Explain why inmates who have been in the dark cell for quite long usually have problems with their eyes and usually squint when in bright light?
Answer:
No one can see in total darkness. Fortunately, there’s almost always some light available. Even if it’s only dim starlight, that’s enough for your eyes to detect. What’s truly amazing is how little light is required for you to see.
Human eyes have two main features that help us see better in low light: the pupil’s ability to change size, and the eye’s two types of light-sensing cells.
Opening up to let in more light
Your pupils are the black areas at the front of your eyes that let light enter. They look black because the light that reaches them is absorbed inside the eyeball. It’s then converted by your brain into your perceptions of the world.
You’ve probably noticed that pupils can change size in response to light. Outside on a bright sunny day, your pupils become very small. This lets less light into the eye since there’s plenty available
An Apple is Resting on a table.Claire says that there are no forces acting on the apple because it is not moving.is she right?
Answer:
Claire is wrong.
Explanation:
Claire is wrong because gravity always acts upon a resting object.
An apple is resting on a table. Claire says that there are no forces acting on the apple because it is not moving. She is wrong because the resting objects have their gravitational force, which is applied by the earth.
What is force?
Energy is defined as the potential to perform a work, whether it is a simple or complex one, and each work needs a different amount of energy. If an object, such as the apple on the table, remains motionless or at rest, it gains potential energy but the force is applied on it. The substance has the kinetic energy such as a rolling apple when it moves.
The substance moves in the direction of the force applied. The movement of a substance depends on its mass and the force applied to it. If a mass of 10 kg is maintained, it will require more energy to push the substance weighing 2 kg.
Hence, she is wrong because the resting object, which is the apple, has its gravitational force.

If radio active substance that weight5600grams and half-lifeof 100years is left with 700 grams for how long has the decaying activity been undergoing?
Answer:
If you have a 120 gram sample of a radioactive element, how many grams of that element will be left after 3 half-lives have passed?
Solution
Given: mass of radioactive sample of an element, number of half-lives
Asked to Solve For: mass of radioactive element after so many half-lives
Solve:
All radioactive samples lose half of their mass after each half-life. Thus, one solution is to calculate the mass after each half-life. (This method only works if you are asked to solve for a whole number of half-lives). Let the passing of time equal to one half-life be represented by and arrow, →. Then the solution is:
120 g → 60 g → 30 g → 15 g
If you want to solve for any number of half-lives, including fractional half-lives, then you use the equation: amount remaining = (12)n(amountatstart) , where n= number of half-lives. Then the solution is:
amount remaining = (12)3(120g)=15g

8. All of the following are true of surface currents except (1 point)
Othey are influenced by wind.
Othey can exist in large lakes.
Othey are found in the top 1,300 feet of the ocean.
Othey have the same movement as thermohaline currents.
Water current involves surface or deep water circulation. Surface currents are influenced by winds and occur in the top 1313 feet of depth. Statement 4 is false. They have the same movement as thermohaline currents.
-----------------------------------------------
Many different factors can produce water currents in lakes and oceans. Some of these factors are
winds, temperature, salinity, earthquakes, and storms.When talking about water circulation, there are two main types of movements,
Surface circulation, which occurs from 0 to 400 meters deep (up to 1313 feet aproximatelly)Deep circulation, which occurs at depths that super 400 meters.Surface circulation is closely related to horizontal water movements, while deep circulation is related to vertical ones.
→ Horizontal water movements
They are produced by the action of different winds on the surface. Superficial winds, influenced by the Coriolis effects, are responsible for most of the marine currents. Trade winds push the water surface forward western direction in the equator, while western winds produce currents that move water to the east at higher latitudes.By the Coriolis effect, water masses are deviated to the west or the east, depending on the hemisphere, resulting in large clockwise circular turns in the Northern Hemisphere and the opposite direction in the Southern Hemisphere.Warmer currents travel from the tropics, along the continental margins, carrying warm water to higher latitudes, and as they do so, these water masses get cooler, producing cold currents.
→ Vertical movements
They can be related to density, salinity, and temperature. Variation of these factors causes thermohaline currents, which move water vertically, transporting cold water with nutrients from the bottom to the surface.According to this resumed framework,
→ Surface currents ⇒ horizontal movement ⇒ up to 400 m depth ≅ 1313 feet
→ Deep currents ⇒ vertical movement ⇒ more than 400 m depth.
OPTIONS
they are influenced by wind ⇒ TRUE they can exist in large lakes ⇒ TRUE they are found in the top 1,300 feet of the ocean ⇒ TRUE they have the same movement as thermohaline currents ⇒ FALSE------------------------------------------------------------------------

