Why does the word antibiotic suggest that these medications would be ineffective against viruses?
Answer:
Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.
Necrosis is the result of cellular injury that does not allow for cellular adaptation because it is which of the following? (Select all that apply.) Too severe Too prolonged Acute in nature Programmed into the cell itself A result of a disrupted blood supply
Answer:
Too severe
Too prolonged
Acute in nature
Explanation:
Necrosis is can lead to death of a cell, it results from external damage to cell such a s diseases and infection.
Necrosis will not allow other cellular activities because its is acute, any cell affected by necrosis will die premature leading to stop of activities on the body part.
Necrosis is a prolonged sickness that takes a long time, it may require the removal of the dead cell for rejuvenation of new body cells.
Therefore, a damage to Because will not allow for cellular adaptation in that part of the body as it leads to the death of the cell.

How would siamangs be affected if the rain forests they live in produced less fruit? Explain your reasoning.
Answer:
Siamangs are arboreal,in habitat.They are species of gibbons found in the rain forest. They are skillful at moving among tree branches,their swift movement made them to escape predators.They are very noisy.
These animals are light weight because of light bones.Their head is small and round in shape.They have long arms,longer than the legs.Their body is slim.
75 of their diet is made up of fruits.They are omnivores like human thus they eat plants parts,insects, eggs of small birds etc.
They are endangered species.This is because of rapid deforestation of the rain forest habitats for developments. If 75% of their diet (which is fruits is not available)due to less fruits production, definitely they will be endangered and go to extinction from starvation as other sources of food would not sustain them.

What is a relatively dense aggregation of fishes, squid, and other mesopelagic organisms capable of reflecting a sonar pulse that resembles a false bottom in the ocean. Its position varies with the time of day.
Answer:
Deep scattering layer, DSL
Explanation:
The deep scattering layer (DSL) also known as "deep sound layer", refers to an oceanic deep layer, more or less defined, that reflects sound and that is formed by a wide variety of animals. It is present in almost every ocean. It is produced by the presence of many organisms of different species that can disperse the sonar waves sent by a sonar equipment.
It was discovered through the ships´ sonar. Whenever they met a layer in which the sound hit, and was often confused with the bottom of the ocean. This is why the DSL is refered to as the "fake bottom".
These animals form layers of not less than 10 meters thick and might easily reach up to 50 meters thick. These layers are often found between 50 and 200 meters deep and can be seen going up and down every day according to the daily vertical migration.

A population of bacteria sees an increase in the number of bacteria resistant to a certain antibiotic over a number of generations. This is known as ______________.
Answer: MICROEVOLUTION
Explanation: Microevolution simply means those changes in the alleles frequencies of an organism over time.
In other words,we will say that microevolution is the generation to generation change in a population's frequencies of alleles.
These changes can occur due to natural or artificial selection,
Gene flow, mutation and genetic drift.
From the question asked,when a population of bacteria sees an increase in the number of bacteria resistant to a certain antibiotic over a number of generations,it is simply known as microevolution.
A microbiologist is attempting to determine the size of a microbial population and has employed several methods. She noticed that the direct count she obtained using a counting chamber and microscope was much higher than her estimate from doing a viable plate count. This discrepancy was encountered during multiple trials. What is the most likely reason for the discrepancy
Answer:
The options are
A. She did not correctly do the serial dilutions to the viable plate count
B. Many organisms viewed during the direct count may be dead
C. The organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism
D. The medium and growth conditions used for the viable count will not support the growth of the organisms
The answer is C. The organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism
Explanation:
The discrepancy encountered during multiple trials which involved noticing that the direct count she obtained using a counting chamber and microscope was much higher than her estimate from doing a viable plate count was most likely as a result of the organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism.

Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
Our current understanding of evolution is called a theory because it has been supported repeatedly as new discoveries have been made. proven to be exactly true as originally proposed. corroborated by data that were gathered during a single experiment. developed from the postulates of many scientists.
Answer:
supported repeatedly as new discoveries have been made.
Explanation:
Evolution is called a theory yes this is a true statement as a theory can be changed ad it has records of evolution.
Scientists communicate approximately evolution as a theory, for instance, simply as they communicate approximately Einstein's rationalization of gravity as a theory. A theory is a concept approximately how something in nature works that have long gone thru rigorous checking out thru observations and experiments designed to show the concept proper or wrong. What is evolution?Evolution is a technique that affects adjustments withinside the genetic content material of a populace over time. There are trendy instructions for evolutionary change.

