Being nocturnal is an adaptation that plants and animals use to deal with water scarcity and dry climate. Which biome is likely to have the maximum number of nocturnal animals? A.Grassland B.Rain Forest C.Coniferous Forest D.Desert
Biomes on Earth have exhibited changes throughout history that have been caused by a variety of factors. Over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation. What factor is likely most responsible for the changes observed in the world’s rainforests?
Human activity is probably most responsible for the modifications witnessed in the world's rainforests.
The humans thrive in the rainforests and affect it extremely. The activities like logging have resulted in the loss of almost 137 animal and plant species each day due to deforestation. The activities of humans like the production of toxic by-products, oil spills, and mining incidents, and the continuous dumping of wastes are endangering the rainforests and the species living in there.
The humans also practice the slash and burn agriculture that then results in infertility of the soils and makes vegetation to stop growing. The lack of plants eventually results in an increase of carbon dioxide in the atmosphere, thus, causing global warming.
A biologist is writing a report about a group of rattlesnakes that all live in the state of Florida. All rattlesnakes in this group can breed with one another and produce offspring that can reproduce together. The report includes statistics about the number of these rattlesnakes, their breeding rate, and the ranges of their sizes and other traits. In this report, the biologist is describing? A.a community in Florida. B.a biome in Florida. C.a population in Florida. D.an organism in Florida.
The correct answer is option C, a population in Florida
The population description is an efficient language is termed as demographics. The descriptive components of the demographics are –
a) Population Size – It gives the number of individuals within a population
b) Population Density – It defines the size of a population with respect to the space occupied by it
c) Age Structure of the Population – It categorizes different individuals in a population group to different age sections
d) Fecundity – It describes about an individual that is able to produce during a given period of time
e) Morality – It gives the death and birth rate of a population

What role does cellular respiration play in the water cycle? It removes H2O from the atmosphere during glycolysis. It removes H2O from the atmosphere during acetyl CoA formation. It releases H2O to the atmosphere during the citric acid cycle. It releases H2O to the atmosphere during electron transport.
The right answer is It releases H2O to the atmosphere during electron transport.
Respiration was defined following Lavoisier's work as a mode of gaseous exchange by which a living being releases carbon dioxide in exchange for an absorption of oxygen.
It is usually the oxygen of the air that intervenes: activated, it will combine with protons to form the metabolic water excreted during breathing in the atmosphere.
All of the following lists include sources of point-source pollution EXCEPT : A) oil spills , irrigation , fertilizers , pesticides B) pesticides , oil spills , irrigation , leaky underground storage tanks C) drainage from industrial plants , oil spills , runoff from street gutters , chemical spills D) pesticides , herbicides , animal waste , irrigation

Select the best description for each cycle: 1.Hydrologic A. photosynthesis and respiration 2.Rock B. erosion, deposition, metamorphism 3.Tectonic C. housed mostly in rock material 4.Carbon D. it's all about water 5.Nitrogen E. subduction, uplift, and mantle convection 6.Phosphorus F. it's all about special bacteria
The right matches are:
1.Hydrologic is matched with D. it's all about water
Hydrology is the science of the earth which is interested in the terrestrial branch of the water cycle, that is to say in the exchanges between the atmosphere, the terrestrial surface and its subsoil. We speak of hydrosphere to designate the part of the planet in which water is located.
2.Rock is matched with B. erosion, deposition, metamorphism
Rocks are natural materials generally solid and formed, essentially or entirely, by an assemblage of minerals, sometimes including fossils (especially in sedimentary rocks), glass resulting from the rapid cooling of a liquid (volcanism, friction .. .) or aggregates of other rocks. The rocks can be formed of a single mineral species (monomeral rocks) or of several (polymineral rocks):
3.Tectonic is matched with E. subduction, uplift, and mantle convection
Tectonics is the study of geological structures of kilometric scale and more, such as mountain ranges or sedimentary basins, and mechanisms that are responsible. This discipline is directly related to plate tectonics.
The lithosphere, the rigid outer shell of the Earth consisting of the crust and part of the upper mantle, is subdivided into plates, called tectonic or lithospheric plates.
4.Carbon is matched with A. photosynthesis and respiration
The 2 main carbon "reservoirs" most directly involved in this cycle are the atmospheric CO2 and the carbon constitutfs of living beings. During photosynthesis, CO2 and water combine (reduction reaction) under the effect of light energy (sun) to form carbohydrates.
Then, in all organisms, these carbohydrates are oxidized to reform water and CO2 during breathing. Part of the energy contained in carbohydrates is converted into ATP. Up to 35% of the CO2 fixed during photosynthesis is released during leaf respiration.
5.Nitrogen is matched with F. it's all about special bacteria
Special bacteria pick up nitrogen and release it in a form that can be assimilated by the plant
To be absorbed by the plant, the nitrogen present in the atmosphere in N2 form must undergo biological transformation processes carried out by microorganisms called nitrogen-fixing bacteria. These nitrogen-fixing bacteria have the main function of capturing the nitrogen present in the air, but also in the soil (thus limiting the losses in the aquifers), and to return it to the plant in an available and assimilable form. Nitrogen in soil is in NO3- form (soil nitrate) and nitrogen in air is in N2 form (atmospheric nitrogen).
6.Phosphorus is matched with C. housed mostly in rock material
Global phosphate mineral resources are estimated at more than 300 billion tonnes in 2014 (US Geological Survey). The largest sedimentary deposits are found in North Africa (Morocco), China, the Middle East and the United States. The exploited phosphorus deposits come mainly from sedimentary or marine deposits, but also magmatic deposits or guano from exotic marine birds.

