Question #21
In the field of medicine, researchers have recently designed a technique that allows them to use adult
stem cells to test the potency and safety of newly designed drugs for humans. What is the most
likely advantage of this new technology compared with other forms of drug trials?
A
It helps ensure that the shelf life of newly designed drugs is as long as possible.
B
It helps ensure that the newly designed drugs can cure all patients they are used to treat.
C
It helps reduce the demand to test newly designed drugs on animals.
D
It helps reduce the time it takes to bring newly designed drugs to the market.
Answer:
The answer is B
Explanation:
The technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.
The stem cells to test newly designed drugs for humansUse important stem cells to define the toxicity of new drugs presented results in preliminary tests. The rational use and search for alternative methods to the use of animals in scientific research is currently a worldwide concern. However, despite the stages of the scientific community, it is still not possible to open animal experimentation in the so-called pre-clinical development of new drugs and other products for human health.
With this information, we can conclude that the technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.

What two things below most affect the amount of dissolved oxygen in water?
Answer:
Dissolved oxygen levels will fluctuate with temperature
Explanation:
While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these factors interact.

Answer:
Answer is IV (Intravenous)
The abbreviations specifically require the medicine to be delivered by injection is IV means intravenous. The correct option is C.
What is intravenous medication?The term intravenous means within such a vein. Most commonly, it relates to administering medications or fluids via a syringe or cannula inputted into a vein. This allows the drug or fluid to immediately enter your bloodstream.
Intravenous fluids are liquids that have been designed especially and are infused into a vein to prevent or alleviate dehydration.
They are used in individuals of any age who are ill, injured, dehydrated as a result of exercise or heat, or undergoing surgery. Intravenous rehydration is a straightforward, risk-free procedure with few complications.
Intravenous is abbreviated as IV medications are solutions that are injected directly into the veins using a syringe or an intravenous catheter (cannula).

Imagine customers moving into and out of a coffee shop. Which situation
resembles how a reaction in dynamic equilibrium acts?
A. There are the same number of people inside the coffee shop as
outside it.
B. People enter the coffee shop at the same rate as others leave.
C. No people are moving either into or out of the coffee shop.
D. Some people sit down and drink their coffee slowly, while others
drink theirs quickly while standing up.
No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.
Option A, C, D are not a good analogy for dynamic equilibrium.

1. The colour of a tomato can be represented by RR, Rr or rr. Why do we use capital
letters for some symbols and lower case letters for others? Why are there two
symbols for one trait (characteristic)?
Answer:
The capital letter is used to show a dominant trait, while a lowercase is used to represent a recessive trait.
Explanation:
If you are to take a Mother and a Father as example, and they have 3 children, the father's brown eyes as example we can show the children with capital and lower case depending on their looks. If the Father had brown eyes and 2 of his children out of 3 have brown eyes, we can represent that as a dominant trait, so it would be R. Then, if we take the father's hair color, brown, and the mothers hair color, blonde, we can say 2 of 3 children have brown hair, so 1 of 3 children have brown hair. So we now know that brown hair is a recessive trait. 2 of 3 children have blonde hair so the child with brown eyes and blonde hair could be represented like "Rr". Hope that helps, this is just my little explanation of this!

Answer:
What are the differents parts of a bacteriophage?
The tailed phages have three major components: a capsid where the genome is packed, a tail that serves as a pipe during infection to secure transfer of genome into host cell and a special adhesive system (adsorption apparatus) at the very end of the tail that will recognise the host cell and penetrate its wall.

How do the internal structures of the tree function together to help a tree take in and lock up carbon atoms from carbon dioxide in the wood of the tree as it grows?
Answer:
CO2 is a basic element for plants because it is a key part of their nutrition. They take carbon dioxide from the atmosphere and, after the process of photosynthesis, break down the gaseous molecule to supply themselves with energy, release oxygen and incorporate carbon atoms into their tissues. The trees of the planet act as a sink, sequestering CO2 from the air and fixing carbon for hundreds of years in the form of wood. Carbon will be released after the tree dies, when it begins to decompose.The inner layer called phloem or bast , is made up of living cells and its function is to conduct the sugar-filled sap from the leaves to the rest of the tree.
Explanation:
Trees, through photosynthesis, retain CO2 that they keep in their "organism" throughout their life cycle until they decompose. In this way they convert carbon atoms in the atmosphere into glucose (what they use to grow), and exhale oxygen that they release into the environment. By photosynthesis, plants retain CO2, becoming its dry mass of 50% carbon. The CO2 that is produced inside the mitochondria during respiration ends up being released into the atmosphere after crossing multiple barriers. The CO2 emitted by a stem xylem parenchyma cell must first cross the membranes and cell wall; and once in the intercellular spaces of the trunk, it does not diffuse rapidly outwards, but is slowed down by the conductive elements of the xylem and by the cambium, the phloem and, finally, the outer cortex. In the xylem, the arrangement and structure of the conductive elements, as well as the structure of the membranes of the pits that connect the conductive elements and these radially with the parenchyma influence the permeability to the passage of CO2.
