Answer:
c
Explanation: this is the correct answer
Answer:
Correct answer: c) it prevents minerals in the water from flowing into the cell
Giant tube worms are marine invertebrates , it can survive in a complete darkness at depth of 5.280 feet. They inhibit the areas near the hydrothermalvent that release extremely hot water filled with minerals, which help them to maintain a constant environment inside the cell.
Giant tube worm live in a symbiotic relationship with microorganism . Bacteria prepare food in return to accommodation. It do not have eye, leg and stomach.
how do skin cells replace itself after an injury?
a) skin cells go through the process of budding to make new identical cells.
b) skin cells go through the procces of mitosis to make new identical cells.
c) skin cells go through the process og photosynthesis to make new identical cells.
d) skin cells go through the process of cellular respiration to make new identical cells.
Answer:
d
Explanation:
as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration
Answer:
b) skin cells go through the process of mitosis to make new identical cells.
Explanation:
The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.
This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.

Nutrition is a broad field that involves the foods you consume, the nutrient content of those foods, and how those foods and their nutrients affect your health and wellness. Health effects can include how you feel on a daily basis, as well as your risk for certain diseases in the future.
Choose the option below that does not describe the science of nutrition.
A. Many studies have been conducted on the association between certain types of cancer and diet and, therefore, these links are well-understood.
B. Matters surrounding global food supply and food production are integral parts of the study of nutrition.
C. Nutrition science involves the study of the digestion and absorption of food.
D. Recent focus in nutrition science has shifted to the prevention of conditions like heart disease and diabetes
Answer:
A
Explanation:
The correct option that does not describe the science of nutrition would be that many studies have been conducted on the association between certain types of cancer and diet and, therefore, these links are well-understood.
While truly indeed many studies have been conducted linking certain types of cancer and diet, scientists are far from understanding the link between diets and cancer. While some degrees of understanding exists, it is not 100% certain that there is a cause-effect relationship between these two factors, and a large percentage of cases of cancer are caused by factors that cannot be controlled.
The correct option is, therefore, A.

2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.
Answer:
C. Both are primary producers.(THIS IS THE CORRECT ANSWER)
Explanation:
Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.
It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements. Kelps forests are shelters for these bacteria and hence both are found near the source of energy.Hence the option B both are primary producers.

Answer: I'm pretty sure this is true
Explanation:
The Earth remained a frozen snow ball until carbon dioxide levels in the atmosphere increased. Why did carbon dioxide from the volcanoes fill the atmosphere?
Answer:
Because the land surface was then largely covered in ice, continental weathering effectively ceased. This locked the planet into a 'Snowball Earth' state until carbon dioxide released from ongoing volcanic activity warmed the atmosphere sufficiently to rapidly melt the ice cover. This model does not, however, explain one of the most puzzling features of this rapid deglaciation; namely the global formation of hundreds of metres thick deposits known as 'cap carbonates', in warm waters after Snowball Earth events.
The Southampton-led research, published in Nature Geoscience, now offers an explanation for these major changes in ocean chemistry.
Lead author of the study Dr Tom Gernon, Lecturer in Earth Science at the University of Southampton, said: "When volcanic material is deposited in the oceans it undergoes very rapid and profound chemical alteration that impacts the biogeochemistry of the oceans. We find that many geological and geochemical phenomena associated with Snowball Earth are consistent with extensive submarine volcanism along shallo
Explanation:
Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
diameter of 10 cm in the box. Susan puts 1,000 1-cm glass marbles in her box.
1. Whose box has more empty space? Explain.
Answer:
Both boxes have the same amount of empty space
Explanation:
Given
Cube Box
[tex]Length = 10cm[/tex]
Robert:
1 glass marble
[tex]Diameter = 10cm[/tex]
Susan:
1000 glass marble
[tex]Diameter = 1cm[/tex]
Required
Whose box has more empty space?
First, we need to calculate the volume of the cubic box.
[tex]Volume = Length^3[/tex]
Substitute 10cm for Length
[tex]Volume = 10^3[/tex]
[tex]Volume = 1000cm^3[/tex]
Next, calculate the volume of Robert's glass
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 10cm[/tex] --- Given
Substitute 10 for diameter
[tex]r = \frac{1}{2} * 10cm[/tex]
[tex]r = 5cm[/tex]
So:
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 125[/tex]
[tex]Volume = 523.8cm^3[/tex]
Next, we determine the volume of Susan's 1000 glasses
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 1cm[/tex] --- Given
Substitute 1cm for diameter
[tex]r = \frac{1}{2} * 1cm[/tex]
[tex]r = 0.5cm[/tex]
Substitute 0.5cm for radius in [tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.125[/tex]
[tex]Volume = 0.5238[/tex]
But there are 1000 glasses.
So, the volume of 1000 glasses is:
[tex]Volume = 0.5238 * 1000[/tex]
[tex]Volume = 523.8cm^3[/tex]
--------------------------------------------------------------------------------------------------------------
For Robert:
[tex]Volume = 523.8cm^3[/tex]
For Susan:
[tex]Volume = 523.8cm^3[/tex]
Since, they have the same volume.
Both boxes have the same amount of empty space
From the dimensions of glass marble for robert and susan, we can say that; none of the given boxes have more empty space.
We are told that the cubic boxes have a measure of 10 cm for its' sides.
Formula for volume of a cube is;
V = lwh
where;
l is length
w is width
h is height
Thus; V = 10 × 10 × 10
V = 1000 cm³
For Robert;
We are told that he puts a glass marble with a diameter of 10 cm in the box. The glass is usually spherical in shape and the volume of a sphere is;
V = ⁴/₃πr³
Thus;
V_rob = ⁴/₃π × (10/2)³
V_rob = 523.6 cm³
Volume left for rob = 1000 - 523.6
Volume of empty space left for rob = 476.4 cm³
For Susan;
V = ⁴/₃πr³
Thus;
V_sus = ⁴/₃π × (1/2)³ × 1000
V_sus = 523.6 cm³
Volume left for susan = 1000 - 523.6
Volume of empty space left for susan = 476.4 cm³

