C.
Lisa might lose her friends because she is devoting too much time to working out.
D.
Lisa might experience symptoms of overtraining, like weight loss and increased irritability.
Answer:
D). Lisa might experience symptoms of overtraining, like weight loss and increased irritability.
Explanation:
The biggest concern after continuing the program for a few months would be that 'Lisa might experience the symptoms associated with overtraining including weight loss and enhanced irritability.' These are the initial symptoms which shows the strain that is being put on the muscles of the body. It may also cause her to face muscle pain, fatigue, a decline in appetite. Gradually, her body would adapt to the schedule and show the desired results. Thus, option D is the correct answer.

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.

The second option: meiosis and fertilization
process A is meiosis, you can see that the gamete(haploid cell) results from the diploid cell. The gamete has n chromosomes(39), whereas the diploid cell has 2n(78)
process B is fertilization the two gametes(haploid) fuse together to form the zygote(diploid)
Explanation:
Process A allows the chromosome number in the dog cells to be reduced by half. This is only possible due to meiosis as it undergoes 2 phases of meiosis/cell division which is meiosis I and II. (From 2n to 4n to 2n to n)
(After mitosis, the chromosome number will remain constant even though DNA replication occured in S phase, as there is only 1 phase of mitosis/cell division, so from 2n to 4n back to 2n)
Process B allows the dog gamete cells to undergo fertilization and produce a zygote, therefore the chromosome number returns back to 2n.
(Pollination only occurs in plants, not in animals such as dogs and humans)
The correct answer is Meiosis and Fertilization.
A nonnative species of fish is introduced into a lake. Which would most likely prevent this fish from becoming a invasive species?
Answer:
B
Explanation:
A- The lake ecosystem has no other larger fish
B- The fish shares a niche with another species
C- There are no organisms that would eat this fish
D- The fish can thrive in the temperature of the week
The correct answer would be option B.
One of the factors that promote invasiveness in exotic species is if such species lack natural predators or competitors. In other words, the invasiveness of a nonnative species can be promoted when they occupy a previously unoccupied niche, resulting in a lack of competition. The presence of a competitor will either results in a competitive exclusion that might not favor the newly introduced species or resource partitioning that sort of limits their growth.
Hence, in the case of the nonnative fish introduced into a lake, sharing a niche with another species can prevent it from becoming an invasive species.
Answer:
B. The fish shares a niche with another species.

Explanation:
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.
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:

How does pressure change as you move from earths surface to inner core?
Answer:
The outer core lies under the mantle, and is 1,400 miles thick. Temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above
Explanation:
Answer:
The inner core at the center of the Earth consists mostly of iron. This layer is less than 800 miles thick. Even though the inner-core temperature is now thought to be hotter than the Sun's surface, the tremendous pressure this deep inside the Earth overrides the effects of temperature and prevents the iron from being liquefied. Instead, the iron at the core is a solid and has a spherical shape. also the other person looked this up on the internet

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
