Rudolph is famous for his glowing red nose
What could possibly make his nose emit light?
Why would the glow of his nose be red?
Please don't answer just for points, I need this to be done by today! Thank you for your time.
Answer:
Bioluminescence is the production and emission of light by a living organism
Explanation:
Bioluminescence occurs through a chemical reaction that produces light energy within an organism's body. For a reaction to occur, a species must contain luciferin, a molecule that, when it reacts with oxygen, produces light. ... Many organisms also produce the catalyst luciferase, which helps to speed up the reaction.

the other liquid waste product in cellular respiration is
Answer: During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.
Explanation: Hope dis helps :)))))
Answer:
the waste products are carbon dioxide and water

A scientist discovers a new type of eukaryotic cell that does not contain mitochondria. As a result of this difference, the scientist predicts that the cell is most likely to be different from other eukaryotic cells in which way? A.In the way it releases energy from food molecules B.In the way it maintains homeostasis with its environment C.In the way it reproduces D.In the way it evolves
Answer:
A. In the way it releases energy from food molecules
Explanation:
This is because, the mitochondria is the part of the cell that produces energy from food molecules. Since this cell does not contain a mitochondria, it will thus affect the way it releases energy from food molecules.

Answer:
C
Explanation:
Photosynthesis and cellular respiration differ in which of the following
ways?
O The main source of chemical energy in cellular respiration is water.
The energy conversion in cellular respiration takes place in the chloroplast.
O The main source of energy in cellular respiration is glucose.
The final product of cellular respiration is electromagnetic radiation.
Answer:
the main source of energy in cellular respiration is glucose.
Explanation:
photosynthesis creates glucose out of co2 h2o and sunlight. while cellular respiration is almost exactly the opposite.
The ways in which photosynthesis and cellular respiration differ is that the main source of energy in the case of cellular respiration is glucose. Hence, Option C is the correct answer.
The photosynthesis and cellular respiration processes are interlinked with a significant relationship. The products of one process act as reactants in the other. Some of the significant differences between both processes are mentioned as follows:
Photosynthesis takes place only in phototrophs such as plants and algae while cellular respiration can take place in all the living forms. Photosynthesis completely takes place in chloroplasts and cellular respiration in Mitochondria. Glucose is made by the process of photosynthesis while glucose is utilized in cellular respiration to make molecules of ATP.Thus, we can conclude that photosynthesis and cellular respiration differ specifically by the main source of energy. Hence, option C is the correct answer.

Man has a haploid life cycle.
True
False
Man does not have a haploid life cycle. Haploid life cycle is observed in most of the single-celled organisms. Thus, the given statement is false.
What is haploid life cycle?
The haploid life cycle is the simplest type of life cycle. It is found in most of the single-celled eukaryotic organisms. Organisms with a haploid life cycle spend the majority of their lives in haploid forms as haploid gametes. When these haploid gametes fuse, they form a diploid zygote.
The life cycle of Man is an example of diploid life cycle. The human life cycle involves a mature human cell (2n), eggs are produced by meiosis in the ovary of a woman, and sperms are produced by meiosis in the testis of a man. The eggs and sperm combine in fertilization to form a diploid zygote (2n).

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reproductive cells, which are sperm and egg cells
Chromosomes in "most cells of the organism"(somatic cells) are diploid and the chromosomes are grouped in pairs while the chromosomes in reproductive cells are not paired so there are half the number that would be found in somatic cells so the sex cells are haploid.

Answer:
The correct answer is - cell membrane.
Explanation:
Cell membrane or plasma membrane is the outer structure that enclosed the cell-matrix and cell organelles and acts as a barrier to the substances and things to move in or out of the cell and allows only specific substances and molecules to move in and out of the cell.
If the cell membrane is not performing its function properly it might result in blocking the various nutrients and other essential molecules to move in and metabolic substances to move out of the cell.
