Explanation:
Look through the lesson lol i know your school
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.

1. Meiosis is two divisions of a reproductive cell’s nucleus. It occurs in a continuous series of steps. Compare AND contrast the steps of meiosis I to meiosis II.
2. Describe mutation. Give EXAMPLES where mutations could be harmful, beneficial, or neutral.
Answers
Answer:
1. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
2. Answer! A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. I hope it helps! :)

4. Transcribe and Translate a Gene. How is mRNA different from DNA? (Hint read the side-bar on this page for help) What is the correct starting position for translation? Write the amino acids used to assemble your protein in the order below. Where does translation take place?
Answers
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.

Give three differences between parenchyma and selerenchyma?
Answers
Answer:
Parenchyma cells have thin primary walls and usually remain alive after they become mature while Sclerenchyma cells have thick lignified secondary walls and often die when mature.
Parenchyma forms the "filler" tissue in the soft parts of plants while Sclerenchyma provides the main structural support to a plant.
Parenchyma cells are usually loosely packed with large intercellular space while Sclerenchyma cells has no intercellular spaces between the cells.
Parenchyma: (1) “Found in” These type of cells are present in every soft part of the plant. (2) “Type of cell” Unspecialized and living cells. (3) “Cell shape” There are various shapes of the cells, but generally, they are isodiametric.
Sclerenchyma: (1) “Found in” it is found in mature parts of the plants or trees. (2) “Type of cell” specialized, matured and dead cells. (3) “Cell shape” Sclereids, elongated and fibre shape.

What is Inheritance pattern?Genetic variation distribution in families is characterized by inheritance patterns. Predicting disease risk in a patient's family requires an understanding of these patterns.
Conditions brought on by pathogenic variations in a single gene are referred to as monogenic or Mendelian conditions.
Depending on the pattern of inheritance, a gene may be influenced by either one or both alleles.

Avoid UV radiation by wearing sunscreen.
Avoid UV radiation by using a tanning bed.
Answers
Answer:
Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations.
Explanation:
The most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.
What is DNA mutation?DNA mutation may be defined as the process that induces sudden, stable, and inheritable changes in the genetic material of organisms through various factors.
The UV radiations are the most potent physical agent that induces DNA mutation. But in order to avoid such kinds of DNA mutations from UV radiation one must be required to be protected from such kinds of harmful radiation with the help of sunscreen.
The UV radiation induces DNA mutations by causing the dimerization of the thymine base, which significantly alters the whole sequence of genetic material.
Therefore, the most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.
