Varicella-zoster is the virus that causes chickenpox. The average incubation period is 14 to 16 days after exposure. A person usually experiences a mild fever and fatigue for 1 to 2 days before rashes appear all over the body. A person having had chickenpox as a child may have the virus lay inactive in the nerve cells for many years only to reactivate much later as an adult in the form of shingles, which results in a very painful rash. This information suggests that the reproductive cycle of the varicella virus is -
a)lytic for shingles because the virus causes rashes to appear on the skin.

b) lysogenic for chickenpox because the virus attacks the mucous membranes.

c) lysogenic because the virus is a varicella-zoster virus.

d) lytic for chickenpox because the symptoms appear soon after infection.

Imagine two closely related, but separate, species of fish reproduce and the hybrids offspring have higher fitness than either of the parent species. Given enough time, the most likely outcome will be: Group of answer choices The two original species will eventually fuse into a third new species, and disappear. The two original species will remain, and a third new species will appear. Nothing: the two original species will remain, and the hybrids will eventually disappear.

Fish are sensitive to many environmental variables: dissolved oxygen, light, temperature, pH, clarity of water, food supply, presence of predators, etc. Fish will be attracted to different locations in a lake, based on its mix of variables.

Imagine you want to conduct an experiment to understand how just one of these variables differs in a local lake, depending on its depth. This lake reaches a depth of 17 meters. For this activity:

Pick a variable that might change as you go deeper in the lake on a given day.
Do a little research on that variable to determine how you might measure it in a lake.
Use the template below to outline an experiment to investigate this variable in the lake by depth. For each part, simply answer the question in parentheses to create your outline.
Type your response to each field in the space below that field:

Title: (Enter a brief, descriptive title. Hint: Sometimes it’s best to do this last.)

Purpose: (Why are you doing this experiment?)

Hypothesis: (What do you predict from this experiment and why?)

Procedure/Method: (How will you specifically carry out your experiment to test your prediction?)

Observations: (What specifically would you look for and record?)

Data analysis: (With this kind of data, what would be the best way to present it?)

Conclusion: [No need to enter anything here for now.]

References: (List any references you used to design the experiment. Note that for a full experiment write-up you’d also list any references you used while carrying out the experiment or in analyzing your results.)

what are the number of birds in the world.​

Our model includes the fact that as whales dive deep and then come back
to the ocean surface the whales help phytoplankton to move to the
surface' they phytoplankton can use sunlight near the surface to do
photosynthesis.(whales need to come to the surface to breathe air, they
cannot get oxygen from water- they are mammals, not fish!). Explain why
this is important for decreasing the amount of carbon dioxide in the
atmosphere and helps slow climate change.

ey's Bell Jar...
Abstract
Background
Photosynthesis maintains aerobic life on Earth, and Joseph Priestly first
demonstrated this in his eighteenth-century bell jar experiments using mice and
mint plants. In order to demonstrate the fragility of life on Earth, Priestley's
experiment was recreated using a human subject placed within a modern-day
bell jar.
Methods
A single male subject was placed within a sealed, oxygen-depleted enclosure
(12.4% oxygen), which contained 274 Cz and C plants for a total of 48 h. A
combination of natural and artificial light was used to ensure continuous
photosynthesis during the experiment. Atmospheric gas composition within the
enclosure was recorded throughout the study, and physiological responses in the
subject were monitored.
Results
After 48 h, the oxygen concentration within the container had risen to 18.196, and
hypoxaemia in the subject was alleviated (arterial oxygen saturation rose from
86% at commencement of the experiment to 99% at its end). The concentration
of carbon dioxide rose to a maximum of 0.66% during the experiment.
Conclusions
This simple but unique experiment highlights the importance of plant life within
the Earth's ecosystem by demonstrating our dependence upon it to restore and
sustain an oxygen concentration that supports aerobic metabolism. Without the
presence of plants within the sealed enclosure, the concentration of oxygen
would have fallen, and carbon dioxide concentration would have risen to a point
at which human life could no longer be supported.