On an annual basis, what is the net result of the contributions/removals of CO2 from the atmosphere due to global photosynthesis and respiration
Answer:
The correct answer is : approximately 3 gT yr^-1 decrease
Explanation:
Carbon dioxide is contribute and removed from the atmosphere by various type of activities that are human activities, biological input or biological removal and geological input or geological removal.
Adding carbon dioxide can be from biological inputs mainly respiration and removed from atmosphere mainly through biological removal mainly photosynthesis.
Both photosynthesis are complementary metabolic process that play major role of adding and removal of carbon dioxide. There is a decrease of 3gT yr^-1 approximately on the annual basis due to these biological process.

Formed elements in blood are ______, and plasma is _______. Select one: a. blood clots; proteins b. mostly lipids; the matrix c. the cells; the liquid portion of blood d. lacking in protein; regulator of blood osmolality e. acellular; cellular
Answer:
option A is correct
Explanation:
Formed elements in blood are blood clots and plasma is proteins. Hence option a is correct.
What is blood?Blood is defined as a fluid that circulates regularly and gives the organism nutrients, oxygen, and waste elimination. Blood is pumped into the pulmonary arteries in the lungs from the right ventricle after entering the right atrium from the body. After absorbing oxygen, the blood returns to the heart through the pulmonary veins, passing through the left atrium, left ventricle, and aorta before leaving the body through the tissues.
In plasma, there are 8% to 9% solids and 91% to 92% of water. It primarily consists of: Blood clotting is aided by coagulants, particularly fibrinogen. Albumin and globulin are two plasma proteins that contribute to keeping the colloidal osmotic pressure at 25 mmHg.
Thus, formed elements in blood are blood clots and plasma is proteins. Hence option a is correct.

Which hormone is essential to our ability to maintain our fluid levels? Which hormone is essential to our ability to maintain our fluid levels? cortisol thyroxine insulin aldosterone
Answer:
Aldosterone.
Explanation:
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.

Answer:
Explanation:
Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus,[2] and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. All these related species are now sometimes collectively termed australopithecines or homininians.[3][4] They are the extinct, close relatives of humans and, with the extant genus Homo, comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina[5] (see Hominidae; terms "hominids" and hominins).
While none of the groups normally directly assigned to this group survived, the australopithecines do not appear to be literally extinct (in the sense of having no living descendants) as the genera Kenyanthropus, Paranthropus and Homo probably emerged as sister of a late Australopithecus species such as A. africanus and/or A. sediba.
The terms australopithecine, et al., come from a former classification as members of a distinct subfamily, the Australopithecinae.[6] Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines".[7][8]
The australopithecines occurred in the Plio-Pleistocene era and were bipedal, and they were dentally similar to humans, but with a brain size not much larger than that of modern apes, with lesser encephalization than in the genus Homo.[9] Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines.[8]
The generation of radioactive wastes such spent (used) reactor fuel, uranium mill tailings, and other radioactive wastes is a significant environmental hazard associated with nuclear power.
What impact of nuclear power, energy on the environment?Nuclear energy is still readily available, despite the fact that it isn't strictly renewable (since there is only a finite amount of uranium on Earth).
Additionally, even though using nuclear energy to produce electricity is a carbon-free process, building new nuclear energy facilities and mining the uranium fuel have their own environmental consequences.
For millions of years, these substances may continue to be radioactive and hazardous to human health. The trash that nuclear power generates is the most urgent environmental concern.
During the course of a nuclear power plant's operation, a few different types of radioactive material are created, most notably used reactor fuel and the tailings from uranium mills.
Therefore, These pose numerous risks to the health of both people and the environment if they are not handled and disposed of properly.

Explanation:
A stroke victim has great difficulty moving his right hand and right leg. He also has trouble speaking. Which of his cerebral hemispheres is most likely to have been damaged
Answer:
The correct answer is left cerebral hemisphere.
Explanation:
The left cerebral hemisphere of the brain is accountable for the motor control of the right side of the body, for sensory stimulus from the body’s right side, for analysis and calculations, for the speech, comprehension, and language, for the recognition of letters, words, and numbers, and for time and sequencing.
The left cerebral hemisphere is accountable for the processing of the sensory information and motor information for the body’s right side. Thus, as left cerebral hemisphere monitors the movement of the body's right side, so, based on the extremity of the stroke, which may result in motor skill impairment or functional loss of the right side of the body, shows that the left side of the brain has got affected.
The cerebral hemisphere most likely damaged in this person is the LEFT hemisphere.
The cerebrum can be divided into two major hemispheres known as the right and left cerebral hemispheres.The left cerebral hemisphere is involved in the control o the right side of the body. This hemisphere (left hemisphere) is associated with science and/or mathematical skills, language functions (e.g., grammar, vocabulary), etc.In conclusion, the cerebral hemisphere most likely damaged in this person is the LEFT hemisphere.
