The statement in the beginning of the question, "scientists have found that although plants require light to carry on photosynthesis Very high levels of sunlight can kill some plants" suggests that there is a certain range of levels of sunlight that plants can survive in. Therefore, only choice B. with a specific range of conditions is supported by the evidence. Hope I could help.
With a specific range of conditions is supported by the evidence is the correct option.
What is photosynthesis?Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it gains electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Both light-dependent and light-independent processes. As suggested by its name, the light-dependent reaction takes place inside the thylakoid membrane and requires a steady stream of sunlight.
Therefore, With a specific range of conditions is supported by the evidence is the correct option.

what are the two factors that create the difference between the temperate forest biome in the taiga biome
The temperate forest biome covers latitudes ranging approximately from the southern United States to southern Canada, while the taiga biome, also known as boreal forest, extends from the latitude of southern Canada to about 60 degrees north latitude. (see References 1, References 3) Thus, these two biomes are adjacent, which explains the many similarities between taiga and northern temperate forests. Both biomes have four distinct seasons, but the temperate forest climates cover a much wider range of temperatures and precipitation patterns. Taiga, in contrast, is reliably cold: most of the precipitation falls as snow, winters are severe and the growing season is short -- about 130 days compared to 140 to 200 days for temperate forests.
The two factors that create the difference between the temperate forest biome and the taiga biome are as follows:
Temperature.Precipitation. What is a biome?A biome may be characterized as a very large ecosystem that is consistently running in nature in an unmanaged way. In more simple words, it is defined as a very large area that is characterized by a particular type of vegetation. Some examples of biome may include tropical rainforests, coral reefs, grasslands, etc.
Taiga biomes are generally thick forests. Coniferous trees, such as spruce, pine, and fir, are common. These trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones.
While temperate forests have deciduous trees which lose their leaves in winter, conifers never lose their needles. All such differences are created by numerous factors but temperature and precipitation are the most potent ones.
Therefore, temperature and precipitation are the two factors that create the difference between the temperate forest biome and the taiga biome.

To see a whole insect under a microscope, you would probably not use a...
A) Compound light microscope
B) Stereoscope microscope
C) Scanning electron microscope
D) Simple microscope
C.) Scanning electron microscope. You would not be able to see a whole insect with one of these.
Hope this helped :)
To observe a whole insect, a Compound light microscope would not be suitable since it's designed for viewing small, transparent samples at high magnification. A stereoscope microscope, which allows light to shine onto the specimen, is more appropriate for such observations.
Explanation:To see a whole insect under a microscope, you would probably not use a Compound light microscope. The correct tool for observing entire insects is a stereoscope microscope, also known as a dissecting microscope, which uses incident light to shine onto the specimen. This is because compound light microscopes are designed for viewing small samples at high magnifications with light passing through the specimen, which is not ideal for whole insects. Moreover, scanning electron microscopes provide detailed images of the surface of specimens but are not suitable for observing entire, live insects. Simple microscopes, offering a single lens for magnification, also do not suit the demands of viewing a whole insect in detail.
Friction is the force that one surface exerts on another when they rub together. Friction works in the direction opposite to the motion, causing the object to slow down. What is one way you could reduce the friction between two surfaces?
A.) Carpet the surfaces
B.) Put oil on the surfaces
C.) Put sand on the surfaces
D.) Allow one of the surfaces to rust
Answer is B
It is because I did this and got it right and also oil is a liquid so it will immediately stop whatever is coming.
Putting oil on the surfaces can reduce the friction between two surfaces.
Therefore, option B is correct.
What is friction?The resistance to motion created when two objects rub against one another is called friction. Friction occurs whenever two items come into contact with one another. Friction acts in the opposite direction from the motion and works against it. The two surfaces' respective materials have an impact on how much friction exists.
The force that prevents one solid item from moving across another is known as friction. Static friction, sliding friction, rolling friction, and fluid friction are the four main categories of friction. It is a contact force that acts between two surfaces.
Friction can be reduced by putting oil on the surface. Therefore, option B is correct.

