Explanation:
Which statement is correct? Carbon dioxide diffuses from the alveoli into surrounding capillaries. In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells. Oxygen is released from the mitochondria as a product of cellular respiration. As oxygen diffuses from the lungs into capillaries, blood becomes deoxygenated. Oxygen diffuses from large blood vessels into the body's cells.
Answer:
In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells.
Explanation:
The blood contains a protein called hemoglobin. This protein has the important use of ensuring oxygen is bound to the blood for distribution to other parts of the body. The oxygen helps in the vital functioning and metabolism of the various body parts.
This explains why In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells Is the right choice.
Around the Grand Canyon the predators of deer were largely exterminated by people. The deer population grew rapidly as a result of the lack of predators until the deer exhausted their food supply. This led to a massive die-off (known as a population crash) and hundreds of deer died of starvation. The point at which the food supply no longer supported the large deer population can best be considered a

Because the theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle.
How is the human body organized to maintain homeostasis?
Answer: The human body is an exquisite machine, partly because it maintains functionality in a variety of environments. Humans can thrive in conditions ranging from the arctic to the equator, and with a variety of diets and lifestyles. Part of the reason for this adaptability is the body’s ability to maintain homeostasis.
Answer:
[tex]\boxed{\mathrm{view \: explanation}}[/tex]
Explanation:
The organs that work in the human body are mainly responsible for maintaining homeostasis.
The body maintains homeostasis by excreting toxins and unnecessary materials from the body fluids. The nervous system helps keep homeostasis in maintaining rate of respiration. The internal body temperature of Humans is an example of homeostasis, because we can maintain different temperatures.

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with rabbit hemoglobin genes a bacterium that has been treated with a compound that affects the expression of many of its genes a fern grown in cell culture from a single fern root cell a houseplant propagated from the cuttings of another houseplant
Answer:
a rat with rabbit hemoglobin genes
Explanation:
When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.
This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.
Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.
Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.
Genetically modified bananas as edible vaccines are another example

Explain why eating a meal with too much salt leads to production of small volume of concentrated urine.
Answer:
the urine is burned up by salt which will evaporate
Answer:
Eating a meal with too much salt leads to a decrease in the water potential of blood. This fall in water potential is detected by the osmoreceptors in the hypothalamus (in brain). The hypothalamus stimulates the pituitary gland to release antidiuretic hormone (ADH). The walls of the collecting duct in the kidney become more permeable to water, hence, a greater proportion of water is reabsorbed from the urine back into the blood by osmosis.
As a result, a small volume of concentrated urine is formed.
Which best contrasts self-renewal and differentiation?
Answer:
Self-renewal is a kind of cell division specific to stem cells, so cell division is a general term. When self-renewal occurs, a stem cell divides into two cells, one of which is still a stem cell (which can display differentiation potential into one or more types of differentiated cells (stemness/potency) and divides almost indefinitely = self-renewal), and another is a differentiated cell, which may or may not divide, but its divisions (if any) are not self-renewal because (1) no stem cell (i.e. a cell with developmental potential) is produced, and (2) these divisions are finite (so they are not self-renewal, because self-renewal is indefinite yet controlled proliferation). In sum, self-renewal is a stem cell's 'unlimited' division while retaining its developmental potential.
Of note, stem cell immortality is thanks to the expression of the enzyme telomerase.

The top soil can produce runoff if it rains heavily and travel with the water. The pesticides in the water are harmful to our body when consuming it. The pesticides are in the topsoil, therefor when the soil runs into the water system it is now contaminated with pesticides.
In "Landscape with the Fall of Icarus," what does Williams's use of the word
"unsignificantly" suggest about the drowning of Icarus?
A. That it is historical
B. That it is unusual
C. That it is exciting
D. That it is not important
Answer:
D. That it is not important
Explanation:
The word "unsignificantly" suggest that Icarus drowned near the coast which was not important because he was unable to swim due to weight of the feathers. This poem shows the carelessness of the Icarus by flying too high which cost his life. His father advice him not to fly too close to the sun but he ignored his father's advice and fly too high. Due to which the wax that binds the feather start melting and Icarus fell into the sea and die.

