Answer:
Option B, Genetic engineering
Explanation:
Biodiversity determines the different types of species living in a given area. Hence it is incorrect
Bioremediation is basically a waste management system in which organisms are used to break down hazardous substances into less toxic substances. Hence, it is also incorrect
Hemodialysis is used to remove or filter out wastes and water from blood. Hence, it is also incorrect
Genetic engineering is used to produce organism with desired trait by altering their DNA and hence the associated Phenotype. Thus, it is the correct answer
Hence, option B is correct
Answer:
Genetic engineering
Explanation:
Genetic engineering is a technique in which DNA of desired gene is isolated from the body of an organism and inserted into the body of host cell. The host cell then develop organism or species with the characteristics of desired gene. The organism with genetic manipulation are called genetically modified organism (GMO).
Genetic engineering has many application such as human growth hormones, mass-produce insulin, follistim (for treating infertility), monoclonal antibodies, increasing productivity of animals and plants et-cetra.
Some animals are unable to breed or produces organism due to genetic diosrders or mutaions, with the help of genetic engineering a DNA with gene of interest can be inserted in the host or animal cell, which will treat or remove the natural barries and will make enable it for breeding.
Hence, the correct answer is Genetic engineering.
How are the blunt and sharp pipettes
used in the cloning process?
(please answer in simple words i don't even understand the question)
Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

Explanation:
Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.
Answer:
Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.
Explanation:
The table and data was not attached to the question.
When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)
Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
That is mass of reactant = mass of product = 100g + 10g = 110g
Sarah got 105g as product because a gas of mass 5g was released during the reaction.
Sarah found the mass of the resulting
mixture without including the mass of the released gas.
A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.
When this is done, the law of conservation of mass would be proven.

Explanation:
Predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein instead of free in the
culture.
Answer:
Since the cell membrane is semi-permeable, the likelihood of substance L entering the cell attached to a large protein is lower than that of substance L free in the culture. Substance L enters the cell membrane through active transport, but the cell membrane may block the larger protein, thus blocking substance L, if it is attached to the large protein.

If you stand on the edge of a canyon and shout, you will hear an echo. That is,
some time after you shout, you will hear your shout again coming up from the
canyon. Describe what is happening to the sound of your shout to make this
happen.
Answer:
The soundwaves bounce off the canyon walls and back to you
Because sound waves bounce off surfaces and rebound, the shout will be reflected back to you. Often, music is captured in a space that is soundproof.
What is Sound wave?A sound wave is indeed the pattern of disruption brought on by the movement of energy moving through a medium because it propagates away from the origin of the sound (such as air, water, or any other kind of liquid or solid matter). Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.
A sound source, like a vibrating speaker's diaphragm in a stereo, produces the sound waves. Vibrations are produced in the medium surrounding the sound source. The medium continues to vibrate as the source does, and as they do, the vibrations move away from where they originated at the sound's velocity, resulting in the formation of the sound wave.
Thus, the shout will be reflected back to you since sound waves bounce off objects and rebound. Music is frequently recorded in a room that is soundproof.

What is complementary base pairing? Explain why complementary base pairing is necessary to maintain the double helix shape of the DNA molecule.
Answer:
A complimentary base pairing is how adenine can only bond with thymine and how guanine and cytosine through hydrogen bonding. It is necessary to maintain the double helix shape. Because it is opposite, that is why the DNA is that shape. It is anti parallel due to the Complementary base pairing.
Adenine can only bond with thymine and guanine with cytosine via hydrogen bonding. It's important to keep the double helix shape. Complementary base pairing causes antiparallelism.
Why complementary base pairing is necessary?Base pairs linked to a sugar-phosphate backbone form the double helix structure of DNA.
DNA is composed of four nitrogenous bases: thymine, adenine, guanine, and cytosine. Guanine and cytosine are linked by three hydrogen bonds, while adenine and thymine are linked by just two. The term for this is complimentary base pairing.
Complementary base pairing is critical for the formation of the helical helix of DNA because it permits the base pairs to be organized in the most energetically favorable manner. It is also essential for replication since it permits semiconservative replication.

The diagram below shows the Moon's orbit around Earth. Letters A, B, C, and D represent four positions in the Moon's orbit.
What is the approximate length of time it takes the Moon to travel from position A to position C?
1 day
14 days
28 days
31 days
Answer:
14 days is the correct answer. Since it takes 27(approx) days to complete one revolution of the earth and will take (27/2=14) days to complete half of the revolution I.e. A to C.
The orbit of the Moon around Earth is shown in the diagram below. Four locations in the Moon's orbit are represented by the letters A, B, C, and D.
How long does it typically take the Moon to move from position A to position C?
The Moon takes 28 days to go from location A to position C, which is a rough estimate. The Moon is at perigee, or its closest point to Earth, at position A. The Moon is at its apogee, or furthest point from Earth, at location C. Even though the Moon's orbital speed varies, it does take about 28 days to go from perigee to apogee. The Earth's orbit around the Sun and the Moon's orbit are both inclined.
This indicates a tilt between the orbital planes of the Earth and the Moon. The Moon's location with relation to the Sun consequently shifts throughout time. The Moon appears to "wax" and "wane" in the night sky because of this. The 28-day synodic period of the Moon accounts for the Moon's shifting positions with respect to the Sun.
Therefore, it may be concluded that it takes the Moon 28 days to roughly travel from place A to position C. This is due to the Moon's relatively slow orbital motion, which takes around 28 days to complete from perigee to apogee and from one place in relation to the Sun to another.

What would happen if a light source was placed below a plant?
• the plant would respond negative to gravity
• the plant would exhibit negative phototropism
• the plant would respond positively to gravity
A plant would respond positively to gravity if a light source was placed below a plant.
TROPISM:
Tropism is the movement of a plant or part of a plant in response to stimulus (light, heat, water). A plant's response to light is called phototropism while plants response to gravity is called geotropism. Ideally, a plant's shoot is positively phototropic while a plant's root is positively geotropic. Hence, if a light source is placed under a plant, the plant would respond positively to gravity.Learn more at: https://brainly.com/question/10942902?referrer=searchResults
