Would photosynthesis rates change with the
changing of the seasons? If so, how would
Co2 levels change because of that?
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. ... As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most.
Explanation:
Which of the following is a possible path for carbon to cycle through an ecosystem?
1. Atmospheric CO2 -> animals -> factories -> fossil fuels -> plants
2. Atmospheric CO2 -> factories -> fossil fuels -> animals -> plants
3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories
4. Atmospheric CO2 -> fossil fuels -> factories -> animals -> plants
Answer: 3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories
Explanation:
The carbon cycle is one of the types of biochemical cycles in which carbon is recycled in atmosphere, biosphere, lithosphere, and hydrosphere in various forms. The atmospheric carbon dioxide is absorbed by the plants and they utilize it as reactant for the process of photosynthesis in which they synthesize their own food. These plants are consumed by animals further when these plants and animals die their remains form fossil fuels deep beneath the earth crust. It takes about millions of years for fossil fuels to form in the sedimentary rocks. The fossil fuels are utilized by the factories to run their machines. Again when fossil fuels burn they emit carbon dioxide gas in the atmosphere.

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

The diagram is a heat map to show the fluctuations in temperature.
What are heat maps?A heat map is a type of data visualization that displays a phenomenon's size in two dimensions using colour. The reader will receive clear visual clues about how the occurrence is clustered or fluctuates over space from the fluctuation in colour, which may be by hue or intensity. The cluster heat map and the spatial heat map are two fundamentally distinct types of heat maps. In a cluster heat map, magnitudes are arranged into a matrix of fixed cell size, where the rows and columns represent discrete phenomena and categories. The sorting of the rows and columns is deliberate and somewhat arbitrary, with the intention of suggesting clusters or depicting them as they are identified through statistical analysis.According to the diagram, both land and sea temperatures were higher than usual.

Doctors found out that you are suffering from a serious disease that can only be cured using stem cell therapy. The doctors explain that both adult and embryonic stem cells can be used in your case. Which of the 2 types would you prefer and why? Use facts about each to support your answer.
Answer:
embryonic stem cells
Explanation:
I prefer embryonic stem cells instead of adult stem cells because embryonic stem cells can be differentiate into any cell type whereas adult stem cells can't be differentiated into other cell type. Due to this feature of embryonic stem cells, it can be used for the therapy and the disease can be cured with the help of these embryonic stem cells. So I prefer embryonic stem cells due to their unique ability of differentiation into any type of cell.

Cows have an incredible digestive system which is highly evolved to process grass in unique ways. Please research and write a short essay regarding the function of the 4 bovine stomachs and how they all work together to process complex carbohydrates. Be sure to include the function of the reticulum, rumen, omasum, and abomasum.
Answer: Ruminants have complex digestive system.
Explanation:
Rumen: It is a sac like structure and first region of the stomach of the cow. It is connected with the esophagus. It forms the storage of the food and convert the food in the form of ball called cud.
Reticulum: It is a honeycomb like structure. It is attached with rumen. It holds and stores the heavy and dense components of the food.
Omasum: It lined with folds of tissues. It absorbs water and nutrients form the food.
Abomasum: It is called true stomach as it operate similar to non-ruminant animals. It secretes hydrochloric acid and enzymes to break down and help in feeding food.

What type of succession starts with some soil but then goes through the 10p
steps of succession?
A. Primary Succession
B. Secondary Succession
C. Climax Community
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]
Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.
The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]
It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.
Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]
