what describes skeletal muscles
"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."

If I have 14 guanine and 37 thymine, how many adenine will I have?
If I have 14 guanine and 37 thymine, then 37 adenine bases will be present in the individual.
What is base pairing?Base pairing is the process by which nitrogenous bases in DNA molecules bind to each other through hydrogen bonds to form the characteristic double-stranded structure of DNA.
Adenine (A) is always associated with thymine (T), and cytosine (C) is always associated with guanine (G).
As a result, knowing the number of guanine and thymine bases in a DNA sequence allows us to calculate the number of adenine and cytosine bases.
We know there are 37 adenine bases because adenine always pairs with thymine and you have 14 guanine bases and 37 thymine bases.
This is because the number of A bases in a double-stranded DNA molecule will always equal the number of T bases, and the number of G bases will always equal the number of C bases.
Thus, there will be 37 adenines.

If Nation A needs a natural resource that Nation B has a lot of why might Nation A have trouble getting that resource from Nation B?
Answer:
1. Thermostat.
2. Work out of.
3. Non-renewable.
4. Renewable resources.
5. Conservativism.
6. Non-renewable resources.
7. The reason Nation A might have trouble getting that resource from Nation B could be due to lack of funds (insufficient money) to acquire it, competition for the same resource by other nations, weak bargaining power of Nation A, ability to pay more money by other nations, Nation A and Nation B might be in conflict, tariffs and quotas, etc.
Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
On the other hand, a non-renewable energy refers to an energy source such as fossil fuels that takes a very long time to be created or their creation happened long ago and isn't likely to happen again e.g uranium. Fossil fuels, such as coal, oil, and natural gas, come from deep inside the Earth where they formed over millions of years ago.
Filling the missing words or texts into questions, we have;
1. Set thermostat to automatically turn off heat or air conditioning when buildings are closed to conserve energy.

g Both transduction and transformation establish that DNA is the genetic material of most living organisms. Both processes involve transfer and expression of DNA from cell to cell. What then is the difference between the two processes: Question 27 options: transduction is mediated by a phage while transformation requires a plasmid Both processes are mediated by a virus transformation is accomplished by a virus, and transduction is carried out by a bacterium transformation is carried out by random uptake of DNA, and transduction by a bacterial virus none of the choices are correct
Answer:
transformation is carried out by random uptake of DNA, and transduction by a bacterial virus
Explanation:
Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.
However, both processes are different in the way they get the foreign DNA into the bacteria cell.
- Transformation involves the random uptake of foreign extracellular DNA by the host bacterial cell.
- Transduction involves the transfer of foreign DNA into a bacteria cell via a virus called BACTERIOPHAGE. N.B: A bacteriophage is a virus that infects a bacteria host.

There are almost 10,000 known bird species on the planet. How did they evolve into so many unique forms?
Answer:
Natural selection.
Explanation:
Imagine in the beginning there was a single species of bird. Naturally, this bird had to expand to the rest of the world, and was distanced as the continents drifted off. But this bird had to cope with various climates and environments. So the bird would gradually mutate over time. The bird in the jungles of central america would develop different colors and a shaped beak, and would better help it survive. This led to being the new normal for birds of this area. It would evolve to cover all the surviving birds in the region, until it is so drastically changed then it is a new species. There are so many different environments, each with its own challenges to overcome, so so many different bird evolve to survive them.

Ms. AB was traveling and caught a nasty flu on the plane. But because she had work and school she could not take any
time off to rest during her flu. 2 weeks after she contracted the flu, she no longer had the fever and sore throat, but her
nose was still stuffy, and she was suffering from sinus headaches. She went to her doctor, who diagnosed her with a
sinus infection and prescribed her a course of antibiotics. Ms. ABC took the 7 days of antibiotic therapy, but she is now
back at her doctor's office with a yeast infection and diarrhea. Explain, why Ms. ABC developed the sinus infection. Then
explain why she developed a yeast infection and diarrhea after the course of antibiotics
Answer:
Antibiotics killed the bacteria that cause infection but they can also kill beneficial bacteria . thus Ms ABC developed a yeast infection and diarrhea after course of antibiotics because antibiotics distrub natural balance of beneficial bacteria in her intestine.
Ms. ABC developed a yeast infection and diarrhea after the course of antibiotics because the exposure to antibiotics may kill beneficial bacteria which prevent other diseases to occurs in the body.
What is an Antibiotic?Antibiotics may be defined as a type of medicine that significantly inhibit the growth of microorganisms especially bacteria inside the body of living organisms. Such type of antimicrobial substance may either kill or inhibit the growth of bacteria.
It is the most prevalent kind of antibacterial agent for conflicting bacterial infections, and antibiotic medications are tremendously utilized in the treatment and prevention of such infections.
With the effect of antibiotics, beneficial bacterial species that are living in the intestine may also be killed. Due to this, Ms. ABC becomes susceptible to other types of infections like yeast and diarrhea.
Therefore, exposure to antibiotics may significantly kill beneficial bacteria which prevent other diseases to occurs in the body.

identify two other physical factors and explain their effect on the organism living in the lake?
Answer:
The correct answer is - light level and temperature.
Explanation:
The structure and function of lakes are determined by various factors such as temperature, light level, wind turbulence, water flow rate, dissolved oxygen, acidity (pH), salinity, habitat size, hydrology, and water depth. Stratification and water circulations are influenced by temperature and wind turbulence.
Light level is an important abiotic factor in lake ecosystems. Light is an essential part for plants to perform photosynthesis. Light can directly affect how much life you find in a given area depends on the production of energy and food by the aquatic plants by photosynthesis.
Temperature is a similarly important factor for lakes or other aquatic organisms as it is for land animals. each organism is able to survive in specific temperature ranges and their metabolic activity also depends on the specific temperature range.
