Answer:
resolving power.Explanation:
The principal limitation of the light microscope is its resolving power.
Using an objective of NA 1.4, and green light of wavelength 500 nm, the resolution limit is ∼0.2 μm. This value may be approximately halved, with some inconvenience, using ultraviolet radiation of shorter wavelengths.
18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.
Answer:
c
Explanation:
they would have diffrent gene versions and protines to get their colors
In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.
What is the petal shape dependent on?Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.
Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

Some organisms have a large geographic range. For example, the Norway rat lives on every continent except Antarctica A population of Norway rats is the number of rats in one particular area. Do you think it's scientifically possible for a population of Norway rats in North America to carry different genetic mutations than a population of Norway rats in Africa? Do you think it's possible that they carry some of the same mutations? What types of information can scientists learn by studying the genomes of these two populations of rats?

What are the consequences and causes of Space junk that affect the Earth's environment?
Answer:
The main threat to our weather from space junk is rather indirect: the density of the junk may become so great that it could hinder our ability to use weather satellites, and hence to monitor weather changes caused by our own ground-based pollution.

How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
They cancel each other out. There are 12 Carbon molecules on each of the equation and 54 Oxygen on each side So their carbons cancel each other out on each side of the equations as the oxygen.

The diagram below shows the cell cycle. Which type of cell division is indicated by the processes happening in C and D?
Answer:
This process is mitosis
maybe this will help
It might not be exactly what you are looking for but this is what I have done
The type of cell division indicated by the processes happening in C and D would be mitosis.
Mitosis is the division of vegetative cells and results in the production of 2 genetically identical daughter cells.
During mitosis, sister chromatids separate into opposite poles and each group of chromatids forms the genetic materials for daughter cells that will become independent when the parent cell undergoes cytokinesis - the division of the cytoplasm.
C in the image represents the metaphase of mitosis where chromosomes align at the center of the cell and get engaged by spindle fibers. D represents the anaphase where sister chromatids have been pulled apart and begin to migrate to opposite poles through the contraction of spindle fibers.
After completing their migration to the poles, the chromatids decondense, and a nuclear envelope appears around each of them. The cytoplasm then divides into two for new independent daughter cells to be formed.

Which of these statements about ocean water is always correct?
a.) Its area is less than the area of freshwater.
b.)Its salinity is less than the salinity of freshwater.
c.) Its density is greater than the density of freshwater.
d.)Its temperature is greater than the temperature of freshwater.
Answer:
c.) Its density is greater than the density of freshwater.Explanation:
Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.
The freezing point of seawater decreases as salt concentration increases.
Answer:
C.) Its density is greater than the density of freshwater.
Explanation:
Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

use of scientific and non-scientific techniques
in forensic science. Considering what you've
learned, identify what is science, what clearly
is not science, and what resembles science
(but doesn't meet the criteria for science). For
each of these, make sure to give real world
examples and explain why it is either a

Answer:
Knowledge gain through observation and experimentation.
Explanation:
Science is the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. That knowledge which can be gain through observation and experimentations is considered as scientific knowledge and those knowledge which can be attain through other sources not observation and experiments is known as non-scientific knowledge so we can say that observation and experiments provide scientific knowledge.
Which scientists do you think had they biggest impact on the discovery of DNA and why
Answer:
He was paving the way for a discovery that would change the world. Scientists James Watson and Francis Crick were famously the first to work out the structure of DNA, and Rosalind Franklin and Maurice Wilkins are often credited for capturing the images of the molecule that made this possible.
Answer:
I believe that James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin made the biggest impact on the discovery of DNA.
Explanation:
At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. These 4 people worked together and made a significant discovery.

How are meiosis and mitosis different?
Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Explanation:
:)
Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

What is the reason water has so many special properties?
Answer: Water has many unusual properties
Explanation: Water has many unusual properties because of its polar covalent bonds. Oxygen has a larger electronegativity than hydrogen, so the electron pairs are pulled in closer to the oxygen atom, giving it a partial negative charge. Subsequently, both of the hydrogen atoms take on a partial positive charge.
