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.

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.

Provide a summary of Professor Steve Jones’ findings concerning how Natural Selection may be working today in humans.
Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):
Jones, JS. (2012). Is Human Evolution Over?. In Evolution 2.0 (pp. 167-176). Springer, Berlin, Heidelberg.
explain the difference between the principles of overload and progression
Describe natural selection
Answer:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Explanation:
How can a genetic mutation lead to an adaptation in a species
Answer:

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.

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.

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.
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.

What is a “shared derived character”?
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.
In your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. One rattlesnake has a mutation and cannot produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: AATCGCCATGCACGTCAG
There's a difference within the 7th, 8th, and ninth letter of the mutated snake in comparison to the regular.
Venom glands are present in most spiders, but they are absent inside the family Uloboridae. The glands are positioned either inside the chelicerae or under the carapace. The venom ducts enlarge through the chelicerae and open near the suggestions of the fangs.
