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.

Answers
Answer: c. 50%
Explanation:
If you draw a punnett square you see that the phenotypes you get are Cc, Cc, cc, and cc. If C (curly hair) is dominant over c (straight hair) then those with the phenotype Cc would have curly hair and those with the phenotype cc would have straight hair. 2 out of 4 have Cc (curly hair) so that's 50%.

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.

How can we control bacterial diseases? Write any three measures to prevent What are
bacterial transmission.
Answers
Answer:
Bacterial diseases are treated with antibiotics. Antibiotics work by killing the harmful bacteria or by stopping them from reproducing and spreading. Different types of antibiotics are effective for treating specific types of bacteria.
Measures to take
1)Always keep your hands clean.
2)Follow tips for Coughing and sneezing without contaminating.
3) Avoid touching your nose, eyes and mouth with unwashed hands.
Bacteria are transmitted to humans through air, water, food, or living vectors. The principal modes of transmission of bacterial infection are contact, airborne, droplet, vectors, and vehicular. Preventive measures have a dramatic impact on morbidity and mortality.
I hope this helps a little bit.
2) there are a lot of ways for example:
-Wash your hands before eating, or touching your eyes, nose or mouth.
-Wash your hands after touching anyone who is sneezing, coughing or blowing their nose.
-Don't share things like towels, lipstick, toys, or anything else that might be contaminated with respiratory germs.
3) The vast majority of exogenously acquired endoscope-related infections have been caused by bacterial transmission. The bacteria involved have been true pathogens, which always have the potential to cause infection (e.g., Salmonella spp.), or opportunistic pathogens that cause infection if the microbial load is sufficient and/or host-factors are permissive (e.g., Pseudomonas aeruginosa).

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.
Answers
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.

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
Answers
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]

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?
Answers
Answer:
to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
Explanation:
Firstly, let us calculate the number of calories burnt in 2 hours
in 10 minutes; 30 calories are burnt
∴ in 1 minute 30/10 calories are burnt = 3 calories are burnt
2 hours = 120 minute
∴ in 120 minutes 3 × 120 = 360 calories are burnt.
Next, let us calculate the amount of trail mix that contains 360 calories
100g of trail mix = 450 calories
450 calories = 100 g
1 calory = 100/450
∴ 360 calories = 360 × (100/450)
= 360 × 0.222 = 80g
∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

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
Answers
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.
