Abe drank 5712 mL (milliliters) of diet coke. His wife Martha drank 7.04L of diet coke. How much more diet coke did Martha drink
IN LITERS? SHOW YOUR WORK
Answer:
Martha drank 1328mL or 1.328 Litres more of diet coke
Explanation:
The first step in solving this problem is to convert the two quantities to the same units.
For this problem, we can choose to work in milliliters.
Converting 7.04L to milliliters
To do this we simply multiply by 1000 because 1000mL makes one Litre.
7.04 X 1000 = 7040 mL
Once the two quantities are in the same units, the next step is to subtract them.
7040 mL - 5712 mL = 1328mL
Therefore Martha drank 1328mL or 1.328 Litres more of diet coke

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation was suggests that the living organisms can come from inanimate objects, however it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.
Do ionic bonds give electrons?
Answer:
In ionic bonds, there is a transfer of electrons from one atom to another. Because of the transfer of electrons, the atoms that gain electrons become negatively charged, while the atoms that lose electrons will be positively charged. [1] If the atom has an additional electron, then the atom becomes a negative ion, known as anion. Meanwhile, if the atom loses electrons, then the atom becomes a positive ion or cation. [2] Because of the difference in charge between ions (positive ions and negative ions), the positive and negative ions will attract each other by electrostatic forces. This event is the basis of ionic bonding.

A non living thing such as a bicycle does not grow.
However, a crystal immersed in a saturated solution
may increase in size. How is this change different
from that of a living organism?
Answer:
In living organisms, the growth is permanent, and is usually due to an increase in cells. The crystal does not contain cells, and the change in size is due to a chemical process which can also be reversed using other chemical processes.

A microbiologist is attempting to determine the size of a microbial population and has employed several methods. She noticed that the direct count she obtained using a counting chamber and microscope was much higher than her estimate from doing a viable plate count. This discrepancy was encountered during multiple trials. What is the most likely reason for the discrepancy
Answer:
The options are
A. She did not correctly do the serial dilutions to the viable plate count
B. Many organisms viewed during the direct count may be dead
C. The organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism
D. The medium and growth conditions used for the viable count will not support the growth of the organisms
The answer is C. The organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism
Explanation:
The discrepancy encountered during multiple trials which involved noticing that the direct count she obtained using a counting chamber and microscope was much higher than her estimate from doing a viable plate count was most likely as a result of the organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism.

A population of bacteria sees an increase in the number of bacteria resistant to a certain antibiotic over a number of generations. This is known as ______________.
Answer: MICROEVOLUTION
Explanation: Microevolution simply means those changes in the alleles frequencies of an organism over time.
In other words,we will say that microevolution is the generation to generation change in a population's frequencies of alleles.
These changes can occur due to natural or artificial selection,
Gene flow, mutation and genetic drift.
From the question asked,when a population of bacteria sees an increase in the number of bacteria resistant to a certain antibiotic over a number of generations,it is simply known as microevolution.

What are protein structures?
The end products of the decoding process that begins with the Replication of cellular DNA are the proteins. Proteins are called the workhorses of the cell. They form all the motor and structural elements in the cell.
They also help in the catalysis of almost all biochemical reactions that take place in a living organism. These extreme ranges of functions are derived from a simple code structure that defines these diverse sets of structures.
In the cellular DNA, each of the genes codes for a unique structure of the protein. These proteins are assembled with unique sequences of amino acids.
These structures are held with each other by bonds and are folded in different varieties of three-dimensional structures. The linear amino acid sequence of the protein determines the folded shape or conformation.
Therefore the correct option is B.

what is a scientific hypothesis? what characteristics must a hypothesis have to be useful in science?
Answer:
A scientific hypothesis must meet two criteria:
Explanation:
A scientific hypothesis must be testable. A scientific hypothesis must be falsifiable. hope this helps you :) god loves you :)
A scientific hypothesis proposes an explanation for an event that happens. We can observe it but not explain it, so we suggest a possible explanation. The characteristics that a hypothesis has to have are:
TestabilityFalsability
A scientific hypothesis suggests an explanation for something that we observe in nature but can not explain. We formulate them using the format if/then. In the first part, we propose the possibility with if. In the second part, we propose the outcome with then. For example, If humans don't eat meat, then they lack Ferrum.
The two characteristics that a scientific hypothesis must have are:
Testability:Scientists have to be able to do experiments to get information and prove the hypothesis to be correct or not.
Falsability:It means that the hypothesis, after experiments and observations, can be refuted.
In conclusion, a scientific hypothesis suggests a solution or explanation. It must have the characteristics of testability and falsifiability to be useful in science.

What causes cystic fibrosis?
Answer:
Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). This gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn't work the way it should, a sticky mucus builds up in your body.

Answer:
Asexual reproduction occurs during mitosis.
Asexual reproduction is the duplication of the genetic material from a parent organism to create a new organism. In mitosis also the cell first makes the division of DNA or nucleus after that the division of cytoplasm takes place and thus the parent cell divides itself into 2 daughter cells which are like each other.
What name is given to a large network of neurons within the brainstem that is essential for maintaining wakefulness
Answer:
These are the Reticular Activating system
Explanation:
These are network of neurons that occupy lager areas of the brainstem. They are located between the brain stem and the cortex.These neurons projected anteriorly into the hypothalamus, posteriorly into the thalamus to form the ascending RAS and emerged directly into the cortex.
Generally,the RAS is made up of 4 components.These are each made up of group of nuclei .The latter are simultaneously activated by the lateral hypothalamus,which cause the release of neurotransmitters that cause the modulatory effects produced by the entire RAS
Their major function is the control of sleepiness and wakefulness in individuals.It does this with the interactions with a lot of neurotransmitters present in the brain.
Besides the above functions the RAS is also responsible for the control of focus, stability of muscles tone.
