The flow of surface run-off can be controlled by building retaining walls called _____.

Answers

Answer 1
Final answer:

The flow of surface run-off can be controlled by building retaining walls called levees, which are key components of flood control systems. In addition to levees, reservoirs collect and store water for various uses, and conservation efforts are important for sustainable water management. Aqueducts and desalination are other methods used to meet freshwater demands.

Explanation:

The flow of surface run-off can be controlled by building retaining walls called levees. The purpose of a levee is to prevent the overflow of rivers, lakes, or oceans from flooding adjacent land. Levees are often part of a larger flood control system, which may include dams and reservoirs. By building a levee, water is contained within the riverbanks, and the risk of flooding to surrounding areas is reduced.

Another method of controlling water flow is through the use of sandbags, which can be placed around potential breaches or leaks in levees or embankments as a temporary measure. According to Environmental Biology 207, sandbags can balance a massive body of water by creating a barrier that stops further flow. Reservoirs also play an essential role by collecting water and storing it for use during drier periods, providing benefits such as water supply, hydroelectric power, flood control, and recreation.

Conservation and Sustainable Management of Water

Conservation is crucial for sustainable water management, involving measures like high-efficiency appliances and behavioral changes to reduce water consumption. In areas where water is scarce, desalination can provide fresh water by removing salt from seawater, although this process is expensive and energy-intensive. Aqueducts transfer water from regions where it is abundant to those where it is needed, but they can lead to controversial political issues and environmental impacts on the source regions.

The least amount of atp is produced in which stages of cellular respiration

Answers

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.

The least amount of ATP is produced in the Krebs cycle of cellular respiration. This stage produces only two molecules of ATP.

What are the different stages of cellular respiration?

There are three different stages of cellular respiration are there:

Glycolysis: Breakdown of glucose into pyruvate.The Krebs cycle: Pyruvate gets converted into acetyl-CoA which enters TCA.Electron transport chain: The product of the TCA cycle enters into the electron transport chain.

The process of glycolysis produces 4 ATP and 2 NADH. But 2 ATP is spent which leads to the net production of 2 ATP and 2 NADH. The process of the Krebs cycle involves the breakdown of acetyl-CoA into 2 ATP, 8 NADH, and 2 FADH2. While the process of the electron transport chain produced 34 molecules of ATP with the help of the conversion of all energetic carriers.

Therefore, the least amount of ATP is produced in the Krebs cycle of cellular respiration. This stage produces only two molecules of ATP.

Describe how comparing early development can help scientists learn about the relatedness of species. give an example!

Answers

Talking of early development we are referring to the embryonic stage of development. The closer similarity of their embryos shows a relationship between the organisms. For example an adult chimpanzee and an adult human being look so different and on the other hand their embryos look so much alike.

Final answer:

Comparing early development in species helps to understand their relatedness by identifying homologous structures stemming from common ancestry. Embryonic similarities such as gill slits that appear in all vertebrates demonstrate shared evolutionary paths. These comparisons aid in the construction of phylogenetic trees to visualize evolutionary relationships.

Explanation:

Understanding Species Relatedness Through Early Development

Comparing the early development of different species can reveal their evolutionary relationships. Scientists look for homologous structures, which are features that are similar due to shared ancestry. An example of this is the presence of gill slits in the embryos of all vertebrates, including humans, which indicates a common ancestral origin. Moreover, scientists use embryology, the study of an organism's development from embryo to adult, to find these connections. The development patterns can help distinguish between homologies and analogies, the latter being similarities due to convergent evolution rather than common ancestry.

For instance, while bats, birds, and insects all have evolved wings for flight, the embryonic origin and structural makeup of these wings differ significantly. Birds and bats have homologous structures in their wings suggesting a closer evolutionary relationship, whereas insect wings are analogous and do not imply close relatedness. Such comparisons enable researchers to construct phylogenetic trees, illustrating the evolutionary pathways of different species.

3. The energy makes the air particles move faster, they collide with others that are at a lower temperature, that move more slowly. As they collide, fast particles yield some of their energy to slower ones. These in turn collide with other adjacent particles. This process continues until the energy is extended to all the particles of the air that was initially at a lower temperature. Finally they all reach the same kinetic energy and consequently the same temperature.

List three reasons that can help explain why it is important to distinguish different tastes?

Answers

Different vital nutrients have broadly unique tastes. We all require certain amounts of nutrients, such as sugars or salts for example, in our diet. The tastes of these broad characteristics of nutrients are fairly distinct from each other, and this allows us to consume the correct foods when we require a particular nutrient in our diet.

Some substances that can be harmful to us in large amounts have disagreeable tastes, such as acidic foods for example.

Taste is one of our primal senses that may have had a more important role in the past than just tasting food. For example, territorial animals like wolves often 'taste' the scent to other wolves that have been in an area.

How does budding in yeast resemble fission in paramecium? How does it Differ?

Answers

they're both forms of asexual reproduction

Binary fission and budding are both the procedures of asexual reproduction. They are both very identical; however, they do possess certain differences. They are regarded as the most basic methods of asexual reproduction.  

Binary fission takes place majorly in unicellular species. When the species has to reproduce its cell goes via the phases of mitosis. However, when it attains cytokinesis it divides into two distinct organisms.  

