The diagram shows two solutions separated by a membrane. Water molecules can cross the
membrane but solute molecules cannot. What name is given to this type of membrane?
Answer:
partially permeable
Explanation:
A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules. Partially permeable membranes are also called selectively permeable membranes or semi-permeable membranes. They let some substances pass through them, but not others.

Passive transport definition
Answer:
Passive transport definition is - the movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
Explanation:
Answer:
Passive transport is a kind of membrane transport in which chemicals are moved across cell membranes without the need of energy. Passive transport uses the second law of thermodynamics to drive the movement of substances across cell membranes rather than cellular energy, as active transport does.

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.

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.

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.

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
= 1/4 x 1/2
= 1/8

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
