Answer:

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.

During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.

In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.

Frameshift mutation

Explanation:

A frameshift mutation is a genetic mutation caused by insertions or deletions that shift the whole sequence.

Answer:

D. Conifers and Grasses spreading their pollen with the wind.

Explanation:

Let's start with what mutualism is. Mutualism is when both parties of a relationship benefits. So, when you go to the doctor, this would be mutualism. The doctor is getting paid, and you are getting healthy. Both sides benefit!

Now let's go thrugh out examples.

Moths drinking nectar and pollinating night blossoming flowers: The moths get fed (nectar), and the plants get pollinated (their whole purpose). Both sides benefit.

Bees drinking nectar and pollinating many angiosperms of food supply: This option might seem confusing because of the term angiosperm. I promise it isn't! Ignore angiosperm. Bees are drinking nectar -> they benefit. The other thing is getting pollinated. All plants like getting pollinated, no matter their fancy name. So both sides benefit!

Beekeepers maintaining colonies of bees and moving them to different farms and orchards: This one might also have been hard, because it requires sme critical thinking. Let's look at the beekeepers first. Beekeepers make money off of honey when they have bees, so they benefit. But do bees benefit in this relationship? Yes! Bees like having lots of plants to pick from to get their pollen. By being moved to an area with lots of plants, they get more pollen, so they benefit!

Now, we know the last one HAS to be right. But let's go through it anyways.

Conifers and Grasses spreading their pollen with the wind: Right away we know the conifers and grasses are benefitting. They want to spread their pollen- why else would they do it? But, to be mutualism, another party has to be benefitting. In this equation, there is no other party. Maybe you thought the win, or maybe you thought of the fields. What are they getting out of this relationship? Nothing. This is not mutualism.

Hope this helps and feel free to ask for any more clarification!

Answer:

When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.

Explanation:

Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.

Explanation:

All living organisms are built up with carbon molecules

The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence  of bases (genetic information) on DNA that codes for a protein is called a gene

Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.

It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.

the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.

In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.

Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

Answer:

What did researchers learn from terra preta?...  Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.

How is bio-char different from the traditional Amazonian method of creating terra preta?  Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..  

The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.

Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.

Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

Meiosis has evolved to produce the greatest variation of offspring.

Meiosis is a type of cell division that occurs in eukaryotic cells, such as those in animals and plants, to produce reproductive cells (gametes) that have half the number of chromosomes as the parent cell.

During meiosis, chromosomes pair up and  genetic material through a process called crossing over, creating genetic diversity among the gametes. This diversity increases the chances that at least one offspring will be better suited to its environment and increase the survival chances of the species.
