Explain the two reasons why DNA changes
Answer:
1.) Mutation or outside effect
2.) The DNA copies itself
Explanation:
1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.
2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”
hope this helped!

What kind of geographic barriers would have led to the finch in the Galapagos?
Answer:
Speciation in Galapagos finches occurred by founding of a new population, geographic isolation, changes in the new population's gene pool, behavioral isolation and ecological competition.
Explanation:
Geographical limitations include the natural factors or the water bodies like ocean, sea, rivers etc. that divide a place from another is called geographical barrier.
Galapagos finches are recognised as Darwin finches because he discovered them on the Galapagos island.
There is an unusual difference in their beak structure and purposes even though they reside on the same island.Speciation in finches transpired due to geographic separation, the modification in the population gene, ecological conflicts.When the species of finches were restricted to a specific area and could not mate resulted in isolation and hence variation.To learn more about Speciation and Darwin Finches follow the link:

What is the percent by volume of a solution formed by adding 15 L of acetone to 28 L of water?
Answer:
34.88 %
Explanation:
To solve this question, we are going to assume that the acetone has 100% solution.
We know that 15 L of acetone was added to 28 L of water
We need to determine the percent by volume of a solution as
15 L of acetone/ (15L of acetone +28L of water)
= 15L/43L
=0.3488
= (0.3488×100%)
= 34.88 %
Hence, the percent by volume of a solution formed is 34.88
1. Baking soda turns.............
1.turmeric red
2.purple cabbage juice green
3.red litmus blue
4.all of the above
Answer:
D) all of the above
Explanation:
Turmeric, purple cabbage juice (containing anthocyanin), and litmus paper all act as indicators which help us to detect whether a particular substance is acidic or basic.
In basic medium, turmeric changes it's colour to red, purple-cabbage juice turns to green and red litmus turns to blue.
Baking soda/Sodium carbonate Na
is basic in nature and thus causes the above changes in the indicators.

What is the function of Nucleic Acids?
Answer:
he functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Explanation:
Answer:
Genetic information. The main job of the DNA is to carry the code for making proteins. A gene is a stretch of DNA that can be be read by proteins called ribosomes and copied into a type of nucleic acid called messenger RNA.
The 3 main functions of nucleic acid
1.) is to store and transfer genetic information.
2.) the deoxyribonueic acid is the storage for place for genetic information in the cell.
3.) DNA controls the synthesis of RNA in the cell.

according to the Minnesota Pollution Control agency water quality is usually exceptional high in the Northeast part of the state intends to degrade as you go to the South and Southwest some 40% of the lakes and streams are polluted with much of that censored in southern Minnesota in 6 far Southwestern Minnesota counties there are no lakes considered fishable and swimmable what is the most likely source of water pollution in the southern parts of Minnesota?
A. agriculture
B. mercury in rain
C. Thermal Pollution
D. factories and industry
Answer: Option A Agriculture
Explanation: As we move towards the South and southwest some 40% of the lakes and streams are polluted this is because of the agricultural run off. The fertilizers and other pesticides leach from the soil into the water bodies which can pollute water to a great extent.
The fertilizers contains many elements which is good for plants when they leach into the water bodies they are harmful for aquatic life.
Example: Presence of mercury in fertilizers can harm the aquatic life and acts as toxins above the permissible limit.
This is the main reason the water their is very polluted and is not fishable and swimmable.

Infants will often smile when they hear a parent’s voice. In this situation, the parent’s voice is considered
A: a stimulus
B: a response
C: an adaptation
D: a resource
Answer: C: An adaptation
Explanation:
Answer:
The correct answer is- a stimulus
Explanation:
The bonding and early life attachment between the infant and caregiver is a dynamic, bidirectional process that includes both caregiver nurture and complementary infant behavior that elicits parental caring. Attachment appears to have two purposes. The primary role is to keep the infant near to the caregiver so that it can receive the care it needs to survive.Animal studies have discovered that both loving and unpleasant cues linked with the caregiver promote attachment. Second, the quality of connection and the sensory cues that accompany it arrange the brain to define the cognitive and emotional development of the newborn. The infant's brain function and behavioural expression are regulated by the patterning and quality of care, which impacts long-term emotional control.More examples about Stimulus found in https://brainly.com/question/26306069?referrer=searchResults
