Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

A biologist analyzes DNA sequences in three different primates. She finds primates "A" and "B" have almost exactly the same DNA sequences. DNA sequences in primate "C" are significantly different from those of primate "A" and primate "B". This information allows the biologist to infer that
Answer:
primates A and B are more closely related to each other than they are to primate C
Explanation:
The study and the comparison of DNA sequences of various species is used in decoding genomic information as well as determining closely related or distant related species.
Closely related species are known to have almost the same DNA sequences when studied. For example, chimpanzees are known to be most closely related to humans and this because, studies show that they share about 99% of their DNA with humans. So also, although monkey is a primate, its DNA sequences is significantly different from humans and chimpanzee, making it less closely related to either humans or chimpanzee compared to the relationship between human and chimpanzee.

What occurs during a solar eclipse? Select two options.
Answer:
A solar eclipse happens when the moon moves in front of the Sun as seen from a location on Earth. During a solar eclipse, it gets dimer and dimmer outside as more and more of the Sun is covered by the Moon. During a total eclipse, the entire Sun is covered for a few minutes and it becomes very dark outside.

C. Deuterostomes
D. Sponges
Answer: D sponges, i just got this wrong lol
Explanation:
Why sponges develop first?
Sponges belong to the oldest and most simple animals that had evolved, and their discovery in such old rocks meant that they may have been the first animals.
How did sponges evolve?
Among extant animals, only sponges could have evolved directly from protozoa without changing feeding mode.

Do you think that the frequency of echolocation sounds from bottlenose dolphins will be higher or lower than that of the blue whale call described in activity one?
Answer:
The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.
However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.

Which three descriptions or examples can be classified as endocrine control?
vasopressin acts on renal cells to maintain the body's water and salt balance
regulates the body using electrical signals
a reflex causes the body to move in response to a stimulus
aldosterone causes the kidneys to reabsorb water
regulates the body using hormones
a signal initiates the contraction of a muscle
Answer:
vasopressin acts on renal cells to maintain the body's water and salt balance
aldosterone causes the kidneys to reabsorb water
regulates the body using hormones
Explanation:
if i pick all of them i see which ones are right and which ones are wrong, your welcome :)
The three descriptions that can be classified as endocrine control are :
Vasopressin acts on renal cells to maintain the body's water and salt balance ( A ) Aldosterone causes the kidneys to reabsorb water ( D ) Regulates the body using hormones ( E )Endocrine control is the process of controlling, mood, growth and development by the endocrine hormones. The amount of endocrine hormones produced is dependent on the amount of hormones present already in the system of an individual and it is regulated by the endocrine system.
Some of the functions performed by the Endocrine system includes the regulation of body using hormones, aldosterone which is an endocrine hormone causing kidneys to reabsorb water.
Hence we can conclude that the three descriptions of endocrine control is as listed above.

Which causes waves in the ocean to occur?
Earth’s rotation
Earth’s gravitational pull
energy being transferred from wind
energy from the Sun heating water
Answer: Energy being transferred from wind
Explanation: I just answered this question
Waves in the ocean are occurs due to the transfer of energy from the wind. Therefore, option C is correct.
What causes waves in the ocean?Numerous events, including earthquakes, volcanic eruptions, and landslides, can result in waves, although surface waves brought on by winds are the most frequent ones (CoastalCare). A wave forms when the wind blows across the water's surface, generating friction between the air and the water.
There are numerous types of waves, including tidal waves, wind waves, ocean swells, and tsunamis. Three factors: the wind's speed, the length of time it takes to cross the ocean, and the distance it travels, all affect how large the waves become.
The most common cause of the formation of waves in the ocean is the transfer of energy from the wind. Therefore, option C is correct.

Tickleback evolution lab final quiz 1. how did some ancestral sea-run stickleback populations come to live exclusively in fresh water? these populations swam to freshwater lakes to spawn and then never returned to the ocean because there were fewer predators in lakes. they became trapped in lakes that formed at the end of the last ice age. they don't actually live exclusively in fresh water; they only live in fresh water at certain stages in their lives. they developed traits that made them better adapted to fresh water and, as a result, had to move to a freshwater environment to survive.
Answer:
The correct answer is "some stickleback populations come to live exclusively in fresh water they became trapped in lakes that formed at the end of the last ice age".
Explanation:
There are different types of speciation. Allopatric speciation consists of the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations. Some barriers might impede the genetic interchange or genetic flux, making a place to two new populations that are separated and can not get together to mate anymore. Glaciation is one of the most important drivers of speciation and production of different phylogeographic structures by vicariance. Glacials originate isolated gene-pools that accumulate differences that end in reproductive isolation. Melting of the ice also generated divergence and speciation, as land appearance acted as a barrier for some populations.
During the last glaciation, stickleback fishes were able to reach certain new places or areas that provided better conditions to inhabit. There were fewer predators and more available food sources that made these new areas to be a better choice. These new grounds were lakes and were the product of ice melting. But at a certain point, as ice melting increased, the land started to show up again and became a barrier for this species. Animals that were living in lakes could not go back to the sea, they were trapped so they had to adapt to living exclusively in lakes. This species diverged and suffered speciation.
