Answer:
A
Explanation:
Natural selection occurs because those with more favorable traits survive while the others don't. If there are no favorable traits in a community then there is no natural selection.
Explain how and why weasels' coat color changes seasonally.
Answer:
Animals that live in areas that usually have a lot of snow in the winter often change their coats to match their surroundings. Some weasels have evolved so that in the autumn they moult their brown summer coat and change to a white version. In spring they reverse the process and return to the brown version

what makes organisms similar and different?
Answer:
One type of evidence for evolution (evidence that organisms are related, descended from a few common ancestors, and change to adapt to their environments) is that organisms are similar to each other, but not exactly the same. Similar organisms have differences that help them adapt to their environments.

How would a bacteria explore a non-coding portion of DNA?
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres. Its RNA counterpart is non-coding RNA.
The amount of non-coding DNA varies greatly among species. Often, only a small percentage of the genome is responsible for coding proteins, but an increasing percentage is being shown to have regulatory functions. When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. Since that time, this non-functional portion has controversially been called "junk DNA".[1]
The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity, which they defined as being transcribed, a definition not shared with most other biologists.[2] Though this was not necessarily unexpected due to previous decades of research discovering many functional non-coding regions,[3][4] some scientists criticized the conclusion for conflating biochemical activity with biological function.[5][6][7][8][9] Estimates for the biologically functional fraction of the human genome based on comparative genomics range between 8 and 15%.[10][11][12] However, others have argued against relying solely on estimates from comparative genomics due to its limited scope.[citation needed] Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions and is being explored in evolutionary developmental biology.[4][11][13][14]

The monarch butterfly stores a poisonous chemical from the milkweed plant in its body. The chemical makes the other animals who might eat the monarch butterfly sick. This is an example of:
a) mutualism
b) commensalism
c) parasitism
d) competition
Thank you for your help (:
The monarch butterfly and the local milkweed plants live in harmony. The nectar from the flowers is enjoyed by the monarch butterflies, who also aid in plant pollination. Thus, option B is correct.
What is the role of commensalism in monarch butterfly?The intestine of the monarch caterpillars is invaded by a parasite. The adult butterfly starts to ooze fluid from its body and dies if it emerges from the pupal stage with a serious parasite infestation.
The milkweed grows successfully as a result of the effective pollination, providing more nurseries for the vital “fourth generation” of monarchs.
The butterflies do not fly as well or live as long as those who are uninfected, even if they do survive, as in the case of a mild illness.
Therefore, commensalism is an instance of a monarch butterfly stores a poisonous chemical from the milkweed plant in its body.

Give and example of functional differences between cells belonging to two different parts of the human body???
Answer:Cells of the digestive system are vastly different in structure and function from cells of the skeletal system. Cells of the body depend on each other to keep the body functioning as a unit.
Cells of the digestive system are different in nature and function from cells of the skeletal system. Cells are depend on each other to keep the body as a unit.
What is cell theory?Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Types of cell:
Prokaryotic Cell
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.
Eukaryotic cell
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organalle level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore, Cells of the digestive system are different in nature and function from cells of the skeletal system. Cells are depend on each other to keep the body as a unit.

What kinds of data do scientists use to study climate?
Answer:
When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.

how does the concept of apoptosis relate to sally cancer cells compared with normal cells ?
Answer:
Apoptosis is defined as a programmed cell death and plays very important role in the removal of cancerous cells. Apoptosis is the process in which cell undergoes several processes and attempt sui-cide. Apoptosis do not cause any harm to human cells as it removes only unwanted cell.
Apoptosis can prevent cancerous cells by telling unwanted growth of cell to self destruct. Cancer cells are formed due to proliferation of cells and ignore the signals of self destruction to prevent apoptosis.
In Sally's case also, cancer cells ignored the signal of apoptosis and a tumor was found in her colon.

A student performs an investigation
to determine if keeping plants in a
greenhouse will reduce the amount
of water lost to evaporation. The
student hypothesizes that if a plant
is in a closed, humid environment,
then less water will be lost to
evaporation. The student places the
plants in beakers of water and then
sets some beakers inside and some
beakers outside of a greenhouse,
She then measures the amount of
water lost from each beaker, Which
table should the student use to
collect the data needed to test her
hypothesis?
Answer:
C
Explanation:
Measure the volume of the water of the plants in and outside. Then note how many days have passed
Table C should be used to collect the data needed to test her hypothesis. Every time the temperature rises, so does the rate of evaporation.
What is evaporation?Water moves from either a liquid form to something like a gaseous state through evaporation. Water boils at a temperature of 100 degrees Celsius, yet it evaporates relatively slowly at 0 degrees. Every time the temperature rises, so does the rate of evaporation.
Depending on the temperature and the quantity of water that has to evaporate, water evaporates at different speeds. Take a desert, for instance, and consider how little evaporation occurs there despite it being quite hot. Table C should be used to collect the data needed to test her hypothesis. When a liquid changes from a liquid to a gas, evaporation occurs. The reaction starts when the liquid's molecules receive energy in the shape of heat.
Therefore, the correct option is option C.

Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.
