How can cells from the same organism have such different shapes and functions?
Answer:
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. B Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
Explanation:
Answer:
Because cells are not only characterized by by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies.

Five hundred cockroaches of one species were sprayed with a new insecticide. Twenty-four hours later nearly all the cockroaches were dead. A few, however, survived. This outcome illustrates which one of darwin’s key ideas about natural selection and variation?.
Answer:
This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.
The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.
Which question most closely relates to the biologist's observations and collected data?
Are the golden frogs succumbing to a fungal infection?
Answer:
are the frogs dying off because of the mines waste water?

Select the correct answer from each drop-down menu. the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.
The DNA of humans and mice is almost 92% similar. This similarity indicates that mice share a common ancestor with humans. Mice have a tail, while humans have a tailbone.
Why do humans share DNA with mice?Humans and mice don't look alike, but both species are mammals and are biologically very similar. Almost all of the genes in mice share functions with the genes in humans.
That means we develop in the same way from egg and sperm, and have the same kinds of organs.
Thus, Mice have a tail, while humans have a tailbone is correct.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to determine the p squared value?
The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
What is a recessive phenotype?A recessive phenotype is a phenotype which expresses the recessive trait of a gene.
The recessive phenotype is always h0m0zygous for that triat to be expressed.
In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:
p^2 + 2pq + q^2 = 1where;
p^2 is the h0m0zygous dominant phenotype frequency2pq is the heterozygous phenotype frequencyq^2 is the h0m0zygous recessive phenotype frequencyTherefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Which is included in a lysogenic cycle? early lysis of the host cell the creation and assembly of viral particles the appearance of viral infection symptoms a period of genetic integration
The lysogenic cycle includes the early lysis of the host cell that involves the incorporation of the viral genome into the host cell genome.
What do you mean by the Lysogenic cycle?
A lysogenic cycle may be defined as a method by which a virus can replicate its DNA using a host cell.
In the lysogenic cycle, the viral DNA gets integrated into the host's DNA but viral genes are not expressed. Lysogeny is characterized by the integration of the bacteriophage nucleic acid into the host bacterium's genome.
Therefore, the lysogenic cycle includes the early lysis of the host cell that involves the incorporation of the viral genome into the host cell genome.

Which statement best describes the effect of color on energy absorption and reflection?
Light colors reflect more and absorb less than dark colors.
Light colors reflect less and absorb more than dark colors.
Light colors absorb and reflect more than dark colors.
Light colors absorb and reflect less than dark colors.
The answer is A) Light colors reflect more and absorb less than dark colors.
Because remember, white is the absence of color (reflect) and black is every color (absorbs) :D
Light colors reflect more and absorb less than dark colors. The correct option is A.
What is reflection?When two different media come together at an interface, a wavefront might change direction so that it returns to the first medium, which is known as reflection. The reflection of light, sound, and water waves are typical examples.
It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it.
The darker colours absorb more of the various light energy wavelengths, whereas white or light-colored objects reflect the majority of these wavelengths, which is why heat absorption depends on hue. As a result, black absorbs all light's wavelengths while reflecting none.
Thus, the correct option is A.
