what are some sources of error found in osmosis experiment
Answer:
In the experiment it includes several separate tests and errors that can be easily occurring. One of the errors is the potato cores were not necessarily all the same weight to even begin with. However, another source of error is the cores were not exactly completley covered by the solution, which is due to the larger beaker.
Osmosis is the movement of particles from an area of higher concentration to an area of lower concentration, through a semipermeable membrane until equilibrium is attained.
There are experiments which can be conducted to prove that indeed osmosis occurs, making use of apparatus and things like potato or yam.
However, there could exist some errors during an osmosis experiment which can include:
Failure to properly use the semipermeable membraneParallax errorsThe solution not having a high enough concentration, etcPlease note that your question is incomplete and i gave you a general overview to help you get the right answer.

which animal would win in a competition:
dugong vs. colo colo opossum
Competition is an ecological relationship in which organisms of different species compete for resources like food, shelter, and light.
What is Competition?Competition is defined as the relationship between the organisms for resources, in which one of the organisms is harmed.For example, Dugong is a marine mammal, which is an herbivore and is native to the Indian Pacific Ocean. The organisms primarily graze in grasses and are found in marine waters only. Cola Cola Opossum is a mountain monkey, which is a carnivorous, nocturnal, and terrestrial organism. The organisms when competing with Dugong can win the competition as they are carnivorous and can feed on the marine mammal.
Thus, the competition between cola cola opossum and dugong can result in dugong being prey.

hi i need your help guys! Using the periodic table, fill in the following table with the number of electrons in each energy level of the element given.
n = 1 level n = 2 level n = 3 level n = 4 level
Element (maximum 2) (maximum 8) (maximum 18) -----------
Carbon- ________ ________ ________ _______
i think its
carbon- 2 (there are two in the n=1 level) 4 (there are four in the n=2 level)
i might be wrong, but hope this helps :)
Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;
n= 1 ------ 2 electrons
n = 2 ----- 4 electrons
n =3 ----- 0 electrons
n = 4 ----- 0 electrons
Carbon has the electronic configuration; 1s2 2s2 2p2.
This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
This makes a total of six electrons in carbon as shown.

Muchas especies animales son territoriales al menos durante una parte del año. Eso significa que defienden un territorio más o menos amplio en el que no dejan entrar a otros individuos de su especie. A veces, el territorio es individual, otras es de una pareja y, en otros casos, corresponde a un grupo. Explica qué distribución origina cada uno de estos comportamientos.
Answer:
Por dependencia de otros organismos y competencia.
Explicación:
Estos diferentes tipos de comportamiento se deben a la dependencia de los organismos entre sí. Algunos organismos tienen la capacidad de vivir solos y cumplir con sus requisitos de vida por lo que no permiten que otros organismos ingresen a su espacio, algunos viven en parejas y algunos organismos viven en grupos o colonias porque no pueden sobrevivir solos en ese ambiente por lo que nosotros Se puede decir que algunos organismos dependen de otros organismos y algunos pueden sobrevivir solos.

Why is increased female participation in government MOST LIKELY sign of democratization?
e )
Answer:
Explanation:
I hate to say this of my own gender, but the accusation that women often make is that men are sexist. But that is not the critical problem. The real problem is that men for centuries have held the mantle of power.
He who controls the money, controls the economy and the right to impose that power over women.
Even in the United States, where Americans are rightly proud of the democratic constitution, women were not given the same rights as men until the 19th Amendment was passed in 1920. The original constitution only granted men the right to vote, to have peaceful assemblies, their choice of religion. Women were not considered until nearly 150 years later as being worthy of being called citizen with full citizen's rights. If you can find it, you ought to read Abigail Adams' letter to her husband on this subject of women's rights. She couldn't spell but she could certainly think.
So Canada, the United States and I think Great Britain finally got around to giving women full citizenship at about the same time.
You can't classify yourself as democratic unless every person, male and female has equal rights before the law and equal rights in the society they live in.
It is not MOST LIKELY a sign of democratization. It is the basis of a democratic society.

Predict what would most likely happen to the octopus population if the number of snails decreased to near extinction in the area.
Answer:
Nothing will happen.
Explanation:
Nothing will happen to the octopus population if the number of snails decreased or extinct in the area because there are many other organisms on which octopus can feed. Octopuses feed on crabs, small fishes, clams, snails, and on other octopuses so if other food sources are available to Octopus so there is no effect on the Octopus population but if there is no other food source then the Octopus population will definitely decreases due to lack of food.

The activation of complement is effective at initiating pathogen engulfment and destruction. This immune-protective process is made possible by:
Answer:
phagocytes that have receptors for the C3b component in order to engulf and destroy pathogens
Explanation:
The complement system refers to an immune mechanism by which plasma proteins are activated by pathogens and their binding to antibodies, triggering reactions on the pathogen surface that active components with effector functions. The complement system is an essential component of the innate immune response. Phagocytic cells have receptors for the C3b component in order to bind to C3b-coated cells/particles preparatory to phagocytosis. The C3b receptor is a glycoprotein that serves to regulate the complement system by inhibiting the activation of C3 and C5 convertases which cleave C3 and C5 and thus mediate complement effector functions.

Hierarchy is a theme of biology that we see in several different topics Genetics
is one such area. Which sequence has the terms in the correct sequence from
LARGEST to SMALLEST in terms of molecular size?
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
B. Chromosome, Nucleotide, Genome, Gene, Deoxyribose
C. Deoxyribose, Nucleotide, Gene, Chromosome, Genome
D. Genome, Gene, Chromosome, Nucleotide, Deoxyribose
Answer:
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
Explanation:
According to this question, genetics as a branch of Biology is not exclusive of hierarchical basis. The following is an orderly sequence from LARGEST to SMALLEST in terms of molecular size:
Genome - Chromosome - Gene - Nucleotide - Deoxyribose
- The GENOME constitutes the whole genetic make up of an organism. This includes all the chromosomes contained in that organism.
- CHROMOSOME is the structure on which the inheritable unit called GENE is found.
- GENE is the molecular unit of inheritance which is made up of nucleotides.
- NUCLEOTIDES are monomers of nucleic acids made up of pentose sugar (dexyribose or ribose), nitrogenous base, phosphate group.
- DEOXYRIBOSE is a five carbon sugar that forms part of the structure of a nucleotide.
