Answer:
d. have red eyes and a wild-type copy of gene X integrated into a random location in the genome.
Explanation:
P elements are genetic mobile elements, i.e., transposons, which are highly mobile in the Drosophila germline. These transposons naturally cause a high rate of mutation in Drosophila germline cells resulted from an interstrain cross of males with autonomous P elements and females without P elements, a phenomenon known as hybrid dysgenesis. Moreover, a transposase in an enzyme required for the mechanism of transposition (in this case, to mediate the transposition of P elements which are reinserted randomly). The P elements have provided a useful mutagenesis system widely used in molecular biology and genetics research. In fly transformation, it is required to use plasmids with a P element (P plasmids) which contains a w+ (red-eye) marker and recognition sequences for the transposase. In this case, the embryos injected with P plasmids will contain all the components to insert the reporter gene (red-eye marker) and the wild-type copy of gene X into a random site of the genome.

Which ingredient is a food acid used to activate baking
soda in quick breads?
o honey
o buttermilk
Answer:
Honey
Explanation:
Technically it could be both, as they can both be acidic, but honey is lower on the pH scale, meaning it is more acidic and thus will have a larger chemical reaction with baking soda.

How is energy and matter conserved?
Matter and energy can be created into different forms.
Matter and energy can be changed into different forms.
Matter and energy can only be stored in fossils.
Matter and energy can be destroyed only by combustion.
Energy and matter are conserved as they can be changed into different forms. This is known as Law of conservation.
What is the Law of conservation of energy and matter ?
The law of conservation of matter and energy states that matter/energy is neither created nor destroyed but can only be transformed from one form to another.
When wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. This proves the law of conservation of mass. In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy. This proves the law of conservation of energy.To know more about Law of conservation here

Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.

For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages. Which statement describes a limitation of these methods? (1 point) They are no longer relevant because the fossil record is complete. They can show false relationships between organisms that are not reflected in the DNA. They are not reliable evidence of how the body structures of organisms evolved. They cannot be used to determine when species evolved.
Answer: They can show false relationships between organisms that are not reflected in the DNA
Explanation:
Okay so there is a thing called "convergent evolution" which basically means that different species coming from different evolutionary lines evolve the same traits. It's really easy to mistake convergent evolution for evolutionary similarities. From the fossil record, it's easy to see the bones of one animal and to see that they are similar to another but that doesn't prove that they are related because it's often due to convergent evolution.
They can offer false relationships between organisms that are not reflected in the DNA. Also, they don't prove they are related due to convergent evolution.
What is DNA?
There is a thing called "convergent evolution" which essentially suggests that additional species coming from different evolutionary strings become the same traits.
It's really easy to misunderstand convergent evolution for evolutionary parallels.
From the fossil record, it's easy to catch the bones of one animal and to see that they are equal to another but that doesn't confirm that they are connected because it's often due to concurrent evolution.

While investigating applications of science knowledge, Willy learned that scientists have used genetic engineering techniques to attach insulin-producing genes to bacterial DNA. These bacteria produce large amounts of scarce human hormones. Scientists predict that hormones produced by bacteria will be inexpensive and will not cause allergic reactions. (SC.7.N.1.5) Scientists developed hormone-producing bacteria because they wanted to
Answer:
develop methodologies to increase the production of hormones for human use
Explanation:
Genetic engineering refers to the manipulation of an organism's genes by using recombinant DNA (rDNA) techniques in order to develop biotechnological and biomedical applications. For this purpose, genetically engineered bacteria carrying recombinant human genes can be used for producing human hormones. For example, recombinant human insulin can be produced by using Escherichia coli strains, and this hormone can then be purified as genetically engineered bacteria grow in order to treat diabetic patients. For this purpose, a bacterial plasmid (i.e., an independent fragment of circular bacterial DNA) is cut with restriction enzymes and then the human gene encoding the hormone of interest is inserted into the plasmid. Finally, the genetically modified plasmid may be readily transferred to the bacterial chromosome and thus increase the supply of the hormone of interest for its use by humans.
