This image shows the ionic bond between sodium and chloride in NaCl (table salt), and the covalent bond between oxygen and hydrogen in H2O (water.) How are the bonds different?molecular structure
Question 3 options:
The hydrogen transfers its electrons to oxygen in water; sodium and chlorine in salt share their electrons.
The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
The oxygen transfers its electrons to hydrogen in water; sodium and chlorine in salt share their electrons.
Answers
Answer:
B. The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
Explanation:
The bonds between sodium and chloride in NaCl (table salt), and oxygen and hydrogen in water are different as sodium and chloride in NaCl have ionic bond and oxygen and hydrogen in water have the covalent bond.
Sodium transfers an electron to chlorine in sodium chloride (NaCl), so that they both have full outer shell and form ionic bonds. sodium and chloride ions exerts electrostatic force on each other and bond together with ionic bonds.
The hydrogen and oxygen atoms in water have covalent bonds because they are bonded by sharing electrons. Both hydrogen and oxygen atoms share unequal electrons with each other and form V-shaped water molecule.
Hence, the correct answer is "B."

The table to this question is unclear, the detailed tabular form of this data has been attached.
The answer is BAR GRAPH
Explanation:
Bar graph or chart is one of the means statistical data is represented or displayed. A bar graph uses bars positioned horizontally or vertically to represent data. A bar chart is used to show comparison between the values of different categories. The length of each bar shows the degree of the measured data.
According to the data provided in the question, a comparison between the critically endangered species and endangered or vulnerable species in % of different types of species is described. Using a BAR GRAPH, the x-axis of the graph will contain the different types of species while the y-axis will contain the quantity in percentage (%) of the endangered or critically endangered species.
Note that, two different bars of different colors will be used to represent whether the species is endangered or critically endangered.

Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival. Which of the following adaptations would be more useful for an animal in a marine biome than for an animal in a freshwater biome? a. flippers and flattened tails b. smooth, nearly furless body c. streamlined body d. tolerance to high levels of salinity Please select the best answer from the choices provided A B C D
Answers
Answer:
I think it is D.
Explanation:
The reason I think this is salinity is how salty the water is and an animal that can tolerate high levels of salinity will thrive well in marine biomes.
The adaptation that would be more useful for an animal in a marine biome than for an animal in a freshwater biome would be tolerance to high levels of salinity.
Marine biomes are characterized by a high level of salinity. The saline environments are often hypertonic to the cells of organisms. Thus, organisms will ordinarily lose water to such environments and die as a result of dehydration.
Hence, organisms that will successfully inhabit marine biomes must find a way to tolerate the hypertonic environment. One of such adaptations is the possession of salt glands in the body.

Which of these organisms are in a trophic level that receives a larger percentage of the energy captured by the producers than the percentage received at the bats’ trophic level?
Mountain lions
Ground squirrels
Snakes
Hawks
Answers
Answer:
D. Ground squirrels
Explanation:
Took the test
Ground squirrels are at a trophic level that receives a larger percentage of the energy they consume as producers than the percentage received at the trophic level of bats. So, the correct option is B.
What is Trophic level?The trophic level of an organism is defined as the position it occupies in a food web where a food chain is a succession of organisms that eat other organisms and are themselves eaten. An organism's trophic level is the number of steps from the beginning of the chain.
Organisms at the lower trophic level have the highest percentage of energy compared to those at the higher trophic level that have the lowest percentage of energy. For the example above, if a ground squirrel has 100% energy, the next trophic level will receive 10% of the total energy from a lower trophic level that only has 10%, other higher trophic levels only receive 1%, then the next level Only 0.1%
Therefore, the correct option is B.

Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his skin to his brain. This information would travel via GSA neurones.
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.

Answer:
c. Retrograde motion of the planets as they moved across the sky.
Explanation:
Ancient Greek philosophers were extremely intelligent people who propounded some ideas that have helped shape science to what it is today.
They had evidence for the spherical shape of the earth, the link between lunar phases and oceanic tides, and the existence of exoplanets, however, they did not have evidence for the retrograde motion of the planets as they moved across the sky because they believed that if the Earth moved around the Sun, then they would be able to see the stars from divergent points along Earth's orbit.

. Jack and Jill are thinking about starting a family and they come to you with a question about a rare recessive genetic disease called Alpers Syndrome. Alpers causes progressive neurodegeneration in infants and children and is usually lethal within the first 10 years of life. Jack's grandfather had a brother die of Alpers Syndrome, while Jill has no family history of the disease. If the frequency of heterozygotes for Alpers is 1 in 2000 in the general population, what is the chance that Jack and Jill will have a child with Alpers Syndrome? (Be sure to completely reduce your answer.)
Answers
Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome

Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
