The type of molecule represented below is found in organisms.
Which statement correctly describes the sequence of bases found in this type of molecule?
A) It changes every time it replicates
B) It determines the characteristics that will be inherited
C) It is exactly the same in all organisms
D) It directly controls the synthesis of starch within a cell
Answers
Answer:
B) It determines the characteristics that will be inherited
Explanation:
The molecule is DNA (it has a double helix structure) which contains genetic information needed for every living organism.
Hope this helps!
Answer:
D
Explanation:
A and C are so incorrect. The reason why D is the correct answer is because DNA does not determine what gets inherited, just what gets added to the gene pool.
DNA does however control the synthesis of proteins by acting as instructions. Then these instructions are read and carried out by RNA to finally complete the process.

When the color of the light changes, the number of light red kidney beans will also change Write a hypothesis about the effect of the red light on the population. Use the "if . . . then . . . because . . ." format, and be sure to answer the lesson question: "How does natural selection change the phenotypes within a population over time?"
Answers
Answer: If red light is shined on a population of red walking beans then they would not be as red as when started because they need light to survive and red light is present but they reflect it until they need it to survive.
Mutations that naturally occur can change phenotype and if it is beneficial to the species then it will be past on if it is no then it will die before passing it on.
Answer:
Explanation:
Natural Selection is defined as the evolutionary process in which organisms better suited to the environment tend to survive and reproduce.
If red light is shined on the population of red walking beans, then the population of light red kidney beans will increase because they will be camouflaged in the light and would not be able to see. The red light will make the beans invisible to other organisms and animals, which increase the population and survival rate of the beans.

6. Based on the food web above, hunting of sharks by humans has increased in international waters. How
will the increase in humans hunting sharks affect the rest of the food web? (5 pts)
Answers
Answer:
Short term: The fish (that sharks feed on) increase, the aquatic plants decrease
Long term: The fish (that sharks feed on) decrease, the aquatic plants increase
Explanation:
Short term: The fish increase because the sharks that used to feed on them decrease hence they get eaten less. The increased fish eat a lot of plants hence aquatic plants decrease.
Long term: The increased fish will then compete for the few aquatic plants present. Only the stronger fish survive hence most fish starve and die. Less fish means that the aquatic plants are being eaten less thus the aquatic plants increase.

Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of ocean warming on the range of lionfish and, therefore, on biodiversity?
Rising ocean temperatures have expanded the range of the lionfish; with little competition, it consumes smaller fish, reducing biodiversity.
Global warming has forced the lionfish to warmer waters where it is able to mate with native fish, increasing biodiversity.
Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Lionfish thrive in high carbon dioxide environments; they eat all of the native species in the area, reducing biodiversity.
Answers
Answer:
Rising ocean temperatures have expanded the range of the lionfish; with little competition, it consumes smaller fish, reducing biodiversity.
Explanation:
As ocean temperatures have increased, the range of the lionfish has increased. As a top predator, it has little competition for eating smaller fish, causing massive destruction by eating endangered fish, reducing biodiversity.

how does gel electrophoresis separate DNA? and how is genetic engineering used to treat genetic diseases??
Answers
Answer:
How does gel electrophoresis separate DNA? :
The technique of gel electrophoresis is used to separate DNA fragments based on their size. DNA samples are placed into wells (indentations) at one end of a gel and pulled through using an electric current. Negatively charged DNA pieces gravitate toward the positive electrode.
How is genetic engineering used to treat genetic diseases? :
Gene therapy aims to rectify genetic abnormalities and thereby prevent or treat hereditary disorders by modifying genes. Genetic engineering tries to tweak genes to improve an organism's capabilities beyond what is normal.

What is some information about Photosynthesis?
Answers
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll.
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals.Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.Photosynthesis starts when chlorophyll absorbs energy from sunlight. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.Photosynthesis is very important because almost all living things depend on plants for food. Photosynthesis is also important because of the oxygen it produces. Humans and other animals need to breathe in oxygen to survive.Some living things other than plants also make their own food through photosynthesis. They include certain types of bacteria and algae.
