New fossil primates are recovered in a stratigraphic layer of volcanic ash that includes fossil molars of a pig species known to have become extinct about 30 million years ago. Identify the fossil dating methods that are appropriate to use in determining the age of the fossil primates. Correct Dating Methods inquizitive

Answers

Answer 1

Answer:

The correct dating methods will be:

radiopotassium datingbiostratigraphic dating

Explanation:

The primate fossils presented in the question above must be submitted to the dating processes known as radiopotassium and biostratigraphic so that the age of these fossils can be determined as accurately as possible.

Radiopotassium dating is based on the half-life of potassium, which is equal to 40 years. The term half-life refers to the number of years it takes for half the number of atoms of the radioactive isotope to be destroyed. Thus, radiopotassium dating measures the amount of potassium present in a fossil and relates this amount to the half-life of potassium, thus being able to calculate the age of the fossil.

Biostratigraphic dating, on the other hand, allows the age of a fossil to be determined by being compared with the age of another fossil and the physical and structural composition that these fossils have.

Therefore, to determine the age of primate fossils, radiopotassium dating would first be used in some fossils. These would be used as a model during biostratigraphic dating, allowing confirmation of the age of other fossils.

Answer: Nonvascular plants

Explanation:

Non-vascular plants are the plants that do not have a vascular system that has a xylem and phloem but rather, they have simpler tissues which have specialized functions that are used in the internal transport of water.

The type of plant that was important in establishing the transition from water to land and the dominance of gametophyte is the non vascular plant.

Scientists have noted patterns in the Earth's seafloor structures. For example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. In addition, seafloor rocks found at the trenches are usually older than seafloor rocks found at the volcanic ridges. Which explanation of the past movement of the Earth's plates is best supported by this information? A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges. B. The continents were separated when new crust that formed at the edges of the continents pushed older crust towards the center of the ocean. C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another. D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.

Answers

Answer:

A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.

Explanation:

The crust is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types:

I. Divergent

II. Convergent

III. Transforming

In divergent boundaries, a new crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

Answers

Answer:

glycerol and fatty acids.

Explanation:

Fats as biological molecules can be used as energy sources by the cell when there is low or no carbohydrate (glucose) for use.

Fats, mainly triglycerides enter metabolic pathway in an aerobic condition where they undergo catabolism to produce glycerol and fatty acids, their monomeric units. This process leads to the synthesis of ATP (Adenosine triphosphate). In other words, fats are hydrolyzed to glycerol and fatty acids

A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.

Answers

Answer: Living Planet Index

Explanation:

The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.  

With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.  

The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.

The rapid diversification of species seen in the fossil record followed by long periods of stasis is part of the ________ model of evolution.

Answers

Answer:

punctuated equilibrium

Explanation:

According to the punctuated equilibrium model of evolution, the process of evolution involves a sudden spontaneous burst in the diversity of species (speciation).

This period is now followed by a long period in which the there is no change in the species. This period is known as the period of stasis or equilibrium.

Hence, the rapid diversification of species seen in the fossil record followed by long periods of stasis is typical of the punctuated equilibrium model of evolution.

The fields of antebellum (pre-Civil War) political history and womens history use separate sources and focus on separate issues. Political historians, examining sources such as voting records, newspapers, and politicians writings, focus on the emergence in the 1840s of a new "American political nation," and since women were neither voters nor politicians, they receive little discussion. Womens historians, meanwhile, have shown little interest in the subject of party politics, instead drawing on personal papers, legal records such as wills, and records of female associations to illuminate womens domestic lives, their moral reform activities, and the emergence of the womans rights movement.However, most historians have underestimated the extent and significance of womens political allegiance in the antebellum period. For example, in the presidential election campaigns of the 1840s, the Virginia Whig party strove to win the allegiance of Virginias women by inviting them to rallies and speeches. According to Whig propaganda, women who turned out at the partys rallies gathered information that enabled them to mold party-loyal families, reminded men of moral values that transcended party loyalty, and conferred moral standing on the party. Virginia Democrats, in response, began to make similar appeals to women as well. By the mid-1850s the inclusion of women in the rituals of party politics had become commonplace and the ideology that justified such inclusion had been assimilated by the Democrats.The primary purpose of the passage as a whole is toA. examine the tactics of antebellum political parties with regard to womenB. trace the effect of politics on the emergence of the womans rights movementC. point out a deficiency in the study of a particular historical periodD. discuss the ideologies of opposing antebellum political partiesE. contrast the methodologies in two differing fields of historical inquiry 15.
