DONE
Answer:
to perform specific functions for the body
so organisms can have a variety of cells in
case they need them
Explanation:
Organisms do not decide which cells are needed each day; all cells are inherently needed (at least in the vast majority of cases). To perform specific functions for the body so organism can have a variety of cells in case they need them is the correct answer; we can't have cells all performing the same task; we have a variety of needs.

Orcas are endangered whales. Only about 80 individuals remain off the 1 point
coast of Washington State. Salmon are a source of food for orcas. Some
individuals are proposing that four dams in Washington State be removed
so that habitat areas for salmon will be increased. Those opposed to the
dam removals say that the dams provide low-cost hydroelectric power and
positively influence the local economy. This situation is an example of:
The issue at hand is an environmental conflict of interest between conserving endangered species (orcas and salmon) and economic developments (hydroelectric power from dams and their beneficial influence on the local economy).
Explanation:This situation is an example of an environmental issue that involves a conflict of interests between environmental conservation and economic considerations. On one hand, the removal of dams would be beneficial for the survival of both the salmon and the orcas which are endangered species. This is an argument grounded in the principle of biodiversity conservation. On the other hand, the dams contribute to the economy by providing low-cost hydroelectric power which supports the local economy. This represents the perspective of economic development and utility. In both cases, the decision would have significant impacts on the environment and the economy.

Which of the following best explains why overfishing is considered a bad practice
Final answer:
Overfishing is bad because it causes overharvesting of aquatic species, leading to fishery collapses like the western Atlantic cod fishery and potential species extinction. It is exacerbated by the tragedy of the commons and advanced fishing technology, with severe ecological and socioeconomic consequences.
Explanation:
Overfishing is considered a bad practice because it leads to overharvesting which poses a serious threat to many species, particularly aquatic species. A well-known example of such overharvesting leading to fishery collapse is the western Atlantic cod fishery. Overfishing, driven by economic and political factors, is often exacerbated by the tragedy of the commons, where no individual fisher has an incentive to exercise restraint when harvesting from a shared resource. As a result, fisheries managed as common resources tend to be overexploited, despite regulatory efforts, which could lead to unsustainable exploitation and potential fishery extinction. Advanced fishing technology further increases the risk of overfishing, allowing fishers to harvest at a scale that far outpaces the biological growth rates of the species. In some extreme cases, this may result in the economic drive to fish a population to extinction, as seen in the case of certain whale species. The consequences of overfishing are not only ecological but also socioeconomic, dramatically affecting the lives of those who rely on the fishery for their livelihood and causing a shift to smaller, less profitable species in fisheries.
Descibe how changes to genes can affect the traits of organisms.
Please elaborate, as this is supposed to be a "discussion"
PLS ANSWER DUE TOMMORROW
double the points
thank you
Answer:
Please find the explanation below.
Explanation:
Changes in the genetic sequence of a DNA is called MUTATION. A gene is a segment of the DNA that holds information for the synthesis of proteins, which are responsible for the observable traits in organisms. The expression of a gene brings about the synthesis of a protein that effects a particular trait in an organism. The gene is expressed in two major stages viz: transcription and translation.
Transcription involves production of an mRNA molecule using the encoded information in the genes of a DNA while translation is the synthesis of a protein using the mRNA as a template.
Since, the order of the sequence in a gene determines the order of the sequence in the mRNA which ultimately determines the order of sequence in the protein, a change in the gene of an organism will affect the observed trait of that organism.
More detailedly, a change in the gene will cause a change in the mRNA sequence during transcription. A change in the mRNA sequence will cause a change in the amino acid sequence during translation. A change in the amino acid sequence will affect the protein produced i.e. might not be functional or may not be produced at all. An affected protein will cause a trait in that organism to be affected.

It is a lovely summer's day in John's greenhouse. Various factors affect the rate of photosynthesis: • light intensity • temperature • carbon dioxide concentration Which one of the factors above is likely to limit the rate of photosynthesis of John's tomato plants? Explain your answer
Answer:
Light intensity
Explanation:
John’s greenhouse for sure wasn’t open. It would have consisted of a closed system. The most important aspect of photosynthesis is the reaction between the light and the chlorophyll( green pigment) of the plant.
The closed system is more likely to permit a reduced amount of light intensity which is more likely to affect the tomato plant’s photosynthetic process.
Answer: light intensity,temperature and Carbondioxide concentration can together affects the tomato plants growth
Explanation:
Photosynthesis is the process whereby green plants produce there own food. It is affected by a number of factors;
Light intensity- Light energy from sunlight is what is trapped by plant and used in the production of ATP( adenosine triphosphate) and NADP which are energy that is available for photosynthesis. when light intensity is low it will affect the rate of photosynthesis in tomato plants
2. Cabondioxide concentration- Co2 is a reactant in photosynthesis and a low concentration will reduce the rate of photosynthesis in the tomato plants
3. Temperature- plants stomach closes and open in response to temperature changes. At very high temperature stomata is always closes to conserve water and this reduces the in flow of carbondioxide hence its also an important factor in the growth of the tomato plants.

