what is biotechnology

Answers

Answer 1

Biotechnology is the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms. The exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.


Biotechnology can be defined as the controlled and deliberate manipulation of biological systems for the efficient manufacture or processing of useful products. The fact that living organisms have evolved such an enormous spectrum of biological capabilities means that by choosing appropriate organisms it is possible to obtain a wide variety of substances, many of which are useful to man as food, fuel and medicines. Over the past 30 years, biologists have increasingly applied the methods of physics, chemistry and mathematics in order to gain precise knowledge, at the molecular level, of how living cells make these substances. By combining this newly-gained knowledge with the methods of engineering and science, what has emerged is the concept of biotechnology which embraces all of the above-mentioned disciplines.

Answer 2

Biotechnology is the use of organisms and biological processes to create technological applications that serve human needs, particularly in the areas of agriculture, medicine, and food science.

Biotechnology is the application of technology to manipulate the genetic material of living organisms to produce new products or improve existing ones. This field combines various aspects of biology with cutting-edge technology to create products that benefit humanity in fields such as agriculture, food science, and medicine. Through methods like genetic engineering, scientists can create crops with higher yields, plants that can resist pests and advanced medical treatments like gene therapy.

Biotechnology is not a new concept; in fact, humans have utilized this science in simpler forms throughout history, such as in the making of cheese, wine, yogurt, and beer using microorganisms like yeast. However, modern advancements allow for more precise alterations at the genetic level. This enables the production of antibiotics, the cultivation of cell cultures for research, and the potential for curing genetic disorders through gene therapy.

State the genotypic and phenotypic ratios that would result from a cross between two YyRR pea plants

Answers

Geno: 0:4:0


Pheno: 3:1

Final answer:

The genotypic ratio for a cross between two YyRR pea plants is 1:2:1 (YY:Yy:yy), and due to yellow being dominant, this results in a phenotypic ratio of 3 yellow-seeded to 1 green-seeded plants.

Explanation:

The genotypic ratio resulting from a cross between two YyRR pea plants refers to the proportion of different genetic combinations in the offspring. Since the R allele is always present in its dominant form (RR), we only need to consider the crossings for the Y and y alleles. A self-cross of Yy can be shown in a 2 × 2 Punnett square, leading to possible allele combinations of YY, Yy, yY, or yy. Accounting for the different ways to obtain the Yy genotype and knowing fertilization is random, we expect a genotypic ratio of 1:2:1 (YY:Yy:yy).

When considering phenotypes, both YY and Yy result in yellow seeds, while yy results in green seeds. Applying the sum rule of probability, we expect phenotypic ratios of 3 yellow to 1 green because the YY and Yy offspring are phenotypically identical. This anticipated outcome—based on large sample sizes similar to Mendel's experiments—is a phenotypic ratio of 3 yellow:1 green.

Which adaptation is unique to insects among all protostomes?

Answers

I think it is the ability to move by flying. Protostomes are one of the two groups of animals having a true body cavity (coelom) and are believed to share a common ancestor. They include the mollusks, annelids, and arthropods. In this animals the blastopore becomes the mouth. Other characteristics include, they have true tissues, they have bilateral symmetry, and that the mouth develop before the anus in during embryonic development.
Final answer:

The respiratory system of insects, characterized by a network of tracheae and spiracles that allow direct gas exchange with tissues, is a unique adaptation among all protostomes. This system is highly specialized for both terrestrial and freshwater environments.

Explanation:

The adaptation that sets insects apart from all other protostomes is their respiratory system. This system is comprised of a network of hollow tubes called tracheae that allow air to flow directly to the tissues for gas exchange. The tracheae open to the outside world via small openings known as spiracles. Other protostomes might have similar systems, but this specific tracheal system of ventilation is unique to insects.

It’s fascinating to know that although this system works extremely well in terrestrial environments, it still functions effectively in freshwater aquatic environments. You can find numerous species of aquatic insects in both immature and adult stages that possess this unique adaptation. Even if some insects inhabit the surface of marine environments, none complete their entire metamorphosis in salt water, further highlighting the specialization of the insect respiratory system.

#SPJ12

The varied shapes of bird beaks exemplify adaptive evolution through natural selection, optimizing feeding efficiency for different diets and environments.

The different shapes of bird beaks are examples of adaptive evolution driven by natural selection. Each bird species has evolved a beak shape that best suits its specific feeding habits and ecological niche. This adaptation allows them to efficiently gather and consume their preferred food sources, whether it be seeds, insects, nectar, fish, or other dietary items.

For instance, birds with long, slender beaks like hummingbirds are adapted for feeding on flower nectar, while birds with short, sturdy beaks like finches are specialized for cracking seeds.

Similarly, birds like pelicans have long, hooked beaks suited for catching and consuming fish, while birds like woodpeckers have strong, chisel-like beaks for drilling into wood to find insects.

The diversity of beak shapes among bird species reflects the diverse range of environments and ecological niches they inhabit. Over time, variations in beak shape within populations can lead to the formation of new species through the process of speciation.

Thus, bird beaks serve as a classic example of how natural selection acts on anatomical traits to optimize survival and reproduction in different environments.

Why is freshwater a limited resource?

A. Used water can be cleaned and filtered mechanically and chemically back to freshwater.

B. They hydrologic cycle constantly replenishes the global freshwater supply.

C. There is very little of it; most of the water on earth is salted.

Answers

C. There is very little of it; most of the water on earth is salted.
Final answer:

Freshwater is a limited resource mainly due to the fact that only a tiny fraction of Earth's water is freshwater, and a significant portion of that is inaccessible. Although reclaimed water and the hydrologic cycle continually restore the freshwater supply, human consumption, pollution, and the majority of water being salted result in freshwater's limited availability.

Explanation:

Freshwater is considered a limited resource primarily because, while the Earth is largely covered in water, only about 2.5% of that water is freshwater. Furthermore, of that small percentage, a significant amount is locked away in ice caps and glaciers, inaccessible for human use. This leaves a fraction of the Earth's total water supply available for consumption, making it a limited resource.

Moreover, although we do have systems in place for cleaning and filtering used water back to freshwater, those processes can be expensive and logistically challenging. Similarly, while the hydrologic cycle does continually replenish the Earth's freshwater supply, it does so at a rate that is often outpaced by human consumption and pollution.

So, even with technological advancements and natural processes working to continually restore our freshwater supply, the fact that the vast majority of the Earth's water is salted, combined with increasing human consumption and contamination, results in freshwater being a limited resource.
