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.

In C3 cycle one carbon compound is accepted by?
Answers
Answer:
The correct answer is - RuBP.
Explanation:
In calvin cycle or C3 cycle there is only one carbon compound present or enter in the cycle is carbon dioxide which is enters through stomata and move into stoma of chloroplast. It is the site of of the C3 cycle.
In calvin cycle energy used to reduce 3-phosphoglyceric acid to produce glyceraldehyde-3 phosphate which result in generation of the RuBP that accepts the CO2 from the air to attached with RuBISCO.

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.
Osmosis is important to cells because _______ *
cells contain fluids that are mostly water
cells are filled with fluids that are mostly sugar
cells need to be kept cool
cells need food
( PLEASE ANSWER THIS ASAP!!!) Thanks!!
Answers
Answer:What is the main function of osmosis? Osmosis helps in stabilizing the internal environment of the organism by balancing the levels of water and intracellular fluids. Also, the nutrients and minerals enter the cell by osmosis which is necessary for the survival of cells.
Explanation:
Osmosis maintains the osmotic pressure in cells. the answer to this question is options A and B.
Osmosis is essential for the cells due to two reasons:
1. Cells are made up mostly of water-based fluids. The process of osmosis involves the movement of water molecules from a region with a lower concentration of solutes to an area with a greater concentration of solutes through a semipermeable membrane. This aids in preserving the equilibrium of water within and outside the cell, ensuring that the cell remains hydrated and performs as intended.
2. Sugar-based fluids are the main component of cells' fluids. Osmosis also affects how much sugar and other solutes are present inside cells, helping to control their concentration. Osmosis will cause water to enter the cell if the concentration of sugar inside the cell is higher than the outside, diluted the sugar, and maintain equilibrium.
Therefore the correct answer is options a and b.

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.
Water is an adhesive substance. This means that water particles
A. are attracted to other types of particles.
B. are repelled by other water particles.
C. are attracted to other water particles.
D. are repelled by other types of particles.
Answers
Answer:
A
Explanation:
are attracted to other types of particles.
Adhesion is the term for the attraction of substances between distinct phases. It uses the attraction of water to other polar compounds, as an illustration, hence option a is correct.
What is the characteristic of water?Cohesion is the tendency of particles to cling together, it uses the attraction of water molecules to one another.
Water has a characteristic called cohesion in which water molecules form bonds with one another. As a result, surface tension develops and raindrops start to form.
Water molecules can interact with other molecules through adhesion, this enables water to adhere to surfaces like windows and other things.
Therefore, water is a strong adhesive that adheres effectively to many different materials, hence option a is correct.
