How do you explain that the variability in a domesticated species is greater than in the same species, or a similar one, in the wild? For example: dogs vs. wolves; chickens vs. red jungle fowl.
Explanation:
i believe it is because the domesticated breeds were bred specifically through generations in order to serve a specific purpose, for example dogs could be bred for hunting or herding, etc and chickens could be bred for eggs or meat, etc. but in the wild, their only job is to survive and reproduce.
Imagine you are a member of a scientific committee that is working on writing a set of ethical standards for cloning research. What are some of the most important concerns you would want to have covered by those standards?
If you were a beef producer, how would you view the cloning of cattle that is now possible? List any resources you used to answer this question.
Answer:
Here are some points you could use
1) Safety of the original clone
2) Any chemicals used that could result in defects in the clone or original
3) Will clone contain chemicals that can affect the consumer of beef
4) Will clones be able to reproduce with other clones or non-clones and will that result in birth defects?
5) Exlusive technology not to be available to the public, only for research
6) Can this tech be used to clone humans for organs

Could two humans have some differences caused by mutation in their DNA sequences for insulin, yet still make the exact same insulin proteins? Question 7 options: No, DNA is very precise and only one specific sequence will produce insulin No, each person's DNA is unique and will make a unique insulin protein Yes, different codons can code for the same amino acid.
Answer: Yes
Explanation:
Two humans have some differences caused by mutations in their DNA sequences for insulin, yet they still make the exact same insulin proteins, and this is true. The correct answer is yes; different codons can code for the same amino acid, which is the last option.
What are DNA and genetic code?The genetic code is the set of rules by which the nucleotide sequence of a DNA molecule is translated into the amino acid sequence of a protein. A codon is a sequence of three nucleotides that specifies a particular amino acid. There are 64 possible codons but only 20 amino acids, so the genetic code is degenerate or redundant. This means that different codons can code for the same amino acid.
Hence, two humans have some differences caused by mutations in their DNA sequences for insulin, yet they still make the exact same insulin proteins, and this is true. The correct answer is yes; different codons can code for the same amino acid, which is the last option.

Consumers eat producers and decomposers get nutrients from both when they die.
What do you mean by consumers?A food chain consumer is an organism that eats organisms from different populations. The consumer is a heterotroph and the producer is an autotroph.
Organisms that eat producers are primary consumers. They are usually small and numerous. The main consumers are herbivores (vegetarians).
Consumers play an important role in the ecosystem by regulating the population growth of organisms and supplying energy to other organisms. Removing any species, producer or consumer from an ecosystem can destabilize the ecosystem.

What’s air, water, and soils role in the carbon cycle
Answer:
They are reservoirs of carbon in the carbon cycle.
Explanation:
A biogeochemical or nutrient cycle has two major components:
the reservoirs of the biogeochemical or nutrient, andthe processes involved in cycling the biogeochemical or nutrient between the reservoirs.Air is a reservoir of largely inorganic carbon (as carbon dioxide) while water and soils are reservoirs of both organic (e.g. dead decomposing organisms and hydrocarbons) and inorganic forms of carbon (e.g. carbon-containing minerals such as limestone, calcium carbonate).

There are estimated to be over 50,000 different species.
C.
Protozoans can be heterotrophic or autotrophic.
D.
Protozoans can be unicellular or multicellular.
Answer:
pretty sure that its c
Explanation:
Answer:
B
Explanation:
Answer B is correct:
Because the biologists are continuing to learn more and more about
such minute organisms, protozoan systematics – that is, the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a topic of debate and change, still today.
Some of the rather LARGE and unwieldy taxonomic groupings of past years are particularly subject to revision with expansion of and refinement in the knowledge about the members of those – and related – assemblages. Paradoxically, the protozoa themselves are becoming more difficult to define with precision as our information about them and other microbial assemblages increases. Thus, presenting a single satisfactory circumscribed definition for them is not an easy task.
...
Answer A sounds so funny.
Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

Explanation:
List 5 changes that could be made in your community that could
help protect the environment.
Answer:
-distribute energy grids
-recyling manufacturers for recycling resources that are not just plastic
-composting food waste to produce nutrient dense soil for crops
-conserving water= using it only when its needed
-walking biking or taking public transport instead of a car to reduce pollution and traffic amongst the streets
1) Reduce, reuse, and recycle. Cut down on what you throw away. Follow the three "R's" to conserve natural resources and landfill space.
2) Volunteer. Volunteer for cleanups in your community. You can get involved in protecting your watershed, too.
3) Educate. When you further your own education, you can help others understand the importance and value of our natural resources.
4) Conserve water. The less water you use, the less runoff and wastewater that eventually end up in the ocean.
5)Use long-lasting light bulbs. Energy efficient light bulbs reduce greenhouse gas emissions. Also flip the light switch off when you leave the room!
How has human activity impacted the evolution of the peppered moth?
Answer:
Most peppered moths used to be grey with dark spots, but have evolved to be mostly black. This is because pollution from the Industrial Revolution threw soot on the trees causing them to look black. This gave the black moths camouflage from predatory birds meaning they survived and reproduced. By survival of the fittest, the peppered moths became black like the trees.

In 2007, New York City attempted to install a commercial wave farm
underneath the East River. Why did it fail?
Answer:
Because of the fact that it was very Deep and heavily polluted.
Explanation:
Actual main channel depths along the river vary; with a least depth of 24' or less at a few locations at the channel edges to a maximum depth of 108' being found mid-channel at the southern approach to Hell Gate.
Due to heavy pollution, the East River is dangerous to people who fall in or attempt to swim in it, although as of mid-2007 the water was cleaner than it had been in decades.

How can radio-frequency produce heat?
Answer:
Radio frequency is short for RF, which is a kind of high frequency alternating current electromagnetic wave with frequency range from 3k hz-3k GHz
Because the frequency is high, so the molecular movement speed is fast, and the physical explanation of the heat of the object 100 is its internal molecular movement speed, the use of radio frequency energy to make the molecular high speed movement of course will achieve the purpose of heating
Answer:
Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. It is a type of non-ionizing radiation. ... If RF radiation is absorbed in large enough amounts by materials containing water, such as food, fluids, and body tissues, it can produce heat.
