The nucleus uses the nucleotide sequence of DNA as a template to make mRNA. The enzyme RNA polymerase II catalyzes this activity, which requires nucleotide triphosphates as substrates. Transcription is the process of producing mRNA from DNA, and it takes place in the nucleus. The DNA of a gene serves as a template for complementary base-pairing during transcription, and an enzyme known as RNA polymerase II catalyzes the synthesis of a pre-mRNA molecule, which is then processed to generate mature mRNA.

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?"
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.

A type of genetic inheritance in which two phenotypes are seen together on the offspring is known as:.
Answer:
Codominance
Reason:
A codominance connection exists between two copies of a gene. Individuals inherit one copy of a gene, known as alleles, of each parent. If they are different , the allele that is dominant will typically be displayed, while the influence of the other allele, the recessive, will be concealed.
Answer:
Codominance
A codominance connection exists between two copies of a gene. Individuals inherit one copy of a gene, known as alleles, of each parent. If they are different , the allele that is dominant will typically be displayed, while the influence of the other allele, the recessive, will be concealed.

What is some information about Photosynthesis?
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.

An animal can wound a tree by scratching away the bark.. The tree can respond to the wounded many ways. Usually sapped quickly covers the wound, and then the tree covers the wound with new growth.
The diagram below shows a cross-section of the tree with a healed wound. What process works most directly with the transport system to heal the wound.
a. cellular reproduction
b. photosynthesis

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)
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.

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

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.

Which of the following might occur if people fail to conserve water? a. Increased sewage system failures b. Increased numbers of natural pollution filters c. Increased water supply d. Increased wildlife habitats.
Answer:a
Explanation:edge 2022
If people fail to conserve water then there will be increased sewage system failures.
Water conservation entails keeping water from assets like rain, wastewater, and snow melting using it for family and agricultural activities. Increased sewage gadget disasters can not preserve water as this water comes from toilets, sinks, bathing, laundry, etc. That is wastewater and contaminants ought to be eliminated from it to make it appropriate for reuse. Failure of sewage gadget will now no longer be capable of taking away pollution from this water and therefore this can not be reused.What is a water sewage system?
These are 3 types of water sewage systems: separate system combined system partially separate system.
Hence concluded that if people fail to conserve water then there will be Increased sewage system failures.
