about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/

Proteins are chains of amino acids bonded together. Which is the correct sequence for making proteins?
Answer:
i wish i could help
Explanation:
iwe have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:

Describe the process of respiration which takes place in human beings whe
oxygen is not available and give an effect.
(T
Answer:
The process in which respiration takes place without oxygen is called as anaerobic respiration.
Aerobic respiration In anaerobic respiration the energy produced is very low as compared to aerobic respiration The organisms which use this type of respiration process are fungi, yeast In this process, (in yeast) glucose broke down into pyruvate and gives ethanol , carbon dioxide and energy In human muscle cells when there is a lack of oxygen this process occurs in which lactic acid and energy are produced.More to know -Pyruvate is three carbon -molecule.
The build up of lactic acid causes cramps in muscles.

All proteins found embedded in the cell membrane are transport proteins
Answer:
False!
Explanation:
False: All proteins embedded in the cell membrane are not transport proteins instead they are not just involved in transportation of molecules but also in other functions.
Cell membrane is the outer covering of most of the type of cells except in plants and bacteria where cell wall is the outermost layer.Cell membrane is made up of phospholipid bilayer. The proteins embedded in the cell membrane are not only the transport proteins but proteins that are responsible for cell to cell communication, responsible for maintaining shape of the cell, and those responsible for triggering chemical messengers all are present.Learn more about cell membrane:

what is the building block of nucleic acids
Answer:
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
I found this on google because I am not the best at explaining things but I hope this helps :)
The building blocks of nucleic acids are nucleotides, which consist of a sugar molecule, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
What are nucleotidesNucleotides are the building blocks of nucleic acids, such as DNA and RNA. They consist of a sugar, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
Nucleotides link together through phosphodiester bonds, forming the backbone of nucleic acid chains. The sequence of nitrogenous bases along the chain encodes genetic information. Adenine pairs with thymine or uracil in RNA, while guanine pairs with cytosine, creating complementary base pairs.
Nucleotides play a crucial role in storing and transmitting genetic instructions, serving as the foundation for DNA and RNA molecules.

When discussing Newton’s laws of motion, which terms do people most likely use when talking about Newton’s third law of motion?
A. “action” and “reaction”
B. “mass” and “inertia”
C. “inertia” and “force”
D. “force” and “acceleration”
Answer:
A. action and reaction
Explanation:
the third law is:-
Every Action has it's opposite and equal Reaction
Answer:
The correct answer is "action" and "reaction".
Explanation:
Newton's Third Law is: "for every action, there is an equal and opposite reaction". This means that every time something is pushed on, the other object pushes back. For example, when a swimmer pushes off the wall of a pool, the wall will push back on the swimmer, giving them the push they need to swim to the other side.
