A. Constant movement of the air through the convection cycle.
B. Temperature differences between the poles and the equator.
C. The Sun heating different parts of the Earth unevenly.
D. All of the above
Choose one correct answer.''
Answer: Hewo, there! your answer is Below
D. All of the above
Explanation:
Wind is the movement of air caused by the uneven heating of the Earth by the sun. ... Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth's surface toward the Equator to replace the heated air.
Hope this helps you
Have a great day!!
Answer:
Hello! Your answer would be, D) All of the above.
Explanation:
The energy that drives wind originates with the sun, which heats the Earth unevenly, creating warm spots and cool spots. Two simple examples of this are sea breezes and land breezes. Sea breezes occur when inland areas heat up on sunny afternoons. That warms the air, causing it to rise.

Answer:
H dominant
Explanation:
If a trait has two possible outcomes and one is expressed over the other, it means one is dominant and the other is recessive. Dominant traits are expressed when there is at least one dominant allele (can be Aa or AA). Recessive traits are expressed only if both the alleles are recessive (has to be aa). If the trait is being expressed over the other one it is a dominant trait.

What is the correct equation for the breakdown of ozone? please answer quick
Answer: This electricity converts the oxygen molecule to ozone. Our equation is as follows: 3O2 + energy = 2O3.
The correct equation for the breakdown of ozone can typically occur in a series of two steps known as the destruction of ozone. It is illustrated thus;
Cl + O3 ⇒ ClO + O2ClO + O ⇒ Cl + O2The net reaction of the above process is the reaction of an oxygen atom with an ozone particle to form two molecules of oxygen.
The catalyst in this reaction is chlorine because it undergoes changes as the process continues while ozone is removed in the process. In the presence of sunlight, atomic oxygen is formed.
This entire process is referred to as the destruction of ozone.

The fossil record indicates that in some cases reasonably well-defined species appear suddenly and remain unchanged for a long time before they become extinct. This phenomenon is referred to as
Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.

2. How much is the average temperature at depth of 10 km of earth surface?
A) 200 °C
C) 650°C
B) 900°C
D) 20°C
The average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.
What is the average temperature?An average temperature may be defined as the annual mean temperature of any geographical location which is estimated approximately by the average temperature of the maxima and minima for the warmest and coldest months of the year.
It is the principle that the increase in the depth below the surface of the earth ultimately leads to the rising of average temperature. This is due to the process of apparent heat.
It may be possible that higher or lower temperatures also occur. but the average temperature at depth of 10 km of earth surface should approximately remain 200°C. It is a factual type of question.
Therefore, the average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.

Ecological Succession: Transformation of Communities over Time
Why does secondary succession occur faster than primary succession?
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
Answer:
Soil with nutrients is already present. Seeds are present from earlier occupants, brought in by wind, and/or germinate after fire.

The antibiotic rifampicin blocks transcription in many bacteria. In the presence of the antibiotic, adding sigma factor has no stimulating effect on RNA synthesis. A footprinting experiment on a rifamycin treated sample shows that the polymerase remains located at the promoter site in the presence of eNTPs and Mg2 ion. What step of transcription is rifamycin likely to block
Answer:
transcription initiation
Explanation:
Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:
1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.
2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence
3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).
In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the allele B leads to blue beetles. Heterozygous beetles are red and blue spotted. A heterozygous beetle mates with a red beetle. What is are the genotypic and phenotypic frequencies of their offspring? Please show all of your work. (2)
Answer:
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
Explanation:
Given that:
The allele → R = Red beetles
The allele → B = Blue beetles
Since the gene color shows a codominant allele
The Red Beetle = RR
The blue beetles will be = BB
The heterozygous beetle will be = RB
∴
The punnet square showing the crossing of RB × RR is:
R B
R RR RB
R RR RB
The result shows that we have two red beetles and two heterozygous beetles.
Hence;
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
