Answer:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

Explanation:
Explain how the method of nutrition used by wild pine differs from the method of nutrition used by other organisms (animals)
Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
how can an understanding of osmosis be important in developing methods for the same storage of food?
Osmosis is also used for preserving fruits and meats, though the process is quite different for the two. In the case of fruit, osmosis is used to dehydrate it, whereas in the preservation of meat, osmosis draws salt into it, thus preventing the intrusion of bacteria.

6. explain the relationship between enzymatic active sites & the
catalytic cycle of an enzyme
Answer: To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. ... The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). A substrate enters the active site of the enzyme.

hans and zacharias janssen contribution to cell theory
Answer:
1590’s
What year did Hans and Zacharias Janssen contribute to the cell theory? Hans and Zacharias Janssen are known for inventing the compound optical microscope. They made it in the 1590’s. This contributed to “The Cell Theory” by making it easier and more practical whilst observing cells.
Explanation:
Cell theory states that all biological organisms are made up of cells, which is the structural and functional unit of life.
Scientists Hans and Zacharias Janssen invented the compound microscope that played a vital role in observing cellular functions.
Hans and Zacharias Jansen invented the compound microscope, which consisted of the eyepiece and an objective lens.
The scientists discovered the compound microscope in the late 16th century, which then helped many scientists to magnify and observe the microscopic structures.
Thus, the Janssens discovered the compound microscope.

what is the effect of water temperature on corals from inshore and offshore reefs?
Answer:
When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.
Explanation:
When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.
What are coral reefs?A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.
The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.
Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.
When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.
The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.
Thus, this is the effect of water temperature on corals from inshore and offshore reefs.

List 4 examples of limiting factors described in the reading and label each if it would be considered an abiotic or biotic limiting factor.
Answer:
Explanation:food, water, habitat, and mate.
Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.
What are biotic and abiotic factors?The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.
• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings.
What are the limiting factors?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.
Limiting factors might be a result of the population density or might be dense-independent.
When talking about dense-independent limiting factors we are referring to
abiotic factors, such as temperature, pH, salinity, humidity, radiation, etcetera.natural disasters like fires, volcanic eruptions, flooding, etceterahuman impactWhen talking about dense-dependent limiting factors we are referring to biotic factors and the interactions established between species that control other species' growth.
These are, for instance,
competition, parasitism, and predation
Each species carries out a different role in these interactions.
These relationships and the results are what determine the destiny of the populations and their size.
Now, since I do not have the text, I will suggest a few examples of limiting factors. Take a look at them and then look for some other examples in your reading.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

When the phenotypic effect of alleles at one gene are masked by alleles of another gene.
In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.
It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.

Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
