CH3CH2CH2CH3 - BUTANE.
CH3CH3 - ETHANE.
CH3CH2CH2CH2CH2CH2CH2CH2CH2CH3 - DECANE.
Explanation:
Hello there!
In this case, according to the rules for the nomenclature of organic compounds, it turns out possible for us to match the given hydrocarbons by knowing that octane is a hydrocarbon with eight carbon atoms, butane with four carbon atoms, methane with one carbon atom, decane with ten carbon atoms and ethane with two carbon atoms.
In such a way, the correct matching is shown below:
CH4 - METHANE.
CH3CH2CH2CH2CH2CH2CH2CH3 - OCTANE.
CH3CH2CH2CH3 - BUTANE.
CH3CH3 - ETHANE.
CH3CH2CH2CH2CH2CH2CH2CH2CH2CH3 - DECANE.

Which viral reproduction cycle is used by long term viruses that hide in our body until triggered
Answer:
Lysogenic
Explanation:
There are two types of viral reproductive cycles, lytic and lysogenic. Let's look at both of them:
Lytic Cycle: Ex. of a lytic virus: Influenza (the flu)
A virus injects its genetic material into a cellProteins are created by the virus to hijack the host cell's DNA, allowing the virus control over the cellThe virus uses its control over the cell to make the cell create proteins for new viruses while it replicates viral DNAEventually, the host cell bursts (dies), and new viruses are releasedThose new viruses infect other cells; the cycle continuesHere we can see that the lytic cycle wastes no time. As soon as a cell is infected, it will immediately turn into a virus factory. Now, what about the lysogenic cycle?
Lysogenic Cycle: Ex. of a lysogenic virus: E. Coli
A virus injects its genetic material into a cellThe virus's DNA/RNA inserts itself into the host cell's DNA/RNAThe host cell continues to grow and reproduce. Whenever it produces new cells (by duplicating its genetic material and organelles then splitting in two), the virus's DNA/RNA will also be duplicated and exist in the new cell.The process continues, creating more and more cells with viral DNA/RNAA factor (it can be anything from radiation to nutrient levels) will eventually trigger all infected cells to undergo induction, which is a process very similar to the lytic cycleInduction will: cause the host cells to produce proteins for new viruses until the cell eventually bursts, leading to the release of the newly created viruses (much like the lytic cycle)Those new viruses infect other cells; the cycle continuesAn easy way to remember which is which is lyslowgenic. It's cheesy, but it works!
Please comment if you have any other questions! I've attached a picture for some reference on the cycles if you need it.

Property of materials able to easily pass through
the plasma membrane
The membrane is basically semi-permeable, which means that some molecules can pass through but others cannot. Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, rapidly cross membranes.
What is a hydrophobic molecule?The term "hydrophobic" literally means "fear of water." Water is repelled by hydrophobic molecules and surfaces.
Oil and other hydrophobic liquids will separate from water. Hydrophobic molecules are typically nonpolar, which means that the atoms that comprise the molecule do not generate a static electric field.
Hydrophilic molecules are the ones that are usually attracted to water and basically dissolve well in polar solvents.
Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, cross membranes very quickly.
Because small nonpolar molecules like oxygen and carbon dioxide are soluble in the lipid bilayer, they can easily cross cell membranes.
Small uncharged polar molecules like water can pass through membranes, but larger uncharged polar molecules like glucose cannot.
Thus, these molecules can be easily passed through the plasma membrane.

Mientras se calienta una solución en un vaso de precipitados, ¿cuál es el
equipo de seguridad apropiado para tener en el banco?
Answer:
Fire extinguisher.
Explanation:
Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

on the population's adaptation
thereby passing that adaptation
to the next generation
Answer:
natural selection acts by differential survival and reproduction
Explanation:
According to the evolutionary theory proposed by Darwin (1859), selection natural can be defined as the evolutionary mechanism of differential survival and reproduction by which individuals adapt and change over time. Natural selection states that individuals better adapted to their environments will have more chances to survive and reproduce, thereby having more chances to pass their genes to the next generation. Natural selection acts on any heritable phenotypic characteristic, while selective pressure is any environmental factor that influences an individual's survival/reproduction.

Owls can be found all over the world, EXCEPT ________. *
Answer:
Owls can be found in all parts of the world except Antarctica.
Explanation:
Owls are found in many different habitats, such as deserts, forests, prairies, and even the Arctic tundra. They nest in trees, in holes in the ground, in barns, and in caves. And while many other birds migrate to warmer places during the winter, most owls do not. They live in the same place all year round. Antarctica is the only place in the world without owls because of the extreme temperatures of the ice desert, making it insanely hard for much life to exist there.

How can a chloroplast, a structure found in plant cells but not in animal cells, provide energy for BOTH plants and animals?
Answer:
Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
One important way in which the flow of energy through ecosystems is different from the cycle of matter
Explanation:
As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved.

genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.
nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
Answer:
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.During crossing-over, the genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles. Thus, the correct option is C.
What is Crossing-over?Meiosis is the cell division in which crossing-over takes place. Crossing-over results into formation of recombinants with genetic material which is different from the parental cells. Crossing-over takes place in the pachytene stage of prophase I of Meiosis I. This is responsible for the production of variations in the organisms.
Crossing over or chromosomal crossover is the exchange of genetic material during the sexual reproduction between the non-sister chromatids of two homologous chromosomes which results in recombinant chromosomes.
Therefore, the correct option is C.
