What did researchers discover about the genetic mutation causing lactase persistence?
Researchers discover about the genetic mutation causing lactase persistence is that they are located next to the lactase gene in a non-coding regulatory region (a "switch").
The lactase enzyme's continuous activity as an adult is known as lactase persistence.
The LCT gene provides instructions for making an enzyme called lactase. This enzyme helps to digest lactose, a sugar found in milk and other dairy products.
Since lactase's sole purpose is to digest lactose in milk, most mammal species see a significant decline in the enzyme's activity after weaning.
The genetic selection of those who can digest lactose results in the lactase persistence trait, which is more prevalent in populations that keep cattle and raise dairy products.

As a forest becomes fragmented into smaller and smaller patches, the effects of fragmentation on these patches might result in the Edge effect.
What are the effects of Fragmentation?The fragmentation of habitat is a serious issue all across the planet. Even a small reduction in the total area of wild areas is unacceptable.However, it can compromise the integrity of entire ecosystems when fragmentation is present.The so-called "edge effect" can also result from fragmentation. Some species prefer moist, shaded environments, including some mosses and lichens. As a forest area gets smaller, it's possible that they'll become exposed to too much light or a drying wind and vanish.The species with the largest home ranges can survive in a healthy forest because it is big enough for them. They can be quite vulnerable to fragmentation because they are typically the top predators.Many species may be unable to travel if their natural habitat is fragmented, leading to their extinction.Hence, the Edge effect may occur as forest fragments into ever-tinier patches as a result of the impacts of fragmentation on these patches.

The Phagocytic specialists are neutrophils, monocytes and macrophages.
What is Phagocyte?A phagocyte is a special kind of cell that can take in and occasionally digest foreign substances like bacteria, carbon, dust, or dye. By producing vacuoles (cytoplasmic extensions that resemble feet) around the foreign particle, it engulfs foreign materials by extending its cytoplasm into pseudopods. While the bacteria are still inside the vacuole, where digestion occurs, phagocyte enzymes are produced, protecting the phagocyte from any poisons that may be present in the ingested bacteria.Monocytes (macrophages) and neutrophilic leukocytes (microphages), two different subtypes of white blood cells, are phagocytic. Small, granular leukocytes known as neutrophils soon appear at the site of a wound. About three days after infection, monocytes start to appear.They are bigger cells with a large, kidney-shaped nucleus that scavenge for bacteria.

What if the light intensity was 1000, what do you predict the ATP production percentage would be?
Main Answer:
ATP Production will not change as change in wavelength because it depends on no. of photons striking the surface means intensity of light.
Explanation:
ATP Production is depend upon intensity of light and not on wavelength of light.
No. of electrons involved in ATP Production depends on intensity of light.
If the light intensity is about 1000, then it will not positively affect ATP synthesis. Because enzymes do not function properly, it may harm photosynthesis.
What Role Does Light Play in Photosynthesis?The sunlight acts as a catalyst for the photosynthesis process and promotes the production of ATP (energy), glucose, and oxygen. The sunlight breaks the water molecule and forms the electron. This process is called photolysis of water and takes place in the thylakoid membrane. This occurs in the thylakoid membrane's Photosystem II (PS II).
Electrons move from photosystem II to photosystem I. The movement of the electron generates the proton gradient across the membrane. Due to the higher protons inside the lumen of the thylakoid, these move to the outer side, and as a result, ATP synthase makes ATP. If such a bright light shines on these complexes, the enzymes will stop working and ATP synthesis will suffer.
Hence, an increase in light intensity would have a negative impact on ATP production.
