why are fossil fuels considered finite?
Answer:
A finite resource is something that can only be consumed once without possibility of being recycled for re-use. Because fossil fuels are burned, they cannot be reused and are therefore a finite resource.
Explanation:
from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.
State a technology and
explain how it is used to
forecast a future event.
I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.

anyone help please
need answer immediately
Answer:
1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.
2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.
3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.

Answer:
Since iguanas are cold blooded animals and can not regulate their own body temperatures, once temperatures reach 40° they become immobilized and they cant move, so if it is cold they will die.
Carolyn observed a freshwater plant, Elodea, in a small aquarium filled with freshwater on her desk. In one five-minute period, Carolyn counted 32 bubbles that formed on the plant’s leaves and were released into the water. She then moved the aquarium from her desk to a sunlit window and observed the Elodea again. In a second five-minute period, Carolyn observed 194 bubbles form and be released by the Elodea into the water.
a. Explain how the bubbles released by the Elodea signify that the plant is cycling matter. Provide evidence to support your answer.
Hello there! Photosynthesis
Objectives:
(Adaptable to grade levels 6-9)
The student will:
1. Observe evidence of photosynthesis in a water plant.
2. Assemble the equipment needed to measure the rate of photosynthesis in
elodea (water plant).
3. Count bubbles of oxygen gas given off by elodea to determine the rate of
photosynthesis.
4. Change the conditions of photosynthesis by altering light intensity and
carbon dioxide amount, and determine the effects on the photosynthesis rate.
5. Prepare a graph of the collected data and analyze it.
Materials Needed:
(For each group of four students)
elodea (water plant) lamp (40 watt)
test tube razor blade (single-edge)
dechlorinated water (room temperature) tape
sodium bicarbonate powder (baking soda) clock or timer
metal stand with rod or test tube rack metric ruler
Strategy:
PART A. Setting Up the Experiment
1. Obtain a sprig of elodea. Remove several leaves from around the cut end of
the stem. Slice off a portion of the stem at an angle and lightly crush the
cut end of the stem.
2. Place the plant into the test tube, stem end up, filled with water.
3. Secure the test tube to a metal stand with tape or place the test tube in a
test tube rack.
PART B. Running the Experiment
1. Place a 40 watt lamp 5 cm from the plant. After one minute, count and
record the number of oxygen bubbles rising from the cut end of the stem.
Count bubbles for five minutes. If bubbles fail to appear, cut off more of
the stem and recrush.
2. Run a second five-minute trial. Record and average your results.
3. Move the lamp so it is 20 cm from the plant. After one minute count and
record bubbles for two five-minutes trials. Again, average and record your
results.
4. Add a pinch of sodium bicarbonate powder to the test tube. Place the lamp
5 cm from the test tube. After one minute, record bubbles for two five-
minute trials. Average and record your results.
5. Prepare a graph of your results. Use the average number of bubbles for the
vertical axis. Use the type of environmental condition for the horizontal
axis.
Performance Assessment:
The students will answer these questions using specific values from the
investigation. Diagrams may be included.
1. How does this investigation demonstrate that plants give off oxygen during
photosynthesis? Explain your answer based on your observations.
2. How does the rate of photosynthesis change when the light source is moved
from a distance of 5 cm to 20 cm?
3. How does the rate of photosynthesis change when sodium bicarbonate is added
to the water?
Conclusions:
Plants use green pigments called chlorophylls to trap light energy. The
chlorophylls give a plant its green color. Inside the cells that have
chloroplasts, the light energy is used to make a simple sugar called glucose.
The process by which plants use light energy to make glucose is called
photosynthesis.
During this process of sugar production, carbon dioxide combines with water to
form glucose and oxygen is released. Oxygen that is produced in photosynthesis
is given off as a gas. If a lot of oxygen is being given off, photosynthesis is
occurring rapidly. If little oxygen is being given off, photosynthesis is
occurring slowly. The amount of trapped light energy and the amount of carbon
dioxide available affects the rate of photosynthesis.
The purpose of adding sodium bicarbonate powder to the water increases the
amount of carbon dioxide in the water.
This investigation can be performed with water plants grown in many parts of
the world, except regions that have permanent ice.
Return to Biology Index
The bubbles released by the Elodea signify that the plant is cycling matter because:
carbon is being fixedoxygen is being releasedCarbon in the form of carbon dioxide is being fixed in the Elodea through the process of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
During respiration by the same Elodea, the carbohydrate produced would be broken down in a reaction with oxygen to produce carbon dioxide and water:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
Thus, important materials such as carbon and oxygen are being recycled in the photosynthetic process.
