two divers are swimming in clear ocean water at a depth of 150 m. The first diver is wearing a white wet suit. When the second diver sees the first diver at that depth, which of the following colors would he see?

Answers

Answer 1
The second divers is going to see COLOR BLUE.
Water has the ability to transform light, thus colors appear differently in water.  Generally, water absorbs warm colors and scatter the cooler colors. In clear ocean water, visible light decreases approximately 10 folds for every 75 meters that one descend. Thus, at the depth of 150 M, the white suit will appear to be blue in colour.
Answer 2
Note the question is missing the multiple choice answers to choose from, however, we can still provide a meaningful answer.

Light from the sun is a composite of a full spectrum of light, ranging from very long wavelengths (such as radio waves) all the way to very short wavelengths (such as xrays and gamma rays). Visible light - the light we can see - occupies a tiny slither of the electromagnetic (light) spectrum and ranges from blue/violet (around 400nm wavelength) up to red (around 700nm wavelength).

Now back to the question. Water is much more dense than space or air, and as a result, water causes light to attenuate when it passes through it. This means parts of the light are absorbed as they travel through the water medium. Generally, higher energy light has more penetrative power and the energy contained in light is proportional to it's wavelength; the shorter the wavelength the higher the energy. This means blue light (400nm) is higher in energy than red light (700nm). So, as light passes though water, the lower energy wavelengths are attenuated (absorbed) first. This means red disappears first, then followed by orange, yellow, green, and finally blue and ultraviolet. At 150m depth, depending on how clear the water is, only blue light would remain and it would be quite dark.

Ecological succession that occurs in an area where no ecosystem existed before (such as bare rock with no soil) is called:
a. primary succession
b. secondary succession
c. ecological succession
d. keystone succession

Answers

Final answer:

Primary succession is the type of ecological succession that occurs in an area where no ecosystem existed before, such as bare rock with no soil.

Explanation:

The correct answer is a. primary succession. Primary succession is the type of ecological succession that occurs in an area where no ecosystem existed before, such as bare rock with no soil. This process begins with pioneer species, such as lichens and mosses, that can tolerate harsh conditions and gradually break down the rock to form soil. Over time, more complex plant and animal species colonize the area and create a stable ecosystem.

Explain how some people applied darwin's theory of natural selection to modern human societies

Answers

Darwin's theory was that strong species would survive and the weak ones would die. while in society the strong people and bussinesses would prosper, and the weak ones would fail.
Final answer:

Social Darwinism was a misinterpretation of Darwin's theory that some people applied to modern human societies to justify social class distinctions and racism. However, this interpretation was discredited and does not align with Darwin's original scientific discoveries.

Explanation:

Social Darwinism, a misinterpretation of Darwin's theory, was applied to modern human societies by some individuals in the 19th and 20th centuries. It suggested that societal success and power were determined by superior breeding and those who were deemed weaker should perish. This theory was used to justify social class distinctions and racism. However, it is important to note that this interpretation of Darwin's theory was discredited and does not align with his original scientific discoveries.

Once the body has begun shivering, what happens to make it stop shivering?

A) When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shivering.

B) When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shivering.

C) When body temperature is below normal, the nervous system sends a message to the skeletal system to stop shivering.

D) When body temperature is below normal, the respiratory system sends a message to the muscular system to stop shivering.

Answers

I believe the answer is D. Hope this helps ;D

Answer: Option B

Explanation:

When the body is exposed to the colder temperature then it starts shivering and this response is the part of homeostasis. During this process the nervous system sends signal to muscular system which stimulates shivering to make the body temperature normal.

When the body temperature comes to normal again the nervous system sends a signal to muscular system to stop the shivering.

Thus, the correct answer is "Option B".

Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 our life uses. what would be the minimum length of a codon which could represent all 20 currently used amino acids?

Answers

The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.

Adults often provide indirect feedback about grammar by using __________, which restructures inaccurate speech into correct form.
a.fast-mapping
b.an expansion
c.overregularization
d.a recast

Answers

Recasting (d) is the correct answer. By doing this, the errors are corrected, yet the flow and general communication is not obstructed. The adult (or other person) will simply restate the proper grammatical form to the learner before continuing the conversation.

Final answer:

Adults often use a recast to provide indirect feedback on grammar, subtly correcting a child's speech by incorporating the correct form in their response. This method allows children to learn the proper usage through exposure in a natural conversational context. It contrasts with overregularization, where children apply grammatical rules too broadly, demonstrating the refining role of recasts in language acquisition. The correct option is d.

Explanation:

Adults often provide indirect feedback about grammar by using a recast, which restructures inaccurate speech into correct form. This method involves adults responding to a child's incorrect utterance by subtly correcting the mistake within their reply, without explicitly pointing out the error or demanding correction from the child. For instance, if a child says, "I goed to the park," an adult might respond, "Oh, you went to the park? That sounds fun!" Here, the adult is not directly correcting the child but providing the correct form of the verb. This technique is beneficial because it models the correct usage in a natural context, helping the child to internalize the correct form through exposure rather than through direct correction.

