Answer:
Today, the basis for how we classify galaxies is still rooted in morphology, or how the galaxies appear. Astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular.
Explanation:
Barred Spiral Galaxy
Barred spiral galaxies share the same features and functions as regular spiral galaxies, but they also have a bar of bright stars that lie along the center of the bulge, and extend into the disk. The bright bulge has very little activity here and contains mostly older, red stars. The bar and arms have lots of activity.including star formation.
While the classification for barred spirals is the same as it is for regular spiral galaxies, the bar must be considered as well. Short bars correlate to tighter galaxies and will be included in the designation SBa. SBb have longer bars and SBc are the longest. Most astronomers now agree that the Milky Way is a barred spiral galaxy.
Elliptical Galaxy
Elliptical galaxies can be recognized by their elongated spherical shape and their lack of nucleus or bulge at the center. Although there is no nucleus, the galaxy is still brighter in the center and becomes less bright toward the outer edges of the galaxy. Stars, gases and other materials are spread throughout the elliptical galaxy. An elliptical galaxy can be nearly round or long and cigar shaped.
It is believed that a great deal of the mass in an elliptical galaxy is due to the presence of a central black hole. These galaxies have very little activity and contain mostly old stars of low mass, because there aren’t the gasses and dust needed to form new stars.
Irregular Galaxy
Irregular galaxies are composed of gasses, dust, stars, nebulous formations, neutron stars, black holes and other elements common to all galaxies. Irregular galaxies are named so because they have no definite shape, but like all galaxies, they are in constant motion, moving outward and away from the center of our universe. Irregular galaxies are divided into two classifications: Im and IO.
Im galaxies occur most often among irregular galaxies and may show a trace of the spiral galaxy arms. IO galaxies are completely random and can be called chaotic in nature. The Magellanic clouds that border our own Milky Way Galaxy are examples of Im galaxies. Approximately 20% of our galaxies are classified as irregular

Which planet is most similar in temperature to Earth?
Answer:
It depends; If you're asking for very temporary moments on the planet, it would be mercury, because its temperature ranges from 427 degrees to -180 degrees Celcius. If you were to stand just in the right spot at just the right time, its temperature would be the same as the earth's temperature.
But if you are asking about longer periods of time, it would be Mars. Its average temperature is around -60 degrees celcius, but its summer can get up to 20 degrees celcius.

What are some methods scientists have discovered that can stop a virus from spreading in its host? (Choose all that apply)
destroy the RNA polymerase altogether
prohibit the RNA polymerase from starting initiation
stop the RNA polymerase from moving along the DNA strand.
use antibiotics to destroy the RNA polymerase before initiation
Answer:
destroy the RNA polymerase altogether
prohibit the RNA polymerase from starting initiation
stop the RNA polymerase from moving along the DNA strand.
These are the correct answers
Explanation:
A virus can be stopped from spreading in its host by destroying the RNA polymerase altogether, Prohibition so the RNA polymerase from the starting initiation, and by stopping the RNA polymerase from moving along the DNA strand. Thus, the correct options are A, B, and C.
What is a Virus?A virus is a sub-microscopic organism, which is an infectious agent that replicates only when present inside the living cells of an organism by using its replication machinery. Viruses infect all the life forms, from animals and plants to the microorganisms, such as bacteria and archaea.
Viruses can be stopped from spreading in the host body by destroying the RNA polymerase, this RNA polymerase is responsible for the multiplication of RNA from host DNA in an organism. By prohibiting the activity of RNA polymerase from initiating the replication the multiplication of viruses can be stopped. This RNA polymerase moves along the host DNA and forms new strands for the replication purpose.
Therefore, A, B, and C all are correct options.

How are chemosynthetic bacteria different from photosynthetic bacteria?
A Chemosynthetic bacteria do not require water B Chemosynthetic bacteria eat tube wormS. C. Chemosynthetic bacteria require intense sunlight
D. Chemosynthetic bacteria do not need light.
Answer:
D
Explanation:
Chemosynthetic bacteria different from photosynthetic bacteria in that Chemosynthetic bacteria do not need light and the correct option is option D.
Chemosynthetic bacteria are a type of bacteria that can produce their own energy and organic compounds without the use of sunlight. They obtain their energy by oxidizing inorganic substances, such as hydrogen sulfide or methane, and using the energy released from these chemical reactions to synthesize organic molecules.
In contrast, photosynthetic bacteria, including cyanobacteria, use sunlight as a source of energy for photosynthesis. They have pigments, such as chlorophyll, that capture light energy and convert it into chemical energy through a series of biochemical reactions.
Chemosynthetic bacteria can thrive in environments with little or no light, such as deep-sea hydrothermal vents or certain underground ecosystems. They are able to utilize chemical energy sources to sustain their metabolic processes and support their growth and reproduction.
Thus, the ideal selection is option D.

is broken?
Lysosome contents are released in a cell.
Energy is released in a cell.
Water is transported into an animal cell
Light energy is absorbed in a plant cell.
Answer:
An event that occurs when a phosphate-phosphate bond is broken in ATP is that energy is released in a cell.
Explanation:
Adenosine triphosphate or ATP is the molecule in charge of providing energy to the cell, which is necessary to perform its functions.
The energy contained in ATP depends on the high-energy bonds that bind the phosphate groups to the energetic nucleotide molecule. Through the hydrolysis of ATP, phosphate is separated from ATP, obtaining ADP, and a large amount of energy is released. This energy serves for the cell to perform its metabolic functions.
The other options are not correct because:
Lysosomes act on cellular digestion. Transport of water into the cell occurs by osmosis, through aquaporins. Light energy is absorbed in a plant cell, through photosynthesis.Which of the following best describes giant stars? A. hot, dim stars B. cool,dim stars C. hot ,bright stars D. cool, bright stars

4. How are atoms related to molecules?
Answer:
Every combination of atoms are molecules. A compound is a molecule made of atoms from different elements.
Explanation:
Atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.
What is the significance of the atoms and molecules?They are both significant because they are both the basic building blocks of matter, and atoms in a molecule are held together by various types of bonds, such as ionic bonds and covalent bonds, etc. Water molecules, for example, are made up of oxygen and hydrogen, which are the atoms that combine to form the molecule.
Hence, atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.

This monarch butterfly has orange wings. Is orange
the genotype or the phenotype? Explain
Answer:
Phenotype
Explanation:
It's phenotype because a genotype is not a physical trait; a genotype means genes. It's phenotype because it a physical trait you can see. Lets say twins look the same on the outside but on the inside they have completely DNA. This is like how some butterflies look the same with orange wings but one might have a mutation in its genes.

Which best describes the nucleus of an atom?
a. It is thee negatively charged part of the atom
b. It contains no mass.
c. it is made of neutrons and electrons.
d. It is the most massive part of the atom
Answer:
The answer is D.
I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!
Explanation:
So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.
