Answer:
16
Explanation:
For a species with four pairs of chromosomes, 16 gametic combinations are possible.
This is calculated by using the formula 2n
A normal human has two pairs of chromosome which calculated by 2*2=4 to give the possible gametic combinations. However in the case of 4 pairs of chromosomes it is calculated by 2*2*2*2= 16 possible genetic combinations.
Vestigial structures don't hurt the living being. Nature chooses against just unsafe attributes. Structures that have no obvious capacity and have all the earmarks of being lingering parts from a past progenitor are called minimal structures. Cases of minimal structures incorporate the human informative supplement, the pelvic bone of a snake, and the wings of flightless flying creatures.
General Characteristics
Unicellular, absorptive-heterotrophic, photoautotrophic, or chemoautotrophic prokaryotes.
Only one set of genes, usually in a single-stranded loop.
Lack sexual reproduction.
Several chemical types of cell walls.
Lack organelles such as centrioles, eukaryotic flagella, cilia, mitochondria, and chloroplasts.
Some bacteria have a unique type of rotating flagellum.
Photoautotrophic species have chlorophyll, but not chloroplasts (which are organelles that are separated form the surrounding cytoplasm by their own membranes).
They used to group organisms by watching their physical characteristics. For example animals with spines are grouped into vertibrates and organisms without spine are grouped into invertebrates . They also group organisms based on habitatats ( where the organisms live) . For example marine animals live in water and terrestrial organisms live in land. They grouped organisms based on their feeding behaviour. For example producers produce their own food.
Enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.
<h3>What are enzyme inhibitors?</h3>
Enzyme inhibitors are substances which inhibit the catalytic activity of enzymes.
Enzyme inhibitors are classified into three:
- Competitive inhibitors - compete with substrate for enzyme binding site. They have no effect on Vmax but increases Km.
- Uncompetitive inhibitors- bind to the enzyme–substrate complex. They decrease both Vmax and Km.
- Non-competitive inhibitors- bind to another site on the enzyme. They have no effect on Km but Vmax is decreased.
Therefore, the enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.
