Answer:
The correct dating methods will be:
radiopotassium datingbiostratigraphic datingExplanation:
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.

what molecule is used to store and release chemical potential energy in living things
a) ATP
b) RNA
c) DNA
d) ADP
Answer:
a) ATP
Explanation:
ATP is main source of energy that powers most of the living cells in the known parts of our universe.
Answer:
a) ATP
Explanation:
adenosine triphosphate (ATP)
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

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

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.
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.

The rapid diversification of species seen in the fossil record followed by long periods of stasis is part of the ________ model of evolution.
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.
Exfoliation is which type of weathering?
A. Biological
B. Physical
C. All of these
D. Chemical
Answer:
The answer is chemical weathering.
Explanation:
Cellular respiration converts the energy of fuel molecules to a form of energy that a cell can use to perform work. In an average day, most adult humans need to consume about 2,000 Calories to maintain their health. However, the exact amount of dietary Calories a person needs depends upon many factors, including the person's age, physical activity, size, and health. Foods that we consume vary greatly in their nutritional content and quality. A large hard-boiled egg, for example, has about 75 dietary Calories and contains about 70% of our recommended daily intake of cholesterol. A person eats one hard-boiled egg and digests the egg fully. During cellular respiration MOST of the Calories in the egg is converted to ________.
Answer:
A person eats one hard-boiled egg and digests the egg fully. During cellular respiration MOST of the Calories in the egg is converted to heat.

When a cell uses fatty acids for aerobic respiration, it first hydrolyzes fats to Group of answer choices glycerol and fatty acids. glycerol and amino acids. fatty acids and sugars. sugars and glycerol.
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

The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates
Answer:
Answer to the following question is as follows;
Explanation:
Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.
Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.
