Lichens and mosses are pioneer species that help make the environment suitable for subsequent plant growth by breaking down rock into soil and enriching the soil with nutrients, such as nitrogen, through their symbiotic relationships with cyanobacteria.
These organisms are known for being the first to colonize areas of bare rock or soil after an event that leaves an area barren. Lichens, which are symbiotic associations between a fungus and a photosynthetic partner like algae or cyanobacteria, are capable of leaching nutrients from substrates and helping in soil formation. Similarly, mosses establish relationships with nitrogen-fixing cyanobacteria, contributing nitrogen to the soil, making it more hospitable for subsequent plant growth including grasses and shrubs.
An endurance runner begins experiencing muscle soreness towards the end of a long race.
Explain, in detail, what is happening in her muscle cells. Your answer should include the
molecule(s) that are missing, how this is altering cell respiration, and what the cause of
her soreness is.
Answer and Explanation:
The cells of the runner respire through anaerobic respiration due to inadequate oxygen leading to formation of lactic acid. Under these conditions lactic acid accumulates in the muscles which might cause fatigue and result in muscle soreness and cramps. Lack of enough oxygen makes the cells to respire anaerobically altering cell respiration.
Final answer:
During intense exercises like a long race, endurance runners' muscles switch from aerobic to anaerobic respiration, producing ATP via lactic acid fermentation. The accumulation of lactic acid can cause immediate muscle fatigue and soreness.
Explanation:
During a long race, an endurance runner's muscle cells start to experience an intense demand for ATP (Adenosine Triphosphate), the molecule required for muscle contraction. Initially, ATP is produced via aerobic respiration, a process that efficiently generates ATP but requires oxygen.
As the race progresses, the oxygen supply to the muscles may not keep pace with demand, and the muscles switch to anaerobic respiration, specifically lactic acid fermentation, to meet their energy needs.
This process does not require oxygen and can produce ATP quickly, albeit less efficiently than aerobic respiration. One of the byproducts of lactic acid fermentation is lactic acid.
The accumulation of lactic acid in the muscle cells can lead to a decrease in pH (increasing acidity), which can impair muscle function and contribute to the sensation of muscle fatigue and soreness during and immediately after intense exercise.
the curved paths of global winds and surface currents are caused by?
The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.
Final answer:
The curvature of global winds and surface currents is mainly due to the Coriolis effect, while unequal heating of Earth's surface and the shape of ocean basins also play a role.
Explanation:
The curved paths of global winds and surface currents are primarily caused by the Coriolis effect, which is due to the rotation of the Earth. This effect causes moving air and water to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating curved paths. In addition to the Coriolis effect, unequal heating of Earth's surface by the sun (more solar radiation at the equator than at the poles) and the shape of ocean basins also contribute to the patterns of surface currents. Together, these factors create distinct wind belts and cause the moving air and water to flow in specific directions.

1. By examining the fin of a primitive fish, scientists
have found similarities in bone structure to that of
modern day reptiles, birds, and mammals. What
type of evidence does this describe?
The question discusses the concept of homologous structures, which are similarities in anatomy across different species pointing to a common ancestor. This evidence supports the theory of evolution through common descent, indicating that species evolve divergently from a shared origin.
Explanation:By examining the fin of a primitive fish and noticing similarities in bone structure to modern day reptiles, birds, and mammals, scientists are observing homologous structures. Homologous structures are examples of an anatomical similarity that results from organisms sharing a common ancestor. This type of evidence points towards the evolutionary theory that suggests modern species share a common ancestor. Over time, this ancestral lineage diverged through evolutionary changes, leading to the variety of species we see today. These structures have evolved in different ways to suit the needs of different species but retain an underlying structural similarity that hints at their shared origins.
Homologous structures are not limited to the skeletal system; they can also include other anatomical features that demonstrate a common ancestry. The presence of these structures across different species provides a compelling argument for the concept of evolution through common descent, showcasing how evolutionary pressures and environmental changes have sculpted various forms from an ancestral blueprint.

