Suppose Gene 1 produces a protein involved in the development of the eye. In the simulation, what are two ways that you can prev

kondor19780726 [428]

Answer and Explanation:

A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.

Gomez found the masses of three rocks for science project .the first rock had a mess of 19.28 grams, the second rock had a mass

ziro4ka [17]

The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58

Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams

therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.

When resources are limited, explain 4 ways by which lizard species on the Bahamas Island can coexist

aliina [53]

Answer:

Explanation:

Coexistence occur when individual occupying in a particular place are able survive with limited resources.

Dispersal - some of the lizard go hunting, they disperse themselves to various places to get resources.

Stability mechanism- this happen when individual stabilizes them selves in a particular habitat dealing with

environmental variations that may occur and drift them apart.

Equalizing mechanism - they all try to be at the same pace to avoid been out compete, even though some are stronger they equalize their energy for all to manage the limited resources.

name the molecular bond present in carbohydrates that enables change in colour when using Benedict's reagent test

Helen [10]

Answer:

copper.

Explanation:

Benedict's solution is simple carbohydrates are heated, the solution changes to orange red/ brick red. this reaction is caused by the reducing property of simple carbohydrates. the copper (II) ions in the Benedict's solution are reduced to Copper (I) ions, which causes the color change.
