Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.pls mark brainliest

Mrs. Tuff is now insistent that Tommy sits in her lap and as she speaks to Tommy he begins to cry more and refuses to open his mouth. Mrs. Tuff continues to tell Tommy that it won't hurt and if he only opens his mouth, he will get a toy. What steps can you take now to get Tommy to cooperate?
Solution :
Tommy is a young boy and is feeling afraid to open his mouth and show it to Mrs. Tuff. Something had stuck into his mouth and he is finding it difficult to eat anything and it is paining a lot.
Mrs. Tuff is insisting tommy to sit on her lap so that she could examine him but he refuses to open his mouth and cries loudly. I told Tommy that it is for his own good and he should listen to Mrs. Tuff and open his mouth so that Mrs. Tuff could treat him. By this Tommy will get relief from his pain and he will better.
I also insisted Tommy to open his mouth as it will cause him any pain. I gave something to Tommy so he can get distracted and open his mouth. Mrs. Tuff also told him that he will get a toy if he opens his mouth.
This is how I got Tommy to cooperate with Mrs. tuff.

Why are fungi more like animals than plants?
PLEASE HELP ME
Answer:
Hey mate.....
Explanation:
This is ur answer.....
However, unlike plants, fungi do not contain the green pigment chlorophyll and therefore are incapable of photosynthesis. That is, they cannot generate their own food carbohydrates by using energy from light. This makes them more like animals in terms of their food habits.

A bacterial cell wall is composed of: A) A polysaccharide consisting of a single type of monosaccharide unit and cross-linking oligopeptides. B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.
Answer:
B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.
Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.
Which of the following can a UAV do?
1. Provide information about geography
2. Provide information about soil nutrients

Grass (that is healthy) looks green because Group of answer choices it emits green light and absorbs other colors. it reflects green light and absorbs other colors. it absorbs green light and emits other colors. it transmits green light and emits other colors.
Answer:
it reflects green light and absorbs other colors.
Explanation:
The term pigment derives from the Latin pigmentum, which means the substance that produces color.
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.
Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.
The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.
The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

Un tractor tira de un remolque cargado sobre un camino plano libre de fricción, con una fuerza horizontal constante de 440 N. Si la masa total del remolque y su contenido es de 275 kg, ¿Qué aceleración tiene el remolque? Formula a utilizar : Ʃ F = m . A *
Answer:
1,6 m / s ^ 2
Explanation:
De las leyes de Newton;
Fuerza = masa × aceleración
masa = 275 kg
Fuerza = 440 N
Aceleración = Fuerza / masa
Aceleración = 440N / 275Kg
Aceleración = 1,6 m / s ^ 2

Over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. Scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. However, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. These global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. Chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. In some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. If these resistant individuals continue to survive and prosper, new resistant populations might emerge. This would be an example of ________.
Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.
Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.
