Answer:
mosses or lichens, algae fungi
this organisms are knows as pioneer species because they are the first species present.
Answer:
B. Enzymes generally catalyze only very specific biochemical reactions.
E. Most enzymes are proteins composed of amino acids
F. The cells of both eukaryotes and prokaryotes all contain enzymes.
G. If the active site of an enzyme is altered, the enzyme is unable to catalyze the biochemical reaction.
Explanation:
Enzymes refers to substances that acts as a catalyst in living organisms. They regulate the rate at which chemical reactions proceed without being altered in the process. Enzymes regulate the biological process that occur within living organisms.
Enzymes catalyze all aspects of cell metabolism such as digestion of food, conservation and transformation of chemical energy and the construction of cellular macromolecules from smaller precursors.
Application of enzymes
1. Industrial application
2. Medical application
1. Enzymes can be used for industrial application such as beer brewing, wine fermentation, bread leavening.
2. Enzyme can also be applied in the medical aspects for killing disease-causing microorganisms, promoting wound healing, and diagnosing some diseases.
Answer:
Upon nutrient limitation, budding yeast will produce daughter cells less than 20% of the mother cell size. This asymmetric division may select for growth functions that are efficient over a larger range in cell sizes, such as exponential growth. In turn, efficient growth over a large size range lessens the pressure to have precise size control.
Explanation:
In wild-type cells growing in nitrogen-rich medium, the size threshold to enter mitosis is high, and the G1/S size control is cryptic because cell division produces daughter cells with a size greater than the minimum required to initiate S phase. In these conditions, G2 is long and G1 is short. However, the cell size threshold to enter mitosis is greatly reduced when wild-type cells are shifted to medium with a poor nitrogen source, such as minimal medium with proline, isoleucine, or phenylalanine. In these conditions, wild-type cells initiate mitosis at a reduced cell size, generating two daughter cells that are smaller than the critical size threshold required to progress through G1/S
Mitosis was used for growth and repair growth would be extremely rapid and repair would also be extremely rapid
<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>
