why does decompression melting occur
Answer:
Explanation:
Decompression melting often occurs at divergent boundaries, where tectonic plates separate. The rifting movement causes the buoyant magma below to rise and fill the space of lower pressure. The rock then cools into new crust.
Fish lice live on host fish as a parasite. The fish lice feed on the blood and other fluids in
the fish. What is the likely outcome for the consuming parasite living on a host?
A the host eats the parasite
B the parasite dies and the host lives
Cthe parasite and the host live symbiotically
D the host dies and the parasite finds another host
Answer:
D
Explanation:
It attaches to its host, usually a fish, via its suction cups, pierces the skin with its sharp stylet, and feeds on blood. It may live in the gills.
This cell organelle helps organisms maintain homeostasis by controlling what substances may enter and leave the cells

The Hardy-Weinberg equilibrium can be useful to discover the presence of evolutionary forces acting on a given population. It is used in population genetics.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium is a theory stat states that genotypic and allele frequencies will remain constant in a population in absence of different evolutionary forces.
These evolutionary forces include mutation, natural selection, migration and sample size.

How are amino acids assembled during translation? explain the process of transcription
Answer:
During translation,ribosomal subunits assemble together like a sandwhich on the strand of mrna where they proceed to attract trna molecules tethered to amino acids a long chain of amino acids emerges as ribosome decodes the mrna sequence into polypepide or a new protein.
Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein).
Answer:
Amino acid leads through a chain protein that makes its way into the Ribosome-(in the large subunit)
Explanation:
Check your understanding. What did you include in your response? Check all that apply.
mRNA attaches to the ribosome.
tRNA molecules transport amino acids to the ribosome.
Anti-codons and codons match up and form complementary base pairs.

which of the following is an example of static stretching exercise
Answer: These are the options.
A. Calf
B. Chest
C. Upper Back

Which of these describes one way that the human nervous system maintains a constant body temperature when the external temperature is cold?
A. The Nervous system increases perspiration
B. The nervous system causes digestion to speed up
C. The nervous system causes bloods vessels to construct
D.The nervous system triggers the flight-or-flight response
Answer:
A
Explanation:
Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.Apr 15, 2018
The nervous system causes blood vessels to constrict. Therefore, option (C) is correct.
What is nervous system?When the external temperature is cold, the human nervous system works to maintain a constant body temperature through a process called thermoregulation. One way this is achieved is by causing blood vessels near the skin to constrict, reducing blood flow to the skin and helping to retain heat within the body's core. This response is known as vasoconstriction.
Vasoconstriction is controlled by the sympathetic nervous system, which is part of the autonomic nervous system. This system is responsible for controlling involuntary bodily functions, including heart rate, blood pressure, and body temperature. When the body's core temperature drops, the sympathetic nervous system activates and causes the blood vessels to constrict, helping to maintain a constant internal temperature.
Increasing perspiration (A) can help to cool the body down in hot conditions, but it is not a mechanism for maintaining body temperature in cold conditions. Digestion speeding up (B) and the flight-or-flight response (D) are not directly related to temperature regulation.

A liquid thermometer and an electronic thermometer are both properly placed in the same liquid. The liquid thermometer shows 53.4 degrees Celsius and the electronic thermometer shows 58.2 degrees Celsius. Which could best explain why they show different readings?
Answer:
The correct answer would be - electronic thermometer was not calibrated correctly
Explanation:
Every electronic equipment or instrument like an electronic thermometer, that measures something needs to be calibrated with a standard measurement or reference value to a new measuring device to establish a relationship.
Liquid thermometer measures based on the liquid's actual physical properties, that are present inside it so, calibration is not required.
Thus, the electronic thermometer was not calibrated correctly.

Which process is shown in the image?
A. Passive transport
B. Endocytosis
C. Exocytosis
D. Active Transport
Answer:
Explanation:
Endocytosis
The process shown in the image is of Endocytosis. It is a type of cellular transport through which different substances enters the cell. Thus, the correct option is B.
What is Endocytosis?
Endocytosis is a process during which substances are brought inside the cell. The materials which are to be internalized are first surrounded by the plasma membrane. The plasma membrane in-folds across the substances to form a vesicle.
The vesicle formed by the in-folding of the plasma membrane then fuses with the membrane and buds off into the cell. Thus, the substance are delivered inside the cell.
Endocytosis is of two types- pinocytosis (cell drinking) and phagocytosis (cell eating). Examples of endocytosis includes uptake of cholesterol-bound low density lipoproteins, and recycling of iron-bound transferrin, etc.
Therefore, the correct option is B.

supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?
Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.
