Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance
Answers
What we already know:
All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)
So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex. That means that the gene codes for more than just the sex.
Building on that knowledge:
Sex-Related Inheritance that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas Non-Sex-Related Inheritance is carried on the other thirty chromosomes that the individual also carries.
Sex-Related inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.
Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

asap!!! A researcher illuminated a filament of cyanobacteria with light that passed through a prism, thus exposing different segments of cyanobacteria to different wavelengths of light. He found that the bacteria in the green light changed in color from green to red after multiple weeks of exposure but were still reproducing at the same rate. What can you conclude about the change in pigmentation of the cyanobacteria exposed to green light?
1.) More chlorophyll a was produced in response to the green light exposure
2.) The cyanobacteria were dying and were changing color in response
3.) Red light instead of green light was being absorbed by the chloroplasts
4.) More red photosynthesis pigments were produced to absorb green light
Answers
Answer:
#4.. More red photosynthesis pigments were produced to absorb green light
Chlorophyll, carotenoids, and phycobiliproteins, as well as additional classes like scytonemin, which are more focused on cyanobacterial cells' protection, are the three main classes of photosynthetic pigments that stand out in cyanobacteria. Thus, option D is correct.
What are the characteristics of cyanobacteria?Many plants depend on cyanobacteria for their wellbeing and development.
Being able to transform inert atmospheric nitrogen into an organic form, like nitrate or ammonia, makes them one of the very few types of organisms that can do so.
Cyanobacteria are microscopic, photosynthetic organisms that are classified as bacteria.
They were once known as blue-green algae. Since dense growths frequently color water green, blue-green, or brownish-green, they were previously referred to as blue-green algae.
Therefore, More red photosynthesis pigments were produced to absorb green light.

Ivan reads a story about a population of mice that become stranded in a dark jungle. Some mice are dark brown, while others are white. According to the process of natural selection, predict which mice would be more successful living in a dark jungle. Explain natural selection and your prediction.
Answers
Answer:
The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.
The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.
What is natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer
Answers
Answer:
Temperate deciduous forest
Explanation:
The temperate deciduous forest will have more organic matter concentration in it.
Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.
Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.Do you believe your conscious mind is simply a function of brain activity, or is it a non-physical material substance?

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?
Answers
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

Choose the words or phrases that correctly complete the sentence. Two boys are holding onto the ends of a long piece of string, and they move it up and down to make a wave. They begin to move the string faster and faster. When they move the string, the energy (remains the same / increases / decreases) and the frequency (decreases / increases / remains the same). Group of answer choices increases, increases remains the same, remains the same decreases, decreases increases, decreases
Answers
energy increases frequency decreases :)
When two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.
How are energy and frequency of waves related to one another?The energy and frequency of waves are always directly related to one another. It means that when energy increases, frequency increases. When energy decreases, the frequency decreases.
Now, according to the context of this question, when two boys begin to move the string faster and faster, the energy gradually increases with an increase in frequency as they both are directly related to one another.
Therefore, when two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.
