I believe that the answer you are looking for is letter D, 11.0 grams/milliliter.
Solution/Explanation:
Writing out the formula for the density, using mass and volume,
D=m/v
Substituting the given values of the variables,
D=33.0 grams/3.0 milliliters
33÷3=11.
So, therefore the final answer is the letter D, 11.0 grams/milliliter.
I hope that this has helped you. Enjoy your day, and take care.
Which statement about human population growth is FALSE?
a) From 1350 AD to the present, the world has experienced continuous population growth.
b) From 200,000 BC through 8,000 BC, the global population was low.
c) The global population is expected to peak at 7 billion, then begin decreasing.
d) The world population doubled between 1959 and 1999.
Which statement about human population growth is FALSE?
Choose: c) The global population is expected to peak at 7 billion, then begin decreasing.
The false statement is: The global population is expected to peak at 7 billion, then begin decreasing.
What is meant by population growth?
Population growth is the increase in the number of humans on Earth. For most of human history, our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable.
Was there population growth in 2020?Population gains attributable to natural increase rose as high as 1.1 million in 2016-17, but dropped to 677,000 in 2019-20 and then again to 148,000 in 2020-21.

Based on graph 1, do you think the changes in solar intensity are a significant cause of the trend in global temperatures? Why or why not?
Answer:
Changes in solar intensity do not seem to contribute to the change in global temperatures. If they did, the temperatures would rise and fall with the Sun's energy. Instead, the global temperatures continue to rise despite the Sun's natural fluctuations.
Explanation:
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland.
No, because the increase in temperature on earth is mainly related to global warming generated by the release of greenhouse gases and the release of CO2 into the atmosphere.
Explanation:
It is by action of man not because of the solar intensity

Chris wrote a few steps to describe how carbon circulates between the ground and living organisms.
Step 1. Trees absorb carbon dioxide in the air and use it to make their own food using photosynthesis.
Step 2. When plants or animals die, they are broken down by decomposers and their carbon returns to the soil.
Step 3. Carbon stays in the ground for long-term storage as fossilized carbon.
If step 1 is removed, which statement best describes the effects of this missing step on the carbon cycle?
More carbon is stored in the ground for long-term storage.
Less carbon is available for plant and animal growth.
More carbon is stored in plants instead of the ground.
There are more fossil fuels available for energy use.
Answer: i think it is less carbon is available for plant and animal growth. if not i'm sorry
The carbon cycle involves the circulation of carbon and its compound in the earth's spheres. Removal of step 1 results in decreased carbon for animals and plants. Thus, option b is correct.
What is the carbon cycle?The carbon cycle is a cyclic movement of carbon in various spheres between the biotic and the abiotic factors. It involves the biosphere, atmosphere, geosphere, and other spheres. Carbon comes from the atmosphere in the form of carbon dioxide.
This carbon dioxide is used by plants to make food in the form of sugar and is consumed by animals as an energy source. If trees utilizing carbon dioxide are removed then less carbon will be available for cellular respiration.
Therefore, option B. removal of step 1 from the process results in less availability of carbon from animals and plants.

What can happen to solar radiation when it enters Earth’s atmosphere?
It is increased as it hits the clouds.
It is absorbed or reflected as it travels to Earth’s surface.
It is changed into visible light.
It is destroyed by the water molecules in the atmosphere.
Solar radiation is absorbed or reflected as it travels to the earth's surface.
Solar RadiationWhen solar radiation enters the earth's atmosphere, the rays travel and hit the ground.
Some of the rays are absorbed by the ground while the rest are reflected back to the atmosphere.
Some of the reflected rays are absorbed by a layer of gas (greenhouse gases) that forms a blanket in the atmosphere while a tiny portion returns back into space.

How do moon jellies obtain energy?
Answer:
Like all true jellies, the moon jelly's tentacles are covered with specialized stinging cells, called cnidocytes. ... They have very little nutritional value, however, so the predators that specialize on them must eat hundreds and hundreds of these jellies in order to maintain their required energy levels. Moon jellies stay close to shore, and they pulse their bell to keep themselves near the surface, with their tentacles pointed down. This ensures they can gather as much food as possible. They gather food when it gets stuck in the mucus along the bottom of the bell.
Hope this helps <3 PMB (plz mark brainliest)
Answer:
While it might be nice to grow the missing part back, doing so takes a lot of energy that simply may not be available. For the moon jelly, it takes less energy to simply rearrange the parts in its gelatinous body into a new symmetrical and hydrodynamically efficient configuration and keep moving along on its journey.

By performing photosynthesis, plants create everything they need to build all biomolecules. Is
this true? Why or why not? (1 point)
This is true because photosynthesis produces glucose, and plants only need
sugars, not amino acids or fatty acids.
This is not true because plants need to sequester nitrogen from the soil to
build amino acids.
This is true because photosynthesis produces glucose, which has carbon,
hydrogen and oxygen-the building blocks for all biomolecules.
This is not true because plants need to perform cellular respiration to break
down the glucose into carbon, hydrogen, and oxygen.
Answer:
This is not true because plants need to sequester nitrogen from the soil to build amino acids.
Explanation:
This is the answer i got on my quiz
This IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.
Carbon (C), Hydrogen (H), and Oxygen (O) are building blocks of carbohydrates. Plants must obtain Nitrogen from the soil, as well as phosphorous (P) and sulfur compounds (among other critical compounds), to sustain life.For example, DNA and proteins, which are critical biomolecules to sustain life, are composed of Nitrogen (N).Amino acids are the building blocks of proteins.In conclusion, the statement above IS NOT true because plants need to obtain Nitrogen from the soil to build amino acids.
