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.

Explanation:
The first line of defense involves which structure(s)?
OT-cells
O skin
O blood
OB-cells
Answer:
skin
Explanation:
The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.
As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

Read each of the answers below carefully: Which statement best describes the cell cycle? a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase. b. Cells grow and develop during the mitotic phase. Cells reproduce during interphase. c. The nucleus of the cell divides during interphase. The cytoplasm of a cell divides during the mitotic phase. d. The nucleus of the cell divides during the mitotic phase. The cytoplasm of a cell divides during interphase.
Answer:
a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
The statement best describes the cell cycle - a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
HOPE THIS HELPED <3
Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.

In this lab, you will explore the microscopic process of building proteins from RNA. Instead of working with variables, you will focus on the steps of that process. What investigative question will you answer by exploring this process? Write your question below.
Answer:
What steps occur inside the cell to build proteins?
Explanation:
Hope this helped
RNA is the single-stranded molecule that determines the sequence of amino acids to build up the polypeptides. Transcription and translation are the two processes through which the DNA will convert into the sequence of amino acids.
In the lab, the steps of processes are being focused on. The investigatory questions of the experiments include:
How are the proteins formed using the information given by the RNA molecule?How are the processes of central dogma, transcription, and translation are involved in the formation of protein?What are the steps involved in the building up of proteins within a cell?Thus, the investigatory question in a laboratory experiment generally starts with 'how' and 'what.'
