Chimpanzees.

Explanation:

Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom

Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. So, chimpanzees are similar to humans.

What animals are similar in form to humans?

Humans, chimpanzees, gorillas, orangutans, and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.

Why humans are also animals?

Humans can move on their own and are placed in the animal kingdom. Further, humans belong to the animal phylum known as chordates because we have a backbone. The human animal has hair and milk glands, so we are placed in the class of mammals. Within the mammal class, humans are placed in the primate order.

Thus, chimpanzees are similar to humans.

The acronym for the characteristics of life is REACHNGRO.

What is REACHNGRO?

REACHNGRO is the acronym used for the characteristics of life.

As we know, characteristics of life are certain traits that help distinguish between living things and non living things. Sometimes, non living things attribute certain traits as living things do. We know that a car moves, but so does a cat or a dog. A cloud grows in size, but so do plants and trees. So a way to distinguish between living and non living things is these characteristics of life.

REACHNGRO stands for :

• R- reproduce

• E- energy

• A- adapt

• C- cells

• H- homeostasis

• N- nucleic acids

• G- growth/ development

• R- response to surroundings

• O- organizations

Less than and equal to the optimum temperature, any increase in the reaction temperature leads to a decrease in its rate is not true regarding enzymatic reactions.

Factors affecting enzyme

The reaction that enzymes catalyse receives activation energy from them.

Temperature is one of the elements impacting enzymes. Substrate molecules start to move more quickly as the temperature rises. By increasing the number of substrate molecules that come into contact with the enzymes' active sites, more substrate can bind.

The enzyme's active sites must be free for the velocity to be at its highest level.

The human body uses enzymes to accelerate chemical reactions. Among many other functions, they are crucial for respiration, food digestion, muscle, and neuron activity. There are thousands of enzymes in each cell of the human body. Each cell's use of enzymes aids in facilitating chemical reactions

Occurrence of endemic species in South America and Australia is due to continental drift. Continental drift is the gradual movement of the continents across the earth's surface.

Darwinism claims that the fossilized remains of South American species are similar to those found in Africa and Australia.

Thousands of animals and plants were gathered and described by Darwin during the Beagle's trip (1831–1836). He studied how species in South America adapted to a range of environments, including rainforest, grassland, and mountain ecosystems. The species in the temperate areas resembled the species of South America's tropical regions more than they did the similar species of Europe's temperate regions. For instance, although there are no rabbits in Argentina's grasslands, there are rodents that resemble them. These rodents are not linked to European rabbits, but rather to other rodents found in South America.

Answer:

The enzyme needed is topoisomerase. Topoisomerases are enzymes whose function is to regulate the unwinding of the DNA double helix. They ensure there is no over winding or underwinding of the helix. During the replication and transcription of DNA, the double helix becomes overwound ahead of the replication fork. If left to go on, the tension created would eventually hinder the ability of DNA and RNA polymerase enzymes to continue down the strand of DNA. Topoimerases I and II enzymes correct this, ensuring the polymerase enzymes do their work smoothly.

Histones are identical copies of the chromatin that cohesin holds in place at the centromere.

A histone is indeed a protein that gives chromosomes structural support. The lengthy DNA molecules that make up each chromosome must fit inside the cell nucleus. The chromosome takes on a more compact shape as a result of the DNA wrapping around complexes containing histone proteins.

DNA is shielded against tangle formation and damage by histones. Additionally, histones are crucial for DNA replication and gene control. Chromosomes' unraveled DNA would be exceedingly lengthy without histones.

when using the hill equation, it is possible to observe negative cooperativity.

Negative cooperativity is a phenomenon in which binding of one or more molecules of a ligand to a multimeric receptor makes subsequent ligand molecules more difficult to bind. Negative cooperativity can make the response of a multimeric receptor more graded than it would otherwise be. Negative cooperativity occurs when the binding of a first ligand or substrate molecule reduces the rate of subsequent binding. This definition does not apply only to ligand-receptor binding; it applies whenever two or more molecules have two consecutive binding events.
