Genetic engineering is best described as:
A. changing the RNA of a living thing to change its characteristics.
B. using certain genes to accomplish engineering tasks.
C. using genetic structures as examples for modern engineering practices.
D. changing the DNA of a living thing to change its characteristics.
Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
Genetic engineering is the field of science that changes the DNA of the living organism to alter its original characteristic. Thus, option D is correct.
What is Genetic engineering?Genetic engineering is the manipulation and modification of genetic makeup like the DNA of the organism by deleting, altering, and adding the nucleotide bases.
It uses various techniques and tools to alter the DNA and hence, modify its characteristics. It uses RDT and another process to manipulate the genome and produces desired traits by controlled breeding.
Therefore, genetic engineering changes the DNA of a living organism.

What gives a plant cell structure?
Answer:
The cell was first discovered in 1665 by an English scientist named Robert Hooke. While looking through a microscope, he observed tiny box-like objects in a slice of cork (bark from an oak tree) and named these boxes cells. Cells are the basic units of life, which make up all living things. This idea forms the basis of the Cell Theory. Plant cells are larger because they contain all of these structures but have some unique structures like a cell wall, vacuole and chloroplasts.
All these specialised structures are called organelles. An organelle is a tiny structure inside an animal or plant cell that has a specific function or role.
Answer:
The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders).
The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin. Cellulose is used extensively by humans for making paper. Cellulose can also be converted into cellulosic ethanol, a type of biofuel. Some animals, such as cows, sheep and goats, can digest cellulose with the help of bacteria in their stomachs. Humans cannot digest cellulose, which passes through our bodies and is better known as dietary fiber, something that we should eat to keep our waste moving as it should! Lignin fills in the spaces between cellulose and other molecules in the cell wall. Lignin also helps water molecules move from one side of the cell wall to the other – an important function in plants.

In an energy pyramid, what organisms have the most energy available? *
1.) herbivores
2.) producers
3.) carnivores
4.) top predator
Answer:
I think producers
Explanation:
In an energy pyramid, producers have the most energy available. The correct option is 2.
What is energy pyramid?A graphic that depicts the biomass or bioproductivity at each trophic level in an ecosystem is called an ecological pyramid.
An ecosystem's energy transfer from one trophic, or feeding, level to the next is depicted by an energy pyramid.
The model is a figure that contrasts how much energy different trophic levels of species use. Kilocalories are the units used to measure the energy in an energy pyramid (kcal).
The producers are located in the base of the pyramid, which is also its greatest level.
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Thus, the correct option is 2.

A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample
A 20% cytosine, 20% thymine, 20% guanine
B 30% cytosine, 209. thymine, 30% guanine
C 10% cytosine, 30% thymine. 40% guanine
D 30% cytosine, 30% thymine, 20% guanine
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.
According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
What are Bases?Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.
There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
∴ A = T : G = C.
If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.
This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.
Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

They are at different altitudes B. They are at different latitudes C. The forest gets more precipitation D. The grassland gets more precipitation
Explanation:
Deciduous forest, vegetation composed primarily of broad-leaved trees that shed all their leaves during one season. Deciduous forest is found in three middle-latitude regions with a temperate climate characterized by a winter season and year-round precipitation: eastern North America, western Eurasia, and northeastern Asia. Deciduous forest also extends into more arid regions along stream banks and around bodies of water. For the deciduous forest of tropical regions, see monsoon forest.

Oaks, beeches, birches, chestnuts, aspens, elms, maples, and basswoods (or lindens) are the dominant trees in mid-latitude deciduous forests. They vary in shape and height and form dense growths that admit relatively little light through the leafy canopy. Shrubs are found primarily near clearings and forest edges, where more light is available, and herbaceous flowering plants are abundant within the forest in the spring, before the trees come into full leaf.

The soils upon which deciduous forests thrive are gray-brown and brown podzols. They are slightly acidic and have a granular humus layer known as mull, which is a porous mixture of organic material and mineral soil. Mull humus harbours many bacteria and invertebrate animals such as earthworms.
Snails, slugs, insects, and spiders are common inhabitants of the deciduous forest, and many cold-blooded vertebrates, such as snakes, frogs, salamanders, and turtles, are also present. Birds are represented by warblers, flycatchers, vireos, thrushes, woodpeckers, hawks, and owls. Prominent mammals include mice, moles, chipmunks, rabbits, weasels, foxes, bears, and deer.

Please mark brainliest if correct. Have a blessed day. :)
One of the unique properties of water is that it has the capacity to dissolve many substances. The correct option, in this case, would be A.
Water is often referred to as a universal solvent. This is because the liquid has the capacity to dissolve more substances than any other liquid known to exist in nature.
The ability of water to dissolve a wide range of substances has been linked to its chemical and physical properties, especially its polar nature. Water molecules are polar with slightly positive and negative charges, Thus, they are able to attract other types of molecules
