Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.

Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify

bixtya [17]

Answer: Exploitation, invasive species

If the government introduces laws prohibiting hunting, it would somewhat reduce the impact of exploitation would have on the biodiversity because hunting is mainly done for the purpose of fun or to derive valuables from animals like skin, horn, ivory, venome for selling them in the international market and making huge profit from them. Introduction of prohibition law on hunting will reduce killing and exploitation of animals for their valuables.

If laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect of invasive species would have on the seas. Invasive species are those living species which are arrive or immegrate to new locations in search of resources. These species compete with native species which results in decline of native species. This will result in disturbance in actual sea biodiversity as this will result in decline in native sea species and may also lead to extinction of native species.

Alika [10]

Answer:

Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor

Explanation:

When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
