Which of the following results when homologous chromosomes cross over in meiosis?
Two sister chromatids get tangled, resulting in one re-sequencing its DNA.
DNA repair machinery alters maternal alleles so they match paternal ones
Two sister chromatids exchange identical pieces of DNA.
Corresponding segments of non-sister chromatids are exchanged.
When homologous chromosomes cross over in the process of meiosis, the corresponding segments of the non-sister chromatids are exchanged. Thus, the correct option is D.
What is Crossing over?
Meiosis is the process of cell division in which the chromosomal content of the cell reduces to half. This division is also known as reductional division. Meiosis is divided into two parts: Meiosis I and Meiosis II.
Meiosis I is divided into four phases which are Prophase I, Metaphase I, Anaphase I, and Telophase I. Prophase I is further divided into five stages which are Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. Crossing over of chromosomes takes place during pachytene stage.
Crossing over or the chromosomal crossover is the exchange of the genetic material during the process of sexual reproduction between the two homologous chromosomes' non-sister chromatids which results into the formation of recombinant chromosomes.
Therefore, the correct option is D.

Explain why cellular respiration releases energy as an overall chemical reaction
Answer:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP
In other words:
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see.
commensalism, parasitism, or mutualism
Answer: This would be an example of mutualism.
Explanation: Mutualism is when, in a certain situation, benefits both organisms. The gazelles and ostritches in this situation are both watching for predators and are making sure to alert each other to the danger that could spring nearby. Both of these animals can locate predators in different ways. Ostritches are capable of seeing predators from in the tall grasses, while the gazelles are able to hear predators with their great hearing. Together, these two creatures make a great defense. Both the gazelles and ostritches benefit. This is known as mutualism.

I need two paragraphs explaining how carbon is transferred within and between organisms and the environment.
Answer:
Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.
For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Another plant is said to be heterozygous for flower color. What does this mean?
Answer:
Depending on how the gene works, it might result in an orange flower or in a flower that’s just yellow or in one that’s just red—but with the potential to have offspring of a different color. Such a flower would be said to be heterozygous for flower color, because it’s got a copy of one yellow allele and one red allele.
Explanation:
A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is
Likely playing a role in this rapid evolution for mosquitos?
A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that
information on to offspring. This increases the survival of those offspring
as well.
D)
Mosquitos have the ability to detect areas with high pesticide loads and
can avoid those areas. This allows mosquitos to survive and reproduce with
more success.
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.

points on Earth's orbit.
Galileo created a model showing the epicycles of the planets, which explained retrograde motion.
Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all
things.
U Galileo explained that people did not see stellar parallax because the stars were simply other suns that are very
far away.
Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Intro
Done
Answer:
- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.
-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Explanation:
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.
