False, the neural layer of the retina do not prevents excessive scattering of light within the eye. Rods can only see only one color, and they work best in dim light.
The neural retina, which consists of several layers of neurons coupled by synapses, is supported by the outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are two different types of photoreceptor cells (rods and cones). Cones control the high-acuity vision required for tasks like reading as well as the sense of color via a variety of opsins, working best in well-lit surroundings. The pupillary light response and the entrainment of circadian cycles depend on the photosensitive ganglion cell, a third type of light-sensing cell.

What are the 3 most common causes of death as you get older?
The 3 most common causes of death as you get older are:
Cancer Heart disease InjuryHeart failure, cardiac attack, coronary artery disease, or heart arrhythmia are all examples of heart disease. These diseases can cause the heart to beat inefficiently and interfere with your circulation. Strokes can result in paralysis, speech issues, swallowing difficulties, and immobility. The most major risk factor for stroke is high blood pressure (hypertension), but diabetes, high cholesterol, and smoking also raise the risk.
Drug overdoses, automobile accidents, poisonings, and falls are all potentially fatal. 12 Simple falls in the elderly can result in fractures that induce immobility and impairment, as well as hasten mortality. Balance problems, deteriorating vision, or slower reflexes may all contribute to an increased risk of accidents in adults 65 and older.
Exercise programs might help you maintain your strength and improve your balance. Other things you can do to reduce your chances of falling are to keep your eyeglass prescriptions up - to - date, to rise carefully from a sitting posture, and to wear rubber-soled, flat shoes.

Can a hormone turn a gene on or off?
Yes, a hormone can turn a gene on or off.
Hormones are molecules that act as chemical messengers that travel through the body and bind to specific receptor sites on the surface of cells. When it binds to the receptor site, it triggers a gene to either be turned on or off. This can alter gene expression and ultimately affect the structure and function of the cell.
For example, hormones like estrogen, testosterone, and insulin can bind to receptor sites and activate specific genes. This can result in changes in the cell such as cell differentiation, growth, and metabolism. Ultimately, hormones can have a powerful effect on gene expression and significantly impact the health and development of an organism.

What are the three types of gene regulation?
The three types of gene regulation are transcriptional regulation, post-transcriptional regulation, and post-translational regulation which controls the initiation and rate of transcription, stability, and transport of RNA, and modifications of proteins respectively.
There are three main types of gene regulation: transcriptional regulation, post-transcriptional regulation, and post-translational regulation.
Transcriptional regulation: This type of regulation controls the initiation and rate of transcription, the process by which the genetic information in DNA is copied into RNA. It involves the binding of regulatory proteins, such as transcription factors, to specific sequences near the promoter of the gene.Post-transcriptional regulation: This type of regulation takes place after transcription has occurred and is responsible for controlling the stability and transport of RNA molecules. It can involve processes such as alternative splicing, RNA editing, and RNA decay.Post-translational regulation: This type of regulation occurs after translation, the process of converting the information in RNA into a functional protein.

c. retinol in carrots will be transported to the eyes to prevent infections.
d. beta-carotene is stored in the eyes to be used for night vision.
The saying “Eat carrots because they are good for your eyes” is true because the vitamin A precursor in carrots activates the formation of rhodopsin in the eyes.
What happens to rhodopsin in light?Light activates rhodopsin by isomerizing the chromophore to a fully metabolized conformation. Activated rhodopsin initiates a biochemical cascade that evokes photoreceptor electrical responses. Retinal all-trans is eventually released from the opsin and reduced to vitamin A.
What color does Rhodopsin allow us to see?Rhodopsin is a protein found in the outer segmental discs of rod cells. It mediates scotopic vision, which is monochromatic vision in low light. Rhodopsin absorbs blue-green light most strongly (~500 nm) and thus appears reddish-purple, hence the archaic term "visual violet".

Gene regulation is how a cell decides which gene is to be expressed. This most common form of gene regulation is through transcription.
Transcription is the process of the production of an RNA strand from the DNA. The RNA strands encode a protein called an mRNA. mRNAs are formed as a result of some external factors, like a chemical signal. When a chemical signal binds to the receptor, could trigger the cell to form an mRNA. mRNAs in turn undergo translation and proteins are formed. This is gene expression.
The gene expression is regulated by various internal and external factors. The most common is transcription, the transcription factors bind to the DNA, where the protein is encoded, and mRNA is formed. Gene regulation can also happen during RNA processing, Translation, or protein modification.
