Flower color in the garden pea is due to two interacting genes, A and B. If either gene is recessive (aaB_, A_bb, or aabb) then the phenotype is white. A dominant allele must be present at both genes for flower color to be purple. After a testcross of an individual with a genotype of AaBb, what proportion of the progeny will have purple flowers
Answer:
4/16 = 1/4 = 25% of the progeny is expected to be purple (AaBb)

what ia arumen in ruminant animals
Answer:
Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre
The rumen. The rumen (on the left side of the animal) is the largest stomach compartment and consists of several sacs. It can hold 25 gallons or more of material depending on the size of the cow. Because of its size, the rumen acts as a storage or holding vat for feed.

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.

what is the role of bacteria in moving nitrogen through the ecosystem
Answer:
The most important part of the cycle is bacteria. Bacteria help the nitrogen change between states so it can be used. When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
Answer:
Hope this helps....
Explanation:
Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.

The diagram below shows a stack of rock layers. These layers have not changed position since they formed. Examine the diagram and answer the question that follows. If the age of Layer 4 is 400 million years and the age of Layer 1 is 500 million years, then the age of Layer 3 is A. older than 500 million years. B. between 400 million and 500 million years. C. 500 million years. D. younger than 400 million years.
The age of layer 3 will be between 400 million and 500 million years. Therefore, option (B) is correct.
Why rock dating is important?Finding estimates of the ages of rocks is essential for identifying the speeds of geological processes as well as the history of geological occurrences. Some rocks may be used to determine the relative sequence of events. The most well-known methods are uranium-lead dating, potassium-argon dating, and radiocarbon dating.
Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may use tools like these to assess the age of a material since radioactive isotopes degrade over a predictable period of time. mass spectrometer for thermal ionisation

Answer: A, E
Explanation: I took the USA Test Prep and the person above me who commented said so.
An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.

Answer:
The answer is A,B and C
Explanation:
The correct options are A, B and D. The frequency of an allele in a population is referred to as its allele frequency.
What is allele frequency?It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population.
Additionally, it is feasible to determine genotype frequencies (the percentage of people who share a particular genotype) and phenotype frequencies (the percentage of people who share a particular phenotype).
Different from genotype or phenotypic frequency is allele frequency. Calculating genotype and phenotypic frequencies is also useful for studying how populations change, although they are not the same as allele frequency.
