Answer:
carbon dioxide at normal atmospheric concentrations is limiting for the metabo- lism and growth of most land plants of the world. These plants share a comparable photosynthetic metabolic pathway, termed C3 photosynthesis. With an increase in CO2 there is an increase in photosynthesis and growth.
Explanation:
Answer:
The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

3.B !! Very popular to be known , dinosaurs extinct due to metroites collision !!
Answer: c.ovaries.
Explanation:
Gymnosperms and angiosperms are plants with seeds, where the great advantage present in both groups is the presence of pollen grain (which is the male gametophyte), which eliminates the need for water during reproduction.
In gymnosperms, the gametophyte grows in structures called strobiles or cones. The male gametophyte is released in the wind and, with lucky, landing in a female strobile and germinates. The female gametophyte develops within the strobile leaf, waiting for the pollen grain.
On the other hand, the most evolutionarily successful is the angiosperm group, the plants with flower and fruit. Flowers were decisive in animal pollination. The flower contains the eggs and can be grouped in inflorescences or solitary. The flowers have structures to attract pollinators, such as beautiful colored petals.
Answer:
Comparison between serine protease and aspartic protease
Both serine protease and aspartic protease are the hydrolytic enzymes play an important role in the digestion of protein molecules
Explanation:
Contrast betwwen serine protease and aspartate protease
Serine protaese contain serine amino acids in its active site or substrate binding site whereas Aspartic protease contain aspartic acid in its active site of substrate binding site.
Trypsin, chymotrypsin and elastase belongs to the family of serine protease Whereas pepsin,rennin belongs to the family of aspartic protease.
