what is mimicry in biology
Answer:
mimicry, in biology, phenomenon characterized by the superficial resemblance of two or more organisms that are not closely related taxonomically. This resemblance confers an advantage—such as protection from predation—upon one or both organisms by which the organisms deceive the animate agent of natural selection.

Which of the following statements about plants is not true?
a. They make their food from carbon dioxide and water through photosynthesis.
b. Land plants have cell walls that help hold their stems upright.
c. They have adaptations that help prevent water loss.
d. Plants absorb food through their roots.
Answer:
A
Explanation:
because plants use atmospheric carbon dioxide and water absorbed from the earth to create organic matter in the process of photosynthesis. On that occasion, oxygen is released.
Answer:
A
Explanation:
I hope this is correct, since every other version I've seen of this question option A is water and oxygen.
What are c3, c4, and cam plants?.
evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.
Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.
Bacterial cells are vastly different from human or animal cells. Some of these differences include:
Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagellaand many others.
Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.
Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

what is the importance of predation in an ecosystem
Answer:
Without predatation, things wouldn't eat each other.
Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...
If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)
It's a food chain. A CHAIN. Each varible depends on each other.
And a food chain has a direct impact on the ecosystem.
For example:
No rabbits mean there is so many grass and carrots left behind
No wolves means there are too many rabbits
So that means
No wolves
Whatever eats the wolves wont be alive
Whatever eats THAT wouldn't be alive

epigenetics
DNA replication
Methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.
What is the importance of methylation in the cell?Methylation has many functions, such as in gene expression, where it can turn genes on or off by altering the way that DNA is packaged, such as by tightening or loosening the gene so that enzymes can access it; in DNA stability, methylation can help protect the genome from damage by stabilizing the DNA structure; and in epigenetic regulation, where it plays an important role.
Hence, methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.

Answer:
Break down lignin.
Explanation:
The continual slow degradation of the phenolic portions of lignin (humic acids) provides a long-term supply of nutrients to plants. Phytoplankton (the primary producers in aquatic systems) do not synthesize appreciable amounts of lignin, and so fungi are not necessary to decompose it!
