Codominance

Explanation:

Their offspring receives one version of a gene, called an allele, from each parent.

This means neither parent is dominant over the other in the inheritance pattern, so it is called codominance.

Split-brain patients have undergone a surgery that severs the corpus callosum, the band of fibers that connects the two hemispheres of the brain. This means that information received through the right senses (ear, eye, or side of the body) is processed by the left hemisphere and vice versa. The correct answer is c)Speak about info received exclusively in their left hemisphere.

Split-brain patients are unable to speak about information received exclusively through their left hemisphere because that information cannot be transferred to the language centers in the left hemisphere for verbal expression. However, they can perform tasks that involve integrating logical and spatial information because both hemispheres are still able to process information independently. They may also have difficulty coordinating movements between major and minor muscle groups, but this is not a specific symptom of split-brain syndrome.

The modification that is most likely to alter the rate at which a DNA fragment moves through a gel during electrophoresis is increasing the length of the DNA fragment, option C is correct.

During electrophoresis, DNA fragments migrate through a gel matrix based on their size and charge. Longer DNA fragments experience more resistance from the gel matrix and migrate slower than shorter fragments.

Altering the nucleotide sequence without changing the length, is less likely to affect the migration rate significantly as the charge and size of the fragment remain the same. Radioactively labeling specific bases, does not directly affect the fragment's size or charge and is unlikely to impact the migration rate. Leaving the length of the DNA fragment the same, would maintain the original migration rate, assuming other factors remain constant, option C is correct.

Answer:

The person you are seeking is Castiel

Explanation:

The five evidences that support the theory of evolution are: Fossils, Anatomy, Embryology, Molecular Biology (or Biochemistry), and Biogeography.

Fossils show the physical change in a species over time, suggesting evidence for evolution. For an example, we can trace the origins of dolphins and whales all the way to a four-legged, dog-like hoofed mammal from about 50 mya. These mammals were fish eaters and so decided to spend a lot of time in the water. In fact, they spent so much time in the water, that in a few million years, they evolved a longer body and webbed feet. Then another few million years passed and they swapped their webbed feet for flippers and swapped their tail of a fin. Eventually, we get a fish-like mammal that once walked on land.

For anatomy, or structures, there's three types of structure comparisons: Homologous structures, Vestigial structures, and Analogous structures (or Convergent Evolution). Homologous structures show similarities between the structures between species, but serve different purposes. For an example, all mammals share common features within their arms, such as having 5 fingers. However, they serve different purposes, from whale fins for swimming, to bat wings for flying, to human hands for grabbing and for using tools.

Vestigial structures were structures that once served a purpose and have been reduced in size/power to the point where it's useless. For an example, large theropods such as the T. Rex spent so much time evolving more jaw muscles and biting power, that they sacrificed their arm muscles for such power. This explains why their arms were so short.

Another example would be ratites, flightless birds such as ostriches, emus, and cassowaries (penguins and kakapos are from a different group). They spent so much time evolving powerful legs as well as evolving in size, that there was no need to fly when they could just run with their improved legs. And also the fact that they're too heavy to even fly anyways.

Analogous structures is the similar functions of structures between species, but have separately evolved these functions. For an example, the wings from insects, birds, bats, and pterosaurs are very similar in shape and can be used to fly, but they've evolved separately. For an example, birds use feathers to fly while bats and pterosaurs use/used (pterosaurs are extinct) membrane between their bones to fly. Although they do have strikingly similar evolutionary histories, with their ancestors starting off as tree dwellers, they've evolved their flight abilities separately during different earth periods.

Embryology is evidence for evolution by using embryos from different species to suggest a common ancestor. For an example, we can prove that we're more related to whales than to fish by using embryos. The fish embryo will evolve gills while the embryos of humans and whales will not, since we do not breath by extracting oxygen from water.

Molecular biology is a more recent way of providing evidence for evolution. By taking the DNA from cells from different species, we can get an estimate of how related one species is to another. The more similar amino acid sequences are between species, the more recent their common ancestor is. For an example, by comparing amino acid sequences between humans and chimpanzees, we get an estimated amount that we once shared a common ancestor seven million years ago. Without molecular biology, we would still be digging for fossils to find that number.