Explanation:
Clostridium Difficile (C. difficile) is a type of bacteria that increases its activity with most antibiotic use, and is therefore very difficult to treat. Research shows that the most effective way to prevent the spread of infection is frequent handwashing. However, many people have flat-out refused to wash their hands in hospitals. The government is contemplating passing a policy to make it mandatory for people entering hospitals to wash their hands or else risk not being seen by doctors and being escorted out of the building against their will. Do you think the government should go ahead with this plan?
Consider and discuss the legal, ethical or practical problems that exist for each action option and conclude with a persuasive argument supporting your decision.
Answer:
The government should not go ahead with this plan.
Explanation:
If the government decides to proceed with its plan to pass a law that authorizes the management of a hospital to force people who refuse to wash their hands out of a hospital and deny them medical care against their will, then the government will be infringing on people's right to life. While it is necessary to prevent the spread of Clostridium Difficile (C. difficile) , any law that is made to that effect must not abuse the right of access to medical care which is a fundamental right of citizens. This action will be ethically incorrect because it amounts to a government using a high handed approach in discharging its duties.
However, the intention of such a law is to protect the citizenry from the bacteria Clostridium Difficile (C. difficile) . If such a law is not passed, more people may become infected by the bacteria owing to the carelessness of other people. This situation is made worse because the organism is resistant to antibiotics.
However, since prevention of the spread of Clostridium Difficile (C. difficile) is Paramount, I opine that the government should continue to enlighten citizens and appeal to them on the need to practice regular hand washing in order to protect themselves and other people. Passing the said law is a draconian approach to the problem hence it is not in line with the ethics of modern civilization.
It is more civil to continue to appeal to citizens and sensitize them on the importance of regular hand washing as it affects the spread of Clostridium Difficile (C. difficile) .

how do the weight of objects on earth compare the weight of the objects on the moon why do you think this is
Answer:
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quantity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
hope this helps you out love!! <3
Answer:
weight of objects on EARTH> weight of objects on MOON
Explanation:
weight= mass * gravity
assuming both objects have the same mass, the environment with greater gravity will result in a greater weight
gravity of earth > gravity on the moon
so
weight of objects on EARTH> weight of objects on MOON

What is unique about the
protein channels which allow molecules to travel by facilitated diffusion?
A. Each channel only allows one type of molecule to pass through it
B. The channel modify the molecules DNA as they pass-through
C. The channels move molecules very quickly
Please help!!!! 10 points
Answer:
A. Each channel only allows one type of molecule to pass through it
Explanation:
Transmembrane proteins from channels spanning the membrane that create hydrophilic tunnels. They only enable diffusion across the protein channel into the cell, for their target molecules.
These are highly specific-they only allow one type or group of related molecules to use the channel. These are types of transmembrane channels, embedded within the membrane, help to maintain selective permeability, while simple diffusion of other small, uncharged molecules can readily occur.
