Explanation:
The differentiated cell has specific transcription factors that are present in the cell and cause specific genes to be transcribed. Option E is the correct answer.
What is cell specification?Cell specification is the process by which a cell determines its fate. After specification, a cell's gene pattern changes. Some genes that are present in euchromatin regions are expressed, and as a result, this cell expresses specific proteins and RNA.
After the zygote is formed, it undergoes a cleavage process to form multiple cells by mitosis. The cells then specify and receive their fate, such as some converting into nervous cells, others into epithelial cells, and still others into blood cells.
This change in structure and function is due to the expression of special genes in DNA. Though all cells have the same genetic content, some genes are present in euchromatin regions and some genes are present in heterochromatin regions. Genes of euchromatin are expressed.
Hence, option E is the correct answer, as the cell produced specific transcription factors.

Describe the different types of traits that exist.What factors can affect these traits?
Answer:
Cardinal traits, central traits, and secondary traits.
Explanation:
There are three types of traits according to the Gordon Allport which organized traits into three levels that is cardinal traits, central traits, and secondary traits. Factors that affect these traits are the environmental factors as well as genetic factors. Some of these traits acquire by an individual through inheritance while on the other hand, other traits can get by the people through the exposure to environment that leads to the presence of that traits.
If u and y are two variables such that
du
= 4v - 3. and u = 5 when v = 2,
du/dv
find u in terms of v.
Answer:
5
Explanation:
The value of u is 5 in term of v by putting the value o v which is 2 in the formula that is du = 4v - 3. Putting the value of v = 2 we get, du = 4(2) - 3. --- du = 8 - 3. ---- du = 5. we are able to solve the question due to the presence of v value. If the v value is not present then we can't find the value of u in term of v. So we can conclude that the value of u in term of v is 5 if we put the value of v in the formula.
All of these events are characteristic of an El Niño event except:
A- the Midwestern United States experiences more rainfall than usual.
B- the usual South America-to-Southeast Asia winds ease.
C- South Africa, Japan, and Canada experience warmer than usual weather.
D- ocean surface temperatures are lower than usual.
E- storms form off the coast of California.
Answer:
B- the usual South America-to-Southeast Asia winds ease.
Explanation:
The usual South America-to-Southeast Asia winds did not blow from west to east because of El Nino event. In normal condition, the winds blow easterly from South America-to-Southeast Asia which means from west to the east direction but due to El Nino event, the wind blows is reversed which causes the blowing of winds towards westerlies which means from east to the west direction so the usual blowing of winds from South America-to-Southeast Asia did not occur.

If the birth rate and death rate are balanced in a population, how might a population increase in size?
I
Answer:
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow
Explanation:
Natural increase in a population occurs where Birth rate is greater than death rate. ... Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline
The population will be doubled by immigration. The correct option is C.
What is immigration?When an animal settles down in a habitat because it has resources nearby or because it is a good fit for them, this is referred to as immigration.
When an animal emigrates, it's because its habitat is no longer perfect for it and it needs to move to a new location with a better habitat.
It is the quantity of members of the same species that have entered the habitat during the time period under examination from outside the habitat.
To immigrate means to move permanently to another country. To migrate is to move, much like wintertime birds. Depending on the viewpoint, one can either migrate, immigrate, or emigrate.
Immigration can increase the size of a population if the birth and death rates are equal.
Thus, the correct option is C.

Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants.
feedback mechanism is a form of system regulation that occur in living organs which help to return or restore the body to it's original normal internal condition for sustainability of living. It is also called homeostasis.
Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants because nitrogen helps to increase the concentration of chlorophyll which is the green pigment house in chloroplast that aid the increase of photosynthesis rate in plants.
Therefore,Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants.

A student is planning an investigation of the effect of population size on an ecosystem. She plans to use a five-gallon fish tank with ten goldfish for her investigation. How should the student perform her investigation? A. She should limit the amount of food given and observe the results. B. She should add a predator fish to the tank and observe the results C. She should continue to add more goldfish to the tank and observe the results D. She should change the temperature of the water in the tank and observe the results.
Answer:
C
Explanation:
Because the student is observing the effects on the population, so it would make more sense to add more fish to the tanks to see how they would get effected.
A student is planning an investigation of the effect of population size on an ecosystem, so she should continue to add more goldfish to the tank and observe the results, as in Option C.
What is the population size of an ecosystem?In the student's investigation, the goal is to observe the effect of population size on an ecosystem using a fish tank with goldfish. The student has already decided to use a five-gallon fish tank with ten goldfish for the experiment, so by adding more goldfish to the tank, the student can observe the effect of population size on the ecosystem. As the population of goldfish increases, the competition for resources such as food, oxygen, and space will also increase. This can lead to changes in behavior.
Hence, she should continue to add more goldfish to the tank and observe the results, as in Option C.

Chemical reactions of fossil fuels
Difference between biomass and fossil fuels
Comparing biomass with other renewable
energy sources
Making energy choices locally
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.
