Answer:
It receives less direct sunlight than any other biome on earth.
Explanation:
The tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions.
The Tundra biome is a frozen landscape that has a dark and cold environment. It receives less sunlight compared to other biomes. Thus, option a is correct.
What are the characteristics of the Tundra biome?The Tundra biome is the biogeographical region that has the coldest atmosphere of all the other biomes and is marked by little precipitation, low temperatures, long winters, and short seasons for agricultural growth.
They are present in the Arctic circle as the temperature reaches below zero degrees celsius which can last up to ten months. It is mostly barren land and is majorly covered with willow trees, and birch trees. They receive very less amount of sunlight as they have a long winter season.
Therefore, Tundra receives less sunlight.

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.

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.

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.
2. Energy can be used more efficiently getting more work out of each unit of energy.
3. Materials, such as gravel and sand, are technically non-renewable but there is so much of the available that we are unlikely to ever run out.
4. Renewable resources can be regenerated or grow so rapidly that they reappear at the same rate or faster than they are used.
5. When we practice conservatism we make sure resources will be available in the future.
6. Non-renewable resources are resources that cannot be regenerated on a useful timescale.
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.

Cystic fibrosis is an autosomal recessive disorder where a chloride ion membrane channel protein doesn't function properly. People with cystic fibrosis suffer from chronic lung infections that make breathing very difficult. They also suffer from other issues such as an inability to produce enough digestive enzymes due to problems with pancreas cells. Suppose that Chris and Shannon are both carrier of cystic fibrosis (carriers have the allele but do not exhibit the disorder). What is Chris' genotype for the cystic fibrosis gene
Answer: Typically, the genotype in those patients consists of at least one very mild mutation uncharacteristic for CF patients. These are predominantly missense or splice variants, belonging to classes IV or V producing variable amounts of functional CFTR protein at the apical membrane.
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.

Today, you have learned some basic general information about bacteria that cause infections and bacteria that protect
and benefit us, living inside and on the surface of our bodies. So, here is a question for you to apply the knowledge you
gained today:
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.

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."