Explanation:
A blood lactic acid sample was collected in a gray-top tube that was drawn after sequentially filling red-top, green-top, and purple-top tubes. The lactate level was 30 mg/dL. A second lactic acid sample was ordered 1 hour later and drawn in a gray-top tube without filling any other tubes. The result was 20 mg/dL. What is the most likely explanation of this result
Answer:
Homeostasis has been established for a very long time. This must have affected the result of the first reading, which has become high.
Explanation:
Homeostasis refers to the state of equilibrium in the chemical and physical conditions of a system. The time it takes to establish, as well as the time it remains active within a system, provides different results, which are totally related to the homostatic forms presented.
The time between homeostasis in the blood lactic acid samples shown in the question above was what allowed the difference between the two reading results. The first result was high, because it was the result of an extended period of homeostasis.

differentiate Sympathetic and parasympathetic nervous system
Answer:
Sympathetic nervous system makes the body ready to fight or fight response during any danger in the body.
While
Parasympathetic nervous system slow the body from performing too much work there by restoring the body to calm and composed state
Explanation:
The autonomic nervous system is divided into two; the sympathetic and parasympathetic nervous system. The autonomic nervous system controls the involuntary actions of internal organs and glands.
The sympathetic nervous system originate from the spinal cord and and it's is responsible for accelerateing the heart rate, constricting blood vessels, and raising blood pressure. Thereby preparing the body to fight or fight response against any danger.
The parasympathetic nervous is a part of autonomic nervous system that also originate from the spinal cord which which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. By doing this,it prevent the body from overworking itself and restore the body to a calm and composed state.

which following pairs of body functions are normally involuntary actions but can be controlled voluntary for a short periods of time
Explanation:
Medulla oblongata controls consciousness and arousal (the reticular formation) and its three vital reflex centers control the blood vessels diameter, heartbeat and breathing rate (the involuntary actions). This makes option D correct. The lower part of brain stem forms the hind brain which comprises of medulla oblongata, pons and cerebellum. This makes option C incorrect as medulla is not part of forebrain. Cerebellum is the convoluted subdivision of brain stem and is associated with coordination of muscular movement, muscle tone and balance i.e. the voluntary actions. Option B is incorrect. Spinal cord, along with brain, forms central nervous system which serves to integrate the sensory inputs from internal and external environment as received by sensory neurons and process and finally transmit the nerve impulses to effectors (muscles and glands). This makes option A incorrect.
explain what is meant by emergent properties when explaining how a beaker full of chemicals is different than an animal made of that same mix of chemicals
Answer:
In biology, an emergent property is a property possessed by a collective and complex system of constituents, which is lacking in the individual component of the system
Emergent properties are therefore, an important aspect of biological system, for example, a beaker containing graphite (carbon) and ammonium ions in solution contains the same chemicals found in the human brain used to control movement and store memory whereas the chemicals in the beaker are idle.
Explanation:
identify the sphere wher life first emerged on earth hydrosphere, lithosphere, atmossphere
Answer:
hydroshere
Explanation:
hydro=water
Answer:
you're answer would be hydrosphere
Explanation:
Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.

You are at a conference for a fellow scientist who is giving a lecture in a field you
are both researching: human evolution and ancestry. In his lecture, he compares
many of the behaviors of humans and Chimpanzees, and compares the
behaviors of humans and Orangutans. He concludes that we are more closely
related to Orangutans than Chimpanzees. Is he correct?
Answer:
incorrect
Explanation:
This is an incorrect statement as orangutans are the most distant relatives of humans among the Great apes and chimpanzees are the closest.
What is the evolutionary relationship?
The link drawn between different species of organisms considering their evolutionary history is the evolutionary relationship between these species. Genome sequencing is a method to study evolutionary relationship between the organisms of different species.
The humans, orangutans, gorillas and chimpanzees are grouped together in a family called as as the Hominidae. The Genome sequencing of humans, chimpanzees and orangutans revealed that humans and orangutans share about 97% of their DNA. This is much less than humans and chimpanzees which share 99% of their DNA.
Therefore, the statement that humans are more closely related to orangutans than chimpanzees is an incorrect statement.
