Answer:
The blood in the pulmonary artery is going to the heart to collect oxygen, and therefore has a low content of oxygen. So, the blood in the pulmonary artery is a violet colour because it has low oxygen. The blood in the pulmonary vein is oxygen rich, and so it gives a scarlet color.

Explanation:
Water is attracted to water and held together by hydrogen bonds. *
adhesion
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.

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.

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.

How do a chromosome, a gene, and an allele differ? How are they similar?
Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Explanation:
What is the level of organization from Allele to Cell?
Answer:
The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
What type of inheritance pattern shows both traits in possible offspring
Answer:
Codominance
Explanation:
Codominance is when two dominant traits are equally dominant, and therefore they both are expressed in the offspring's phenotype. For example, if in a flower, blue (BB) and red (RR) are codominant their offspring would be both red and blue. One of the common examples of codominance in humans is blood type, which is seen in AB blood since A and B are equally dominant.

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

if a star is making iron, is it a high mass or average mass star? explain
Answer:
It Considered to be a high mass star
Explanation:
High mass stars go through a similar process to low mass stars in the beginning, except that it all happens much faster. Then unlike low mass stars, they have enough mass that gravity contracts the core raising the temperature and carbon can fuse into neon, then neon into oxygen, then oxygen into silicon, then iron.