Budding is another kind of asexual reproduction. In this process, a new species called bud originates from the original organism. As soon as the bud possess the tendency to survive on its own it distinguishes itself from the original organism.  

It takes place in both the multicellular organisms and unicellular organisms. However, unlike binary fission, it takes place from an unequal division of the reproducing organism.

Answers

D. They are long and narrow depressions at subduction zones

Deep ocean trenches are not associated with mid-ocean ridges. The correct option is A.

What is a Deep ocean trench?

Deep ocean trenches are actually associated with subduction zones, which are areas where one tectonic plate is being forced beneath another plate.

They are typically located at the boundaries of tectonic plates where oceanic crust is being subducted beneath either another oceanic plate or a continental plate.

Mid-ocean ridges, on the other hand, are divergent boundaries where tectonic plates are moving away from each other, resulting in the upwelling of molten material from the mantle and the formation of a new oceanic crust.

These ridges are characterized by volcanic activity and the creation of new seafloor.

Explain what happens in the large intestine to cause diarrhea or constipation. how does the function of the large intestine relate to another key resource?

Answers

Answer: Diarrhea or constipation can be caused when the muscles of the large intestine do not function properly

Explanation: Diarrhea is caused when an infection or illness cause the body to release too much water into the intestines in order to flush them out. Constipation is the opposite; not enough fiber causes a backup of stool in the large intestine. The colon's main job is to absorb water, nutrients and electrolytes from partially digested food, the rest is pushed down as waste (feaces)

Muscles in the colon work to get rid of the body's waste products. They contract and relax as they push the undigested food through the large intestine. If the muscles in the colon don't work at the right speed for proper digestion or if the coordination with muscles in the rectum or pelvis is interrupted, the contents of the colon can't move along smoothly. When this happens, a person can feel the belly cramps, bloating, constipation, and diarrhea  

Diarrhea and constipation are caused by disruptions in the GI tract's normal function in the large intestine, resulting in loose or hardened stools.

Diarrhea occurs when the large intestine discharges its contents before water reabsorption is complete, resulting in loose stools. Conversely, constipation happens when the colon retains contents for too long, leading to hardened feces. Both conditions are caused by disruptions in the GI tract's normal function.

C. Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.
D.The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.

Answers

A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.

Viscosity refers to the thickness of blood. This thickness is caused by the number of red blood cells. Thick blood travels through blood vessels at a slower rate than thin blood.

High blood viscosity increases the resistance in the blood vessels and leads to slower blood flow describes one of these factors and its effect on blood flow. Thus, option B is correct.

What is viscosity?

The thickness of a liquid in known as viscosity or its property of being sticky and its consistency which is created due to the friction present inside it.The unit of viscosity is newton- second per square meter and it is written as pascal-second in SI system.

There are several methods by which viscosity is measured and these are rotational rheometry, non-contact rheology, vibrating viscometers, capillary viscometers.

I'm not a biologist, so I don't know the actual answer. But my best guess is that there is more in fruits and vegetables than just simple sugars or even complex carbohydrates. There are vitamins for example. Some of the vegetables have simple proteins which are much easier to break down that the complex ones found in meat. 

Explanation:

Complex carbohydrates like fruits, vegetables, whole grains, beans, peas etc. They contain vitamins, minerals and fibres, that's why they are the source of long lasting energy because they take long time to digest.

Complex carbohydrates are healthier than simple carbohydrates like sugar are present in fruits, table sugar, soft drinks, milk and milk products etc. They digested quickly not the long lasting as complex carbohydrates, they can easily broken down by the body.

Complex are better dietary choice because it contains more nutrients than simple carbs. They are high in fibre and digested slowly, this is the better way for weight control.

Distinguish between the structure of pyrimidines and purines. explain why adenine bonds only to thymine.

Answers

Pyrimidines have a single ring structure. Purines have a double ring structure. Adenine and thymine bind together as they’re complementary base pairs to one another, and form 2 hydrogen bonds upon binding

Final answer:

Pyrimidines, such as cytosine and thymine, are single-ringed structures, while purines, like adenine and guanine, are double-ringed. Adenine bonds only to thymine because they can share two hydrogen bonds, maintaining DNA's stable helix structure.

Explanation:

Distinguishing Between Pyrimidines and Purines

The structure of DNA nucleotides includes two distinct types of nitrogenous bases known as pyrimidines and purines. Pyrimidines are single-ringed structures and include cytosine (C) and thymine (T). In contrast, purines are double-ringed structures represented by adenine (A) and guanine (G).

When it comes to the bonding of these bases, adenine forms bonds only with thymine due to the ability of these to share two hydrogen bonds. This selectivity in bonding is also facilitated by the way DNA structures its nucleotide pairings—one purine with one pyrimidine—providing the necessary spacing to maintain the helix's integrity. The double-ring of a purine and the single-ring of a pyrimidine together form a pairing of a consistent shape and size, critical for the DNA structure. For this reason, adenine cannot pair with another purine such as guanine because it would create too much spatial hindrance, nor can it pair with another pyrimidine like cytosine due to excessive spacing.

So, adenine bonds only to thymine due to their matching ability to create two hydrogen bonds and the structural conformity that results when a purine is paired with a pyrimidine, thereby maintaining the optimal width of the DNA helix.
