Nebulae are different luminous regions of the interstellar medium that can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.
What is dust?All the stuff between stars is referred to as interstellar matter by astronomers, and the complete collection of interstellar matter is referred to as the interstellar medium (ISM). Some interstellar material is gathered into massive clouds that are each referred to as a nebula.
Tiny pieces of solid matter drifting about in the region between stars make up cosmic dust. It's not like the dust you find in your home; instead, it has tiny particles that range in size from collections of just a few molecules to grains that are 0.1 mm in size.
Therefore, an interstellar medium can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

what is the problem with organizing organisms taxonomically purely based on their physical traits
Answer:
See the answer below
Explanation:
The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.
What evidence supports a conservation law?
Carbon dioxide becomes glucose and oxygen during photosynthesis.
Hydrogen is made from the breakdown of carbon dioxide during photosynthesis.
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Glucose and oxygen become carbon dioxide and water during photosynthesis.
Question 4(Multiple Choice Worth 4 points)
Answer:
it is c
Explanation:
C. Glucose and oxygen become carbon dioxide and water during photosynthesis.
Law of conservation:
A conservation law is a statement used in physics that says that the amount of something does not change in time.
In terms of Law of conservation of mass:
The "law of conservation of mass" is the conservation law that says that the amount of mass is always conserved, even if it is changed into another form.
During photosynthesis, plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.Therefore, correct options that supports a conservation law is option C.

Is a chicken egg biotic (living) or abiotic (non-living)? *
biotic (living)
abiotic (non-living)
Answer:
its biotic
Explanation:
Chicken egg is biotic.
What are biotic or abiotic components?
Biotic components are living organisms while abiotic components are nonliving organisms. All biotic components are living components of ecosystem. Bacteria and birds, animals are living components.
Abiotic components are non living components. sunlight, water and temperature are the non living components. Biotic factors are producers, herbivores and omnivores.
Abiotic components are physical and chemical components that act on the living components. In chicken cell the yolk which is living cells.
Biotic components also include the waste from living things and dead organisms. Earth have many biotic components. The surface of Mars has no biotic components.
Therefore, Chicken egg is biotic.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.
Answer:
No, because he used different soils.
Explanation:
which liquid will cause bean plants to grow faster.
He watered the plants with equal amounts of liquid and measured their height every other day.
The plants are in the same pots with different soils and placed in the same location.

Does natural selection act on individual or does it act on something else ?
Answer:
huh
I don't know
Answer:
Yes and no
Explanation:
Natural Selection is the process of organisms adapting to the environment around them so yes individuals are effected through them adapting to the changes and they later pass their good traits to their offspring, and eventually the individuals who don't adapt die off, but the natural selection as a whole is just the process.

Answer:
C
Explanation:

Hope this helps ;)
The process that expresses the information encoded by DNA and RNA is Transcription and translation, so option A is correct. Transcription is the process by which the genetic information stored in DNA is transcribed into RNA.
Transcription is the process by which the genetic information stored in DNA is transcribed into RNA. It involves the synthesis of an RNA molecule using one strand of DNA as a template. The resulting RNA molecule, known as messenger RNA (mRNA), carries the genetic information from the DNA to the site of protein synthesis. Translation, on the other hand, is the process by which the information encoded in mRNA is used to synthesize a specific protein. It takes place in ribosomes, where transfer RNA (tRNA) molecules interpret the genetic code on the mRNA and bring the corresponding amino acids to assemble the protein chain.