Biogeography is the geographic distribution of species on earth that can be explained by evolution. For an example, we can tell that Australia separated first from Pangea rather than Asia or North America since Australia doesn't have bears while the Asia and North America do, with China having pandas and North America having brown and black bears. And also with the fact that Australia is the only continent with monotremes (egg-laying mammals like the platypus).

Similar to biogeography, there's also direct observation, which is evolution that has happened in our own eyes. An example would be the underground London mosquito. Mosquitoes usually target birds like pigeons. But after an underground tunnel was built in London, some mosquitoes managed to get inside and instead of birds, they targeted, mice, rats, and of course, humans. After only a few hundred years, a mosquito from the underground tried to mate with another mosquito from land and they could not, simply because they were different species. This shows that their new choice of feeding on mammalian blood has actually altered their DNA and created a new species, during the existence of humanity!

The statement is True, not all the data in a DNS cache has an expiration value. DNS (Domain Name System) cache is a temporary database maintained by a DNS resolver on a user's computer. It stores DNS query results for a specific period to speed up future requests for the same domain name.

DNS servers contain a list of domain names that they have recently resolved, allowing them to respond quickly to new requests for the same domain name.Certain types of DNS records, such as A records, typically have an expiration value known as a TTL (Time-to-Live). This value determines the length of time a DNS resolver is allowed to cache the results of a DNS query.

However, not all types of DNS records have an expiration value, such as NS records, which specify the authoritative DNS servers for a domain name. These records are not subject to expiration, and the DNS resolver must make a new query to retrieve the updated information. Therefore, while TTLs are commonly used to control caching behavior, not all data in a DNS cache has an expiration value.

On the analysis of GC content in human DNA, it is 40.9%, by following the base pair rule, the adenine and thymine are in approx. 60% composition, on dividing it by 2 we can conclude that adenine is 30.9% because adenine pairs with thymine with hydrogen bonds in the DNA.

One of the four aromatic bases contained in DNA and RNA, adenine, has a low water solubility. In fact, a number of tiny oligomers can be found in adenine solutions with low concentrations that appear to be perfectly clear. Adenine's aromatic structure, which is rejected by water, is what drives the oligomerization of the substance. In addition to this entropic contribution, aromatic pi-pi stacking, a type of contact that is crucial for protein structure, further stabilizes the noncovalent connections between adenine molecules.

According to the base pairing rule, guanine and adenine can only pair with cytosine and thymine, respectively. Adenine and thymine base pairs form two hydrogen bonds, while guanine and cytosine base pairs form three hydrogen bonds.

Hence, on the analysis of GC content in human DNA, it is 40.9%, by following the base pair rule, the adenine and thymine are in approx. 60% composition, on dividing it by 2 we can conclude that adenine is 30.9% because adenine pairs with thymine with hydrogen bonds in the DNA.

Light-dependent reactions of photosynthesis occur in the presence of light and occur in the thylakoid membranes. Water molecule splits during the reaction.

During the light reaction of the photosynthesis, the water and the carbon dioxide along the light is absorbed by the chlorophyll of the plant.

The reactants excite the electron and the replaced electron from the membrane is replaced by the separation or the splitting of the water molecule.

The molecule of the water splits to form hydrogen ions \((\rm H^{+})\), oxygen \(\rm (O_{2})\) and releases an electron.

Therefore, water splits during the photosynthetic reaction.

Less likely to be eaten by birds

The similarity in appearance between monarch butterflies and viceroy butterflies developed because viceroy butterflies that closely resemble monarchs are less likely to be eaten by birds. Thus, option B is correct.

Limenitis archippus is scientific name of viceroy butterflies which is a North American butterfly. Since the viceroy is distasteful to predators, it is considered a Müllerian mimic.

The viceroy found in most of the contiguous United States as well as parts of Canada as well as Mexico. The caterpillar of viceroy butterflies feeds on trees in the willow family Salicaceae which includes willows, poplars, cottonwoods. The caterpillars isolate salicylic acid in their bodies, and therefore tastes bitter, and upsets predators' stomachs.

In natural phenomenon called Müllerian mimicry two or more well-defended species, which are foul-tasting and sharing common predators, mimic each other's honest warning signals.

Therefore, Monarch butterflies and viceroy butterflies are  less likely to be eaten by birds so option B is correct.