Recasts contrast with approaches like overregularization, where children apply general grammatical rules too broadly, leading to errors. While overregularization reflects a child's growing understanding of language rules, recasting helps to refine this understanding by providing correct models in response to mistakes. For example, overregularization might lead a child to say "foots" instead of "feet," and an adult might use a recast by saying, "Yes, your feet look cold."

Answers

The cruciate ligament is the one that limits the anterior and posterior movement of the femur and maintain the alignment for the femoral and tibial condyles. This ligament is a band of tissue that connects the bones within the knee.
Final answer:

The anterior and posterior cruciate ligaments limit the anterior-posterior movement of the tibia and align the femoral and tibial condyles for knee stability.

Explanation:

The ligaments that limit the anterior-posterior movement of the tibia and maintain the alignment of the femoral and tibial condyles are the anterior cruciate ligament and the posterior cruciate ligament. These intracapsular ligaments are essential for knee stability. The anterior cruciate ligament prevents hyperextension, while the posterior cruciate ligament prevents anterior sliding of the femur over the tibia when the knee is flexed and weight-bearing, such as when walking downhill.

during diffusion, how do the molecules physically get from one place to the other? (spaceship tractor beam, winged monkeys)

Answers

Molecules move from high concentration to low concentration depending on passive or active transport. Active transport is when the nutrients are actively moving out of the cell and passive is when the nutrients or ‘molecules’ are going into the cell this is because cells have a semi permeable surface. Only letting in specific molecules.

During diffusion, molecules move from the region of higher concentration to the region of lower concentration.

For diffusion to occur, there must exist a diffusion gradient which is the difference in the concentration of the substance in the two regions.

Therefore, the diffusion gradient is the driving force that allows diffusion to take place.

Some characteristics of diffusion include:

Diffusion is rapid when the concentration gradient is large.It slows down when the difference in the concentrations become less.When the molecules (solute) are evenly distributed in the medium (solvent), we say a dynamic equilibrium has been reached.

Sofia was 6 pounds at birth. she is a healthy baby. She should be 18 pounds when she is 1 year old. The correct option is C.

What is a healthy weight for a baby?

Typically, a baby should weigh between 2.5kg and 4.5kg at birth, with 3.5kg being the average.

Your baby's birth weight is the measurement made immediately after birth. A baby with a low birth weight is one that weighs less than 5 pounds, 8 ounces.

Boys typically weigh more at birth than girls do, and this pattern persists as kids become older, with girls weighing approximately a half pound less. But as toddlerhood approaches, girls catch up quickly. By 19 months of age, the majority of them are half their adult height.

Up until the sixth month, a baby would gain somewhere between 140 and 200 grammes per week.

Thus, the correct option is C as per the above details.

Which property of water explains its ability to prevent sudden changes in body temperature?

Answers

(High) Heat Capacity

Heat capacity is the amount of heat needed to raise the temperature of a substance by 1 unit degree (Celsius, Kelvin, Fahrenheit, Rankine). 

Water has a relatively high heat capacity, which means that it would have to absorb relatively large amounts of heat before it could actually have a large change (i.e. increases) in temperature. Conversely, it would have to give off a lot of heat in order for it to cool down.

The heat capacity of 1 gram of water is 4.184 Joules/°C, which means that 1 gram of water needs 4.184 Joules of heat to increase its temperature by 1°C. In comparison, 1 gram of copper only needs 0.385 Joules to raise its temperature by 1°C, which means that copper heats up by about 10 times more than water when subjected to the same amount of heat.

SCIENCE!!! HHHEEELLLPPP!!!
Are viruses alive? This a question debated among scientists throughout the world.

Scientists discovered the tiny, disease-causing agents that were believed responsible for such diseases as rabies and hoof-and-mouth disease. Initially, scientists classified viruses as “living”, but in 1935, they began to change their thinking.

Scientists crystalized the tobacco mosaic virus, noting that it did not have cell structure, of even the simplest kind. There was no membrane, no nucleus, and no ribosomes. They determined that a virus was nothing more than a strand of nucleic acid, DNA or RNA, protected by a protein shell. Scientists also believed that viruses lacked the mechanisms necessary for metabolic function.

Some scientists argued that viruses are capable of response to stimuli. When not in a favorable environment within a host cell, the virus remains an unchanging, dormant, organic particle. But once in contact with the susceptible host or in a favorable environment, the virus becomes active, injecting its nucleic acid into the host cell, and eventually self-replicating. In this manner, one virus is capable of producing many other viruses, identical to the original, to attack host cells.
