Genetic engineering can be used to disrupt specific genes in the genome of an organism. Predict how the browning of apple slices
adell [148]

Answer: Fruit will not brown. Browning requires a functional enzyme.

Explanation:

Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>

Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.

If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.

Flowers of orchid species Ophrys bombyliflora look and smell like female bumblebees. This attracts the male bumblebees flying ne
balandron [24]
I would say A) Coevolution because the two species would evolve in response to one another. Flowers and their pollinators must evolve together. For example, if the flower has a mutation that no longer attracts the bumblebees, it will not reproduce. Then the hummingbird would have to find a new food source.

Which of the following statements correctly state(s) the location or function of the cells in the epidermis and dermis? Select a
coldgirl [10]

Answer:

Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.

Explanation:

Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.

Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
