List the steps of Photosynthesis in order.
Answers
Answer:
Step 1
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Step 2
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Step 3
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
Step 4
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
Chemical reactions occur with the help of protons from the water molecules and electrons from the chlorophyll molecules to produce Adenosine Triphosphate (ATP). ATP provides energy for cellular reactions and Nicotinamide Adenine Dinucleotide Diphosphate (NADP), which is integral in plant metabolism.

The removal of a keystone species from a community will initiate changes in that community's structure and typically results in __________.
Answers
The removal of a keystone species from a community will initiate changes in that community's structure and typically results in a reduction in diversity or collapse of community structure.
This is a kind of cascading effect or a domino effect, where other species are affected due to the absence of the keystone species. This can lead to significant changes in the ecosystem, such as a decline in biodiversity and changes in the food web.
An example of this is the intertidal sea star Pisaster ochraceous. It is found in the northwestern United States. In a study, the sea stars were experimentally removed from the intertidal zone where they lived. As a result, populations of their prey (mussels) increased, altering the species composition of the community and sharply reducing species diversity. When the sea stars were present, about 25 species of barnacles and algae were found in the lower part of the intertidal zone, but when they were missing, the mussel population expanded downward and almost entirely replaced these other species.

depurination of purine bases results in an apurinic site. assume a single depurination event occurs in the gc base pair of the sequence below and is not repaired. then, if two rounds of replication occur, which of the following dna sequences will exist after two rounds of replication? remember that when dna polymerases encounter an apurinic site, most often an a is incorporated into the newly synthesized strand. assume this is true for the sequence below. ...tact... ...atga...
Answers
After a single depurination event occurs in the GC base pair of the given DNA sequence "...TACT... ...ATGA...", an apurinic site will be generated. During replication, the DNA polymerase will incorporate an A nucleotide in the newly synthesized strand opposite the apurinic site.
Thus, after one round of replication, the two resulting DNA strands will be:
Original strand: ...TACT... ...ATGA...
Newly synthesized strand: ...TAC(A)... ...ATGA...
During the second round of replication, the newly synthesized strand from the first round will act as the template strand for further replication. As a result, the two resulting DNA strands after the second round of replication will be:
Original strand: ...TACT... ...ATGA...
Newly synthesized strand 1: ...TAC(A)... ...ATGA...
Newly synthesized strand 2: ...TAC(A)... ...ATGA...
Therefore, both newly synthesized strands will have an A nucleotide opposite the apurinic site, resulting in the same sequence.

Answers
Pulmonary Circulation and Systemic Circulation are the types of circulation
1. Pulmonary Circulation:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide.
The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body. It sends the oxygenated blood out to cells and returns deoxygenated blood to the heart.
2. Fertilization:
Fertilization is a Reproductive process in which a male sex cell (sperm) unites with a female sex cell (egg). During the process, the chromosomes of the egg and sperm will merge to form a zygote, which will divide to form an embryo.
3. Systemic Circulation:
In the systemic loop, oxygenated blood is pumped from the left ventricle of the heart through the aorta, the largest artery in the body.
The blood moves from the aorta through the systemic arteries, then to arterioles and capillary beds that supply body tissues. Here, oxygen and nutrients are released and carbon dioxide and other waste substances are absorbed.
4. Vegetative reproduction:
Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cuts off the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.

Why do you think Los Angeles City was the first large settlement in the area, followed by LA County, and why there are more and more people further and further out?
Answers
Los Angeles City was the first large settlement due to its location, natural harbor, and water availability. Expansion followed land availability and demand for affordable housing.
Los Angeles City was the principal huge settlement nearby because of a few elements, including its area close to the coast, its regular harbor, and the accessibility of water from the Los Angeles Stream. These variables made the region appealing for settlement and worked with the development of exchange and business. As the city developed, so did the encompassing regions, prompting the arrangement of Los Angeles Area.
The development of Los Angeles and its encompassing regions can be credited to a few elements, including the accessibility of land, the development of the transportation organization, and the rising interest for reasonable lodging. As the populace developed and metropolitan regions turned out to be more packed and costly, individuals started to move endlessly farther to track down more reasonable lodging and bigger parts.

The cell membrane of animals is much thicker than those in plants.
O Vacuoles in plants are much larger than those in animals.
o Animal cells do not have chromosomes.
Plant cells do not have chloroplasts.
Answers
Answer:
The correct answer is: Vacuoles in plants are much larger than those in animals.
Explanation:
The cell membrane of animals is not thicker than those in plants. In addition, plant cells have a thick cell wall surrounding the cell membrane that is made of cellulose and provides great protection against osmotic and mechanical stress.
Vacuoles in plants ARE much larger than vacuoles in animals, because plant cells require much more water and other substances to function properly. Animals, on the other hand, can ingest water and nutrients through food.
Animal cells DO have chromosomes. Every organism has chromosomes in their cells: prokaryotes have one single circular chromosome, while eukaryotes have many linear chromosomes (humans, for example, have 46 chromosomes).
Plant cells HAVE chloroplasts, as these organelles are crucial, since they participate in the process of photosynthesis - which is fundamental for the nourishment of the plant.

The graphs above show a change in distribution of beak phenotypes X, Y, and Z over 10 generations. Notice that Beak X completely disappears from the population by Generation 5, but reappears by Generation 10. Could this occur in nature? How?
Answers
A, Yes, the alleles for Beak X could remain in the population as a recessive gene.
What is the rationale behind it?Recessive genes. The alleles for beak X could remain in the population as recessive genes. This means that birds with beak X would still be able to pass on the genes for beak X to their offspring, even if they themselves did not have beak X. If two birds with the recessive gene for beak X mated, their offspring would have a 25% chance of having beak X.
Mutation. The birds could mutate their beaks in response to a change in the environment. This could lead to the appearance of beak X, even if the gene for beak X was not present in the population before.
Random chance. Genetic mutation is so frequent that it is possible for beak X to reappear randomly by generation 10. This is especially likely if the environment is changing and there is a selective advantage for birds with beak X.
In conclusion, it is possible for beak X to reappear after 5 generations in nature. This could happen through the inheritance of recessive genes, mutation, or random chance.

O agriculture
O increased hunting efficiency
Answers
Agriculture was a major cause of the adaptive success characterized by population explosion. Agriculture allowed people to settle in one place and produce a reliable food supply, which led to population growth.
Agriculture is the science, art, and business of cultivating soil, producing crops, and raising livestock. This practice is one of humanity's oldest activities, dating back at least ten thousand years. Before agriculture, people were hunters and gatherers, but agriculture allowed people to settle in one place and develop more complex societies. Agriculture also provided a dependable food source, allowing the human population to expand rapidly.
Over time, agriculture progressed as humans discovered new ways to cultivate crops and raise animals. Agricultural practices and technology have advanced to the point where we can produce large amounts of food with minimal effort. Modern agriculture uses a variety of techniques, including mechanization, fertilizers, and genetic engineering, to increase yields and decrease labor costs. This allows us to feed a rapidly growing global population.