Which organisms are most likely to survive in a population in which disruptive selection is occurring? organisms that have average traits, organisms that have extreme traits, organisms that have the greatest number of offspring, or organisms that are the largest and strongest
Answer:
The correct answer is organisms that have extreme traits.
Explanation:
Disruptive selection is a specific type of natural selection that describes changes in population genetics. In disruptive selection, both extreme values for a trait are favored over intermediate values. As a result, the population is divided into two distinct groups and the variance of the trait increases.
The organisms that have extreme traits are most likely to survive in a population in which disruptive selection is occurring.
Disruptive selection:
The population genetics change is favored by the extreme trait values over the average. This selection divides a population into two groups results in an increase in population.
For Example- If a rabbit population consists of pure black and white-fur traits was put into an area that had very dark black rocks as well as very white-colored stone.
The rabbits with black-furred will be able to hide in the black rocks.The white-furred rabbits will hide in the white rocks, But the gray-furred rabbits would stand out in both of the habitats, and hence they will not survive.Therefore, the organisms that have extreme traits, are most likely to survive in a population in which disruptive selection is occurring.

Answer:
It is important to highlight the wording of your question is not very good.
Although it could help you saying that chyme is a set of foods and certain treated by the gastrointestinal tract.
The pancreatic juice is the exocrine secretion of the pancreas, produced by the pancreatic acini and is released through the main pancreatic duct along with the coldodoco in the second portion of the duodenum through the Vater ampoule.
The intestine once the chyme reaches it (in simple words the serious chyme the ex food bolus) intestinal juices are released that continue with the degradation of food, in this part of the intestine, mainly in the duodenum is where more nutrients are absorb, that is why it is where most nutritional importance is usually assigned to this area of the digestive tract.
Explanation:
In the intestinal absorption, the quality of the intestinal mucosa plays a very important role, which is why those people who suffer from celiac disease or chronic chronic disease will be affected by the absorption of certain nutrients, triggering possible hypovitaminosis or anemias.
Pancreatic juices and intestinal juices already play an important role in the assimilation of amino acids or more complex molecules than carbohydrates

Answer:
I'm guessing you want the definitions for each of the phases right?
Explanation:
Prophase: Chromatin in the cells nucleus condenses and chromosomes start pairing up
Metaphase: Chromosomes line up at the center of the cell.
Anaphase: The sister chromatids separate and split off from each other to the opposite sides of the cells.
Telophase and Cytokinesis: Membrane starts forming around each set of chromosomes on two opposite sides of the cells. Cell divides into two identical daughter cells.
The four phases of mitosis are -

Explain how burning fossil fuels can lead to a lower ocean pH
Answer:
the process of the ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulating in the atmosphere, where it causes global warming but it also affects our oceans. As carbon dioxide enters the ocean, it reacts with the sea water to form carbonic acid
Explanation:
I just know
Carbon dioxide emitted by the combustion of fossil fuels piles up in the atmosphere, where it contributes to global warming. However, it also has an impact on our oceans. Carbonic acid is formed when carbon dioxide enters the ocean and reacts with sea water.
What is ocean acidification?The massive amount of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.
This is known as ocean acidification, and it is causing a sea change that is endangering the ocean's fundamental chemical balance.
Carbon dioxide from the combustion of fossil fuels accumulates in the atmosphere, contributing to global warming.
It does, however, have an impact on our oceans. When carbon dioxide enters the ocean and reacts with sea water, carbonic acid is formed.
Acting on climate change and implementing solutions to drastically reduce the use of fossil fuels is the most effective way to limit ocean acidification.
We can reduce the harm to marine ecosystems if we reduce global warming emissions and limit future warming.
Thus, this way, burning fossil fuels can lead to a lower ocean pH.

The climate of a region can be influenced by many things, such as the altitude and latitude of a region or the presence of a nearby body of water.
A region that is near a large body of water would likely be_____ in the winter and______ in the summer than a region that is not near water.
Answer:
The correct answer is "warmer; colder".
Explanation:
One of the advantages of living in a coastal zone, or in other words a region near a large body of water, is that the winters are warmer and the summers are colder than regions that are not near to water. Water helps land to heats and cools more slowly, therefore it provides are relatively stable temperature all around the year in comparison to lands that do not have large bodies of water nearby.
A region that is near a large body of water would likely be warmer in the winter and cooler in the summer than a region that is not near water.
Proximity to large bodies of water influences regional climates, resulting in milder winters and cooler summers near water. Understanding Oceanic and Continental climates provides insight into temperature variations between coastal and inland areas. The effect of proximity to large water bodies on climate is significant, impacting temperature moderation and regional climate differences.Areas near a large body of water would likely be milder in the winter and cooler in the summer than regions not near water. Large bodies of water have a temperature moderating effect, leading to more moderate climates in coastal areas.Oceanic and Continental climates are distinguished by their proximity to large water bodies, impacting temperature variations between coastal and inland regions.Proximity to a large water body plays a significant role in moderating temperatures and creating differences in climate between regions near water and those farther inland.Which of the following is NOT a reason that scientists classify organisms?
