Which organism is an autotroph?
fox
squirrel
tree
fungus
Answer:
The tree is the autotroph.
Explanation:
First, let's define what autotrophs are.
Autotrophs are organisms that make their own food, not relying on other organisms to eat.
Now let's explain why trees are the answer.
Trees use photosynthesis to make their own foods in the form of glucose (or sugar). The plant then uses these to sustain themselves. This process makes them an autotroph.
Answer:
Pretty sure its a tree, an autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. which would be a tree
The capacity for _______________ protects us in daily life from being overwhelmed by all the sensory signals impinging on our receptors.
Gene investigated the effect of moisture on the rate of growth of mold on bread. He put two identical slices of bread on separate plates. He made one slice moist and kept the other slice dry. He left the uncovered plates on a table for 2 hours. Then, he sealed them in plastic bags and put them in a dark, warm place. He looked at them each day for five days. After five days, he observed that 50 percent of the moist slice was moldy, and none of the dry slice was moldy. If Gene observed the slices for three more days, what would he most likely observe?
There would be less mold on the moist slice. There would be more mold on the moist slice. There would be the same amount of mold on each slice. There would be no change in the amount of mold on either slice
Answer:
More mold on the moist slice
Explanation:
Assuming that the trend continues, then after another 3 days, a higher percentage (more than the original 50%) of mold will be found on the moist slice, while the dry slice may either be unaffected or may develop very little mold.

Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called _____.
Answer:
Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called nondisjunction.
Explanation:
Answer:
Nondisjunction
Explanation:
Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during mitosis or meiosis. This leads to daughter cells with unequal amounts of DNA. In fetuses in particular, this type of accident can have extreme consequences, such as the birth of a child with Down's Syndrome or a premature death.

In 3 to 5 sentences, analyze potential impacts of oceans on human populations as the result of climate change in the current century
Answer:
Due to continuous global warming, the oceans tend to gain more heat, and hence the temperature rises. In the current century, the heated conditions of the oceans can be threatful for the human population. Also, the increase in the sea levels will have serious consequences on the health of mankind and their quality of life.
Explanation:
As the overabundance heat and energy warms the ocean, the temperature change causes unprecedented cascading effects such as ice melting, sea-level rise, marine increased temperatures, and ocean acidification.
What is ocean acidification?The massive quantity of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.
This is known as ocean acidification, and it is literally causing a sea change that is threatening the basic chemical balance of ocean and coastal waters from pole to pole.
Changing ocean chemistry, according to laboratory studies, will
Harm life forms that rely on carbonate-based shells and skeletons, Harm organisms which are usually sensitive to acidity.Harm organisms in higher tropic levels of the food chain that feed on these sensitive organisms.As the ocean warms due to an abundance of heat and energy, the temperature change causes unprecedented cascading effects such as ice melting, sea-level rise, increased marine temperatures, and ocean acidification.
Thus, the human population can be widely affected as a result of impacts of climate changes.

why is the composition of oxygen in the alveoli lower than the composition of oxygen in the atmosphere?
Answer/ Explanation:
The respiratory system works to humidify incoming air, thereby causing the air present in the alveoli to have a greater amount of water vapor than atmospheric air. Alveolar air contains a greater amount of carbon dioxide and less oxygen than atmospheric air.
A few other reasons are....Alveolar air is partially replaced by atmospheric air during each breath
Oxygen is constantly absorbed into the blood from alveoli
Carbon dioxide is diffused into alveoli from blood
As air enters respiratory passages it becomes humidified diluting the inspired gases' partial pressures

What is one difference between the structure of DNA and RNA?
I will give BRAINILEST
A. DNA is shorter than RNA
B. DNA is a double helix and RNA is a single helix
C. DNA is made of proteins and RNA is made of lipids
D. DNA is a single helix and RNA is a double helix
Answer:
I think it's B (I'm sorry if I'm incorrect)
Explanation:
RNA and DNA differ in three main ways: RNA is single-stranded, while DNA is double-stranded. Uracil is in RNA, while thymine is in DNA. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose.
One difference between the structure of DNA and RNA is DNA is a double helix and RNA is a single helix. The correct option is B.
What are DNA and RNA structure?DNA and RNA, both are the genetic material, both are made up of protein and both structure is spiral.
The major difference in DNA and RNA is DNA is double-helical and RNA is single helical. DNA is found in all animals and plants, but RNA is present in bacteria.
Thus, the correct option is B. DNA is a double helix and RNA is a single helix

how do power plants generate electricity? this is an integrated science question
Coal fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Answer: They provide oxigen to the human society
Explanation:Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.
Photosynthesis takes place in the chloroplasts of plant cells.
True
False
Answer:
True.
Explanation:
The chloroplasts' function is to take energy to perform photosynthesis. That is why there are no chloroplasts in animal cells.
Answer:
True
Explanation:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
How does the process of photosynthesis support the transformation of energy?.
Answer:
there are two stages of photosynthesis which is the light and dark reaction stage. In the light reaction stage light from the sun is absorbed by the chlorophyll pigments and also split water molecules through a process called photolysis, in this stage light energy is transferred to chemical energy of ATP (adenosine triphosphate) and make reduced NADP (nicotinamide adenosine dinucleotide triphosphate). This stage justifies the second law of thermodynamics which states that the process of energy transformation cannot occur spontaneously unless there is a breakdown of energy from a concentrated form into a dispersed form.
