Answer:
Natural selection allowed physically fit dark colored moths to survive and mate to produce more physically fit offspring.
Explanation:
Due to their dark color, the dark colored moths were not identified by their predators easily. However, the light colored moths were easily identified and preyed upon.
In this way the population of light colored moths reduced largely, thereby allowing more and more mating of light colored moth with dark colored moth or mating of dark colored moth with another dark colored moth so that environmentally fit offspring could be produced which have the capability to save themselves from the predator or any other harm.
In this way natural selection allowed a shift in color of moth from lighter shade to a darker shade.
how does light travel?
A. light only travels in a vacuum and travels faster when the sound is moving
B. light on only travels in a medium and light travels faster when a Sound Source is stationary
C. light can travel in a vacuum in the speed varies depending on whether the source is moving or stationary
D. light can travel in the air or a vacuum and the speed is constant weather the light source is stationary or moving
Answer: The correct answer is option(D).
Explanation:
Light travels in a straight line as a wave. It does not require any medium or material to travel like sound waves which means it can travel in vacuum.The speed of the light from the special theory of relativity is a constant value of [tex]34\times 10^{8} m/second[/tex].
Hence, the correct answer is option (D).

Charles Darwin studied finches on the Galapagos Islands. While the finches on all the islands came from the same ancestors, the distance between the islands was too great to allow finches from different islands to interbreed. Over time, the size of the finches on the different islands remained the same, but the shape and size of their beaks changed, as shown here. This adaptation helped the finches find food on their particular island. The change in the size and shape of the finches’ beaks was MOST LIKELY caused by A) geographic isolation B) a change in climate. C) endangerment of the species. D) a decrease in the mutation rate.
Answer:
a) geographic isolation

• In what way do you think the location of the foramen magnum relates to the movement of each species? ...?
Answer:
The location of the foramen magnum can help in the determination of the positions of the spine, which further helps in determining that how each of the species walk.
Explanation:
The foramen magnum is an essential characteristic in bipedal mammals. The foramen magnum suggests the position of the spine in association with the head, and thus tells that whether the organism is bipedal or move in some other manner.
The foramen magnum in humans is located in the center, facing downwards straightforwardly that permits the humans to stay oriented vertically for bipedalism. However, in case of other apes, the foramen magnum is located towards the skull back.

If the corpus callosum is severed, how might this affect the way we perceive the world?
The corpus callosum is a part of brain that lies above the thalamus and connects the two hemispheres of the brain. It maintain link of communication between two of them. Its function is to transfer neural messages in between right hemisphere and left hemisphere. The severed corpus callosum will act as having two brains in one body. Each part of the hemisphere will have its own perception, speech and thought. There is a possibility that the individual wears a pant due to the signals from one hemisphere and the other hemisphere of brain signals to down the pant. There is a lack of coordination in the functions performed if corpus callosum is severed.

Why does darkness affect the light-independent reactions of photosynthesis?
Plants stop their daytime activities and rest during the night much like animals do.
Light independent reactions need more heat energy than nighttime temperatures often provide.
Light independent reactions require the energy gathered in the thylakoids.
Mitochondria produce sugars more effectively in the darkness than chloroplasts do.
The right answer is Light independent reactions require the energy gathered in the thylakoids.
* The dark phase corresponds to the phase of assimilation of CO2 which uses the energy molecules produced during the clear phase and which is carried out cyclically. This cycle is called the Calvin cycle and it takes place in the stroma of the chloroplast.
The assimilation of CO2 is done in four main stages, the first three of which take place within the Calvin cycle:
-CO2 fixation (carboxylation).
-Carbon reduction fixed.
-Regeneration of the CO2 acceptor.
-Synthesis of sugars.
* A thylakoid, or thylakoid membrane, in a chloroplast, is a flat membranous sac containing chlorophyll, or in other words, it is a cell membrane within the plant chloroplast that photosynthesizes. The thylakoid of a bacterium is also called the chromatophore.
A thylakoid is a membrane compartment within chloroplasts and cyanobacteria. They are the place of light-dependent reactions of photosynthesis. The thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen (in the biological sense).

Which diagram best represents mitotic cell division?
The diagram that best represents mitotic cell division is diagram C. 2n -> 2n, 2n. The correct option is c.
What is mitotic division?The cell cycle phase known as mitosis is when a cell's nucleus divides into two daughter nuclei, each of which contains an equal amount of genetic material.
A single cell divides into two identical daughter cells during the process of mitosis (cell division). One diploid cell divides once into two identical cells during mitosis. Mitosis is primarily used for cell growth and the replacement of worn-out cells.
The first option is fertilization, which involves joining two haploid gametes to create a diploid zygote. The second is meiosis I, which produces only two haploid daughter cells from a single diploid cell.
Therefore, the correct option is diagram c.

Smallpox is a virus that causes a rash that then turns into painful blisters. The last known case of smallpox was in 1977. What is the best explanation for the eradication of smallpox? People are exercising more than they used to. Genetic testing determines who is more prone to smallpox. There was an increase in antibacterial products. A vaccine was developed.
Answer:
The correct answer would be a vaccine was developed.
A vaccine is a substance (usually a heat-killed or attenuated pathogen or antigen) which is injected into the body of the person in order to produce antibody and thus it develops immunity against that specific pathogen or disease.
A vaccine for smallpox was developed in 1796 by Edward Jenner which results in global eradication of smallpox.

6 letter word: a stack of thylakoids in a chloroplast
In a chloroplast, thylakoids are disc-shaped structures where photosynthesis occurs. These thylakoids are stacked into a granum. The surrounding fluid-filled space is known as the stroma.
Explanation:In a chloroplast, a thylakoid is a disc-shaped, membrane-bound structure where the light-dependent reactions of photosynthesis happen. Thylakoids are assembled into stacks which are called a granum (pl. grana). The fluid-filled space that surrounds the grana is called the stroma.
Each thylakoid stack or granum, are like interconnected and stacked fluid-filled membrane sacs. The thylakoid membranes contain chlorophyll, which is vital for the process of photosynthesis.
