Answer:
It depends It is important to understand the fact that the number of chloroplasts in an elodea cell can vary. The main idea is that there are not a fixed number of chloroplasts in elodea cell. This signifies that there is not a specific amount in each cell.

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.
Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?
0 Lactase is necessary for survival of all organisms
0 All living things share a common code-DNA
0 Lactase is not regulated by external environments.
It is not possible for it to be the same in different species
Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

What are the three ways that minerals can form?
They are formed from the cooling and solidification of molten magma. that is the primary means of formation.
They could be precipitated out of solution.
They are also formed during metamorphism, under high temperature and pressure, minerals recrystalize and form new minerals.

Purple flowers are dominant to white flowers. Which of the following phenotypes would (PP) reflect?
A. Purple
B. White
Answer:
A. Purple
Explanation:
Since purple flowers are dominant to white flowers, the letter for it need to be capital too to signify dominance. So purple flowers is PP.

During one part of the water cycle, heat from the Sun causes liquid water to change into water vapor, which rises into the atmosphere.
Which statement best describes the reverse of this process?
a) As liquid water falls from the atmosphere to land, it turns into a gas
b) As the Sun's rays warm solid ice, it begins to melt into liquid water.
c) As liquid water from streams and groundwater drains into large bodies of liquid water, it turns to gas.
d) As water vapor meets cooler air, it changes into droplets of liquid water that return to Earth's surface.

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]

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.

what provides new variation
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.
