Why is the following molecule nonpolar and hydrophobic?
The image shows a polymer composed of a chain of 14 carbon atoms. The first carbon atom is bound to three hydrogen atoms. The next 12 carbon atoms are bound to two hydrogen atoms. The final carbon atom is bound to a carboxyl group.
The carbon and hydrogen atoms share electrons equally.
The glycerol molecule in fats contains a carboxyl group.
There are exactly three fatty acid chains present in each fat molecule.
There is an unequal distribution of hydrogen and oxygen atoms.
Answer:
a
Explanation:
The following molecule is nonpolar and hydrophobic because the carbon and hydrogen atoms share electrons equally. The correct option is A.
What are nonpolar and hydrophobic?Non-polar molecules are those which can not be dissolved in water. These molecules have ends that are not dissolved in water. Hydrophobic is a quality of the substance that is not dissolved in water or repels water.
The image shows a polymer made up of three hydrogen atoms are bonded to the initial carbon atom. Two hydrogen atoms are joined to the next 12 carbon atoms. A carboxyl group is attached to the last carbon atom.
Since charges fluctuate, a momentary dipole moment exists in a so-called nonpolar molecule.
Thus, the correct option is A, The carbon and hydrogen atoms share electrons equally.

FORENSIC SCIENCE!! When analyzing a strand of hair, investigators would first try to collect DNA from which general location?
Inside of the hair strand
The medulla
The hair tip/point furthest from the scalp
The point closest to the scalp
Answer:
The correct answer is - The point closest to the scalp.
Explanation:
In order to analyze a strand of hair investigators need to collect the DNA. To analyze a strand of hair the DNA must be nuclear DNA which can be found at the root of the hair near the scalp as the point, hair attached to the scalp there are cells that can provide the nuclear DNA. Any other section or the part of the hair strand does not contain the nuclear DNA so analyze DNA would not be possible.

Is starch a simple sugar molecule?
Answer:
yes because Most carbohydrates can be broken down by digestion into glucose and these are the carbohydrates
Explanation:
Answer:
Simple vs Complex Carbs. Carbohydrates are sugars that come in 2 main forms – simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed – as well as it's chemical structure

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.
Answer:
I think it’s B
Explanation:
Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.
What is the rise in biodiversity in woodland ecosystem?In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.
Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.
Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.
Therefore, The rise in biodiversity makes the ecosystem more sustainable.

Can a species switch from being an r-species to a K-species or visa versa?
Answer:
as causas de las extinción de una especie pueden ser muchas, como la destrucción de su hábitat natural, la caza o captura de animales exóticos, la contaminación, la deforestación (la desaparición de los bosques por la tala de árboles) o el cambio climático, que son consecuencia de la intervención de los seres humanos. Aunque esto también puede relacionarse con distintos fenómenos naturales como inundaciones, incendios, o la llegada de enfermedades.

decreased, so did the carrying capacity.
B. The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population
decreased.
C. The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there
was less food available, reducing the carrying capacity.
D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.
Answer:
C seems to be the most reasonable answer.
Explanation:
The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

How are elements in the same period in the periodic table alike?
A. They have the same atomic number.
B. They have the same number of electron shells.
C. They have similar chemical properties.
D. They have the same atomic mass.
Answer:
C
Explanation:
The elements in the same period in the periodic table alike and they have similar chemical properties. Thus, option C is correct.
What is Groups and Periods in Periodic Table ?In periodic table there are 18 vertical column which is called groups which are arranged from left to right in the periodic table. In periodic table there are 7 horizontal rows which is called periods.
Elements in the same family or group have a similar chemical properties because they have the same number of valence electrons. In group one all the alkali metals have one valence electrons in the outermost shell.
Thus from the above conclusion we can say that Elements in the same family have a similar chemical properties because they have the same number of valence electrons this statement is true about elements on a periodic table in the same group.
Therefore, The elements in the same period in the periodic table alike and they have similar chemical properties. Thus, option C is correct.