You want to cultivate some exotic plants at your farm. However, the climate is chillier than the temperature range favorable to the crop. Which is the best method to use for the cultivation of this exotic crop?
A. use a crop rotation method B. use a lot of fertilizer C. prepare the seed bed properly D. use a greenhouse E. use irrigation
The correct answer is - D. use a greenhouse.
If the climate is not suitable for a certain exotic plant, and the reason for that is that it is colder than the place from where the plant originates, than the best solution is to plant it in a greenhouse.
The greenhouse will provide higher temperature for the plant throughout the whole year, so it is will have a proper temperature, similar to the one it is adapted to. Also, it will receive sufficient amounts of light. It will be protected from the outside influences such as the cold winds, snow, low temperatures, so it will have a good chance of growing.
The introduction of zebra mussels in the Great Lakes is an example of which type of release? The introduction of zebra mussels in the Great Lakes is an example of release.
The introduction of zebra mussels in the Great Lakes is an example of accidental release from ballast water in a foreign container ship.
Answer:
The introduction of zebra mussels in the Great Lakes is an example of an unintentional or accidental release.
Explanation:
The zebra mussel known biologically as Dreissera Polymorph's, is a small freshwater mussel which its species was originally from the lakes in Southern Russia and Ukraine. Known globally as invasive species, they got their name through the striped pattern which are mostly seen on their shells.
Zebra mussels were noticed in Canada in the Great Lakes in 1988 at lake St. Clair. They were believed to be unintentionally released into the lakes in the ballast water of ships going to oceans, traveling the St. Lawrence Seaway. Another belief was linked to the introduction or release through anchors and chains even though this belief has been described as mere speculation.

Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple maggots fed from and laid their eggs in hawthorn trees. After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees. Adult apple maggots will only mate on the type of tree on which they were born.
What is the most likely consequence of the introduction of apple trees to apple maggots?
A. Some apple maggots will undergo adaptive radiation to colonize many other types of trees besides the apple and hawthorn .
B. Populations of apple maggots that mate on different trees could become reproductively isolated and eventually speciate.
C. Apple maggots that are born on apple trees will be unable to reproduce and will eventually die out.
D. Individual apple maggots will eventually learn to lay eggs on both hawthorn trees and apple trees.
your answer is b hope this helps
The correct answer is option B
The population of maggots on the apple tree (apple maggot) that will mate on different trees could become reproductively isolated due to different habitat (ecological isolation).
Ecological isolation causes speciation by creating reproductive barriers between populations due to different habitats.The maggot populations will mate on different trees and will eventually speciate over a period of time.
the kidney is an organ that collects wastes and excess water from the blood and sends them to the bladder where they are stored before being removed from the body. which two systems work together to perform this function?
1) immune and respiratory
2) circulatory and excretory
3) skeletal and nervous
4) digestive and circulatory
The two systems that work together to filter blood, remove waste and excess water, and maintain electrolyte balance are the circulatory system and the excretory system. The circulatory system transports blood to the kidneys, where it is filtered, and wastes are excreted as urine by the excretory system.
Explanation:You're correct to identify the kidneys as playing a critical role in waste removal and water regulation. The role of the kidneys is to filter blood, produce urine, and assist in maintaining water and electrolyte balance. The two systems that work together to perform these functions, based on your provided options, are the circulatory system and the excretory system.
The circulatory system is responsible for transporting blood containing metabolic wastes from cells to the kidneys. In the kidneys, more than a million tiny units called nephrons filter this blood. This filtration involves the removal of wastes and the formation of urine. The reabsorption of water, required ions, and useful compounds back into the capillaries that surround the tubules leaves the wastes behind, and this urine is subsequently collected in the bladder. So, the circulatory system and the kidneys (part of the excretory system) work collectively to filter blood, expel wastes, and maintain water and electrolyte balance.
The excretory system includes the kidneys, ureters, urinary bladder, and urethra, and it's responsible for the removal of waste from the body. The kidneys, as part of this system, ensure that undesirable substances and excess water are excreted from the body in the form of urine, which is stored in the bladder before being eliminated from the body through the urethra.

The circulatory and excretory systems collaborate to help the body expel wastes and maintain water-salt balance. The circulatory system carries nutrient-rich blood to the kidneys, the blood is filtered, and essential substances are reabsorbed back into the bloodstream. The excretory system, specifically the kidneys, separates waste and concentrates it into urine for eventual excretion from the body.
Explanation:The two systems that work together to perform the function of collecting wastes and excess water from the blood and sending them to the bladder are the circulatory and excretory systems. The excretory system, particularly the kidneys, ureters, urinary bladder, and urethra, serve to remove metabolic wastes from the body and maintain water-salt balance through processes of filtration, reabsorption, and secretion carried out by the nephrons.
The circulatory system, on the other hand, delivers nutrient-rich blood to the kidneys, where waste products, excess water, and ions are filtered out and sent into the tubule system of the nephron. Healthy substances are reabsorbed back into the bloodstream, whereas body wastes are separated and concentrated into urine, which is then collected in the bladder for eventual excretion from the body through the urethra.