What is the real story of Thanksgiving? GIVE A LOT OF DETAIL
Others pinpoint 1637 as the true origin of Thanksgiving, owing to the fact Massachusetts colony governor John Winthrop declared a day of thanks-giving to celebrate colonial soldiers who had just slaughtered 700 Pequot men, women, and children in what is now Mystic, Connecticut.
The famous first Thanksgiving took place in 1621 and involved the Pilgrims, Indians, and a feast. The Pilgrims faced challenges upon arriving in an unknown land but built trust with the indigenous people.
Explanation:The Real Story of ThanksgivingThe famous "first" Thanksgiving took place in September or October, 1621. The Pilgrims had killed a large number of ducks and geese and Massasoit arrived with about one hundred Indians who later killed five deer to add to the feast. The participants ate with their fingers and sprawled on the ground as they consumed the feast. There was no pumpkin pie or cranberry sauce, and no eating utensils except knives.
William Bradford's narrative recounts the challenges faced by the Pilgrims when they arrived in an unknown land. They faced harsh winters and dangerous storms. However, they formed a relationship with the indigenous people, including Squanto, who proved trustworthy and helpful.
The step in photosynthesis where organism capture CO2 in order to convert it into glucose
Explanation:
This step is called Carbon fixation.
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and inorganic carbon dioxide while oxygen (from the light reaction) is released.
Further Explanation:
This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This begins in the thykaloids, where pigment molecules like chlorophyll reside. The chloroplast is a membrane-bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.
Here, water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
In the Calvin Cycle:
During the initial stage, three molecules of ribulose bisphosphate, RuBP are reduced and carbon is fixed from an inorganic CO2 to an organic form by the enzyme RuBisCO. With every molecule of CO2 fixed, 2 molecules of 3-phosphoglyceric acid are produced. 3-PGA is a 3 carbon molecule with a phosphate attached.
This is called carbon fixation.

The Calvin Cycle or light-independent reactions of photosynthesis is where organisms capture CO2 to convert into glucose. This is accomplished using the enzyme RuBisCO and energy carried by ATP and NADPH. After three cycles, a sugar molecule G3P leaves the cycle to become part of a carbohydrate molecule.
Explanation:The step in photosynthesis where organisms capture CO2 to convert it into glucose is called the Calvin Cycle or light-independent reactions. During these reactions, an enzyme called RuBisCO fixes CO2 from the environment, combining it with an organic compound, RuBP. The resulting six-carbon compound is then broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into a type of sugar called G3P. After three cycles of the Calvin Cycle, one of the G3P molecules leaves to become part of a carbohydrate molecule such as glucose, while the remaining G3P molecules continue in the cycle to be formed back into RuBP to react with more CO2.

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane components, including the nucleus, endoplasmic reticulum and golgi apparatus in what would become eukaryotic cells. The evolution of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. The endomembrane system includes the endoplasmic reticulum. Which statement does NOT describe the endoplasmic reticulum (ER)?
A) The ER is an extension of the nuclear envelope.
B) The ER serves as a transport network for the proteins produced in its membrane.
C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
D) The ER serves a role in protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage
Explanation:
False: C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.
During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.
Further Explanation:
The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.
Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation

Smithsonian Magazine: 14 fun facts about marine bristle worms
Polychaete worms are a diverse class of animals with at least 10,000 species.
They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.
Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.
National Ocean Service: What is a bivalve mollusk?
Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.
Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.
They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.
These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.
There are over 9000 species.
Marine Education Society of Australasia: Echinoderms
Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.
They are found on the sea floor and include starfish, sea cucumbers and sea urchins.
They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.
There are over 7000 species.

Due to their structure, phospholipids are best suited to make the cell membrane in organisms.
Final answer:
Each phospholipid molecule is composed of a hydrophilic head, which includes a phosphate group attached to a glycerol molecule, and two hydrophobic tails, which are the long hydrocarbon chains of fatty acids. These molecules are essential for forming the cell membrane's phospholipid bilayer, crucial for the cell's structure and function.
Explanation:
Composition of Phospholipids
Each phospholipid is a crucial component of cell membranes, consisting of a polar, phosphate-containing hydrophilic head and two nonpolar, long-chain hydrophobic tails. The hydrophilic head group is attached to a glycerol molecule. This configuration is essential for the formation of the cell membrane's phospholipid bilayer, where the hydrophilic heads face outward towards the aqueous environment, and the hydrophobic tails face inward, away from water. The glycerol backbone serves as the anchor for both the hydrophilic head, which includes the phosphate group, and the hydrophobic tails, which are composed of either saturated or unsaturated fatty acids. These fatty acid chains are long hydrocarbon chains that contribute to the phospholipid's insolubility in water.