Discuss several limitations imposed on science and scientists in problem-solving and hypothesis-testing.
Science depends on the formation of hypothesis to solve complex problems in the world.
Science is empirical in nature. The experiments in science must be carefully controlled. This limits the ability of science to test certain hypothesis which are not amenable to carefully controlled experiments. As a result of this there are certain things that can not be incontrovertibly proven be science.
Also, the formulation of hypothesis and hypothesis-testing could be influenced by the biases of the scientist involved in problem solving. This influences his results and is an obvious limitation in the scientific method.

Disruption of the active site of an enzyme would most likely result in which of the following? A decreased ability of the enzyme to bind allosteric regulators. A decreased ability of the enzyme to bind products. A decreased ability of the enzyme to bind substrates. An increase in the rate of the reaction catalyzed by the enzyme
Answer: A decreased ability of the enzyme to bind substrates.
Explanation: Hope this helps!
The disruption of the active site of an enzyme would most likely result in the enzyme's decreased ability to bind to the substrate. Hence, the third statement is correct.
What is an enzyme?
Enzyme is a biocatalyst that reduces a substrate's activation energy and converts it to the product. The enzyme has an active site at which the substrate binds. After binding to the active site of an enzyme, the substrate is converted into products by making or breaking a few bonds. If active site doesn't function then substrate can't bind.
Apart from the active site, the enzyme has other sites, such as the allosteric site. At this site, allosteric regulators bind. These allosteric molecules may be activators or repressors. Activator allosteric regulators increase the enzyme function, while repressor allosteric regulators repress the enzyme function by reducing the catalysis. Activators increase the catalysis rate.
Hence, the disruption of the active site of an enzyme would most likely result in the enzyme's decreased ability to bind to the substrate. Hence, the third statement is correct.

Nonmetals
I wanted to let the other guy get brainliest, and now they can :)
Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.
What are nonmetals?A nonmetal is an element that lacks the characteristics of a metal. It is characterized by what it is not rather than by what it is. It doesn't have a metallic appearance, can't be formed into a wire, bent, or pounded into shape, has a low melting or boiling temperature, and isn't good at conducting heat or electricity.
On the periodic table, nonmetals make up a small portion and are mostly found on their right side. The one exception is hydrogen, which appears in the upper left corner of the periodic table and behaves as a nonmetal at ambient temperature and pressure. Hydrogen is projected to behave like an alkali metal under high pressure.
Therefore, Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.

5. A man heterozygous for a mutation in a gene that causes sickle cell disease (an autosomal recessive disease, i.e. not sex linked) who is color blind (a recessive X- linked condition) is expecting a child with a woman who is also heterozygous for the sickle cell disease gene. The woman has normal vision, but her father was colorblind. What is the probability that their child (of either sex) will have sickle cell disease AND be colorblind?
The probability that their child will have sickle cell disease and be colorblind would be 1/8.
Both diseases are independent of each other.
So, considering the sickle cell alone: Let A be normal cell and S for sickle cell. A heterozygous man and woman would both be AS.
AS x AS
AA AS AS SS
Probability of their child having sickle cell = 1/4
Considering the color blindness alone, let a represents color blindness allele and A for normal eyes allele. A colorblind man would have [tex]X^aY[/tex] genotype while a woman with normal vision but with a colorblind father would be heterozygous with [tex]X^AX^a[/tex] genotype.
[tex]X^aY[/tex] x [tex]X^AX^a[/tex]
[tex]X^AX^a[/tex] [tex]X^aX^a[/tex] [tex]X^AY[/tex] [tex]X^aY[/tex]
Probability of their child being colorblind = 1/2
The probability of their child having sickle cell and being colorblind = probability of having sickle cell x Probability of colorblind