What is the best explanation for why a cell might shrivel? A, There is less water in the cell than there is water in the environment surrounding the cell. B, There is more water in the cell than there is water in the environment surrounding the cell. C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell. D, The water solution in the environment surrounding the cell has a lower solute concentration than the cell.
The right answer is C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell.
Plasmolysis (the phenomena of shriveling cell) is a cellular state of the plant cell where, following loss of water, the membrane is detached from the pectocellulose wall. This is the opposite state of turgescence.
Plasmolysis occurs when a stream of water comes out of the vacuole and the plant cell through osmosis. The resulting decrease in pressure causes shrivelling of the soft parts of the plant (stems, leaves, petals), which are no longer supported by the turgor pressure.
This flow of water is created either by the lack of water in the external environment, or by the presence in this medium of a liquid more concentrated than the cellular medium. In these situations, there is a displacement of water by osmosis from the cell medium to the external medium.
Thus, the cells of a plant subjected to a drought or a water too concentrated in salts will lose their water and will be in plasmolysis. The soft parts will then shrivel up and the plant will die of water stress if the situation does not allow it to quickly reabsorb water.
In organisms other than plants, when and where is the most ATP produced? in thylakoids, during photosynthesis in nuclei, during cellular respiration in chloroplasts, during photosynthesis in mitochondria, during cellular respiration
Answer: In the mitochondria during the process of cellular respiration.
The food that we intake is in the form of either carbohydrate, fat and proteins. The food needs to be converted in the form of adenosine triphosphate which is used by the cells of the body.
The process of cellular respiration takes place in the mitochondria which is the site for the formation of ATP.
The cellular respiration is the process by which there is a conversion of carbohydrates into ATP.

B)Agriculture causes water pollution when fertilizers and pesticides flow into lakes and rivers. C) Burning fossil fuels causes air pollution by decreasing water vapor in the atmosphere. D)Using radioactive materials causes ground pollution when chlorofluorocarbons (CFCs) seep into the ground
i think it is tundra
Deep-ocean lantern fish have special organs that use chemical energy to produce light. However, the light can only travel a certain distance through the water before it is no longer visible. How does this phenomenon validate the Law of Conservation of Energy? The fish is a closed system, so energy is allowed to exit the system. The Law of Conservation of Energy applies to biological, not physical, systems. The light energy travels through the water until it is reflected or absorbed. The light is not carried by matter and contains no energy.
The correct answer is that the light energy travels through the water until it is reflected or absorbed.
The law of conservation of energy is illustrated as the form of energy that cannot be destroyed or produced, however, it gets transformed from one form to another. In case of Deep Ocean lantern fish that generates light in water, which travels along certain distance and then moves back, that is, in the reverse direction. This happens as the light travels in waves and when it comes in contact with the waves, it either gets absorbed or is reflected back.
!!!!99 POINTS PLEASE HELP!!!! Water flows through the body of the sponge in the direction the arrow points in this illustration. how does water move through a sponge?

D.or in through the spongocoel and out through the pores or in through the spongocoel and out through the pores
The correct answer is in through the pores and out through the osculum
Answer: by absorbing it from soil
Nitrogen is an essential element required by the plants for their growth and metabolism that is for the synthesis of amino acids, proteins, and nucleic acids. The nitrogen is present in the earth atmosphere for about 78%. The plants cannot directly absorb atmospheric nitrogen instead they are capable of absorbing and utilizing the compounds of nitrogen such as ammonia, nitrates and nitrites. The atmospheric nitrogen is absorbed and fix in the soil by soil bacteria into compounds of nitrogen which can be easily absorbed by the plant roots from the soil.
