Explanation:
The Paleozoic era lasted for approximately 291 million years. The The Paleozoic Era is a significant period in the geological history of the planet.
The Paleozoic Era, commonly referred to as the Age of Ancient Life, is a key period in the geological history of the Earth, lasting roughly between 541 and 252 million years ago. The Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian are its six distinct time eras. The Paleozoic Era saw incredible evolution and the creation of numerous life forms, which laid the groundwork for the diversity of life that can be seen on Earth today. Life underwent a remarkable period of diversity during the Cambrian Period known as the "Cambrian explosion." Trilobites, brachiopods, and early arthropods were among the complex, hard-shelled animals that first emerged as a result of this surge.

Answer:
The correct answer is - Humans should leave primary growth forests and their residents intact, and ensure that secondary growth forests have a chance to regrow.
Explanation:
Humans should not clear the forest at any cost as cutting the forest affect the flora and fauna of the forest and residents of the forest lose their habitat. The clearing or affecting the habitat leads to an increase in the global warming as there is increase in the carbon dioxide gas.
Humans need to intact the primary growth and flora and fauna of the ecosystem. It also need to be ensure that forests have cahnce to regrow. It should be also put in consideration that inhabitants should be protected.
The early ancestors of horses showed the presence of digits on their limbs, while modern horses have hooves. What are likely possible reasons for this change?
Answer:
Natural Selection & Fitness
Explanation:
Horses have evolved to run as fast as possible because they are prey animals.
The hooves give advantages to the predecessors to the modern horse rather than the foot-bearing horses.
Thus when somebody inevitably becomes a snack, the hoof bearing horses lived longer. (Natural selection)
Because they've lived longer, they've had more babies. (Fitness)
Their babies are more likely to pass on the genes they've inherited from their successful parents, and the population of hooved-horses begins to exceed the population of footed-horses.
In this circumstance, all the footed-horses are gone. The population has evolved.

Answer:
DiversityStabilityBiodiversityCosmopolitanEndemicEcosystemPopulationSpeciesExoticExplanation:
Diversity: Diversity as a term is broad and might be used in many aspects, referring to things variety. Diversity in biological terms refers to the present or the past forms of life inhabiting a natural environment. Stability: Related to the resilience concept. Stability depends on the quantity and magnitude of disturbances affecting an ecosystem. If there are no disturbances, the ecosystem is stable. If there are some or many disturbances of small magnitude, the ecosystem remains relatively stable, with a high resilient capability. But when the ecosystem is affected by frequent and severe disturbances, it loses stability and might be seriously affected.Biodiversity: Defined as the different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species conform.Cosmopolitan: Referred to as any taxonomic group that live all around the world. Species might be cosmopolitan, or genera, or classes. Sometimes a superior taxonomic group is cosmopolitan, but the species composing it are not. Endemic: Referred to species or any other taxonomic group restricted to a certain area or region, which provides all the environmental requirements of these organisms. They are usually small groups that might be in danger of extinction due to any alteration that might change their environment. They might also be a new species that did not have enough time to disperse yet.Ecosystem: Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors. Population: Groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring, and living in the same habitat at the same time.Species: Organisms that are morphologically and genetically similar, that can mate, reproduce and leave fertile offspring to the next generation. Members of populations. Exotic: It refers to new species that establish in a new area far or out of their original distribution range. The dispersion of these species to new areas might be accidental or intentional. Once established, these species might be considered invasive if their reproductive rate increases, if their population over-growth, and there is a negative interaction with native species.The enzyme pepsin is produced in the cells of the stomach but not in the cells of the small intestine. The small intestine produces a different enzyme, trypsin. The reason that the stomach and small intestine produce different enzymes is that the gene that codes for pepsin is A) in the cells of the stomach, but not in the cells of the small intestine B) mutated in the small intestine C) digested by the trypsin in the small intestine D) expressed in the stomach but not expressed in the small intestine
Answer:
D) Expressed in the stomach, but not in the cells of the small intestine
Explanation:
The stomach and small intestine produce different enzymes is gene codes for pepsin is expressed in the stomach but not expressed in small intestine.
What is the function of trypsin?Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, the process of digestion that formed in the stomach.
Is a proteolytic enzyme produced by the pancreas in an inactive form called trypsinogen.

autotrophic means they make their own food. such as plants and heterotrophs is anything that eats other things to obtain energy. so this could be the second or third trophic level just depends on all the information you are given and what you want to choose.
The name of one trophic level that contains autotrophs is Producers, while the name of one trophic level that contains heterotrophs is the primary consumer.
What do you mean by Trophic level?A Trophic level may be defined as a sequential position of organisms in a food chain of an ecosystem.
Autotrophs are those groups of organisms that synthesize their own food in the presence of sunlight. They are the foundation of the trophic level.
Heterotrophs are those groups of organisms that depend on autotrophs in order to take energy for metabolism and other work.
Therefore, the name of one trophic level that contains autotrophs is Producers, while the name of one trophic level that contains heterotrophs is the primary consumer.

Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.

They can create deep valleys is true about folds.
What are Deep valleys?
The combined effects of gravity, water, and ice result in valleys, which are low-lying sections of land that have been eroded and washed out. Some are hollow, while others hang.
The majority of primary valley cuts are made by rivers and streams, creating sides with high walls and a narrow floor that from a distance resembles the letter "V." The steepness of the sides and the width of the floor are both influenced by the gradient of the river, or how quickly it descends.
Waters add to the land's natural twists as they move toward the sea by removing sediment from bends' exteriors.
