If we traced the sensory pathways that carry sarah's thigh pain up to her brain, which cerebral lobe and which part of the cortex would be active when she feels this sensation?
Answer:
Parietal lobe and left primary somatosensory cortex
Explanation:
The parietal lobe is that area of integration where it passes much of the information from the rest of the brain regions. It is he who organizes, who allows us to feel and understand the reality around us. It is through him that we perceive the touch of someone, the feeling of the hug and the force of a blow that causes pain.
In addition to the parietal lobe, the primary sensory cortex is also responsible for receiving tactile information from the body. Thus, we can state that when we feel a physical pain, such as Sarah who is experiencing leg pain, the parietal lobe and primary sensory cortex will be active.

A bird population only eats a certain type of plant. One year, flooding washes away most of these plants in an area. What will most likely result?
immigration followed by competition
competition followed by immigration
emigration followed by competition
competition followed by emigration
Answer:
competition followed by immigration
Explanation:
If the bird population eats only a specific species of plant and most of the plant population has been exterminated due to flooding, competition will occur followed by immigration of these birds. This is because the amount of plants has been reduced, resulting in poor availability of food for the birds, which will compete for the few remaining plants. After the birds consume the remaining plants, they will migrate to other regions in search of food.

Why are all of the organs in the alimentary canal important in digesting food? As food passes through each organ, different hormones are produce to help break it down so that our body can easily absorb nutrients. Each organ has the same role in digesting food but is necessary in order to efficiently break food. The human body needs a long time to digest food in order to be able to absorb nutrients.
Answer:
the first one

According to computer models, most coastal areas will experience what effect of global warming
increased flooding .
all late but that's the answer :)
Most of the coastal regions will experience increased flooding because of global warming.
Due to global warming, the levels of the sea will rise mainly due to two reasons. First, with the increase in temperature, huge amounts of ice in the polar caps will melt, increasing the volume of water in the oceans. Secondly, the substances seem to expand when it gets heated, that is, known as thermal expansion.
Thus, if the average temperature of the Earth rises, the water in the ocean will expand, leading to rising sea levels. One prime influence of rising sea levels is that coastal regions will encounter with more flooding, mainly due to storm surges at the time of typhoons or hurricanes.

Imagine that you have the dna sequences from the intron of a gene in three species called a, b, and
c. species a and b are most closely related, while c is more distantly related. the sequences of a and b differ by 18 base pairs, a and c differ by 26 base pairs, and b and c differ by 28 base pairs. fossils show that species a and b diverged about 1.2 mya, but there is no fossil evidence as to when the most recent common ancestor of all three species lived. use the genetic data to estimate that date. what assumptions are you making to get this estimate?
By assuming a consistent rate of genetic change, this analysis approximates that the most recent common ancestor of all three species lived approximately 1.87 million years ago.
Explanation:Estimating the timing of species divergence using genetic data involves some assumptions. First, we assume a constant molecular clock, meaning that genetic changes accumulate at a consistent rate over time. Second, we assume that differences in DNA sequences are reflective of the time since species diverged.
Given the divergence of species A and B is known to be 1.2 million years ago (mya) and this corresponds to a difference of 18 base pairs, it suggests that the mutation rate is 15 base pairs per million years. If we apply this rate to other pairings, the divergence of species A and C, which have a difference of 26 base pairs, would be approximately 1.73 mya, and B and C, which differ by 28 base pairs, diverged approximately 1.87 mya.
The most recent common ancestor of all three species would be the most distant divergence, which is between B and C at approximately 1.87 mya.

Consider the cladogram. mc014-1.jpg Which group of organisms has the derived characteristics of true tissues, bilateral symmetry, and a pseudocoelom
sponges
roundworms
annelids
chordates
The right answer is roundworms
In the scientific sense, worm refers to the primitive form of organization of the Bilaterians. The three groups of animals (roundworms, flatworms and ringed worms) have a fundamental bilateral symmetry. Their appearance, probably at the very beginning of the Cambrian (primary era), marks an important stage in the evolution of living beings. In spite of their apparent simplicity, they inaugurate a new type of anatomical organization which will then be taken over by all other animal species. The different tissues or specialized organs, come from one of the three embryonic leaves (endoderm, mesoderm and ectoderm) inaugurated by these verses.

Members of the Protista kingdom contain multi-celled organisms such as kelp and single-celled organisms such as .
Answer:
The correct answer will be Paramecium.
Explanation:
Protista is a heterogeneous group of simple eukaryotic organisms which did not arise from a single ancestral protist.
The members of protist are polyphyletic, which means they are not closely related to each other and do not share many common characters. They vary greatly in organization from single-celled to synctial to multi-cellular organisms.
The most common single-celled protista is Paramecium.
Paramecium are unicellular protist found in freshwater habitats, shaped like a sole of a shoe with short hairy structures on its body called cillia. Cillia helps in locomotion and dragging the food to its oral cavity.
Thus, Paramecium is the correct answer.
