_____ cannot be grown in a lab culture unless living cells are present.
A. Fungi
B. Plants
C. Viruses
D. Bacteria
Answer:
B. Viruses
Explanation:
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Nitrogen bases pair with bases that are...

complementary
complementary and identical
identical
Nitrogenous bases basically pairs with bases that are complementary. The correct option is B.
What are nitrogenous bases?Nucleobases, also referred to as nitrogenous bases or purely bases, are nitrogen-containing biological molecules that form nucleosides, which are then constituents of nucleotides, all of which are the basic building boxes of nucleic acids.
A set of 5 nitrogenous bases is used to build nucleotides, which then in results nucleic acids such as DNA and RNA.
These bases are critical because their sequencing in DNA and RNA is how information is stored.
A base pair in DNA are complementary to each other. Under normal conditions, the nitrogen-containing bases adenine (A) and thymine (T) pair, whilst also cytosine (C) and guanine (G) pair.
The structure of DNA is formed by the binding of these base pairs.
Thus, the correct option is B.

Researchers are not making any progress in treating or curing AIDS. Please select the best answer from the choices provided T F
Answer:
True.
Explanation:
Researchers and scientists are not making any progress in treating or curing AIDS because the virus incorporates itself into the host cell's DNA and the medication is unable to reach that place so the virus is safe from the medication and remains in the host cells. This diseases can't be cure but can be prevented of spreading further in the body through medication such as antiretroviral therapy (ART).

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra preta? How is bio-char different from the traditional Amazonian method of creating terra preta?
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.
What is terra preta soil?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.

Which of the following is not an example of mutualism?
Plsss help
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!

Which process has evolved to yield the GREATEST variation of offspring?
A.Meiosis
B.Mitosis
C.Replication
Meiosis has evolved to produce the greatest variation of offspring.
What is meiosis?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.

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