What is the difference in the structure of the enzyme RNA Polymerase between eubacteria and archaebacteria?
Eubacterial RNA Polymerase has 10-20 subunits.
Archaebacteria's RNA Polymerase has 4-5 subunits.
Archaebacteria's RNA Polymerase has 8-12 subunits.
Eubacterial RNA Polymerase has 5-10 subunits.
Answer:
Archaebacteria's RNA Polymerase has 8-12 subunits.
Explanation:
I just finished the exam and it was the right answer
Archaebacteria's RNA Polymerase has 8-12 subunits.
What is Archaebacteria?Halophiles (microorganisms that may live in extremely saline settings), methanogens (microorganisms that create methane), and thermophiles are all types of archaebacteria (microorganisms that can thrive extremely hot environments).
They diverged from eukaryotes and eubacteria. Because they are prokaryotes and lack a distinct cell nucleus, they resemble eubacteria. They differ in terms of ribosomal organization, the presence of introns, and the nature or composition of the membrane.
They are comparable to eukaryotes in that they share many metabolic pathways and genes with them, especially those involved in transcription and translation. Archaea also have genes that are similar to those of eukaryotes.
Therefore, Archaebacteria's RNA Polymerase has 8-12 subunits.

O reducing population growth along the coastline,
O None of these are correct.
building desalination plants to maintain freshwater supplies for coastal populations
Answer:preventing or reducing pollution from the land and from streams
Explanation: This is true because these said streams and other bodies of water can flow into the ocean
The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.
What is pollution?Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.
Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.
For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.
Therefore, the correct option is A, reducing population growth along the coastline.

Describe the positions of high and low pressure and the temperature of the land and water to explain how land breezes form.
Answer:
The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
The menstrual cycle
Explain whether the female is pregnant (3 marks).
Answer:
According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.
Explanation:
The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.
During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.
In the case of a pregnant woman:
Estrogens continue to increase after ovulation, produced by the ovaries and placenta.Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta.Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.The diagram represents the normal cycle of a woman who is not pregnant.
Spirilla, a type of bacteria, are
mitochondria

prokaryotes
Answer:
its Hey now children, settle down. Today we're going to talk about life. There are six ways to know you're alive for sure:
1. Living things have cells.
2. They use stimuli to maintain a homeostasis.
3. They have DNA.
4. They reproduce.
I said no laughing!
5. They live, thrive and die.
6. They use energy.
Ayo, first things first:
There's three different types of living things on the Earth.
Ya heard?
There's organisms with one cell,
Whose life functions are performed by organelles.
And green plants use photosynthesis,
A chloroplast converts sunlight and lives with it.
And last are the animals, listen,
Cells, tissue, organ-to-organ system.
And they're unique; I can't lie, homes,
Only animal cells contain lysosomes.
But all cells contain ribosomes.
They make proteins, the building blocks, I suppose.
Yo, but don't get caught slipping
On the oils and the fats, a.k.a. the lipids.
Cells need fuel — they break carbohydrates
Into ATP, adenosine triphosphate.
Alright y'all! Cell theory has three parts:
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life in all organisms.
3. All cells come from existing cells.
On top of that, they all have a cell membrane surrounding the cytoplasm, and most plants and bacterium have a cell wall.
Now let's travel to the center of the cell,
The nucleus, where nucleic acids are held.
They form DNA, the genetic code,
And multiply by mitosis if you let it go.
It's incredible, like the duty is
Of mitochondria — extract energy from nutrients.
And did I mention, the spot they make the lipids in,
Is the ER, or endoplasmic reticulum?
And the Golgi complex is next to it,
Delivering the products of the ER — excellent!
To hit the exit, you could use diffusion,
The membrane will pass in or out of solution.
Of all movement, the cell has control,
Disposing of waste in a vacuole.
And that can use active transport,
To either squeeze out or ingest something, so plan for it.
Alright y'all! Now who in here can spell flagella? And who knows where the word came from, "cell"? Anybody know that it's Latin? Cellula means "small room." Now before y'all go, let me remind you: Don't forget to respect the building block of life. Give it up for cells, y'all! Alright, class dismissed. Class dismissed. Get your flagella out of here.

Answer:
Cohesion: Water is attracted to water
Explanation:
Cohesion is the name of this sticking together of like substances. The material can be more or less coherent, based on how drawn the molecules of the same substance are to each other. Bonds of hydrogen allow water to be highly attracted to each other. Water is rather cohesive, thus.

Communicate- Explain how you would calculate the wavelength of a wave if you knew both the wave's speed and frequency.
Answer:
If you want to calculate the wavelength of a wave, then all you have to do is plug the wave's speed and wave's frequency into the equation. Dividing speed by frequency gives you the wavelength. For example: Find the wavelength of a wave traveling at 20 m/s at a frequency of 5 Hz.
The wavelength of a wave can be calculated with the help of frequency and speed of wave. Wavelength is the ratio of speed of wave and the frequency of wave.
What is a Wave?A wave is a disturbance in the medium which carries energy without a net movement of particles. It may take the form of the elastic deformation, a variation of the pressure of the waves, electric or magnetic intensity, electric potential, or temperature.
The wavelength of the wave can be calculated with the help of the speed of wave and the frequency of wave.
Wavelength = Velocity of the wave/ Frequency of the wave
λ = v/ f
