Answer:
B
Explanation:
- electroporation or microinjection actually pokes holes in the cell membrane so DNA can be introduced directly into the cell. Microinjection requires the use of a fine needle to deliver nucleic acids to individual cells.
- you can insert DNA fragments or genes into a plasmid vector, creating a recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities.
Thus, leaves question B as the Not method

Why was the potato easier to balance on the ruler when the forks were added
Answer:
More weight.
Explanation:
Explanation:
In these amazing science experiments you will learn how to balance a potato, fork and a pencil on a table so that only the tip of the pencil is touching the edge of the table. Think its impossible? Not if you follow the directions and do some experiment on your own. Plus these seemingly gravity defying experiments are fun to do.

Answer: ..
Explanation:
Discuss what is respiration and why is it important.
Answer:
Respiration is the chemical process by which organic compounds release energy.
Explanation:
Respiration is important because it produces energy that is essential for the normal functioning of the body. Respiration provides cells with oxygen and expels toxic carbon dioxide. Some energy released by respiration is also in the form of heat.

how do the germinal discs differ between the eggs?why?
Answer:
Germinal disk (blastoderm) -- a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc. The embryo develops from this disk, and gradually sends blood vessels into the yolk to use for nutrition as the embryo develops.

What most likely caused the change in the distribution of fur colors in the graphs shown?
A. The medium-colored rabbits were not able to reproduce.
B. A predator showed up that was better at hunting medium colored rabbits
C. Medium-colored rabbits moved away from the area.
D. Medium-colored rabbits were not able to find food efficiently.
Answer: D
Explanation: I think it is d because of process of elimination. A is not reasonable because the graph 2000 goes up and down so not being able to reproduce would not fluctuate. The other two choices the. Are close but not sensible to how the graphs are structured. Therefore best choice is option is D.
Which of the following would be least likely to occur as a result of the lack of living space?

B. A decreased number of mountain lions can result in inbreeding which can cause genetic issues in the population . C. Mountain lions fight over the smaller number of possible mates and end of injuring or killing each other.
D. Food becomes scarce and animals starve

2. A population of salamanders has two colors, blue and white. Blue is the dominant color and white is recessive. The frequency of the white allele is 36%. What percentage of the salamander population is white?
The percentage of the white salamander population is 16%.
Hardy-Weinberg Equilibrium EquationThe genotypic frequencies within a population can be expressed by the binomial (p + q)² = 1, which can be developed and represented by the following equation:
p² + 2pq + q² = 1p = frequency of the dominant allele;
q = frequency of the recessive allele;
p² = frequency of the zygous dominant genotype;
2pq = frequency of the heterozygous genotype;
q² = frequency of the zygous recessive genotype.
Also according to the equation presented (p² + 2pq + q² = 1), we will have the following distribution of genotypes:
CC = 0.36 = 36%Cc = 0.48 = 48%cc = 0.16 = 16%Learn more about recessive allele in brainly.com/question/844145
5. What would be the harm in having a captive animal intended for release imprinting on its human handlers?
Answer:
If we release a captive animal imprinted on human then the animal won't recognize other animals of its species as same as itself . It won't mate with its species rather it would try to mate with humans. It would not behave normally. The behaviour would not be typical of other members of its species.
Which is not an example of evolution?
A. The long necks of giraffes.
B. The different beaks of Galapagos finches
C. Changing color of peppered moths
D. The disappearance of the dodo
Answer:
D. The disappearance of the Dodo.
Explanation:
The answer should be D. because evolution is how organisms or things change over a period of time. The Dodo becoming extict or diappearing does not have anything to do with evolution.

Anyone who has/is currently getting a degree in environmental science from an online university, which school is it and what has your experience been. Thank you!
Answer: I go to Pomona College and they are amazing at teaching so many things about the environment through science and in my opinion I think you should go. My experience so far is amazing and if you are curious and want to know something new this is where to go:)
Explanation:
when do plants use oxygen
Answer:
When there is no sunlight and they undergo cellular respiration
Explanation:
Plants respire to get energy like animals. In this chemical process, glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. See the diagram below

What is a disadvantage to Hydroelectricity?
Answer:
Water levels are lower than usual.
Answer:
Hydropower can impact water quality and flow. Hydropower plants can cause low dissolved oxygen levels in the water, a problem that is harmful to riparian (riverbank) habitats and is addressed using various aeration techniques, which oxygenate the water.
Where does the energy to create ocean waves come from? What happens to waves once the wind stops? How does the Coriolis effect impact Earth?
Answer:The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.
Explanation:
I hope this helps
Volent miko<3
Answer:
Coastal currents are affected by local winds. Surface ocean currents, which occur on the open ocean, are driven by a complex global wind system. To understand the effects of winds on ocean currents, one first needs to understand the Coriolis force and the Ekman spiral.
If the Earth did not rotate and remained stationary, the atmosphere would circulate between the poles (high pressure areas) and the equator (a low pressure area) in a simple back-and-forth pattern. But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect. It is named after the French mathematician Gaspard Gustave de Coriolis (1792-1843), who studied the transfer of energy in rotating systems like waterwheels.

mushrooms get their nutition by
Answer:
Most mushrooms are considered saprophytes — they get their nutrition from metabolizing non living organic matter. Nutrients and other essential compounds are stored in their bodies, and when there is enough material stored and the conditions are right they start to fruit or produce mushrooms.

O species
O invasive
O specialists
O generalists
