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.

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.

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.

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.

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.

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.
One of the most common plants in Atlantic salt marshes is cordgrass. periwinkle snails cling to the top of tall cord grass is during high tide. The tall cord grass is provide protection from the snails predators such as blue crab. well the snails do not be directly on cordgrass the snails can damage the cord grass when they grays and algae and fungi that grow on the grasses. if the snail populations grow too large they can decrease cord grass growth.
Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.
Biotic factors - The living components or the living things that are present in the ecosystem that shapes the environment are known as biotic factors. Examples are plants, bacteria, algae, birds, fishes etc.
A ecosystem runs through the interaction of biotic and abiotic component. Biotic supplements acts as a fuel that supports the bacterial growth.
Periwinkle snails graze on the top of the cordgrasses to escape from their predators blue crab. They graze on the fungi and algae that is inhabitant on top of the grass, they do not feed directly on the cordgrass
While grazing they actually damage the cordgrass by spreading the fungal infection.

B. when the allele of one gene masks the genotype of another gene
C. when the allele of a gene changes the phenotype of another allele of that gene
D. when the allele of one gene masks the phenotype of another gene
The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene
Definition:
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.
