Explain how natural forces and human effects affect the observed global temperature (black line) in graph 2. Is solar radiation a natural force or a human effect?
Answer: There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean and land surface to increase.

Explanation:
Hope this helps in anyway,
Worm, Bird, Snakes, Hawks are the order of how the energy flows.
What is Food chain?
Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.
Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy to food by photosynthesis, are the primary food source.
Because energy, in the form of heat, is lost at each step, or trophic level, chains do not normally encompass more than four or five trophic levels. People can increase the total food supply by cutting out one step in the food chain.
Therefore, Worm, Bird, Snakes, Hawks are the order of how the energy flows.

Why do you think the food dye mixed at different rates?
Answer:
The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
Hope this helps!! (Please mark Brainliest if possible!!)
How does energy move in a healthy ecosystem from the sun to the plants and animals?
Answer:
First,the sun transferes heat to the plants,helping them grow.Animals such as deer who would eat grass,eat plants.
Explanation:
Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.
What is energy transfer?
The sun is the principal energy source for practically all ecosystems on Earth. Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The food chain provides the simplest visual representation of this energy transfer.
A new trophic level is represented by each link in the chain, and the arrows depict the flow of energy through the chain. The primary producer is always at the bottom of a food chain. Plants are the most important primary producers in terrestrial ecosystems, whereas phytoplankton is the main primary producer in marine ecosystems. In their respective habitats, each generates the majority of the nutrients and energy required to maintain the rest of the food chain.
Gross primary productivity is the collective term for all the biomass produced by primary producers. After the primary producer has utilized the energy required for respiration, what is left over is what is known as net primary productivity. This is the portion that can be ingested and passed up the food chain by the main consumers.
Therefore, the transfer of energy within the trophic levels results in energy transfer.

Which type of biotechnology would be used by scientists who use the egg cell of an endangered animal to increase the population of the animal?
Genetic engineering because the genes of the animal would be modified
Genetic engineering because it is always helpful for the environment
Cloning because offspring that are exact copies are produced
Cloning because offspring would be produced in a few hours
Answer:
the 3rd option: Cloning because offspring that are exact copies are produced
Explanation:
Biotechnology is a field of science that comprises biology combined with technology. It utilises the living system with the technology to build products.
The correct answer is:
Option C. Cloning because offspring that are exact copies are produced.
This can be explained by:
Cloning is a mode of reproduction in which the replica of the parent is produced as offspring.The genetic content of the offspring is the same as that of the parent. Hence all the traits and the characters remain preserved.Therefore, for deliberately producing the endangered species cloning technique can be employed.

A) How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
B) If there are 80.0 grams of Neptunium-240 (Np-240), how much Neptunium-240 will remain after 4 hours? The half-life of Neptunium-24 is 1 hour.
Answer:
a) 6400 years
b) 5 grams
Explanation:
a) to get 6400 years, the 40 grams is halved 4 times to get to 2.5g and 4 times 1600 is 6400
b) 80 is halved 4 times and the final result you get is 5 grams
80/2= 40/2= 20/2=10/2=5
each divided by 2 represents 1 hour

A scientist lists the characteristics of an organism which he is observing. This organism should be classified under the kingdom Plantae. Thus, the correct option is D.
What is Plantae?The living organisms on the planet are divided into five different kingdoms including Monera, Protista, Fungi, Plantae, and Animalia are classified on the basis of their characteristics such as the cell structure, mode of nutrition, mode of reproduction and the body organization.
Kingdom Plantae is a kingdom of the five kingdom classification given by R. H. Whittaker. Plants include green, brown and red algae, liverworts, mosses, ferns and the seed plants with or without the formation of flowers. They have the characteristics including multicellular organisms, covered with a cell wall made up of cellulose, are autotrophs (make their own food), contain photosynthetic pigment in plastids.
Therefore, the correct option is D.
