Answer:
Change in DNA leads to change in the structure of the cell.
Explanation:
Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.
How does grain used for meat production and biofuel contribute to food insecurity?
Answer:
The effects of growing biofuel demand are interwoven with tightening grain markets, which reflect demographic shifts and improved diets. In developing countries, as populations grow and incomes rise, diet preferences are shifting from staple crops to higher-value products like meat and dairy
Explanation:
The grain that should be used for production of meat and the biofuel contribute to food insecurity should be explained below.
Contribution to food insecurity:The impact of growing the demand related to the biofuel should be considered as the interwoven along with the tightening grain market that represent the demographic shifts also the diet should be improved.

[25 pts] Why could a spinal injury leave someone paralyzed? Please provide an explanation! Thanks :)
Answer:
a spinal injury could include pressure on the spine and swelling that puts pressure on the spinal cord and nerves which can produce paralyizing problems. also a broken disk can put pressure and block the nerve endings which may be severed to promote conduction between the nerves causing paralyizing effects.
Explanation:
Answer: A spinal cord injury (SCI) causes damage to the spinal cord in its function. Injuries can result anywhere from a simple pain to complete loss of sensation. A spinal injury can leave someone paralyzed because it is known as the brains relay system. So, if the brain can’t relay its messages to the rest of the body it May be paralyzed. One example would be T4 on the right and T6 on the left side of your body with little to no function.

The greatest extent of membrane-bound compartmentalization occurs in Group of answer choices archeaa bacteria eukaryotes viruses
Answer:
The correct answer is - eukaryotes.
Explanation:
Eukaryotic organisms are the organisms that have membrane-bound organelles or compartments in their cells that play different types of roles in the cell such as assisting in cellular respiration, photosynthesis, packaging and modifying the proteins, and also helps in transporting them.
In archaea, bacteria and viruses lack true membrane-bound organelles in their cells and found very limited cell organelles like ribosomes and others but no membrane-bound organelles at extent of eukaryotic cells.
Elisa feels tired because she has a condition that affects whether the right molecules are getting to her cells. If her body were functioning correctly, this is what would happen with oxygen
Answer:
The oxygen is available in a right amount.
Explanation:
The oxygen is available in a right amount because her body were functioning correctly and we know that our body functioning correctly if it gets oxygen in a right amount otherwise body will not perform correctly its functions. The tiredness Elisa feels is due to her routine work which can be eliminated by doing rest for sometime so after resting sometime she feel better and active.
Elsie has the right amount of oxygen needed by the cells if her body were
functioning correctly.
Oxygen is an important in the body's metabolic processes and help in the
metabolism of glucose to energy which is needed by all the cells of the
body. When the oxygen is deficient , the blood won't be able to pump
oxygen through the blood to body cells.
This then results in decreased cell functions and metabolism thereby causing tiredness , cell damage and death if severe.

Two negatively charged objects exert a force on each other. Describe the force between the objects, and describe two ways to increase the force between them.
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Repulsion between chargesForce of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another.
Effect of distance on forceIf we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.

• Two leak-proof bags were set up. • One bag was made from artificial partially permeable membrane (Visking tubing). • The other bag was made from a piece of small intestine containing living cells, with its inner surface inside the bag. • The bags were filled with equal volumes of a dilute glucose solution. • The bags were suspended in the same glucose solution for two hours. • After two hours, the volumes of the bags were measured and the contents were tested for the concentration of glucose. Inside the bag made from small intestine the volume and concentration of the glucose solution decreased. There were no changes to the volume and concentration in the Visking tubing bag. (c) State and explain the process responsible for the decrease in the glucose concentration in the bag made from small intestine.
Answer:
The process by which the concentration of the glucose in the bag made from small intestine decreased is aerobic respiration.
Aerobic respiration is the process by which cells breaks down glucose in the process of oxygen to release energy for their metabolic needs.
Explanation:
Living things respire, that is they break down nutrients to produce energy for metabolic activities.
The bag made from visking tubing is made of non-living materials which do not respire. Therefore, the glucose concentration in it remains constant. However, for the bag made of small intestine containing living cells, the living cells will carry out aerobic respiration using the glucose molecules found in the glucose solution. During this process, glucose is broken down in the presence of oxygen to release energy for the cells. Therefore, the glucose concentration in the bag will decrease.

Which action would most likely increase the greenhouse effect?
A. Encourage people to conserve power
B. Use more nuclear power plants
C. Stop cutting trees in the Amazon forest
D. Burn more oil for heating homes
Answer:
D. Burn more oil for heating homes
Explanation:
Encouraging people to conserve power would help weaken the greenhouse effect, not increase it. Stopping cutting down the trees in the Amazon forest would also heavily help weaken the greenhouse and not increase it. And unlike the others, using more nuclear power plants wont affect the greenhouse atfect but instead affect our air quality. Our problem is that burning coal, oil, and gas produces carbon dioxide, which adds to the supply already in the atmosphere, increasing the greenhouse effect and thereby increasing the temperature of the Earth so therefore its D.
BURN MORE OIL FOR HEATING HOMES

Answer:20
Explanation:
its 20
Answer: The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.
What are recombinant types?
The heterozygous dominant species, in this case, is YyLl, where Y stands for the dominant trait over y and T stands for the dominant trait over t.
Recombinant species will exhibit features that are heterozygously expressed in both the dominant and recessive forms), and these traits are Yyll: 100 and yyLl: 100.
Therefore, The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.
