Explanation:
Two balloons are rubbed with fur, which creates an excess of electrons on the balloons. If the balloons are hung from flexible wires from a shared point overhead, what will happen to the balloons?
A.
They will repel one another and the angle between them will be proportional to the charge on each.
B.
They will attract one another and sustain that attraction until the charges have redistributed.
C.
They will swing like a pendulum, with the period based on the magnitude of the transferred charge.
D.
They will join at a single point where the excess charge has collected and then they will repel one another.
The genetic code is the set of instructions that
translates genetic material into proteins. This code
defines how sequences of three nucleotides specify
which amino acid will be added next during protein
synthesis. Each sequence of three nucleotides is called
A. a protein
B. a codon
C. a Mutagen
D. a DNA molecule
Answer:
DNA molecule
Explanation:
Each sequence of three nucleotides is called a codon. Therefore, the correct answer is option B.
Codons are named by the request for their bases. The three stop codons in mRNA are UAA, UAG, and UGA, where U represents uracil, A for adenine, and G for guanine. Stop codons signal the end of protein synthesis. They can be found in DNA or mRNA.
They are three-nucleotide sequences that encode a particular amino acid. During the translation process, the tRNA (transfer RNA) molecules contain anticodons that aid in the transfer of amino acids to the mRNA.
A codon is a sequence of three nucleotides in DNA or RNA, also known as a trinucleotide. It is a unit of genomic information that encodes a specific amino acid or signals the end of protein synthesis (stop signals).

1. Which of the following elements is the LEAST abundant in living organisms?
a oxygen
b nitrogen
c phosphorous
d sulfur
Answer
Sulfur is the least abundant in living organisms.
sulfur is the LEAST abundant in living organisms among the options.
Living organisms are composed of Chemical elements which constitute the build up organelles, cells, tissues, and organs.
The Chemical elements are divided into:
Essential elements : These essential elements are 11 in number ad also subdivided into the major essential elements which make up about 99% of the human body mass. They include Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. The remaining five (least essential elements) consists of Sulfur, potassium, sodium, chlorine, and magnesium which make up about 0.85% of the remaining mass. Trace elements:.The trace elements comprises of the remaining 0.15% of the human body is comprised of trace elements. Whether they may be essential for life, is still being researched for evidence.Arranging the essential chemical elements according to abundance in living orgasm we have:
Oxygen 65.0% of body massCarbon 18%Hydrogen 10%Nitrogen 3% Calcium 1.4 %Phosphorus 1.1% Potassium 1%SulfurChlorineMagnesiumWe can therefore conclude that from the question Sulfur is the least abundant in living organisms.

1. The carrying capacity for a population of deer in a forest is 300 individuals.
Which of the following is true?
A population of 300 deer will remain at about 300
A population of 100 deer will remain at about 100
A population of 500 deer will continue to grow exponentially
A population 300 deer will run out of resources and crash
The organisms found in a coral reef habitat include clownfish, seahorses, and sea grass.
2. Which of the following terms best describes these organisms?
community
biome
species
population
3.Which of these is an abiotic factor in a tundra ecosystem?
amount of sunlight
trophic levels
species richness
vegetation
Answer:
1. A population of 300 deer will remain at about 300
2. community
3. amount of sunlight
Explanation:
1. Carrying capacity is defined as the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. Therefore if a population has reached its carrying capacity, it will most likely remain at that size.
2. A community is defined as all of the populations of different species that live in the same area and interact with one another. Clownfish, seahorses, and sea grass are all different species living in an area together and interacting with each other. This example does not show a population, nor a species, nor biome, since a population is a group of organisms of the same species, and a biome is a distinct biological community that has formed in reponse to a shared physical climate.
3. Abiotic factors are non-living factors which affect an ecosystem.
How does the human brain receive messages and send signals to the body about what's happening?
Answer:
heres how
Explanation:
Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses.” Impulses rush along tiny fibers, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.

Which occurs just before a volcanic eruption?
Lava flows onto the sides of the volcano.
The expanding gases push magma through the pipe.
A pocket of magma forms beneath the volcano.
New rocks are formed as lava hardens.
Answer:
The expanding gases push magma through the pipe.
Explanation:
The activity that happens before the volcanic eruption is the expanding gases pushing magma through the pipe.
What do you mean by Volcanic eruption?A volcanic eruption may be defined as an activity that is responsible for an opening in the earth's crust through which lava, volcanic ash, and gases exit.
Before the volcanic eruption, several gases create an extreme pressure that efficiently pushes the magma through the pipe which leads to the flow of lava onto the sides of the volcano.
Therefore, the correct option for this question is B.

Explanation:
Why aren't human populations evolving to produce immune systems that are able to fight off MRSA and other "superbugs"?
Answer: There are genes that code for different cell receptors that detect foreign substances. And for the immune system to fight these superbugs, the genes encoding these receptors must mutate and evolve. Humans have a slow rate of evolution, slower than bacterial evolution. Then not only human genes mutate at a very slow rate, but insect genes mutate very fast and can improve their strategy to evade the immune system.
Explanation:
A mutation is a random change in the nucleotide sequence or in a gene, which produces a variation in its characteristics and which is not necessarily transmitted to the offspring. They occur spontaneously by the action of mutagens, which are physical, chemical or biological agent that changes the genetic information of an organism and thereby increases the frequency of mutations above the natural level. In multicellular organisms, mutations can only be inherited when they affect the reproductive cells, called gametes (egg and sperm) A consequence of mutations can be, for example, a genetic disease, or it can also be a favorable improvement such as being able to fight against a virus. However, even if in the short term mutations could detrimental, they are essential for our long-term existence becuase without mutations there would be no change, and without change life could not evolve.
The immune system is the body's natural defense against infections, such as bacteria and viruses. The body attacks and destroys invading infectious organisms by the coordinated action of cells and proteins. Any substance or compound produced by an organism is a potential antigen when it is recognized as foreign by the immune system of another organism, whether it is of the same or a different species. In addition, the genes code for different cell receptors that detect these foreign substances. And for the immune system to fight these superbugs, the genes encoding these receptors must mutate and evolve. But, humans have a slow rate of evolution, slower than bacterial evolution. Then not only human genes mutate at a very slow rate, but insect genes mutate very fast and can improve their strategy to evade the immune system. Therefore, the human population may not have mutations that improve the immune system to help it fight againts these superbugs.
