Answer:
Evidence of fossil apes and hominids in both East and West of the great rift valley
Explanation:
The East Side Story hypothesis opined that a tectonic plate movement created a seismic split in the earth, thus deepened the rift valley and created a geographical barrier between the east and the west of the great rift valley. The barrier created a kind of geographical isolation between the ancestors of hominids, dividing them into two with each population taking different evolutionary paths.
Thereafter, the ancestors in the western side of the rift valley evolved into the chimpanzee's family while those in the eastern side ultimately evolved into humans.
Thus, providing the fossils of apes and that of hominids in both East and West sides of the great rift valley will render the hypothesis invalid.
While snorkeling in the ocean you find large, leafy organisms that are brownish in color growing in large masses. You are unsure whether they are protists since they look quite plant-like. If they are actually protists, what characteristic will the organism's cells exhibit?
A. Each of the cells in the organism will have its own nucleus.
B. The cells will form a colony with separate groups of cells doing various jobs.
C. The cells will form a colony without differentiating into separate tissues.
D. Most of the cells in the organism will have cilia or flagella.
Answer:
A. Each of the cells in the organism will have its own nucleus.
Explanation:
While snorkeling in the ocean you find large, leafy organisms that are brownish in color growing in large masses. To be sure that they are protists since they look quite plant-like, the characteristic that the organism's cells exhibit will be that each of the cells in the organism will have its own nucleus.
This is because protists are eukaryotes, which simply means it has its own nucleus and are usually single celled.

Why is it important that saline solution has a specific concentration when a person is put on an IV drip of saline?
Answer:
Doctors utilize IV saline for refilling lost fluids, flushing wounds, providing medication, and maintaining patients through surgery, dialysis, and chemical treatment. As a fashionable therapy, Saline IVs even found a space outside the hospital.
"There are significant quantities of sodium and chloride, higher than blood levels.
Explanation:
The solution of sodium chloride-water, generally known as saline, is the saline solution. It is the intravenous fluid most usually used. It was utilized since the early decades of the 19th century and is used annually in the United States alone with more than 200 million liters.
Though about 60 percent of the body consists of water, it is not possible to inject water into the blood alone, because the blood could lead to the depletion of important electrolytes.
Direct water injection into the bloodstream would likewise lead to the blood cells' osmotic impact.
Blood cells, which are predominantly salty, will take water and cause it to expand quickly until the cell membrane breaks down. The content of the cells would then leak into the plasma. A substantial proportion of body cells can be damaged to death. Death can result.
There would be no permanent harm to a little amount of water injected into the blood directly. The bigger the number of cells injured, in essence, the more water injects into the circulation.
Water is blended in a solution in sodium and chlorine at approximately the same concentration as blood plasma to avoid damages caused by pure distilled water on blood cells. The outcome is that the solution splits the circulating volume with the cellular fluid and becomes an integral part of the circulating volume without a detrimental influence on blood cells.
In these imprinted cells, the SNRPN transcript overlaps with another gene, called UBE3A, which is transcribed in the opposite direction. This means that the region that the RNA polymerase transcribes in these two genes actually overlaps; in some cases, overlapping transcription in opposite directions leads to transcriptional interference, meaning that collisions between the polymerases traveling in opposite directions can interfere with transcription. It is believed that this takes place in this case, meaning that the more SNRPN transcription occurs, the more this disrupts transcription of UBE3A. Based on this information as well as information about the effects of imprinting on SNRPN transcription, which of the following statements about UBE3A transcription would be true?
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
b. The paternal copy of UBE3A is expressed and the maternal copy is silenced.
c. Both copies of UBE3A are highly expressed.
d. Both copies of UBE3A are silenced.
Answer:
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
Explanation:
When UBE3A chromosome is in neurons, paternal allele is silent and maternal allele is expressed in process of genomic imprinting. In some cases UBE3A is expressed from both paternal and maternal chromosomes. The paternal chromosome is blue whereas maternal chromosome is magenta.
Classify each item as being associated with light positioning (controlling how and where light strikes the retina) or sensory processing (how that information is processed).
a. Photoreceptors
b. Occipital cortex
c. Extrinsic muscles
d. Pupil
e. Bipolar cells
Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.

Answer:
The correct answer is - Aorta or descending aorta.
Explanation:
The main artery carries blood from the left ventricle of the heart to the rest of the body and going downwards in the torso is the aorta. The blood leaves the heart through the aortic valve making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells. It is known as the largest artery of the human body.
The correct answer is - Aorta or descending aorta.

One of the most important outcomes of extreme stress or tension is the effect on the ___________ system, which usually protects use from invading toxins and micro-organisms that can negatively impact our health.
Answer:
Immune
Explanation:
The immune system helps to protect our body from all sort of organisms ranging from invading toxins and micro-organisms which negatively affects an individual’s health and well being.
Stress has an adverse effect on the immune system such that it weakens and suppresses the functions of the required antibodies in the body system. This is the reason why many aged people fall sick because they have gone through more stress when compared to younger people.
Senario: 2 years ago, a fruit was smuggled into California on a plane from an exotic, far away land. The homeowner saw that the fruit had maggots and tossed it into the backyard, hoping the seed would grow. The larvae hatched out and moved throughout the area. This fictitious insect will destroy fruit and has the possibility of spreading disease killing the trees. The insect consumes plants in the Prunus species of stone fruits? Look up the plant genus Prunus.
Discussion: The insect has spread over a large area of Southern California, discovered at UC Riverside. What steps would you do to control or eradicate the destructive exotic insect?
Answer:
To destroy this insect, a chemical should be used or made that will fight the main power of the insect. Also the food that is targeted should be removed.

________________ best summarizes how Durkheim's approach to religion differed from that taken by Wallace.
Answer:
Durkheim underscored the common, public, and all-encompassing nature of religion. It also speaks to the definitions that it embodies and how it causes people to emote.
Explanation:
Durkheim is a sociologist of french origins who believed that society was more powerful than the individual.
This according to him, was so because society is held together by ideas that resonate across more than one individual. These ideas show up like norms, beliefs, and values which are subscribed to by many thus creating a collective consciousness. This collective consciousness makes it easy to predict how people generally are likely to behave either as a people or an individual.

Congestive heart failure (CHF) is an inability of the heart to pump sufficient blood to the body. One sign of CHF is excess fluid in the tissue spaces, known as edema. Describe the location of the edema if the left side of the heart fails, compared to the location of edema if the right side of the heart fails.
Answer:
Explanation:
When the left side of the heart (left ventricle) starts to fail, fluid collects in the lungs (edema). This extra fluid in the lungs (pulmonary congestion) makes it more difficult for the airways to expand as a person inhales. Breathing becomes more difficult and the person may feel short of breath, particularly with activity or when lying down.
When the right side of the heart (right ventricle) starts to fail, fluid begins to collect in the feet and lower legs. Puffy leg swelling (edema) is a sign of right heart failure, especially if the edema is pitting edema. With pitting edema, a finger pressed on the swollen leg leaves an imprint. Non-pitting edema is not caused by heart failure.
