Scientists have genetically engineered potato plants to produce potatoes that contain edible vaccines. Which is a disadvantage o

f the genetically engineered potatoes?
They are easier to transport and store than injectable vaccines (shots).

Answer:

They are more expensive than potatoes without the vaccine.

The genetically modified crops are produced by using the scientific procedures of genetic engineering. It involves the manipulation of the genome of these crops so as to make them disease resistant, improving the quality of the edible parts and increasing the yield of the plants. The crops are genetically modified with accuracy, precision and implementation of the technology therefore, the crops produced are expensive then the crops produce by the conventional method.

Hence, they are more expensive than potatoes without the vaccine is a disadvantage of the genetically engineered potato plants to produce potatoes that contain edible vaccines.

What is the difference between arbitrary and natural levels? Why do these matter? (4) how do archaeologists recover the smallest
Vlada [557]

Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.  

Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.  

It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.  

The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing

Define mutagen and describe how mutagens are used in genetic research.
Salsk061 [2.6K]

A mutagenic agent is any chemical, physical or biological compost that can induce a mutation in the cell's DNA, making this mutation pass to the next generation.

Mutagenic agents are widely used in the fields of biotechnology, genetic engineering, medicine and agroindustry. This is because these agents have helped in the advancement and development of new technological tools.  

In genetic research some bacteria and viruses are used by agribusiness companies to obtain transgenic beings. These mutagenic (biological) agents act as vectors of laboratory-created genes that will insert these genes into an organism to be modified. It could be, for example, a gene that will improve maize resistance against a pest. Thanks to mutagenic agents, this genetic information can be passed on to the organism, in this case, the plant.

Select the scenarios that describe an abiotic factor that is density independent. Select the TWO answers that are correct.
kotegsom [21]

Answer: Option B and C.

Heavy and continuous rains flood the land, submerging habitats.

c. Lightning strikes a tree and begins a fire that clears the land.

Explanation:

Heavy and continuous rains flood the land, submerging habitats.

Lightning strikes a tree and begins a fire that clears the land.

The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.

Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.

Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.

Therefore, Heavy and continuous rains flood the land, submerging habitats.

cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.

Where is a codon found
ICE Princess25 [194]

Answer:

A codon is found on the coding strand of double-stranded DNA and in the (single-stranded) mRNA. The anticodon is found on the tRNA and is the part that base-pairs with the codon (on the mRNA) in order to bring the appropriate amino acid to the ribosome to be added to the growing peptide chain.
