How does the movement of water, carbon, and nitrogen in ecosystems differ from the movement of energy?
Please help me this is due today, thank you if you do^^
Answer:
While water, carbon, and nitrogen cycle through the ecosystem, energy flows through an ecosystem.
Explanation:
There is a limited amount of water, carbon, and nitrogen in an ecosystem, and therefore, it cycles and passes through an ecosystem multiple times. In the case of energy, however, it is different. Energy goes into a system, flows from organism to organism, and then leaves the system. For example, with water, that water will rain, gather in a river or body of water, and evaporate, doing the cycle over and over again. Energy from the sun however, gets collected by producers, then flows to the organism that eats the plant, then flows to the organism that eats that organism, and so on. The energy does not return to the sun, it just leaves the system (like for example when an organism dies).
How do you get 0 blood type?
Answer:
You cannot change your blood type. You are born with what you are biologically given and it is permanent.
Answer:
What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child. Each of their kids has around a 1 in 8 chance of having O negative blood. This is possible because both O and Rh- are something called recessive traits.

Aliyah found a tarnished silver dollar and recalled that tarnish results when metals react with oxygen or sulfur compounds in the air. She polished the silver dollar to remove the tarnish until it was shiny again. She also polished a copper bracelet and a gold ring. What physical property of these metals makes them shiny?
Answer:
LUSTER
Explanation:
The physical property of the metals that make them shiny is called Luster. Therefore, Aliyah was able to polish the metals like silver, copper, and gold.
What is luster?Luster is one of the important physical properties of the metals, which refers to the way light is reflected from the surface of the metal. In the context of metal, luster refers to the shininess or brightness of the metal surface.
The luster of a metal ranges from dull to very shiny and can influence the perceived value of the metal as well as its suitability for various applications.
The luster of a metal can be affected by factors such as surface roughness, impurities, and exposure to environmental conditions such as corrosion and oxidation.
The treatment of a metal surface, such as polishing and plating, can also impact the luster of a metal.

If a cell does not go through the Sphase of the cell cycle before mitosis, what might be wrong with the daughter cells?
Answer:
Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.
Explanation:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.
-----------------------------------------------
As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.
Many regulator molecules act during the different stages of the mitosis process to make it possible.
There are too many factors interacting, activating, and deactivating to pass from one stage to another.
Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.
When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.
Once that stage is over, that cyclin concentration decreases, and the following one increases.
But if any step was not correctly performed, the cell can not pass to the following one.
During the S stage of the interphase occurs the DNI replication process.
At this point, also occurs the synthesis of histones and other associated proteins.
This is the only stage where the DNI molecule is replicated.
S phase cyclins are in charge of regulating the stage of DNA replication.
If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.
The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
