygote and second one is fuses with the 2 polar nuclei which cause the formation of endosperm.

In double fertilization, after the process of fertilization, the tissue of ovary forming the fruit and fertilized ovule of an ovary forming the seed.

Lady bird [3.3K]

Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

30. One cause of muscle soreness is

xenn [34]

Answer:

c. lactic acid fermentation

Explanation:

If we did alcoholic fermentation, working out would make us feel drunk, not sore. This is only done by yeasts (a type of fungus) and bacteria. Glycolysis is simply an anaerobic process that occurs with fermentation and also regular aerobic respiration. It doesn't cause any soreness on its own. The Krebs cycle is the second major part to cellular respiration; it produces 6 NADH's, 2 FADH2's, 4 CO2's and 2 ATP; it's not involved in creating any soreness, as cell respiration does not create soreness. That leaves lactic acid fermentation, which we, bacteria, yeasts, and other organisms do. This is what we do when we run out of ample oxygen while doing some strenuous activity. Glycolysis is done with it. Glycolysis, however, relies on NAD+ to create ATP we need to maintain the same level of activity, lactic acid is produced as it accepts the 2 electrons and [H+] NAD+ should accept.
