Answer:
Spoils system
Explanation:
In politics and government, a spoils system is a practice in which a political party, after winning an election, gives government jobs to its supporters, friends, and relatives as a reward for working toward victory, and as an incentive to keep working for the party—as opposed to a merit system, where offices are awarded on the basis of some measure of merit, independent of political activity.
The patronage system is the appointment or hiring of a person to a government post on the basis of partisan loyalty.
Elected officials at the national, state, and local levels of government use such appointments to reward the people who help them win and maintain an office.
What was the purpose of the patron system?
Patrons protected individual clients from the tax collector and other public obligations. In return, clients gave them money or services. Some clients even surrendered ownership of their land to their patron
What was the benefit of having a patron?
A Patron is someone who provides some sort of benefit to your organization through their association with your group. They are usually someone who has a high profile in some way, and through their position can help raise the profile of your organization as well.

the denaturation temperature of rubisco in a certain plant was determined to be 76.2 degrees celsius. what happens to the rate of photosynthesis if the temperature continues to increase?
If the temperature continues to increase the rate of photosynthesis would decrease.
Enzyme-specific processes include photosynthesis. There is a temperature range (25–35 °C) where all enzymes function best. The rate of photosynthesis declines as a result of the denaturation of enzymes brought on by rising temperatures. Photosynthesis speed is influenced by temperature. With an increase in temperature, photosynthesis occurs more quickly. Over 40 °C slows down photosynthesis, which is a natural process.
This is the case because the process is governed by enzymes. As a result, the rate of photosynthesis will decrease at temperatures over 35°C because the carbon-fixing enzymes will have become denaturized. The rate of respiration also decreases dramatically at very high temperatures.

Penguins are a group of waterfowl that cannot fly. They remain almost entirely in the Southern Hemisphere.
The most effective species, the Galapagos penguin, lives north of the equator. Penguins are highly adapted to an aquatic lifestyle and have contrasting black and white plumage and flippers for swimming. Tall penguins feed on krill, fish, squid and other types of marine life, confiscating them for payment and even swallowing them whole as they swim. Penguins have barbed tongues and jaws that are effective for gripping slippery prey.

What is co-dominance with an example?Co-dominance is a form of inheritance in which alleles of a pair of genes are fully expressed in heterozygotes. As a result, the child's phenotype is a combination of the parent's phenotypes. Hence, the trait possess neither dominance nor recessive. In genetics terms, codominance refers to a pattern of inheritance in which two versions (alleles) of the same gene are expressed separately to produce different traits in an individual.If a person has both her IA and IB antigens on his surface, that person's blood type is his AB. In human, the AB blood type is an illustration of codominance. In blood group AB, phenotypic effects of both IA and IB alleles are observed.What is the difference between dominant and codominant?In perfect dominance, only one allele of the genotype is present in the phenotype.
