interferons function to make cells a. resistant to phagocytosis. b. lyse when exposed to virus. c. non-motile when infected with virus. d. resistant to viral infection.
Answers
Interferons function to make cells resistant to viral infection. Therefore the correct answer to this statement is option D which is resistant to viral infection.
Interferons are distributed as cytokines, small proteins that are involved in intercellular signalling. Interferon is buried by cells in response to stimulation by a contagion or other foreign substance, but it doesn't directly inhibit the contagion’s addition. Rather, it stimulates the infected cells and those near to produce proteins that help the contagion from replicating within them. The further product of the contagion is thereby inhibited and the infection is stemmed. Interferons also have immunoregulatory functions that inhibit B- lymphocyte( B- cell) activation, enhance T- lymphocyte( T- cell) exertion, and increase the cellular- destruction capability of natural killer cells.

Different cells use different transcription units. Different cells use different polyadenylation sequences. Different cells splice the same transcript differently. Different isoforms are produced. Different cell types make the same protein. The following statement is true.
Different cells use different transcription units, which are regions of DNA that are transcribed into RNA molecules. Different cells also use different polyadenylation sequences, which are the sequences of RNA that signal the addition of the poly(A) tail during mRNA processing. Additionally, different cells can splice the same transcript differently, resulting in different mRNA isoforms. These different mRNA isoforms can produce different protein isoforms, or meso forms, which have slightly different amino acid sequences and functions. Despite these differences, different cell types can still make the same protein, as long as they share the same coding sequence in the mRNA.

what is the difference between primary and secondary succession? provide an example of a place that is or has undergone primary succession. provide an example of a place that is in or has undergone secondary succession.
Answers
A community can develop in an area that is virtually lifeless and devoid of soil through a process called primary succession. A disturbance that wipes out a community without harming the soil is followed by secondary succession.
A climax community is produced by primary succession, whereas a destroyed community is produced by secondary succession. While secondary succession begins with an existing plant community, primary succession begins with bare rock.
Primary succession occurs in a location that has never before been home to a community. Newly exposed rock areas, sand dunes, and lava flows are examples of places where primary succession takes place.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.

Drag each label to the correct location. claire had a heavy breakfast early in the morning. then she went to the gym to exercise. after the gym, claire went to class. while exercising, the body requires a continuous supply of energy and uses up blood sugar at a faster rate. how will hormones maintain the sugar balance in the body from breakfast until claire has lunch? high blood sugar secretion of glucagon secretion of insulin glycogen breaks down to glucose
Answers
As per the question, after breakfast > high blood sugar > pancreas > secretion of insulin > intake of sugar by liver cells. Also, blood sugar low > pancreas > secretion of glucagon > glycogen breaks down to glucose.
The body has to maintain the glucose levels within its limits so, it will undergo the following transitions:
After Claire had breakfast, her blood glucose level will rise. This will stimulate the pancrease to secrete insulin. Insulin will trigger the liver cells to absorb sugar and store it temporarily in the form of glycogen. The result would be that the blood glucose levels of Claire would drop to normal range.
After Claire has exercises in the Gym, her body would consume glucose. Low blood sugar would stimulate pancreas to secrete Glucagon now. Secreted glucagon would now trigger the liver cells to break down glycogen so as to produce glucose. Thus, the blood glucose levels would be regulated to normal.

Where does the ocean get most of its heat?
Answers
Answer:
The ocean gets most of its heat from the following sources:
Solar radiation: The sun is the primary source of heat for the Earth's surface and its oceans. The ocean absorbs sunlight, which warms the surface water and causes it to evaporate. The evaporated water then rises into the atmosphere and eventually falls back to the Earth as precipitation.Atmospheric heat transfer: The atmosphere also plays a role in transferring heat to the ocean. Heat is exchanged between the atmosphere and the ocean through convection, conduction, and radiation. Warmer air can transfer heat to the ocean's surface, while cooler air can absorb heat from the ocean.Geothermal energy: Heat is also generated within the Earth's crust due to the decay of radioactive elements. This geothermal energy can transfer to the ocean through underwater vents and hot springs.Ocean currents: The ocean's currents transport heat from one part of the ocean to another. Warm ocean currents, such as the Gulf Stream, can transport warm water from the tropics to higher latitudes.Overall, solar radiation is the primary source of heat for the ocean, but all of these factors contribute to the ocean's overall heat budget.
Answer:
SunlightExplanation:
Sunlight is the primary source of ocean heat. In addition, heat that has been collected by clouds, water vapor, and greenhouse gases is released, and part of that heat energy reaches the ocean. Heat is continually transferred from warmer to colder latitudes and to deeper layers of the ocean by waves, tides, and currents.
Action potentials are ____________ and postsynaptic potentials are _____________ chemical; electrical all-or-none; graded all-or-none; all-or-none graded; all-or-none
Answers
Action potentials are electrical and all-or-none, while postsynaptic potentials are graded and chemical.
These two types of potentials are fundamental in the process of neuronal signaling. Action potentials are brief electrical signals that are generated and propagated by excitable cells such as neurons. They are initiated by depolarization of the membrane potential beyond the threshold level, causing the opening of voltage-gated sodium channels that let in Na+ ions, depolarizing the membrane further and creating a positive feedback loop.
This rapid depolarization causes the voltage-gated potassium channels to open, allowing K+ ions to flow out of the cell and repolarize the membrane. The net result is a brief depolarization and repolarization of the membrane potential that propagates down the axon to the next neuron or target tissue. The amplitude and duration of an action potential are constant and all-or-none, meaning that it either happens completely or not at all.
Postsynaptic potentials, on the other hand, are changes in the membrane potential of the postsynaptic neuron caused by the binding of neurotransmitters to receptors on the postsynaptic membrane. They are graded, meaning that their amplitude is proportional to the amount of neurotransmitter released by the presynaptic neuron.
There are two types of postsynaptic potentials: excitatory postsynaptic potentials (EPSPs) and inhibitory postsynaptic potentials (IPSPs). EPSPs depolarize the postsynaptic membrane and make it more likely to generate an action potential, while IPSPs hyperpolarize the membrane and make it less likely to fire. The net effect of these postsynaptic potentials determines whether the postsynaptic neuron will fire an action potential or not.
In conclusion, action potentials are electrical and all-or-none, while postsynaptic potentials are graded and chemical. Both types of potentials are necessary for the proper functioning of the nervous system and the transmission of signals between neurons.

Answers
The answer is (d) consumption; 32.
Consumption efficiency is the proportion of available biomass at one trophic level that is consumed by the next trophic level. In this case, the consumption efficiency can be calculated as:
Consumption efficiency = (Amount of biomass consumed by herbivores / Total plant biomass) x 100
Plugging in the given values, we get:
Consumption efficiency = (320 kg / 1,600 kg) x 100 = 20%
Assimilation efficiency, on the other hand, is the proportion of consumed biomass that is assimilated by the consumer. Since the question doesn't provide information on how much of the consumed biomass is assimilated, we can't calculate assimilation efficiency.
