Which statement accurately describes calories and Calories? A kilocalorie is equal to 1000 Calories. A kilocalorie is equal to 1000 Calories. A Calorie is equal to 100 calories. A Calorie is equal to 100 calories. A calorie is equal to 1000 Calories. A calorie is equal to 1000 Calories. A Calorie is equal to a kilocalorie. A Calorie is equal to a kilocalories.
Answer:
A kilocalorie is equal to 1000 Calories.
Explanation:
This is because 1000 calories make kilocalorie and it is the unit of energy in nutrition. It is the energy needed to raise temperature of 1 litre water to one centrigade or Celsius at sea level or is the amount of energy needed to cause increase of one degree Celsius of water.
What might happen to a desert biome if the area received more rain than it normally receives over an extended period of time? Describe some of the changes that you might expect to see
Answer:
Desert biome will change.
Explanation:
Desert biome will change if the area received more rain than normal it receives over an long period of time because the vegetation on that area appears. The change in rainfall pattern in the desert area changes the animals present in this region because the temperature of the desert is no longer suitable for the desert animals so they migrated and other organisms come to this place.
Mitchell's family has the unusual trait of having an extra finger. Many members of his family were with an extra finger, which is a recessive trait. a family dinner, Mitchell's grandmother helped him sketch a pedigree of the family. Dark-shaded family members were born with an extra finger. No shading indicates people who do not have an extra finger. A question mari means it is unknown. Mitchell is #8 on the pedigree and grandmother is #2. Based on the pedigree what do you predict members number 12 number 11 and 13.

What environmental factor in the soil affects the coloration of a hydrangea plant?
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.

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.

What impacts carbon footprint of food
Answer:
Thus, one kg of wheat, or one kg of beef, have different carbon footprints, since their life cycles are different, emitting specific types and varying amount of greenhouse gases. The further along the chain the food loss occurs, the more carbon intensive is the wastage.

Sophie visited Carlsbad Caverns with her family during her summer vacation, and she was amazed at the cave’s formations. She learned that the cave was formed from minerals.
Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.

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.

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]
